I need to take a photo from my app and display it on an imageView, so now I´m using an intent request:
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, REQUEST_CAMERA);
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == REQUEST_CAMERA) {
bm = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(bm);
}
}
}
The problem is that this code gets the thumbail of the image, not the image itself in full resollution, and I don´t know how to get it. I´ve searched and I have found this https://developer.android.com/training/camera/photobasics.html , but as I´m starting with this i don´t understand it.
Could somebody help me please?
Before you call CameraIntent create a file and uri based on that filepath as shown here.
filename = Environment.getExternalStorageDirectory().getPath() + "/test/testfile.jpg";
imageUri = Uri.fromFile(new File(filename));
// start default camera
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT,
imageUri);
startActivityForResult (cameraIntent, CAMERA_PIC_REQUEST);
Now, you have the filepath you can use it in onAcityvityResult method as following,
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode != CAMERA_PIC_REQUEST || filename == null)
return;
ImageView img = (ImageView) findViewById(R.id.image);
img.setImageURI(imageUri);
Try out this code, It works for me.
Open camera using below code:
Intent intent = new Intent();
try {
if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)&& !Environment.getExternalStorageState().equals(
Environment.MEDIA_MOUNTED_READ_ONLY)) {
intent.setAction(MediaStore.ACTION_IMAGE_CAPTURE);
File file = new File(Uri.parse(Environment.getExternalStorageDirectory().getAbsolutePath()+ File.separator+ ".your folder name"
+ File.separator + "picture").getPath());
if (!file.exists()) {
file.mkdirs();
}
capturedImageUri = Uri.fromFile(File.createTempFile("your folder name" + new SimpleDateFormat("ddMMyyHHmmss", Locale.US).format(new Date()), ".jpg", file));
intent.putExtra(MediaStore.EXTRA_OUTPUT, capturedImageUri);
startActivityForResult(intent, Util.REQUEST_CAMERA);
} else {
Toast.show(getActivity(),"Please insert memory card to take pictures and make sure it is write able");
}
} catch (Exception e) {
e.printStackTrace();
}
In onActivityResult retrieve path of captured image:
try {
if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED) && !Environment.getExternalStorageState().equals(
Environment.MEDIA_MOUNTED_READ_ONLY)) {
File file = new File(Uri.parse(Environment.getExternalStorageDirectory().getAbsolutePath()+ File.separator
+ ".captured_Images"+ File.separator+ "picture").getPath());
if (!file.exists()) {
file.mkdirs();
}
selectedPath1 = capturedImageUri.toString().replace("file://", "");
Logg.e("selectedPath1", "OnactivityResult==>>" + selectedPath1);
imageLoader.displayImage(capturedImageUri.toString(), imgCarDetails1);
} else {
Toast.show(getActivity(), "Please insert memory card to take pictures and make sure it is write able");
}
} catch (Exception e) {
e.printStackTrace();
}
Add this permission in Manifest file:-
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
#SuppressWarnings("deprecation")
Cursor cursor = getActivity().managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
None of the answers worked for me, and I couldn´t use the tutorial as when creating the FileProvider, the xml gives me an error.
Finally I found this answer which works like a charm. Android Camera Intent: how to get full sized photo?

In my application ,on clicking Image View i want to start Camera which will capture image and display it in another image view.My code is given below:
//On clicking Camera

My problem is that ,on some mobiles it is working fine but on some it is not. For example: If i am testing my application using on my phone Yu Yureka having Lollipop ,it is giving me data as null.Also when the orientation changes,application is crashing .Please help me to fix the issue.
In your Manifest file use these permission
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
Implement from this Simple Code Example this is my working example code
public void CameraClick(View v) {
Intent intent= new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// creating Dir to save clicked Photo
String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/cam_Intent");
myDir.mkdirs();
// save clicked pic to given dir with given name
File file = new File(Environment.getExternalStorageDirectory(),
"/cam_Intent/MyPhoto.jpg");
outPutfileUri = Uri.fromFile(file);
intent.putExtra(MediaStore.EXTRA_OUTPUT, outPutfileUri);
startActivityForResult(intent, TAKE_PIC);
}
Bitmap bitmap = null;
#Override
protected void onActivityResult(int requestCode, int resultCode,Intent data)
{
if (requestCode == TAKE_PIC && resultCode==RESULT_OK) {
String uri = outPutfileUri.toString();
Log.e("uri-:", uri);
Toast.makeText(this, outPutfileUri.toString(),Toast.LENGTH_LONG).show();
//Bitmap myBitmap = BitmapFactory.decodeFile(uri);
// mImageView.setImageURI(Uri.parse(uri)); OR drawable make image strechable so try bleow also
try {
bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), outPutfileUri);
Drawable d = new BitmapDrawable(getResources(), bitmap);
mImageView.setImageDrawable(d);
} catch (IOException e) {
e.printStackTrace();
}
}
}
I'm working on an app that uses the camera and saves the pictures to DCIM/MyAppFolder. My first question is should I be saving it to DCIM or Pictures? If it even matters. My second question is I noticed it takes a while for the folder/pictures to show up in the native gallery app. After testing this with other apps (Instagram, Snapseed, ect) those photos show up immediately. Is there a piece of code I'm missing to accomplish this? My code is as followed:
public void takePhoto() {
Intent imageIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
//folder stuff
File imagesFolder = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM), "MyAppFolder");
imagesFolder.mkdirs();
//String filePath = "/MyImages/QR_" + timeStamp + ".png" ;
File image = new File(imagesFolder, "IMG_" + timeStamp + ".jpg");
imageUri = Uri.fromFile(image);
imageIntent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(imageIntent, TAKE_PICTURE);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case 1:
if (resultCode == Activity.RESULT_OK) {
Uri selectedImage = imageUri;
getContentResolver().notifyChange(selectedImage, null);
ContentResolver cr = getContentResolver();
Bitmap bitmap;
try {
bitmap = android.provider.MediaStore.Images.Media
.getBitmap(cr, selectedImage);
Toast.makeText(this, selectedImage.toString(),
Toast.LENGTH_LONG).show();
} catch (Exception e) {
Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT)
.show();
Log.e("Camera", e.toString());
}
}
}
}
to update the gallery app. simply after you click save just put this simple code after saving.
sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED,
Uri.parse("file://"
+ Environment.getExternalStorageDirectory())));
this code will tell the gallery app that something has been added so please rescan for media now :D.
I'm trying to display the path of a saved picture taken by the camera, by calling
`data.getdata`
inside a Toast, but the App crashs. I also tried data.getDataString but it did not solve
any thing.
Code:
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent imageIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File imagesFolder = new File(Environment.getExternalStorageDirectory(), "My Images");
imagesFolder.mkdirs();
File image = new File(imagesFolder, "img01");
Uri uriSavedImage = Uri.fromFile(image);
imageIntent.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
startActivityForResult(imageIntent,CAMERA_REQUEST_CODE);
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if ((requestCode == CAMERA_REQUEST_CODE) && (resultCode == RESULT_OK)) {
Toast.makeText(getApplicationContext(), "Image Saved To: "+data.getData(), Toast.LENGTH_SHORT).show();
}
Camera Intent result woes
looked through this..
have you tried data.getExtras().get(TAG); ?
Get the extras bundle from your intent, there is the resulting data accessible.
Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
Don't forget a null check, since I'm in the impression that the tag "data" is not valid on all phones.
edit: Made code more precise, i.e. giving the exact solution here.
Also use, data.getData().toString()
data.getData().toString() should work. But, it won't actually give you the actual path of the image stored. It'll rather give you an URI of that image. You'll need to parse that uri using.
public String getRealPathFromURI(String uriString) {
try {
String[] proj = { MediaStore.Image.Media.DATA};
Log.d("First", proj[0]);
Cursor cursor = managedQuery(Uri.parse(uriString), proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Image.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return "Alas!";
}
I am using this code to fetch Image from gallery:
fromGalleryButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
canvasPictureDialog.dismiss();
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);//
//startActivity(intent);
startActivityForResult(Intent.createChooser(intent, "Select Picture"),10);
//finish();
}
});
And to take image from camera i use this code:
private static final int TAKE_PHOTO_CODE = 1;
private void takePhoto(){
final Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(getTempFile(this)) );
startActivityForResult(intent, TAKE_PHOTO_CODE);
}
private File getTempFile(Context context){
//it will return /sdcard/image.tmp
//final File path = new File( Environment.getExternalStorageDirectory(), context.getPackageName() );
final File path = new File( Environment.getExternalStorageDirectory(), context.getPackageName());
if(!path.exists()){
path.mkdir();
}
return new File(path, "image.tmp");
}
And common code for onActivityResult is:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 10 && resultCode == Activity.RESULT_OK) {
Uri contentUri = data.getData();
String[] proj = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(contentUri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
imagePath = cursor.getString(column_index);
//Bitmap croppedImage = BitmapFactory.decodeFile(imagePath);
tempBitmap = BitmapFactory.decodeFile(imagePath);
photoBitmap = Bitmap.createScaledBitmap(tempBitmap, display.getWidth(), display.getHeight(), true);
}
if(resultCode == RESULT_OK && requestCode==TAKE_PHOTO_CODE){
final File file = getTempFile(this);
try {
tempBitmap = Media.getBitmap(getContentResolver(), Uri.fromFile(file) );
photoBitmap = Bitmap.createScaledBitmap(tempBitmap, display.getWidth(), display.getHeight(), true);
// do whatever you want with the bitmap (Resize, Rename, Add To Gallery, etc)
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
Now with using this code i am drawing the image on canvas:
if(!(imagePath==null))
{
//tempBitmap = BitmapFactory.decodeFile(imagePath);
//photoBitmap = Bitmap.createScaledBitmap(tempBitmap, display.getWidth(), display.getHeight(), true);
canvas.drawBitmap (photoBitmap,0, 0, null);
}
But with that use, I am able to get Image from gallery but not from the camera. Why ??
Whats wrong in my code ??
Thanks.
Well, I have solve this problem for my own way.
There is a logical mistake. I have taken the if condition on imagePath variable which can not works for the taking image from camera.
I have taken one boolean Variable and set it for Taking Image from Camera and it works for me.
Anyway, Thanks for the Comments and help.
Thanks.
I new in the android developing.
I want to develop simple application that will be able to take a picture using the cell phone camara and show it on the screen of the cell phone.
Is there some simple example that i can use ? or some code that can help me learn how to do it ?
Thanks for any help
to start camera you use
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, 0);
and here you have the handeling
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 0) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo);
}
}
Try this.. Use the below code in onCreate
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
URI mUri = Uri.fromFile(new File(Environment.getExternalStorageDirectory(),
"pic_" + String.valueOf(System.currentTimeMillis()) + ".jpg"));
intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, mUri);
try {
intent.putExtra("return-data", true);
startActivityForResult(intent, CAMERA_RESULT);
} catch (ActivityNotFoundException e) {
e.printStackTrace();
}
Then OnActivityResult
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
//Here you will get path of image stored in sdcard then pass it to next activity as your desires..
mImagePath = extras.getString("image-path");
mSaveUri = getImageUri(mImagePath);
Bitmap mBitmap = getBitmap(mImagePath);
// here mBitmap is assigned to any imageview and you can use it in for display
}
}
private Uri getImageUri(String path) {
return Uri.fromFile(new File(path));
}
private Bitmap getBitmap(String path) {
Uri uri = getImageUri(path);
InputStream in = null;
try {
in = mContentResolver.openInputStream(uri);
return BitmapFactory.decodeStream(in).copy(Config.ARGB_8888, true);
} catch (FileNotFoundException e) {
//Log.e(TAG, "file " + path + " not found");
}
return null;
}
}
