App is crashing after capturing picture using intents

Question

My app is crashing after capturing 5 to 6 photos using intents.log cat shows nothing. am unable to find the reason why it is crashing. please help me out.

    private void capturePhoto() {

        File root = new File(Environment.getExternalStorageDirectory(), "Feedback");
        if (!root.exists()) {
            root.mkdirs();
        }
        File file = new File(root, Constants.PROFILE_IMAGE_NAME + ".jpeg");
        Uri outputFileUri = Uri.fromFile(file);


        Intent photoPickerIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        photoPickerIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
        photoPickerIntent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString());
        photoPickerIntent.putExtra("return-data", true);
        photoPickerIntent.putExtra("android.intent.extras.CAMERA_FACING", 1);
        startActivityForResult(photoPickerIntent, requestCode);


    }


    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (this.requestCode == requestCode && resultCode == RESULT_OK) {

            File root = new File(Environment.getExternalStorageDirectory(), "Feedback");
            if (!root.exists()) {
                root.mkdirs();
            }
            File file = new File(root, Constants.PROFILE_IMAGE_NAME+".jpeg");
            checkFlowIdisPresent(file);

            displayPic();


        }
    }
  private void displayPic() {

        String filePath = Environment.getExternalStorageDirectory()
                .getAbsolutePath() + File.separator + "/Feedback/" + Constants.PROFILE_IMAGE_NAME + ".jpeg";
        //  Bitmap bmp = BitmapFactory.decodeFile(filePath);
        //Bitmap scaled = Bitmap.createScaledBitmap(bmp, 300, 300, true);


        File imgFile = new File(filePath);
        Bitmap bmp = decodeFile(imgFile);

        if (imgFile.exists()) {

            dispProfilePic.setImageBitmap(bmp);
        } else {
            dispProfilePic.setBackgroundResource(R.drawable.user_image);

        }
    }

 private Bitmap decodeFile(File f) {
        try {
            // Decode image size
            BitmapFactory.Options o = new BitmapFactory.Options();
            o.inJustDecodeBounds = true;
            BitmapFactory.decodeStream(new FileInputStream(f), null, o);

            // The new size we want to scale to
            final int REQUIRED_SIZE = 70;

            // Find the correct scale value. It should be the power of 2.
            int scale = 1;
            while (o.outWidth / scale / 2 >= REQUIRED_SIZE &&
                    o.outHeight / scale / 2 >= REQUIRED_SIZE) {
                scale *= 2;
            }

            // Decode with inSampleSize
            BitmapFactory.Options o2 = new BitmapFactory.Options();
            o2.inSampleSize = scale;
            return BitmapFactory.decodeStream(new FileInputStream(f), null, o2);
        } catch (FileNotFoundException e) {
        }
        return null;
    }

And above code is for capturing photo and displaying captured picture in ImageView. And am using MI tab.

Edit actually app is not crashing...it becomes white screen and if i press any button then it is crashing and onActivityResult is not executed when it become white screen

New Edit Am able to replicate this. I clicked on Android Monitor in that i clicked Monitor. Then it shows memory utilization of the app when i interacting with app. now in left side bar i clicked terminate application icon. Now the interesting thing is it destroys current activity and moves to previous activity. That previous activity become white screen.

Please help me out guys.

Try this code. I use it in some of my apps :

Launch intent method:

private void launchCamera() {
        Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
    }

Capturing result:

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        try {
            if (requestCode == CAMERA_PIC_REQUEST) {
                if (data != null) {
                    Bundle extras = data.getExtras();
                    if (extras != null) {
                        Bitmap thumbnail = (Bitmap) extras.get("data");
                        if (thumbnail != null)
                            displayPic(thumbnail);
                    }
                }
            }
            } catch (Exception e) {
            e.printStackTrace();
            }
    }

Well your code fine....

I think you save the image or overwrite image on same path with same name so there is problem with memory. So I recommended you change the name with System.currentTimeMillis() or any random name Instead of Constants.PROFILE_IMAGE_NAME.

And Also check the permission

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

Also check this permission with run time also...for run time follow this

private static final int REQUEST_RUNTIME_PERMISSION = 123;


    if (CheckPermission(demo.this, Manifest.permission.WRITE_EXTERNAL_STORAGE)) {


        capturePhoto();

    } else {
        // you do not have permission go request runtime permissions
        RequestPermission(demo.this, Manifest.permission.WRITE_EXTERNAL_STORAGE, REQUEST_RUNTIME_PERMISSION);
    }



public void RequestPermission(Activity thisActivity, String Permission, int Code) {
        if (ContextCompat.checkSelfPermission(thisActivity,
                Permission)
                != PackageManager.PERMISSION_GRANTED) {
            if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity,
                    Permission)) {
                capturePhoto();

            } else {
                ActivityCompat.requestPermissions(thisActivity,
                        new String[]{Permission},
                        Code);
            }
        }
    }

    public boolean CheckPermission(Activity context, String Permission) {
        if (ContextCompat.checkSelfPermission(context,
                Permission) == PackageManager.PERMISSION_GRANTED) {
            return true;
        } else {
            return false;
        }
    }
