Question

I’m trying to save a Layout into an Image in the SDCard but I get this error. I tried several codes I found in this forum but all of them have the same compress call that is giving the error.

This is the code I use for saving the image:

private Bitmap TakeImage(View v) {
        Bitmap screen = null;
        try {
            v.setDrawingCacheEnabled(true);

            v.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED),
                    MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
            v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight());

            v.buildDrawingCache(true);
            screen = v.getDrawingCache();
            v.setDrawingCacheEnabled(false); // clear drawing cache
        } catch (Exception e) {
            e.printStackTrace();
        }
        return screen;
    }

And this is the code for saving it in the SDCard:

private void saveGraph(Bitmap graph, Context context) throws IOException {
        OutputStream fOut = null;
        File file = new File(Environment.getExternalStorageDirectory()
                + File.separator + "test.jpg");
        fOut = new FileOutputStream(file);

        graph.compress(Bitmap.CompressFormat.JPEG, 85, fOut);
        fOut.flush();
        fOut.close();

        MediaStore.Images.Media.insertImage(getContentResolver(),
                file.getAbsolutePath(), file.getName(), file.getName());
}

I’m getting the error:

Can’t compress a recycled bitmap in the compress call!

Answer 1

This is probably causing the bitmap to be recycled:

v.setDrawingCacheEnabled(false); // clear drawing cache

If you want the bitmap to hang around longer, then you should copy it.
