Screenshot detection API-Android14
Published in
2 min readMar 14, 2023
Android 14 introduces a privacy-preserving screenshot detection API to create a more standardized screenshot detection experience.
Apps can register callbacks on a per-activity basis using this API.
If the user takes a screenshot while that activity is visible, these callbacks are invoked, and the user is notified.
A screenshot can only be detected if the user presses a specific combination of hardware buttons.
Implementation
Add permission to Manifest
- This is an
install-time permission, so we do not need to worry about it during runtime 🙌
<uses-permission android:name="android.permission.DETECT_SCREEN_CAPTURE" />Implement ScreenCaptureCallback interface
- A method called
onScreenCaptured()needs to be overridden.
@RequiresApi(Build.VERSION_CODES.UPSIDE_DOWN_CAKE)
class MainActivity : ComponentActivity(), Activity.ScreenCaptureCallback {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
Text("Screenshot Detection API")
}
}
override fun onStart() {
super.onStart()
// Register callback to detect screenshot
registerScreenCaptureCallback(mainExecutor, this)
}
override fun onStop() {
super.onStop()
// unregister callback to detect screenshot
unregisterScreenCaptureCallback(this)
}
override fun onScreenCaptured() {
// Inform the user or do whatever you want
Log.d(TAG, "onScreenCaptured: Screenshot detected")
}
companion object {
const val TAG = "MainActivity"
}
}Demo
- As I do not have an Android 14 device, the following screenshot comes from the official documentation.
