Question

I’m trying to capture image and save it in gallery. For that in onCreate my code

    Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
    File photo = new File(Environment.getExternalStorageDirectory(), "Pic.jpg");
    imageUri = Uri.fromFile(photo);
    intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
    startActivityForResult(intent, TAKE_PICTURE);

and

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK && requestCode == TAKE_PICTURE) {
        Log.v("data", "data: " + data);
        Bundle extras = data.getExtras();
        if (extras.containsKey("data")) {
            bitmap = (Bitmap) extras.get("data");
            // ByteArrayOutputStream baos = new ByteArrayOutputStream();
            // bmp.compress(Bitmap.CompressFormat.PNG, 100, baos);
            // byte[] image = baos.toByteArray();
            if (bitmap != null) {
                // BitmapFactory.Options options = new
                // BitmapFactory.Options();
                // options.inSampleSize = 5;
                // Bitmap myImage = BitmapFactory.decodeByteArray(image, 0,
                // image.length, options);
                imageView.setImageBitmap(bitmap);
            }
        } else {
            Toast.makeText(getBaseContext(), "Please capture again", Toast.LENGTH_LONG).show();
        }
        showPopUpForUpload();
    }
}

Now I’m able to capture image, but after that I’m getting error

The null pointer exception is on line

Bundle extras = data.getExtras();

So what is the problem?

Answer 1

I think its a problem of Android version 4.0 +.

Just try to remove,

File photo = new File(Environment.getExternalStorageDirectory(), "Pic.jpg");
imageUri = Uri.fromFile(photo);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);

When you call Capture intent. Now your resulted bundle onActivityResult() is not NULL.

Actually, When you are giving MediaStore.EXTRA_OUTPUT parameter to Camera Intent then camera application doesn’t callback with bundled data. (I find this issues in Android 4.0 +)

You have to get the Image file from Uri which you set as MediaStore.EXTRA_OUTPUT parameter.

Update:

Or use below pathFromUri() method and pass Uri which you are set to camera intent and get the Real File Path, now for this you don’t have to use Bundle extras = data.getExtras();

private String pathFromUri(Uri imageUri) {
    String[] filePathColumn = { MediaStore.Images.Media.DATA };
    Cursor cursor = getContentResolver().query(imageUri, filePathColumn,
                null, null, null);
    cursor.moveToFirst();
    int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
    String filePath = cursor.getString(columnIndex);
    return filePath ;
}
