当我点击通知推送时，特定活动无法打开（需要真正的帮助）

Question

Not opening specific activity on notification click when the app is in background/not running

The notification-click starts specified activity only when the app is opened up and the notification-click is performed. If the app is in background/not running and the notification-click is performed, the application's MainActivity opens up. In short, it is like the app opens normally following the activity stack instead of opening the specified activity in the PendingIntent.

I saw a solution similar to this problem in this forum did not help unfortunately

MyApplication

public class MyApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();

        OneSignal.startInit(this).setNotificationOpenedHandler(new ExampleOpenHandler())
                .autoPromptLocation(true).init();

    }

    private class ExampleOpenHandler implements OneSignal.NotificationOpenedHandler {

        @Override
        public void notificationOpened(OSNotificationOpenResult result) {

            JSONObject data=result.notification.payload.additionalData;

            Intent intent = new Intent(getApplicationContext(),SecondActivity.class);
            intent.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT | Intent.FLAG_ACTIVITY_NEW_TASK);

            try{

                intent.putExtra("datam",data.getString("1"));
            }catch (JSONException e) {
                e.printStackTrace();

            }
            startActivity(intent);
        }
    }
}

SecondActivity

public class SecondActivity extends AppCompatActivity {

    TextView dataview;
    String getdata;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_second);

        getdata = getIntent().getExtras().getString("datam");

        dataview = (TextView) findViewById(R.id.dataview);
        dataview.setText(getdata);
    }
}

To start an activity that includes a back stack of activities, you need to create an instance of TaskStackBuilder and call addNextIntentWithParentStack(), passing it the Intent for the activity you want to start.
