Я создал простое приложение для Android, в котором я хочу захватить изображение и хочу установить его в imageview, но это дает мне исключение нулевого указателя внутри onActivityResult, мой logcattrace и код, как показано ниже: code

   public void onClick(DialogInterface dialog, int item) {

                if (options[item].equals("Take Photo"))

                {

                    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

                    File f = new File(android.os.Environment.getExternalStorageDirectory(), "temp.jpg");

                    intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));

                    startActivityForResult(intent, 1);

                }
...
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == RESULT_OK) {
        if (requestCode == SELECT_PICTURE) {
            Uri selectedImageUri = data.getData();
            if (Build.VERSION.SDK_INT < 19) {
                Log.i("Your version Build.VERSION.SDK_INT < 19","if condition");//<19
                selectedImagePath = getPath(selectedImageUri);
                bitmap_selected_image2 = BitmapFactory.decodeFile(selectedImagePath);
                v_iv_photo_main.setImageBitmap(bitmap_selected_image2);
                // finish();
               //  startActivity(new Intent(SelectPhotoCountryActivity.this,SetPhotoFrameActivity.class));

            }
