Picking a photo from gallery and show in a image view

Question

I have an app, which has a button to select a photo from your gallery and it works fine and after selecting the image my app show came back to the activity and shows the image in an image View.

Every is working fine but sometimes ,when i select some particular images the preview is not showing. I have also tried to compress the image still its not working

My code is below.. In onCreate()

galeryBtn=(Button)findViewById(R.id.buttonGallery);
galeryBtn.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {
      Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
      startActivityForResult(i, RESULT_LOAD_IMAGE);

    }
});

In onActivityResult(int requestCode, int resultCode, Intent data)

if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
    Uri selectedImage = data.getData();
    String[] filePathColumn = { MediaStore.Images.Media.DATA };

    Cursor cursor = getContentResolver().query(selectedImage,filePathColumn, null, null, null);
    cursor.moveToFirst();

    int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
    String picturePath = cursor.getString(columnIndex);
    cursor.close();
    // String picturePath contains the path of selected Image

    // Show the Selected Image on ImageView
    ImageView imageView = (ImageView) findViewById(R.id.imgView);
    imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));

}

Try like this

public void onActivityResult(int requestCode, int resultCode, Intent intent) {
        super.onActivityResult(requestCode, resultCode, intent);

        switch (requestCode) {
                case RESULT_LOAD_IMAGE:
            if (resultCode == Activity.RESULT_OK) {

                Uri selectedImage = intent.getData();
                try {
                    Bitmap bitmapImage =decodeBitmap(selectedImage );
                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                }
                                // Show the Selected Image on ImageView
                    ImageView imageView = (ImageView) findViewById(R.id.imgView);
                    imageView.setImageBitmap(bitmapImage);

            }

And

public  Bitmap decodeBitmap(Uri selectedImage) throws FileNotFoundException {
        BitmapFactory.Options o = new BitmapFactory.Options();
        o.inJustDecodeBounds = true;
        BitmapFactory.decodeStream(getContentResolver().openInputStream(selectedImage), null, o);

        final int REQUIRED_SIZE = 100;

        int width_tmp = o.outWidth, height_tmp = o.outHeight;
        int scale = 1;
        while (true) {
            if (width_tmp / 2 < REQUIRED_SIZE || height_tmp / 2 < REQUIRED_SIZE) {
                break;
            }
            width_tmp /= 2;
            height_tmp /= 2;
            scale *= 2;
        }

        BitmapFactory.Options o2 = new BitmapFactory.Options();
        o2.inSampleSize = scale;
        return BitmapFactory.decodeStream(getContentResolver().openInputStream(selectedImage), null, o2);
    }
