拍照后未调用onActivityResult

Question

How know that subject is well documented and I have read a lot on that issue, but I still have the following problem: when I take a picture with my app and click on "validate" button, nothing occur. The aime of what I am doing: passing to onActivityReult function not only the thumbnail, but the "whole" picture taken by the camera.

Here is the listener as defined for the "take a picture" button:

@Override
        public void onClick(View v) {
            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

            File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "CameraTest");
            mediaStorageDir.mkdir(); // make sure you got this folder
            Log.i("Report",mediaStorageDir.toString());
            String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
            File mediaFile = new File(mediaStorageDir.getPath() + File.separator + "IMG_"+ timeStamp + ".jpg");

            try
            {
                //create directories and the file
                mediaFile.getParentFile().mkdirs();
                mediaFile.createNewFile();
            } catch (IOException e) { 
                Log.e("Report", "create error for file "+mediaFile);
                e.printStackTrace();
            }
            mFileUri = Uri.fromFile(mediaFile);
            Log.i("Report","Uri: "+mFileUri);
            intent.putExtra(MediaStore.EXTRA_OUTPUT, mFileUri);// this line causes issue - onActivityResult not called...
            startActivityForResult(intent, CAMERA_PIC_REQUEST);
}
});

and here is the onActivityResult method... that is never called (and that is not declared in the onClickListener method):

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    Log.d("Report", "1");
    if (resultCode == Activity.RESULT_OK) {
        if (requestCode == CAMERA_PIC_REQUEST) {
            try {
                String[] projection = {
                        MediaStore.Images.Thumbnails._ID, // The columns we want
                        MediaStore.Images.Thumbnails.IMAGE_ID,
                        MediaStore.Images.Thumbnails.KIND,
                        MediaStore.Images.Thumbnails.DATA };
                String selection = MediaStore.Images.Thumbnails.KIND + "=" + 
                        MediaStore.Images.Thumbnails.MINI_KIND;
                String sort = MediaStore.Images.Thumbnails._ID + " DESC";
                Cursor myCursor = this.managedQuery(
                        MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI,
                        projection, selection, null, sort);
                Log.d("Report", "3");
                long imageId = 0l;
                long thumbnailImageId = 0l;
                String thumbnailPath = "";

                try {
                    myCursor.moveToFirst();
                    imageId = myCursor
                            .getLong(myCursor
                                    .getColumnIndexOrThrow(MediaStore.Images.Thumbnails.IMAGE_ID));
                    thumbnailImageId = myCursor
                            .getLong(myCursor
                                    .getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID));
                    thumbnailPath = myCursor
                            .getString(myCursor
                                    .getColumnIndexOrThrow(MediaStore.Images.Thumbnails.DATA));
                } finally {
                    myCursor.close();
                }

                String[] largeFileProjection = {
                        MediaStore.Images.ImageColumns._ID,
                        MediaStore.Images.ImageColumns.DATA };

                String largeFileSort = MediaStore.Images.ImageColumns._ID
                        + " DESC";
                myCursor = this.managedQuery(
                        MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                        largeFileProjection, null, null, largeFileSort);
                String largeImagePath = "";

                try {
                    myCursor.moveToFirst();

                    // This will actually give yo uthe file path location of the
                    // image.
                    largeImagePath = myCursor
                            .getString(myCursor
                                    .getColumnIndexOrThrow(MediaStore.Images.ImageColumns.DATA));
                    mImageCaptureUri = Uri.fromFile(new File(
                            largeImagePath));

                } finally {
                    // myCursor.close();
                }
                Uri uriLargeImage = Uri.withAppendedPath(
                        MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                        String.valueOf(imageId));
                Uri uriThumbnailImage = Uri.withAppendedPath(
                        MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI,
                        String.valueOf(thumbnailImageId));

                Bitmap thumbnail = MediaStore.Images.Media.getBitmap(this.getContentResolver(), uriThumbnailImage);
                Bitmap image = MediaStore.Images.Media.getBitmap(this.getContentResolver(), uriLargeImage);

But, as said in the title, onActivityResult is not called. Could you please find out why? Because I have tried almost everything I have found on that subject but I should have missed something.

Thanks !

Answer 1

check if you have declared the right permissions in the AndroidManifest.xml

<uses-permission android:name="android.permission.CAMERA"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

and be sure the file you want to write into exists:
add this below puc_img = new File(photo,"Puc_Img.jpg");

try
{
    //create directories and the file
    puc_file.getParentFile().mkdirs();
    puc_file.createNewFile();
} catch (IOException e) { }

It's not clear from your code but you could be declaring onActivityResult within your onClickListener . If that's true you need to move it. Take a look at this answer:

OnActivityResult ()

Answer 3

Ok, to solve that issue, I used some "trick" detailed here:

@Override
        public void onClick(View v) {
            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

            File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "CameraTest");
            mediaStorageDir.mkdir(); // make sure you got this folder
            Log.i("Report",mediaStorageDir.toString());
            String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
            File mediaFile = new File(mediaStorageDir.getPath() + File.separator + "IMG_"+ timeStamp + ".jpg");

            try
            {
                //create directories and the file
                mediaFile.getParentFile().mkdirs();
                mediaFile.createNewFile();
            } catch (IOException e) { 
                Log.e("Report", "create error for file "+mediaFile);
                e.printStackTrace();
            }
            tmpFilePath = mediaFile.getPath();
            mFileUri = Uri.fromFile(mediaFile);
            Log.i("Report","Uri: "+mFileUri);
            intent.putExtra(MediaStore.EXTRA_OUTPUT, mFileUri);
            startActivityForResult(intent, CAMERA_PIC_REQUEST);
        }

    });

So then, I am recovering the file stored in the tmpFilePath, by using that method in the onActivityResult function:

Bitmap image = BitmapFactory.decodeFile(this.tmpFilePath);

And... It's working fine. I still have some issues when sending the file to the WS but that very question have been solved by that piece of code. Thanks for the help, you put me on the track :)
