手机收到通知后如何在没有任何用户交互的情况下自动打开 Android 应用程序

Question

我搜索如何在没有用户交互的情况下自动打开 Android 应用程序一旦应用程序收到 FCM，我知道逻辑会将它放在方法 onMessageReceived 上，我不知道应用程序将如何在没有用户按下通知的情况下打开活动，应用程序自动打开

Answer 1

in your methods onMessageReceived() write somting like

Intent dialogIntent = new Intent(TrackingService.this, RequestView.class);
                            dialogIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                            startActivity(dialogIntent);

here is my full code in github but the start activity method will be good but take care you have to add the FLAG_ACTIVITY_NEW_TASK as i did in the above code to open activity when the app is close
