私はあなたがそれを機能させるためにいくつかのロジックを追加する必要があると思います、これはおそらく助けることができます：
たとえば、APPのスプラッシュスクリーン（ランチャーとメイン）があります。
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);
}
}
}
そして私のFirebaseServiceで私は次のことをしました：
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());
}
}
