I had tried alot & even search alot but i didn’t found
the solution about the black screen
which i get by fetching the cache view on the surface view..
if is there any other way to capture the screen then let me know about this..
if i use another control & fetching the drawable cache of that control it also return null..
this is the code which i used to fetch the screen Image….
try {
// Button btn = new Button(mActivity.getApplicationContext());
view.buildDrawingCache();
view.setDrawingCacheEnabled(true);
Bitmap b = view.getDrawingCache();
b.compress(CompressFormat.JPEG, 100, new FileOutputStream(
"/mnt/sdcard/documents/" + new Date().getTime() + ".JPEG"));
} catch (Exception e) {
e.printStackTrace();
}
i had used this on the touch_up action of the surface view…..
