I'm trying to take a screenshot using a background service. This service is like a Facebook chathead, but I want it to take an screenshot when I do a click.
I've developed some code but it doesn't work. The last I've tried was:
private void takeScreenshot() {
Date now = new Date();
android.text.format.DateFormat.format("yyyy-MM-dd_hh:mm:ss", now);
// image naming and path to include sd card appending name you choose for file
String mPath = Environment.getExternalStorageDirectory().toString() + "/capture/" + now + ".jpg";
// create bitmap screen capture
Bitmap bitmap;
View v1 = chatHead.getRootView();
v1.setDrawingCacheEnabled(true);
bitmap = Bitmap.createBitmap(v1.getDrawingCache());
v1.setDrawingCacheEnabled(false);
OutputStream fout = null;
File imageFile = new File(mPath);
try {
fout = new FileOutputStream(imageFile);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fout);
fout.flush();
fout.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
But is taking an screenshot to my button not to the screen.
I know the problem is here:
View v1 = chatHead.getRootView();
But I don't know how to fix it. Can anyone help me?
I'm actually using Android Studio 2.2.2 and Android 4.0 or greater.
