i have to build an application in which a functionality requires to detect Navigation Buttons Clicks like: Back,Home & Recent App Button and then performing some functionality via Service.
create Receiver in Service Class:
class InnerReceiver extends BroadcastReceiver {
final String SYSTEM_DIALOG_REASON_KEY = "reason";
final String SYSTEM_DIALOG_REASON_RECENT_APPS = "recentapps";
final String SYSTEM_DIALOG_REASON_HOME_KEY = "homekey";
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(Intent.ACTION_CLOSE_SYSTEM_DIALOGS)) {
String reason = intent.getStringExtra(SYSTEM_DIALOG_REASON_KEY);
if (reason != null) {
if (reason.equals(SYSTEM_DIALOG_REASON_HOME_KEY)) {
// Home Button click
} else if (reason.equals(SYSTEM_DIALOG_REASON_RECENT_APPS)) {
// RecentApp or Overview Button click
}
}
}
}
}
then Register Broadcast Receiver in Service onStartCommand() method:
mReceiver = new InnerReceiver();
IntentFilter mFilter = new IntentFilter(Intent.ACTION_CLOSE_SYSTEM_DIALOGS);
registerReceiver(mReceiver, mFilter);
and Unregister Receiver in onDstroy() Method:
unregisterReceiver(mReceiver);
