I am trying to open an image / picture in the Gallery built-in app from inside my application.
I have a URI of the picture (the picture is located on the SD card).
Do you have any suggestions?
This is a complete solution. I've just updated this example code with the information provided in the answer below by #mad. Also check the solution below from #Khobaib explaining how to deal with picasa images.
Update
I've just reviewed my original answer and created a simple Android Studio project you can checkout from github and import directly on your system.
https://github.com/hanscappelle/SO-2169649
(note that the multiple file selection still needs work)
Single Picture Selection
With support for images from file explorers thanks to user mad.
public class BrowsePictureActivity extends Activity {
// this is the action code we use in our intent,
// this way we know we're looking at the response from our own action
private static final int SELECT_PICTURE = 1;
private String selectedImagePath;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
findViewById(R.id.Button01)
.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
// in onCreate or any event where your want the user to
// select a file
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Select Picture"), SELECT_PICTURE);
}
});
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
}
}
}
/**
* helper to retrieve the path of an image URI
*/
public String getPath(Uri uri) {
// just some safety built in
if( uri == null ) {
// TODO perform some logging or show user feedback
return null;
}
// try to retrieve the image from the media store first
// this will only work for images selected from gallery
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
if( cursor != null ){
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
String path = cursor.getString(column_index);
cursor.close();
return path;
}
// this is our fallback here
return uri.getPath();
}
}
Selecting Multiple Pictures
Since someone requested that information in a comment and it's better to have information gathered.
Set an extra parameter EXTRA_ALLOW_MULTIPLE on the intent:
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
And in the Result handling check for that parameter:
if (Intent.ACTION_SEND_MULTIPLE.equals(data.getAction()))
&& Intent.hasExtra(Intent.EXTRA_STREAM)) {
// retrieve a collection of selected images
ArrayList<Parcelable> list = intent.getParcelableArrayListExtra(Intent.EXTRA_STREAM);
// iterate over these images
if( list != null ) {
for (Parcelable parcel : list) {
Uri uri = (Uri) parcel;
// TODO handle the images one by one here
}
}
}
Note that this is only supported by API level 18+.
Here is an update to the fine code that hcpl posted. but this works with OI file manager, astro file manager AND the media gallery too (tested). so i guess it will work with every file manager (are there many others than those mentioned?). did some corrections to the code he wrote.
public class BrowsePicture extends Activity {
//YOU CAN EDIT THIS TO WHATEVER YOU WANT
private static final int SELECT_PICTURE = 1;
private String selectedImagePath;
//ADDED
private String filemanagerstring;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
((Button) findViewById(R.id.Button01))
.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
// in onCreate or any event where your want the user to
// select a file
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Select Picture"), SELECT_PICTURE);
}
});
}
//UPDATED
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
//OI FILE Manager
filemanagerstring = selectedImageUri.getPath();
//MEDIA GALLERY
selectedImagePath = getPath(selectedImageUri);
//DEBUG PURPOSE - you can delete this if you want
if(selectedImagePath!=null)
System.out.println(selectedImagePath);
else System.out.println("selectedImagePath is null");
if(filemanagerstring!=null)
System.out.println(filemanagerstring);
else System.out.println("filemanagerstring is null");
//NOW WE HAVE OUR WANTED STRING
if(selectedImagePath!=null)
System.out.println("selectedImagePath is the right one for you!");
else
System.out.println("filemanagerstring is the right one for you!");
}
}
}
//UPDATED!
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
if(cursor!=null)
{
//HERE YOU WILL GET A NULLPOINTER IF CURSOR IS NULL
//THIS CAN BE, IF YOU USED OI FILE MANAGER FOR PICKING THE MEDIA
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
else return null;
}
hcpl's methods work perfectly pre-KitKat, but not working with the DocumentsProvider API. For that just simply follow the official Android tutorial for documentproviders: https://developer.android.com/guide/topics/providers/document-provider.html -> open a document, Bitmap section.
Simply I used hcpl's code and extended it: if the file with the retrieved path to the image throws exception I call this function:
private Bitmap getBitmapFromUri(Uri uri) throws IOException {
ParcelFileDescriptor parcelFileDescriptor =
getContentResolver().openFileDescriptor(uri, "r");
FileDescriptor fileDescriptor = parcelFileDescriptor.getFileDescriptor();
Bitmap image = BitmapFactory.decodeFileDescriptor(fileDescriptor);
parcelFileDescriptor.close();
return image;
}
Tested on Nexus 5.
basis with the above code, I reflected the code like below, may be it's more suitable:
public String getPath(Uri uri) {
String selectedImagePath;
//1:MEDIA GALLERY --- query from MediaStore.Images.Media.DATA
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
if(cursor != null){
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
selectedImagePath = cursor.getString(column_index);
}else{
selectedImagePath = null;
}
if(selectedImagePath == null){
//2:OI FILE Manager --- call method: uri.getPath()
selectedImagePath = uri.getPath();
}
return selectedImagePath;
}
I went through the solution from #hcpl & #mad. hcpl's solution supports well for local image in the gallery & mad provided a better solution on top of that - it helps to load OI/Astro/Dropbox image as well. But in my app, while working on picasa library that's now integrated in Android Gallery, both solution fail.
I searched & analyzed a bit & eventually have come with a better & elegant solution that overcomes this limitation. Thanks to Dimitar Darazhanski for his blog, that helped me in this case, I modified a bit to make it easier to understand. Here is my solution goes -
public class BrowsePicture extends Activity {
//YOU CAN EDIT THIS TO WHATEVER YOU WANT
private static final int SELECT_PICTURE = 1;
private String selectedImagePath;
//ADDED
private String filemanagerstring;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
((Button) findViewById(R.id.Button01))
.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
// in onCreate or any event where your want the user to
// select a file
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Select Picture"), SELECT_PICTURE);
}
});
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
Log.d("URI VAL", "selectedImageUri = " + selectedImageUri.toString());
selectedImagePath = getPath(selectedImageUri);
if(selectedImagePath!=null){
// IF LOCAL IMAGE, NO MATTER IF ITS DIRECTLY FROM GALLERY (EXCEPT PICASSA ALBUM),
// OR OI/ASTRO FILE MANAGER. EVEN DROPBOX IS SUPPORTED BY THIS BECAUSE DROPBOX DOWNLOAD THE IMAGE
// IN THIS FORM - file:///storage/emulated/0/Android/data/com.dropbox.android/...
System.out.println("local image");
}
else{
System.out.println("picasa image!");
loadPicasaImageFromGallery(selectedImageUri);
}
}
}
}
// NEW METHOD FOR PICASA IMAGE LOAD
private void loadPicasaImageFromGallery(final Uri uri) {
String[] projection = { MediaColumns.DATA, MediaColumns.DISPLAY_NAME };
Cursor cursor = getContentResolver().query(uri, projection, null, null, null);
if(cursor != null) {
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(MediaColumns.DISPLAY_NAME);
if (columnIndex != -1) {
new Thread(new Runnable() {
// NEW THREAD BECAUSE NETWORK REQUEST WILL BE MADE THAT WILL BE A LONG PROCESS & BLOCK UI
// IF CALLED IN UI THREAD
public void run() {
try {
Bitmap bitmap = android.provider.MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
// THIS IS THE BITMAP IMAGE WE ARE LOOKING FOR.
} catch (Exception ex) {
ex.printStackTrace();
}
}
}).start();
}
}
cursor.close();
}
public String getPath(Uri uri) {
String[] projection = { MediaColumns.DATA};
Cursor cursor = getContentResolver().query(uri, projection, null, null, null);
if(cursor != null) {
//HERE YOU WILL GET A NULLPOINTER IF CURSOR IS NULL
//THIS CAN BE, IF YOU USED OI FILE MANAGER FOR PICKING THE MEDIA
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndexOrThrow(MediaColumns.DATA);
String filePath = cursor.getString(columnIndex);
cursor.close();
return filePath;
}
else
return uri.getPath(); // FOR OI/ASTRO/Dropbox etc
}
Check it & let me know if there's some issue with it. I have tested it & it works well in every case.
Hope this will help everyone.
Assuming you have an image folder in your SD card directory for images only.
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
// tells your intent to get the contents
// opens the URI for your image directory on your sdcard
intent.setType("file:///sdcard/image/*");
startActivityForResult(intent, 1);
Then you can decide with what you would like to do with the content back in your activity.
This was an example to retrieve the path name for the image, test this with your code just to make sure you can handle the results coming back. You can change the code as needed to better fit your needs.
protected final void onActivityResult(final int requestCode, final int
resultCode, final Intent i) {
super.onActivityResult(requestCode, resultCode, i);
// this matches the request code in the above call
if (requestCode == 1) {
Uri _uri = i.getData();
// this will be null if no image was selected...
if (_uri != null) {
// now we get the path to the image file
cursor = getContentResolver().query(_uri, null,
null, null, null);
cursor.moveToFirst();
String imageFilePath = cursor.getString(0);
cursor.close();
}
}
My advice is to try to get retrieving images working correctly, I think the problem is the content of accessing the images on the sdcard. Take a look at Displaying images on sd card.
If you can get that up and running, probably by the example supplying a correct provider, you should be able to figure out a work-around for your code.
Keep me updated by updating this question with your progress. Good luck
this is my revisit to this topic, gathering all the information here, plus from other relevant stack overflow questions. It returns images from some provider, while handling out-of-memory conditions and image rotation. It supports gallery, picasa and file managers, like drop box. Usage is simple: as input, the constructor receives the content resolver and the uri. The output is the final bitmap.
/**
* Creates resized images without exploding memory. Uses the method described in android
* documentation concerning bitmap allocation, which is to subsample the image to a smaller size,
* close to some expected size. This is required because the android standard library is unable to
* create a reduced size image from an image file using memory comparable to the final size (and
* loading a full sized multi-megapixel picture for processing may exceed application memory budget).

How to Select and Crop Image on Android
However, the app will be forced to close sometime, you can fix it by adding android:configChanges attribute into main activity in Manifest file like as:
<activity android:name=".MainActivity"
android:label="#string/app_name" android:configChanges="keyboardHidden|orientation" >
It seems that the camera API lost control with orientation so this will help it. :)
To display images and videos try this:
Intent intent = new Intent();
intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, 1);
startActivityForResult(Intent.createChooser(intent,"Wybierz plik"), SELECT_FILE);
Below solution work for 2.3(Gingerbread)-4.4(Kitkat), 5.0(Lollipop) and 6.0(Marshmallow) also:-
Step 1 Code for opening the gallery to select pics:
public static final int PICK_IMAGE = 1;
private void takePictureFromGalleryOrAnyOtherFolder()
{
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE);
}
Step 2 Code for getting data in onActivityResult:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK) {
if (requestCode == PICK_IMAGE) {
Uri selectedImageUri = data.getData();
String imagePath = getRealPathFromURI(selectedImageUri);
//Now you have imagePath do whatever you want to do now
}//end of inner if
}//end of outer if
}
public String getRealPathFromURI(Uri contentUri) {
//Uri contentUri = Uri.parse(contentURI);
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = null;
try {
if (Build.VERSION.SDK_INT > 19) {
// Will return "image:x*"
String wholeID = DocumentsContract.getDocumentId(contentUri);
// Split at colon, use second item in the array
String id = wholeID.split(":")[1];
// where id is equal to
String sel = MediaStore.Images.Media._ID + "=?";
cursor = context.getContentResolver().query(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
projection, sel, new String[] { id }, null);
} else {
cursor = context.getContentResolver().query(contentUri,
projection, null, null, null);
}
} catch (Exception e) {
e.printStackTrace();
}
String path = null;
try {
int column_index = cursor
.getColumnIndex(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
path = cursor.getString(column_index).toString();
cursor.close();
} catch (NullPointerException e) {
e.printStackTrace();
}
return path;
}
Just in case it helps; I do this to get the Bitmap:
InputStream is = context.getContentResolver().openInputStream(imageUri);
Bitmap bitmap = BitmapFactory.decodeStream(is);
Above Answers are correct. I faced an different issue where in HTC M8 my application crashes when selecting an image from gallery. I'm getting null value for image path. I fixed and optimized with the following solution. in onActivityResult method
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if ((requestCode == RESULT_LOAD_IMAGE) && (resultCode == RESULT_OK)) {
if (data != null) {
Uri selectedImageUri = null;
selectedImageUri = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor imageCursor = mainActivity.getContentResolver().query(
selectedImageUri, filePathColumn, null, null, null);
if (imageCursor == null) {
return;
}
imageCursor.moveToFirst();
int columnIndex = imageCursor.getColumnIndex(filePathColumn[0]);
picturePath = imageCursor.getString(columnIndex);
if (picturePath == null) {
picturePath = selectedImageUri.getPath();
String wholeID = DocumentsContract
.getDocumentId(selectedImage);
// Split at colon, use second item in the array
String id = wholeID.split(":")[1];
String[] column = { MediaStore.Images.Media.DATA };
// where id is equal to
String sel = MediaStore.Images.Media._ID + "=?";
Cursor cursor = mainActivity.getContentResolver().query(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
column, sel, new String[] { id }, null);
columnIndex = cursor.getColumnIndex(column[0]);
if (cursor.moveToFirst()) {
picturePath = cursor.getString(columnIndex);
}
cursor.close();
}
picturePathAbs = new File(picturePath).getAbsolutePath();
imageCursor.close();
}
}

Retrieve a specific type of file
This example will get a copy of the image.
static final int REQUEST_IMAGE_GET = 1;
public void selectImage() {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
if (intent.resolveActivity(getPackageManager()) != null) {

if (requestCode == REQUEST_IMAGE_GET && resultCode == RESULT_OK) {
Bitmap thumbnail = data.getParcelable("data");
Uri fullPhotoUri = data.getData();
// Do work with photo saved at fullPhotoUri
...
}
}
Open a specific type of file
When running on 4.4 or higher, you request to open a file that's managed by another app
static final int REQUEST_IMAGE_OPEN = 1;
public void selectImage() {
Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
intent.setType("image/*");
intent.addCategory(Intent.CATEGORY_OPENABLE);
// Only the system receives the ACTION_OPEN_DOCUMENT, so no need to test.
startActivityForResult(intent, REQUEST_IMAGE_OPEN);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_IMAGE_OPEN && resultCode == RESULT_OK) {
Uri fullPhotoUri = data.getData();
// Do work with full size photo saved at fullPhotoUri
...
}
}
Original source
Additional to previous answers, if you are having problems with getting the right path(like AndroZip) you can use this:
public String getPath(Uri uri ,ContentResolver contentResolver) {
String[] projection = { MediaStore.MediaColumns.DATA};
Cursor cursor;
try{
cursor = contentResolver.query(uri, projection, null, null, null);
} catch (SecurityException e){
String path = uri.getPath();
String result = tryToGetStoragePath(path);
return result;
}
if(cursor != null) {
//HERE YOU WILL GET A NULLPOINTER IF CURSOR IS NULL
//THIS CAN BE, IF YOU USED OI FILE MANAGER FOR PICKING THE MEDIA
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndexOrThrow(MediaStore.MediaColumns.DATA);
String filePath = cursor.getString(columnIndex);
cursor.close();
return filePath;
}
else
return uri.getPath(); // FOR OI/ASTRO/Dropbox etc
}
private String tryToGetStoragePath(String path) {
int actualPathStart = path.indexOf("//storage");
String result = path;
if(actualPathStart!= -1 && actualPathStart< path.length())
result = path.substring(actualPathStart+1 , path.length());
return result;
}

Quickest way to open image from gallery or camera.
Original reference : get image from gallery in android programmatically
Following method will receive image from gallery or camera and will show it in an ImageView. Selected image will be stored internally.

here is my example, might not be as your case exactly.
assuming that you get base64 format from your API provider, give it a file name and file extension, save it to certain location in the file system.

new AsyncTask<String, String, File>() {

intent.setDataAndType(uriImage, "image/*");
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
ctx.startActivity(intent);
}
}.execute(strBase64Image);}
Don't forget to set up a proper file provider at first place in AndroidManifest.xml
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/file_paths"/>
</provider>
where the file path is a xml in .../res/xml/file_path.xml
<?xml version="1.0" encoding="utf-8"?>
<external-files-path name="external_files" path="Accessory"/>
<external-path name="ex_Download" path="Download/" />
<external-path name="ex_Pictures" path="Pictures/" />
<external-files-path name="my_Download" path="Download/" />
<external-files-path name="my_Pictures" path="Pictures/" />
<external-cache-path name="my_cache" path="." />
<files-path name="private_Download" path="Download/" />
<files-path name="private_Pictures" path="Pictures/" />
<cache-path name="private_cache" path="." />
Long story short, have file provider ready at first, pass Uri to Intent for known and accessible picture source, otherwise, save the picture in desired location and then pass the location (as Uri) to Intent.

I want to get an image from the gallery and store it to internal storage but in this code, it is only saving the name of the file in the directory. If someone could help me to solve this.
You could use FileOutputStream to store your bitmap. After getting the bitmap from gallery, FileOutputStream out = null;
try {
out = new FileOutputStream("fileName"); //Enter the desired filename
bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (out != null) {
out.close();
}
} catch (Exception e) {
e.printStackTrace();
}
}
you are writing Image file on external storage
File filepath = Environment.getExternalStorageDirectory();
so check that you have mention proper permission in android manifest to write data on SD card
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
and also get the bitmap from selected path
Bitmap bitmap = BitmapFactory.decodeFile(picturePath);
instead of
bitmap = BitmapFactory.decodeResource(getResources(),
RESULT_LOAD_IMAGE);
RESULT_LOAD_IMAGE is request code not resource id of selected image
OnChoose Code
chooseimage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {

So basically what i am trying to achieve is opening the Gallery in Android and let the user select multiple images. Now this question has been asked frequently but i'm not satisfied with the answers. Mainly because i found something interesting in de docs in my IDE (i come back on this later) and thereby i don't want to use a custom adapter but just the vanilla one.
Now my code for selecting one image is:
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Picture"), 1);
Now People on SO and other websites wil tell you you have 2 options:
1) Do not use ACTION_GET_CONTENT but ACTION_SEND_MULTIPLE instead.
This one doesn't work. This one is according to the docs for sending files and not retrieving and that's exactly what it does. When using ACTION_SEND_MULTIPLE i got a window opened at my device where i have to select an application to send my data to. That's not what i want, so i wonder how people got this achieved with this solution.. Do i miss something?
2) Implement an custom Gallery. Now this is my last option i will consider because imho it's not what i am searching for because i have to style it myself AND why the heck you just can't select multiple images in the vanilla gallery?
There must be an option for this.. Now the interesting thing what i'v found is this:
I found this in the docs description of ACTION_GET_CONTENT.
If the caller can handle multiple returned items (the user performing
multiple selection), then it can specify EXTRA_ALLOW_MULTIPLE to
indicate this.
This is pretty interesting. Here they are referring it to the use case where a user can select multiple items?
Later on they say in the docs:
You may use EXTRA_ALLOW_MULTIPLE to allow the user to select multiple
items.
So this is pretty obvious right? This is what i need. But my following question is: Where can i put this EXTRA_ALLOW_MULTIPLE? The sad thing is that i can't find this no where in the developers.android guide and also is this not defined as a constant in the INTENT class.
Anybody can help me out with this EXTRA_ALLOW_MULTIPLE?
The EXTRA_ALLOW_MULTIPLE option is set on the intent through the Intent.putExtra() method:
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
Your code above should look like this:
Intent intent = new Intent();
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Picture"), 1);
Note: the EXTRA_ALLOW_MULTIPLE option is only available in Android API 18 and higher.
Define these variables in the class:
int PICK_IMAGE_MULTIPLE = 1;
String imageEncoded;
List<String> imagesEncodedList;
Let's Assume that onClick on a button it should open gallery to select images
Intent intent = new Intent();
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Picture"), PICK_IMAGE_MULTIPLE);
Then you should override onActivityResult Method
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
try {
// When an Image is picked
if (requestCode == PICK_IMAGE_MULTIPLE && resultCode == RESULT_OK
&& null != data) {
// Get the Image from data
String[] filePathColumn = { MediaStore.Images.Media.DATA };
imagesEncodedList = new ArrayList<String>();
if(data.getData()!=null){
Uri mImageUri=data.getData();
// Get the cursor
Cursor cursor = getContentResolver().query(mImageUri,
filePathColumn, null, null, null);
// Move to first row
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
imageEncoded = cursor.getString(columnIndex);
cursor.close();
} else {
if (data.getClipData() != null) {
ClipData mClipData = data.getClipData();
ArrayList<Uri> mArrayUri = new ArrayList<Uri>();
for (int i = 0; i < mClipData.getItemCount(); i++) {
ClipData.Item item = mClipData.getItemAt(i);
Uri uri = item.getUri();
mArrayUri.add(uri);
// Get the cursor
Cursor cursor = getContentResolver().query(uri, filePathColumn, null, null, null);
// Move to first row
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
imageEncoded = cursor.getString(columnIndex);
imagesEncodedList.add(imageEncoded);
cursor.close();
}
Log.v("LOG_TAG", "Selected Images" + mArrayUri.size());
}
}
} else {
Toast.makeText(this, "You haven't picked Image",
Toast.LENGTH_LONG).show();
}
} catch (Exception e) {
Toast.makeText(this, "Something went wrong", Toast.LENGTH_LONG)
.show();
}
super.onActivityResult(requestCode, resultCode, data);
}
NOTE THAT:
the gallery doesn't give you the ability to select multi-images so we here open all images studio that you can select multi-images from them.
and don't forget to add the permissions to your manifest
VERY IMPORTANT:
getData(); to get one single image and I've stored it here in imageEncoded String
if the user select multi-images then
they should be stored in the list
So you have to check which is null to use the other
Wish you have a nice try and to others
A lot of these answers have similarities but are all missing the most important part which is in onActivityResult, check if data.getClipData is null before checking data.getData
The code to call the file chooser:
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*"); //allows any image file type. Change * to specific extension to limit it
//**The following line is the important one!
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), SELECT_PICTURES); //SELECT_PICTURES is simply a global int used to check the calling intent in onActivityResult
The code to get all of the images selected:
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == SELECT_PICTURES) {
if(resultCode == Activity.RESULT_OK) {
if(data.getClipData() != null) {
int count = data.getClipData().getItemCount(); //evaluate the count before the for loop --- otherwise, the count is evaluated every loop.
for(int i = 0; i < count; i++) {
Uri imageUri = data.getClipData().getItemAt(i).getUri();
//do something with the image (save it to some directory or whatever you need to do with it here)
}
}
} else if(data.getData() != null) {
String imagePath = data.getData().getPath();
//do something with the image (save it to some directory or whatever you need to do with it here)
}
}
}
Note that Android's chooser has Photos and Gallery available on some devices. Photos allows multiple images to be selected. Gallery allows just one at a time.
I hope this answer isn't late. Because the gallery widget doesn't support multiple selection by default, but you can custom the gridview which accepted your multiselect intent. The other option is to extend the gallery view and add in your own code to allow multiple selection.
This is the simple library can do it: https://github.com/luminousman/MultipleImagePick
Update:
From #ilsy's comment, CustomGalleryActivity in this library use manageQuery, which is deprecated, so it should be changed to getContentResolver().query() and cursor.close() like this answer
Initialize instance:
private String imagePath;
private List<String> imagePathList;
In onActivityResult You have to write this, If-else 2 block. One for single image and another for multiple image.
if (requestCode == GALLERY_CODE && resultCode == RESULT_OK && data != null) {
imagePathList = new ArrayList<>();
if (data.getClipData() != null) {
int count = data.getClipData().getItemCount();
for (int i=0; i<count; i++) {
Uri imageUri = data.getClipData().getItemAt(i).getUri();
getImageFilePath(imageUri);
}
}
else if (data.getData() != null) {
Uri imgUri = data.getData();
getImageFilePath(imgUri);
}
}
Most important part, Get Image Path from uri:
public void getImageFilePath(Uri uri) {
File file = new File(uri.getPath());
String[] filePath = file.getPath().split(":");
String image_id = filePath[filePath.length - 1];
Cursor cursor = getContentResolver().query(android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI, null, MediaStore.Images.Media._ID + " = ? ", new String[]{image_id}, null);
if (cursor!=null) {
cursor.moveToFirst();
imagePath = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
imagePathList.add(imagePath);
cursor.close();
}
}
Hope this can help you.
2022 - The Android Jetpack Compose way
For selecting multiple images in the gallery with Android Jetpack Compose.
val launcherMultipleImages = rememberLauncherForActivityResult(
contract = ActivityResultContracts.GetMultipleContents(),
) { uriList: List<Uri> ->
// TODO
}
And then use launcherMultipleImages.launch("image/*") to start the images selection.
For example :
Button(onClick = { launcherMultipleImages.launch("image/*") }) {
Text(text = "Select images")
}
this works for multiple image selection. also tested in API 29,30 in Google photos.
private static final int PICK_IMAGE = 2;
Intent intent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
startActivityForResult(Intent.createChooser(intent, "Select
images"),PICK_IMAGE);
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_IMAGE && resultCode == RESULT_OK) {
if(data.getClipData() != null) {
int count = data.getClipData().getItemCount();
for(int i = 0; i < count; i++) {
Uri imageUri = data.getClipData().getItemAt(i).getUri();
//do what do you want to do
}
}
else if(data.getData() != null) {
Uri selectedImageUri = data.getData();
//do what do you want to do
}
}
Define getContent as below;
val getContent =
registerForActivityResult(ActivityResultContracts.GetMultipleContents())
{ uriList ->
// todo
}
after you grant related permission run the below code
getContent.launch("images/*")
I got null from the Cursor.
Then found a solution to convert the Uri into Bitmap that works perfectly.
Here is the solution that works for me:
#Override
public void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
{
if (resultCode == Activity.RESULT_OK) {
if (requestCode == YOUR_REQUEST_CODE) {
if (data != null) {
if (data.getData() != null) {
Uri contentURI = data.getData();
ex_one.setImageURI(contentURI);
Log.d(TAG, "onActivityResult: " + contentURI.toString());
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(context.getContentResolver(), contentURI);
} catch (IOException e) {
e.printStackTrace();
}
} else {
if (data.getClipData() != null) {
ClipData mClipData = data.getClipData();
ArrayList<Uri> mArrayUri = new ArrayList<Uri>();
for (int i = 0; i < mClipData.getItemCount(); i++) {
ClipData.Item item = mClipData.getItemAt(i);
Uri uri = item.getUri();
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(context.getContentResolver(), uri);
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
}
}
}
}
Hi below code is working fine.
Cursor imagecursor1 = managedQuery(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, columns, null,
null, orderBy + " DESC");
this.imageUrls = new ArrayList<String>();
imageUrls.size();
for (int i = 0; i < imagecursor1.getCount(); i++) {
imagecursor1.moveToPosition(i);
int dataColumnIndex = imagecursor1
.getColumnIndex(MediaStore.Images.Media.DATA);
imageUrls.add(imagecursor1.getString(dataColumnIndex));
}
options = new DisplayImageOptions.Builder()
.showStubImage(R.drawable.stub_image)
.showImageForEmptyUri(R.drawable.image_for_empty_url)
.cacheInMemory().cacheOnDisc().build();
imageAdapter = new ImageAdapter(this, imageUrls);
gridView = (GridView) findViewById(R.id.PhoneImageGrid);
gridView.setAdapter(imageAdapter);

I also had the same issue. I also wanted so users could take photos easily while picking photos from the gallery. Couldn't find a native way of doing this therefore I decided to make an opensource project. It is much like MultipleImagePick but just better way of implementing it.
https://github.com/giljulio/android-multiple-image-picker
private static final RESULT_CODE_PICKER_IMAGES = 9000;
Intent intent = new Intent(this, SmartImagePicker.class);
startActivityForResult(intent, RESULT_CODE_PICKER_IMAGES);
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode){
case RESULT_CODE_PICKER_IMAGES:
if(resultCode == Activity.RESULT_OK){
Parcelable[] parcelableUris = data.getParcelableArrayExtra(ImagePickerActivity.TAG_IMAGE_URI);
//Java doesn't allow array casting, this is a little hack
Uri[] uris = new Uri[parcelableUris.length];
System.arraycopy(parcelableUris, 0, uris, 0, parcelableUris.length);
//Do something with the uris array
}
break;
default:
super.onActivityResult(requestCode, resultCode, data);
break;
}
}
Try this one IntentChooser. Just add some lines of code, I did the rest for you.
private void startImageChooserActivity() {
Intent intent = ImageChooserMaker.newChooser(MainActivity.this)
.add(new ImageChooser(true))
.create("Select Image");
startActivityForResult(intent, REQUEST_IMAGE_CHOOSER);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_IMAGE_CHOOSER && resultCode == RESULT_OK) {
List<Uri> imageUris = ImageChooserMaker.getPickMultipleImageResultUris(this, data);
}
}
PS: as mentioned at the answers above, EXTRA_ALLOW_MULTIPLE is only available for API >= 18. And some gallery apps don't make this feature available (Google Photos and Documents (com.android.documentsui) work.

For Multiple image selection and with selection limit restriction feature, use chintan369/MultiImagePicker library which is the latest of 2021 and supports Android 11 too. It is well documented and also demo is explained on youtube for use. It's very easy to add in the project, easy to use to call the library for image selection and getting results of selected images as Uri list and also you can request result list as absolute file path list.
When I pick an image from my gallery, screenshots are shown but some images taken from camera aren't shown.
To be more specific, images taken using the system Camera app can't be shown while the ones taken using Camera360 can.
I wonder if there's any problem with my code. If there isn't, maybe it's because of my phone?
Thanks in advance. Sorry, my English isn't very good.

Ok, so I have looked through various answers on this site and in practice they all seem great and pretty much the standard way of doing this. Well, standard has failed me. So, I want to have an ImageButton access the gallery and have the user select an image. After the user selects that image I want it to become the ImageButton's background. My code so far is:

import android.app.Activity;

private String selectedImagePath;
private ImageButton wrestlerPicture;
#Override
protected void onCreate(Bundle newWrestler) {
super.onCreate(newWrestler);
setContentView(R.layout.new_wrestler);
wrestlerPicture = (ImageButton) findViewById(R.id.wrestlerPhoto);
wrestlerPicture.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
startActivityForResult(new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI), 1);
}
});
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == 1) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
System.out.println("Image Path : " + selectedImagePath);
wrestlerPicture.setImageURI(selectedImageUri);
}
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
#Override

// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
Please help me It is really getting on my nerves now haha...
(1) Don't say "It is really getting on my nerves" and then "haha..." It makes me think you've got a plastered smile on your face, and a knife behind your back.
(2) cursor.moveToFirst() returns a boolean, so:
if(cursor.moveToFirst())
Log.d("CURSOR STATUS: ", "SUCCESSFULLY MOVED TO FIRST");
else
Log.d("CURSOR STATUS: ", "FAILED TO MOVE TO FIRST :'(");
(3) What's this printing?
System.out.println("Image Path : " + selectedImagePath);
If it's printing the actual uri path, that helps a LOT. But you should use Logcat, not System.
(4) I do something like this in my own app, but I'm changing an imageview. Maybe the code will be of use:
Uri selectedImageUri = data.getData();
//In the following code, I'm trying to get
//the path for the image file
try {
imageBMP = null;
String selectedImagePath = getPath(selectedImageUri);
if (selectedImagePath != null) {
filePath = selectedImagePath;
//Potentially long-running tasks must be put on their own

Should work for you. You'd probably be better using asynctasks than the threads I used, but it's easier to read this way.
Use this code.
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case 1:
{
if (resultCode == RESULT_OK)
{
if(requestCode == 1)
{
Uri photoUri = data.getData();
if (photoUri != null)
{
try {
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(photoUri, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String filePath = cursor.getString(columnIndex);
cursor.close();
bMap_image = BitmapFactory.decodeFile(filePath);
wrestlerPicture.setImageResource.setImageBitmap(bMap_image);
}catch(Exception e)
{}
}
}
}
}
}
I want to use intent to open camera in Android .
I used the following code but when i press the button (whose action is onclick() function the app closes on itself .
public void onclick(int actionCode){
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(takePictureIntent, actionCode);
}
public static boolean isIntentAvailable(Context context, String action) {
final PackageManager packageManager = context.getPackageManager();
final Intent intent = new Intent(action);
List<ResolveInfo> list = packageManager.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
return list.size() > 0;
}
If someone can help me .
File destination;

public static String selectedPath1 = "NONE";
private static final int PICK_Camera_IMAGE = 2;
private static final int SELECT_FILE1 = 1;
public static Bitmap bmpScale;

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

Uri.fromFile(destination));
startActivityForResult(intent, PICK_Camera_IMAGE);

break;
}
}
try this code
public static final int CAMERA_PIC_REQUEST = 1;//firstly define this
Intent photo= new Intent("android.media.action.IMAGE_CAPTURE");
startActivityForResult(photo, CAMERA_PIC_REQUEST);
The parameter passed to an "on-click" method is of type View not int as you show.
According to this tutorial your onClick method should be as follows:
public void onclick( View v ){
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(takePictureIntent, CAMERA_PIC_REQUEST);
}
Where CAMERA_PIC_REQUEST is defined as (although I'm not quite sure why you would need to statically hard-code this value in your application):
private static final int CAMERA_PIC_REQUEST = 1337;
Update
CAMERA_PIC_REQUEST is used to uniquely identify the result being returned to onActivityResult. Multiple startActivityForResultrequests could be outstanding at one time.
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_PIC_REQUEST) {
if (resultCode == RESULT_OK) {
tv.setText("Got picture!");
imageData = (Bitmap) data.getExtras().get("data");
ImageView image = (ImageView) findViewById(R.id.imageView1);
image.setImageBitmap(imageData);
} else if (resultCode == RESULT_CANCELED){
tv.setText("Cancelled");
}
}
}
please have a look at this code, this is working fine with me
//define the file-name to save photo taken by Camera activity
fileName = "new-photo-name.jpg";
//create parameters for Intent with filename
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE, fileName);
values.put(MediaStore.Images.Media.DESCRIPTION,"Image capture by camera");
imageUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
also apply this method to read image when you taken the image from camera.
//handling intent responses
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == Activity.RESULT_OK)
try {
if (bitmap != null) {bitmap.recycle();}
String[] proj = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(imageUri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
imageUriString = cursor.getString(column_index);
getContentResolver().notifyChange(imageUri, null);
ContentResolver cr = getContentResolver();
try {
bitmap = android.provider.MediaStore.Images.Media.getBitmap(cr, imageUri);
imageButtonPictureShop.setImageBitmap(bitmap);
// this.uploadImage();
this.executeMultipartPost();
// this.uploadFile(imageUriString);
}
catch (Exception e)
{
Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT).show();
if(e.getMessage() != null)Log.e("Exception" , e.getMessage());
else Log.e("Exception" , "Exception");
e.printStackTrace();
}
}
catch (Exception e)
{
if(e.getMessage() != null)Log.e("Exception" , e.getMessage());
else Log.e("Exception" , "Exception");
e.printStackTrace();
}
super.onActivityResult(requestCode, resultCode, data);
}
I know this question old and answered, but for those who are asking how to get the image file ?
heres the solution.
String ExternalStorageDirectoryPath = Environment.getExternalStorageDirectory().getAbsolutePath();
String targetPath = ExternalStorageDirectoryPath + "/DCIM/Camera";
File targetDirector = new File(targetPath);
File[] files = targetDirector.listFiles()
String ImagePath = files[ file.files-1 ].getAbsolutePath();
Bitmap bmp = BitmapFactory.decodeFile(pathName);
ivImage.setImageBitmap( bmp );
Also you don't need to add Camera permissions on your Manifest file.
-Cheers and vote up if this help you
-Happy Codings..
It's very easy to start camera from your Android app:
just write two lines code in onClick method
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, CAMERA_PIC_REQUEST );
Add one constant field in your class (you can use any random number instead of 7)
private int CAMERA_PIC_REQUEST = 7;
After a lot of research I found this solution. Just to make things clear I created an entire app for this question which serves the purpose of opening the camera clicking a photo and setting the image as the ImageBitmap of an ImageView. The code asked in this question starts at the second block i.e. the setView() method which is below the onCreate() method following which we have the onActivityResult() method
Here is a demo of the app.
Below I have Attached the MainActivity.java file
package com.cr7.opencamera;
import android.Manifest;
import android.app.Activity;
import android.content.ContentResolver;
import android.content.ContentValues;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.graphics.Bitmap;
import android.net.Uri;
import android.os.Bundle;
import android.provider.MediaStore;
import android.util.Log;
import android.widget.Button;
import android.widget.ImageView;
import androidx.annotation.NonNull;
import androidx.annotation.Nullable;
import androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.ActivityCompat;
import androidx.core.content.ContextCompat;
import java.io.IOException;
public class MainActivity extends AppCompatActivity {
private Button buttonCaptureImageFromCamera;
private Uri imageUri;
private ImageView imageViewCameraImage;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Button that will open the camera
buttonCaptureImageFromCamera = findViewById(R.id.buttonCaptureImageFromCamera);
// ImageView that will store the image
imageViewCameraImage = findViewById(R.id.imageViewCameraImage);
askPermission();
}
Here imageUri is a global variable so that it can be used in the onActivityResult() method
// Sets OnClickListener for the button if storage permission is given
private void setView() {
buttonCaptureImageFromCamera.setOnClickListener(v -> {
String fileName = "new-photo-name.jpg";
// Create parameters for Intent with filename
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE, fileName);
values.put(MediaStore.Images.Media.DESCRIPTION, "Image capture by camera");
imageUri =
getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
values);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(intent, 1231);
});
}
This is the onActivityResult method. Here I've used imageUri i.e. the global variable of type Uri which was initialized in the OnClickListener of the button in the setView() method above.
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1231 && resultCode == Activity.RESULT_OK) {
try {
ContentResolver cr = getContentResolver();
try {
// Creating a Bitmap with the image Captured
Bitmap bitmap = MediaStore.Images.Media.getBitmap(cr, imageUri);
// Setting the bitmap as the image of the
imageViewCameraImage.setImageBitmap(bitmap);
} catch (IOException e) {
e.printStackTrace();
}
} catch (IllegalArgumentException e) {
if (e.getMessage() != null)
Log.e("Exception", e.getMessage());
else
Log.e("Exception", "Exception");
e.printStackTrace();
}
}
}
Remaining code...
// Asking user for storage permission
public void askPermission() {
// Checking if the permissions are not granted.
if (
ContextCompat.checkSelfPermission(
this,
android.Manifest.permission.WRITE_EXTERNAL_STORAGE
) != PackageManager.PERMISSION_GRANTED ||
ContextCompat.checkSelfPermission(
this,
android.Manifest.permission.READ_EXTERNAL_STORAGE
) != PackageManager.PERMISSION_GRANTED
) {
// If not granted requesting Read and Write storage
ActivityCompat.requestPermissions(this, /*You can ask for multiple request by adding
more permissions to the string*/new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE,
Manifest.permission.READ_EXTERNAL_STORAGE}, 60);
} else {
// If permissions are granted we proceed by setting an OnClickListener for the button
// which helps the user pick the image
setView();
}
}
// This method is called after the permissions have been asked i.e. the dialog that says
// allow or deny
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions,
#NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
// Now by default we assume that the permission has not been granted
boolean allPermissionsGranted = false;
// Now we check if the permission was granted
if ( requestCode == 60 && grantResults.length > 0) {
// If all the permissions are granted allPermissionsGranted is set to true else false
allPermissionsGranted = grantResults[0] == PackageManager.PERMISSION_GRANTED
&&
grantResults[1] == PackageManager.PERMISSION_GRANTED;
}
// If permissions are granted we call the setView Method which prompts the user to pick
// an Image either by the clicking it now or picking from the gallery
if ( allPermissionsGranted ) {
setView();
}
}
}
These blocks of code are in sequence i.e. if you merge all these blocks you get the complete MainActivity.java class.
If you wan to Implement this app you need yo create a layout file with an ImageView with an id "imageViewCameraImage"and a button with an id "buttonCaptureImageFromCamera".
Hope this helps. I know this is long and I'm making it longer by writing this.
Regards,
Joel
