getting mSignatureView.getDrawingCache() as null

[akshay2211]

is there any way to get bitmap of this FreeDrawView
as this listener is also always giving error
mSignatureView.getDrawScreenshot(new FreeDrawView.DrawCreatorListener() { @Override public void onDrawCreated(Bitmap draw) { // The draw Bitmap is the drawn content of the View } @Override public void onDrawCreationError() { // Something went wrong creating the bitmap, should never // happen unless the async task has been canceled } });
