I am running ScheduledExecutorService inside of my service which takes image in background. ScheduledExecutorService running only once means taking only one picture after the interval passed in function. Showing no errors at all. Following is the code of my Service

FileOutputStream outStream = null;
try {
// write to local sand box file system
// outStream =
// CameraDemo.this.openFileOutput(String.format("%d.jpg",
// System.currentTimeMillis()), 0);
// Or write to s d card
File mFolder;
mFolder = new File("/sdcard/Spy/");
if (!mFolder.exists()) {
mFolder.mkdir();
}
outStream = new FileOutputStream(String.format(
"/sdcard/Spy/Image_%d.jpg", System.currentTimeMillis()));
outStream.write(data);
outStream.close();
Log.d(TAG, "onPictureTaken - wrote bytes: " + data.length);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
}
Log.d(TAG, "onPictureTaken - jpeg");
}
};
}
No Logcat because not getting any error. Service is also running after taking picture. What I am doing wrong?
