当我在一个活动中从图库加载两个图像时，内存不足问题位图

Question

我正在开发一个相框应用程序。用户可以在一个框架中从图库中选择两张图像。但是每当我从图库中设置任何一个图像然后选择其他图像时，应用程序崩溃并在日志中显示内存不足的错误消息。如何删除这个错误

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        try {
            // When an Image is picked
            if (requestCode == 10 && resultCode == RESULT_OK
                    && null != data) {
                // Get the Image from data
                Uri selectedImage = data.getData();
                String[] filePathColumn = {MediaStore.Images.Media.DATA};
                // Get the cursor
                Cursor cursor = getContentResolver().query(selectedImage,
                        filePathColumn, null, null, null);
                // Move to first row
                cursor.moveToFirst();

                int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                imgDecodableString = cursor.getString(columnIndex);
                cursor.close();
                // Set the Image in ImageView after decoding the String

                imageView1.setImageBitmap(BitmapFactory
                        .decodeFile(imgDecodableString));

            }
            if (requestCode == 100 && resultCode == RESULT_OK
                    && null != data) {
                // Get the Image from data
                Uri selectedImage = data.getData();
                String[] filePathColumn = {MediaStore.Images.Media.DATA};
                // Get the cursor
                Cursor cursor = getContentResolver().query(selectedImage,
                        filePathColumn, null, null, null);
                // Move to first row
                cursor.moveToFirst();
                int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                imgDecodableString = cursor.getString(columnIndex);
                cursor.close();

                // Set the Image in ImageView after decoding the String
               // 
                imageView2.setImageBitmap(BitmapFactory
                        .decodeFile(imgDecodableString));
            }
  }

请帮帮我

请尝试下面的代码，希望对您有所帮助

public static Bitmap decodeFile(File file, int width, int height)
    {
        try
        {
            //Decode image size
            BitmapFactory.Options o = new BitmapFactory.Options();
            o.inJustDecodeBounds = true;
            BitmapFactory.decodeStream(new FileInputStream(file), null, o);
            int scale = 1;
            //The new size we want to scale to
            final int REQUIRED_WIDTH = width;
            final int REQUIRED_HIGHT = height;

            //Find the correct scale value. It should be the power of 2.
            while (o.outWidth / scale / 2 >= REQUIRED_WIDTH && o.outHeight / scale / 2 >= REQUIRED_HIGHT)
            {
                scale *= 2;
            }
            //Decode with inSampleSize
            BitmapFactory.Options o2 = new BitmapFactory.Options();
            o2.inSampleSize = scale;
            return BitmapFactory.decodeStream(new FileInputStream(file), null, o2);
        }
        catch (FileNotFoundException e)
        {
        }
        return null;
    }
