How to detect recent button in android 8.1.0 - keyboard

Question

I want to detect recent button but in android 8.1.0 it's not working.Below code is working on another version of android but in 8.1.0 the Intent.ACTION_CLOSE_SYSTEM_DIALOGS broadcast is not calling.I am using below implementation.
public class HomeWatcher {
static final String TAG = "hg";
private Context mContext;
private IntentFilter mFilter;
private OnHomePressedListener mListener;
private InnerRecevier mRecevier;
public HomeWatcher(Context context) {
mContext = context;
mFilter = new IntentFilter();
mFilter.addAction(Intent.ACTION_CLOSE_SYSTEM_DIALOGS);
mFilter.addAction("");
}
public void setOnHomePressedListener(OnHomePressedListener listener) {
mListener = listener;
mRecevier = new InnerRecevier();
}
public void startWatch() {
if (mRecevier != null) {
mContext.registerReceiver(mRecevier, mFilter);
}
}
public void stopWatch() {
if (mRecevier != null) {
mContext.unregisterReceiver(mRecevier);
}
}
class InnerRecevier extends BroadcastReceiver {
final String SYSTEM_DIALOG_REASON_KEY = "reason";
final String SYSTEM_DIALOG_REASON_GLOBAL_ACTIONS = "globalactions";
final String SYSTEM_DIALOG_REASON_RECENT_APPS = "recentapps";
final String SYSTEM_DIALOG_REASON_HOME_KEY = "homekey";
#Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (action.equals(Intent.ACTION_CLOSE_SYSTEM_DIALOGS)) {
String reason = intent.getStringExtra(SYSTEM_DIALOG_REASON_KEY);
if (reason != null) {
Log.e(TAG, "action:" + action + ",reason:" + reason);
if (mListener != null) {
if (reason.equals(SYSTEM_DIALOG_REASON_HOME_KEY)) {
mListener.onHomePressed();
} else if (reason.equals(SYSTEM_DIALOG_REASON_RECENT_APPS)) {
mListener.onHomeLongPressed();
}
}
}
}
}
}
}
and in class, I am calling using below code.
HomeWatcher mHomeWatcher = new HomeWatcher(this);
mHomeWatcher.startWatch();
Please help!.
Edited----
The above code is working properly in normal flow but when the screen pinning is set(ON) then it's not working. Even i am not getting any event like KeyUp, KeyDown

Answer 1

com.android.systemui package will be the foreground app when you click recent app button, so find the foreground running apps and launch your page if foreground running app is 'com.android.systemui'.

Answer 2

HomeWatcher mHomeWatcher = new HomeWatcher(this);
mHomeWatcher.setOnHomePressedListener(new OnHomePressedListener() {
#Override
public void onHomePressed() {
// do something here...
}
#Override
public void onHomeLongPressed() {
}
});
mHomeWatcher.startWatch();

Log.i("key pressed", String.valueOf(event.getKeyCode()));
return super.dispatchKeyEvent(event);
}`
