Tôi nghĩ bạn nên thêm một số logic để làm cho nó hoạt động, có lẽ điều này có thể giúp:
Ví dụ: tôi có Màn hình Splash (Trình khởi chạy và MAIN) của APP:
public class SplashScreen extends AppCompatActivity {
private final int TIME_OUT = 2000;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash_screen);
// Suscribirse al tema Notificaciones
FirebaseMessaging.getInstance().subscribeToTopic("NOTA");
if (getIntent().getExtras() != null) {
if (getIntent().getExtras().size()>1){
Intent home_activity = new Intent(getApplicationContext(), Home.class);
home_activity.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
if (getIntent().getExtras() != null) {
for (String key : getIntent().getExtras().keySet()) {
String value = "" + getIntent().getExtras().getString(key);
Log.d("TAG", key + "=" + value);
switch (key) {
case "url":
home_activity.putExtra("url", value);
break;
}
}
}
startActivity(home_activity);
finish();
}else{
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
try {
Intent home_activity = new Intent(getApplicationContext(), Home.class);
home_activity.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(home_activity);
finish();
} catch (Exception ex) {
ex.printStackTrace();
}
}
}, TIME_OUT);
}
} else {
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
try {
Intent home_activity = new Intent(getApplicationContext(), Home.class);
home_activity.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(home_activity);
finish();
} catch (Exception ex) {
ex.printStackTrace();
}
}
}, TIME_OUT);
}
}
}
Và trong FirebaseService của tôi, tôi đã làm như sau:
public class FCMessagingService extends FirebaseMessagingService {
private final String TAG = "PUSH";
private String body = "";
private static String _url = "";
private static int numMessage = 0;
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
String from = remoteMessage.getFrom();
Log.d(TAG, "Mensaje recibido de: " + from);
if (remoteMessage.getNotification() != null) {
Log.d(TAG, "Notificación: " + remoteMessage.getNotification().getBody());
if (remoteMessage.getData().size() > 0) {
Log.d(TAG, "Data: " + remoteMessage.getData());
try {
JSONObject data = new JSONObject(remoteMessage.getData());
String url = data.getString("url");
Log.d(TAG, "onMessageReceived: \n" + "Extra Information: " + url);
this._url = url;
Log.d("_URL",_url);
mostrarNotificacion(remoteMessage.getNotification().getTitle(), remoteMessage.getNotification().getBody());
mensaje(url, remoteMessage.getNotification().getTitle(), remoteMessage.getNotification().getBody());
} catch (JSONException e) {
e.printStackTrace();
}
}
}
}
private void mensaje(String url, String title, String body){
boolean acti = Util.comprobarActivityALaVista(getApplicationContext(), "com.dev.android.subagan.MainActivity");
if(acti){
Intent imain = new Intent(MainActivity.URL);
imain.putExtra("key_url",url);
imain.putExtra("key_title",title);
imain.putExtra("key_body",body);
LocalBroadcastManager.getInstance(getApplicationContext()).sendBroadcast(imain);
}else{
Intent ihome = new Intent(Home.URL);
ihome.putExtra("key_url",url);
ihome.putExtra("key_title",title);
ihome.putExtra("key_body",body);
LocalBroadcastManager.getInstance(getApplicationContext()).sendBroadcast(ihome);
}
}
private void mostrarNotificacion(String title, String body) {
final int NOTIFICATION_ID = 3000;
Intent intent = new Intent(this, MainActivity.class);
intent.putExtra("url",_url);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,PendingIntent.FLAG_UPDATE_CURRENT | PendingIntent.FLAG_ONE_SHOT );
Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle(title)
.setContentText(body)
.setAutoCancel(true)
.setSound(soundUri)
.setTicker(body)
.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificationBuilder.build());
}
}
