I'm trying to get a picture from user during a registration proccess. So I have a form, and a button that starts camera, galerry, dropbox etc and asks user to choose or take a pic.
At the button onClick method I'm using the example at the 2nd answer of this topic Allow user to select camera or gallery for image and it opens a dialog with my image apps as options. After taking or choosing a foto, my code at onActivityResult is the following:
Bundle extras = data.getExtras();
Bitmap mImageBitmap = (Bitmap) extras.get("data");
foto.setImageBitmap(mImageBitmap)
So I have 2 problems. First, this get only a thumbnail image, and not the full-sized picture I need. Second, this only works if user chooses to take a new pic with camera...
for getting the fullsize pic, this code seems good Android Camera Intent: how to get full sized photo? but its only for camera-taken pics, and also with this chooser intent I'm not sure where this code would fit. Should I verify witch source use has choosed? If so, how could I do that?
EDIT: The chooser intent offers me 4 options of image sources: Camera, Gallery, Dropbox and ASTRO File Manager. Of course more options would be available if I had other apps installed. So I've checked the intent contents at each case:
CAMERA: act=inline-data (has extras)
DROPBOX and GALLERY: dat="file path"
ASTRO: dat="file path" (has extras)
so verifying if the intent has extras or not doesn't tells me the source. Also both
data.hasExtra("act") and
data.hasExtra("dat")
are returning false.
Here is the code for getting the full size image from camera captured image
declare object
private File dir, destImage,f;
private String cameraFile = null;
private static final int CAPTURE_FROM_CAMERA = 1;
in your activity
dir = new File(Environment.getExternalStorageDirectory()
.getAbsolutePath(), "MyApp");
if (!dir.isDirectory())
dir.mkdir();
destImage = new File(dir, new Date().getTime() + ".jpg");
cameraFile = destImage.getAbsolutePath();
try{
if(!destImage.createNewFile())
Log.e("check", "unable to create empty file");
}catch(IOException ex){
ex.printStackTrace();
}
f = new File(destImage.getAbsolutePath());
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
i.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(destImage));
startActivityForResult(i,CAPTURE_FROM_CAMERA);
in your onActivityResult
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case CAPTURE_FROM_CAMERA:
if (resultCode==RESULT_OK) {
if(f==null){
if(cameraFile!=null)
f = new File(cameraFile);
else
Log.e("check", "camera file object null line no 279");
}else
Log.e("check", f.getAbsolutePath());
Bitmap useBitmap = BitmapFactory.decodeFile(f.getAbsolutePath());
// now use this bitmap wherever you want
}
break;
}
}

In an app I am allowing user to pick image from gallery or he can choose from camera. Though I can manage the image and show it in the activity in the first time, after closing the app and restarting it, the image is gone and the space is blank.There was an explanation given to me to save the image data in sharedPreferences but I am new in android and don't pretty much understand. I looked for sharedPreferences but don't know how to make it work.
So if anybody help kindly with some explanation and code, it would help me a lot.
Thanks.
Here is what I tried to do.
private void openCamera(){
// create Intent to take a picture and return control to the calling application
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT,getPhotoFileUri(photoFileName)); // set the image file name
// If you call startActivityForResult() using an intent that no app can handle, your app will crash.
// So as long as the result is not null, it's safe to use the intent.
if (intent.resolveActivity(getPackageManager()) != null) {
// Start the image capture intent to take photo
startActivityForResult(intent, TAKE_IMAGE);
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// final android.widget.LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) imageview.getLayoutParams();
if (requestCode == PICK_IMAGE && resultCode == RESULT_OK) {
Uri imageUri = data.getData();
imageview.setImageURI(imageUri);
//selectedImagePath = getPath(imageUri);
//ystem.out.println("Image Path : " + selectedImagePath);
}
else if (requestCode == TAKE_IMAGE && resultCode == Activity.RESULT_OK) {
Uri takenPhotoUri = getPhotoFileUri(photoFileName);
// by this point we have the camera photo on disk
Bitmap rawTakenImage = BitmapFactory.decodeFile(takenPhotoUri.getPath());
// RESIZE BITMAP, see section below
// See BitmapScaler.java: https://gist.github.com/nesquena/3885707fd3773c09f1bb
// Get height or width of screen at runtime
int screenWidth = DeviceDimensionsHelper.getDisplayWidth(this);
// Resize a Bitmap maintaining aspect ratio based on screen width
Bitmap resizedBitmap = BitmapScaler.scaleToFitWidth(rawTakenImage,screenWidth);
// Load the taken image into a preview
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
// Compress the image further
resizedBitmap.compress(Bitmap.CompressFormat.JPEG, 40, bytes);
// Create a new file for the resized bitmap (`getPhotoFileUri` defined above)
Uri resizedUri = getPhotoFileUri(photoFileName + "_resized");
File resizedFile = new File(resizedUri.getPath());
// Write the bytes of the bitmap to file
try{
resizedFile.createNewFile();
FileOutputStream fos = new FileOutputStream(resizedFile);
fos.write(bytes.toByteArray());
fos.close();
}catch (IOException e){
System.out.println("Error occured");
}
imageview.setImageBitmap(rawTakenImage);
}
}
public Uri getPhotoFileUri(String fileName) {
// Only continue if the SD Card is mounted
if (isExternalStorageAvailable()) {
// Get safe storage directory for photos
// Use `getExternalFilesDir` on Context to access package-specific directories.
// This way, we don't need to request external read/write runtime permissions.
File mediaStorageDir = new File(
getExternalFilesDir(Environment.DIRECTORY_PICTURES), APP_TAG);
// Create the storage directory if it does not exist
if (!mediaStorageDir.exists() && !mediaStorageDir.mkdirs()){
Log.d(APP_TAG, "failed to create directory");
}
// Return the file target for the photo based on filename
return Uri.fromFile(new File(mediaStorageDir.getPath() + File.separator + fileName));
}
return null;
}
// Returns true if external storage for photos is available
private boolean isExternalStorageAvailable() {
String state = Environment.getExternalStorageState();
return state.equals(Environment.MEDIA_MOUNTED);
}
You can use below ways to store image.
1. Database with Base64
You can convert image into base64 string and store in database.
So when you open application you can retrieve base64 String from database and display image in ImageView.
2. Store Image Path in Database
You can store image path in database, when you open application, just retrieve image path and display image in ImageView.
But if you delete image from memory, you will not get image from iamge path.
3. Store Image in Server.
If you store image in server, you can retrieve image path and download image using AsyncTask or sime 3rd party liberary. And display image in ImageView.
(Liberaries : Picaso, LazyLoading etc.)
In my code I allow user to upload photos from gallery or from camera. Then image is stored into the server through retrofit. When retrieved the photo is always rotated 90 degrees if the photo is taken using the phone's camera (regardless whether it is from invoked through the app or invoked through the camera directly). If the images are not taken using the camera, the orientation is correct. How do I resolve this?
I know if I tried to display the image directly without storing it in server, and it was possible to be in the right orientation because I could rotate it before displaying. I am doing something similar to the codes here: https://gist.github.com/Mariovc/f06e70ebe8ca52fbbbe2.
But because I need to upload to the server and then retrieve from the server again. How do I rotate it before storing to the server so that when I retrieve it, it is already in the right orientation?
Below is some parts of my codes (just some usual handling of images and displayAvatarInProfile() is called after the service finished the downloading of image):
public void displayAvatarInProfile(String filePath) {
if(filePath != null && filePath != ""){
int targetW = mProfilePicImageView.getWidth();
int targetH = mProfilePicImageView.getHeight();
Bitmap bm = ImageStorageUtils.resizePic(filePath, targetW, targetH);
mProfilePicImageView.setImageBitmap(bm);
} else {
mProfilePicImageView.setImageBitmap(null);
}
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if(resultCode == Activity.RESULT_OK) {
Uri fileUri = null;
String filePath = null;
switch(requestCode) {
case REQUEST_PICK_IMAGE:
fileUri = data.getData();
break;
case REQUEST_CAPTURE_IMAGE:
File imageFile = ImageStorageUtils.getFile(
getActivity().getResources().getString(R.string.ApptTitle),
"avatar_" + mUser.getLogin());
filePath = imageFile.getAbsolutePath();
fileUri = ImageStorageUtils.getUriFromFilePath(mContext.get(), filePath);
break;
default:
break;
}
if(fileUri != null) {
getActivity().startService(ProfileService.makeIntentUploadAvatar(
mContext.get(), mUser.getId(), fileUri));
}
}
}
public void pickImage() {
final Intent imageGalleryIntent =
new Intent(Intent.ACTION_PICK, Media.EXTERNAL_CONTENT_URI)
.setType("image/*")
.putExtra(Intent.EXTRA_LOCAL_ONLY, true);
// Verify the intent will resolve to an Activity.
if (imageGalleryIntent.resolveActivity(getActivity().getPackageManager()) != null)
// Start an Activity to get the Image from the Image Gallery
startActivityForResult(imageGalleryIntent,
DisplayProfileFragment.REQUEST_PICK_IMAGE);
}
public void captureImage() {
Uri captureImageUri = null;
try {
captureImageUri = Uri.fromFile(ImageStorageUtils.createImageFile(
mContext.get(),
getActivity().getResources().getString(R.string.ApptTitle),
"avatar_" + mUser.getLogin()));
} catch (IOException e) {
e.printStackTrace();
}
// Create an intent that will start an Activity to get
// capture an image.
final Intent captureImageIntent =
new Intent(MediaStore.ACTION_IMAGE_CAPTURE)
.putExtra(MediaStore.EXTRA_OUTPUT, captureImageUri);
// Verify the intent will resolve to an Activity.
if (captureImageIntent.resolveActivity(getActivity().getPackageManager()) != null)
// Start an Activity to capture an image
startActivityForResult(captureImageIntent,
DisplayProfileFragment.REQUEST_CAPTURE_IMAGE);
}
Update 1
Was commented that I needed more description:
When I am uploading a file, I do this:
boolean succeeded = mImpatientServiceProxy.uploadAvatar(userId, new TypedFile("image/jpg", imageFile));
When I download, I get a retrofit.client.Response object, which I then get the InputStream from the Response and write the data to a file using an Output Stream.
final InputStream inputStream = response.getBody().in();
final OutputStream outputStream = new FileOutputStream(file);
IOUtils.copy(inputStream, outputStream);
Update 2
This is not a duplicate of existing solution because the user can upload from gallery, you do not know if it is a photo taken from resources online or from camera, so you cannot rotate the image when you display it.
Use camera api instead of intent. When you capture image using intents it displays rotated. In camera api there are methods by which you can change the rotation of the camera as well as the captured photo too.
In my application I capture photo by android camera and then I want to send it to the server. For this I use Client Socket programming. I convert the capture photo into bytearray(byte[]) and then send it to the server. Every thing work perfactally.
Problem is there I am not able to send original photo to the server. Thumbnail photo is sended by the android mobile phone. But when I capture photo by the camera then original photo is there in Gallery.
How to get this original photo to use in my application?
My Code:
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra("outputFormat",Bitmap.CompressFormat.JPEG);
cameraIntent.putExtra("return-data", true);
startActivityForResult(Intent.createChooser(cameraIntent, "Select Picture"),
CAMERA_REQUEST);
And in onActivityResult method:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_REQUEST) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
// byte[] a = (byte[]) data.getExtras().getByteArray("data"); // I also use this but not work
ByteArrayOutputStream bos = new ByteArrayOutputStream();
photo.compress(CompressFormat.JPEG, 100, bos);
byte[] bitmapdata = bos.toByteArray();
}
}
in bitmapdata photo is there but compressed photo not the original.
Some of people say that, change quality field of compress(CompressFormat.JPEG, 100, bos); in between 0 to 100 but nothing will happen.
-- >> is there any other way also to get original photo which is captured by the camera
-- >> When The photo is in folder of my computer then I read this photo in the file by giving the path. ex- File file = new File(c:\newphoto\image.jpg); . can I use this code in android to read original photo because I know the name and location of photo. If yes then what is the path to read photo in gallery. Is this work if I give path as: \DCIM\Camera\photoName.jpg.
-- >> Or some change need in my current code and it will work fine?
You are using the Intent to capture the image using ACTION_IMAGE_CAPTURE. If you normally starts your camera using Intent then it will return image as a bitmap in onActivityResult() but it will be for thumbnail purpose.
If you want to get full resolution image from the camera then you should provide a file with the intent which you are firing to start the camera activity.
You can do like below
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
File out = Environment.getExternalStorageDirectory();
out = new File(out, imagename);
i.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(out));
startActivityForResult(i, CAMERA_RESULT);
Here there is a MediaStore.EXTRA_OUTPUT parameter which takes a Uri of the file in which you want your camera to write a images.
For more information you can refer below example
Capture full resolution image from camera
I've got a problem in saving a picture in a full size after capturing it using ACTION_IMAGE_CAPTURE intent the picture become very small , its resolution is 27X44 I'm using 1.5 android emulator, this is the code and I will appreciate any help:
myImageButton02.setOnClickListener
(
new OnClickListener()
{
#Override
public void onClick(View v)
{
// create camera intent
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
//Grant permission to the camera activity to write the photo.
intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
//saving if there is EXTRA_OUTPUT
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File
(Environment.getExternalStorageDirectory(), "testExtra" + String.valueOf
(System.currentTimeMillis()) + ".jpg")));
// start the camera intent and return the image
startActivityForResult(intent,1);
}
}
);
#Override
protected void onActivityResult (int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
// if Activity was canceled, display a Toast message
if (resultCode == RESULT_CANCELED)
{
Toast toast = Toast.makeText(this,"camera cancelled", 10000);
toast.show();
return;
}
// lets check if we are really dealing with a picture
if (requestCode == 1 && resultCode == RESULT_OK)
{
String timestamp = Long.toString(System.currentTimeMillis());
// get the picture
Bitmap mPicture = (Bitmap) data.getExtras().get("data");
// save image to gallery
MediaStore.Images.Media.insertImage(getContentResolver(), mPicture, timestamp, timestamp);
}
}
}
Look at what you are doing:
you specify a path where your just taken picture is stored with intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File (Environment.getExternalStorageDirectory(), "testExtra" + String.valueOf (System.currentTimeMillis()) + ".jpg")));
when you access the picture you 'drag' the data out of the intent with Bitmap mPicture = (Bitmap) data.getExtras().get("data");
Obviously, you don't access the picture from its file. As far as I know Intents are not designed to carry a large amount of data since they are passed between e.g. Activities. What you should do is open the picture from the file created by the camera intent. Looks like that:
BitmapFactory.Options bitmapOptions = new BitmapFactory.Options();
// Limit the filesize since 5MP pictures will kill you RAM
bitmapOptions.inSampleSize = 6;
imgBitmap = BitmapFactory.decodeFile(pathToPicture, bitmapOptions);
That should do the trick. It used to work for me this way but I am experiencing problems since 2.1 on several devices. Works (still) fine on Nexus One.
Take a look at MediaStore.ACTION_IMAGE_CAPTURE.
Hope this helps.

For my application, I'd been using my own Camera class for taking images and my own database but soon enough I couldn't really keep up with changes and I decided to use the built in camera application in Android to do the job, but I can't seem to get it to save file. What am I missing here? The application seems to save the file but it's just 0 bytes. I looked up the source code of the Camera application and it's looking for the "output" in Extras to save the file. Any help would be greatly appreciated.
Public class CameraTest extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button cameraButton = (Button) findViewById(R.id.cameraButton);
cameraButton.setOnClickListener( new OnClickListener(){
public void onClick(View v ){
ContentValues values = new ContentValues();
values.put(Images.Media.TITLE, "title");
values.put(Images.Media.BUCKET_ID, "test");
values.put(Images.Media.DESCRIPTION, "test Image taken");
Uri uri = getContentResolver().insert(Media.EXTERNAL_CONTENT_URI, values);
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
intent.putExtra("output", uri.getPath());
startActivityForResult(intent,0);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode== 0 && resultCode == Activity.RESULT_OK){
((ImageView)findViewById(R.id.pictureView)).setImageURI(data.getData());
}
}
}
This worked with the following code, granted I was being a little dumb with the last one. I still think there's got to be a better way so that the original image is still saved somewhere. It still sends me the smaller 25% size image.
public class CameraTest extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button cameraButton = (Button) findViewById(R.id.cameraButton);
cameraButton.setOnClickListener( new OnClickListener(){
public void onClick(View v ){
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
startActivityForResult(intent,0);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode== 0 && resultCode == Activity.RESULT_OK) {
Bitmap x = (Bitmap) data.getExtras().get("data");
((ImageView)findViewById(R.id.pictureView)).setImageBitmap(x);
ContentValues values = new ContentValues();
values.put(Images.Media.TITLE, "title");
values.put(Images.Media.BUCKET_ID, "test");
values.put(Images.Media.DESCRIPTION, "test Image taken");
values.put(Images.Media.MIME_TYPE, "image/jpeg");
Uri uri = getContentResolver().insert(Media.EXTERNAL_CONTENT_URI, values);
OutputStream outstream;
try {
outstream = getContentResolver().openOutputStream(uri);
x.compress(Bitmap.CompressFormat.JPEG, 70, outstream);
outstream.close();
} catch (FileNotFoundException e) {
//
} catch (IOException e) {
//
}
}
}
Also, I do know that the cupcake release of Android should fix the small image size soon.
The below code will start the default camera and have the camera save the image to the specified uri. The key is to put the extra "MediaStore.EXTRA_OUTPUT" along with the desired uri.
File file = new File(Environment.getExternalStorageDirectory().getPath() + "/Images/" + image_name + ".jpg");
Uri imageUri = Uri.fromFile(file);
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(intent, 0);
In your first attempt, it could be that the Camera app crashes when it reads your "output" extra, since it expects it to be a Uri, while you provide a String. The Camera app seems to read the extra flag after capturing the photo. You should just provide uri, and not uri.getPath(). Then, since you already know the URI to the photo, it will not be returned in the onResult call. You need to remember the URI in a member variable.
In the second attempt you will get a scaled down (50%) bitmap back. It is primarily intended for views. I think the full sized bitmap is too large for the memory budget of the application. This may be the reason for the downscale.
FYI , found this on docs :
The caller may pass an extra EXTRA_OUTPUT to control where this image will be written. If the EXTRA_OUTPUT is not present, then a small sized image is returned as a Bitmap object in the extra field. This is useful for applications that only need a small image. If the EXTRA_OUTPUT is present, then the full-sized image will be written to the Uri value of EXTRA_OUTPUT.
located here :http://developer.android.com/reference/android/provider/MediaStore.html
so the app can save full size image for you , if you tell it where.
**Edit : This is not the case with HTC devices. HTC (not nexus) that uses htc sense ui have branched from android 1.5 and carry a bug that always save the image in low res. you can lunch activity for camera and use the share function from camera to use the full sized image.
I got the same Problem with the Emulator,
I tried it on a real Phone an it worked,
maybe it is because the Virtual Phone can't really take Picures.
