位图在android版本棉花糖和棒棒糖中不起作用？

当我使用下面的代码时，这段代码适用于android kitkat版本，但在棒棒糖和棉花糖版本中不起作用。当我选择一个图像时，它不会显示在imageview中，并在棒棒糖和棉花糖中抛出一个异常

这里我附上了我的代码，用于在点击按钮时显示来自图库的图像

FloatingActionButton pick = (FloatingActionButton) findViewById(R.id.pick);
    pick.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent intent = new Intent();

            intent.setType("image/*");
            intent.setAction(Intent.ACTION_GET_CONTENT);

            startActivityForResult(Intent.createChooser(intent, "Complete action using"), PICK_FROM_FILE);

            }
    });
    @Override
    protected  void onActivityResult(int requestCode, int resultCode, Intent data){ 
        super.onActivityResult(requestCode, resultCode, data);
        try {

        if (requestCode == PICK_FROM_FILE && 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]);
            imgDecodableString = cursor.getString(columnIndex);
            cursor.close();
            BitmapFactory.Options options = new BitmapFactory.Options();
            options.inSampleSize = 4;

            Bitmap bitmap = BitmapFactory.decodeFile(imgDecodableString,options);
            ImageView imgView = (ImageView) findViewById(R.id.imageView);
            int height = bitmap.getHeight() * 4, width = bitmap.getWidth() * 4;
            Toast.makeText(this, "Height" + height + "Width" + width, Toast.LENGTH_LONG).show();

            if (height > 4096 || width > 4096){
                bitmap1 = BitmapFactory.decodeFile(imgDecodableString,options);
                imgView.setImageBitmap(bitmap1);
                Toast.makeText(this, "Need to Resize", Toast.LENGTH_LONG).show();

            }else {
                bitmap1 = BitmapFactory.decodeFile(imgDecodableString);
                imgView.setImageBitmap(bitmap1);
                Toast.makeText(this, "Works", Toast.LENGTH_LONG).show();

            }



        } else {
            Toast.makeText(this, "You haven't picked Image",
                    Toast.LENGTH_LONG).show();
        }
    } catch (Exception e) {
        Toast.makeText(this, "Something went wrong", Toast.LENGTH_LONG)
                .show();
    }
}

请添加异常的stacktrace代码。可能报告的问题：我发现所有上述kitkat版本的“从库中拾取图像”代码都不同。请添加异常的stacktrace代码。可能报告的问题：我发现所有上述kitkat版本的“从库中拾取图像”代码都不同。
