如何在每次用户打开应用程序时调用BroadcastReciver

Question

我希望有一个BroadcastReciver在应用程序启动时调用！（例如当用户打开电报应用程序时我的BroadcastResiver调用） 我有这个课程，呼叫每个'call_period＆＃39; millseconds：

public class StartupReceiver extends BroadcastReceiver {
static final String TAG = "SR";

final int startupID = 1111111;
private static int call_period=5000;
Database db;


@Override
public void onReceive(Context context, Intent intent) {
    db=new Database(context);
    db.open();
    call_period=db.getChechTime();
    db.close();
    final AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
    try{

        Intent i7 = new Intent(context, CheckRunningApplicationReceiver.class);
        PendingIntent ServiceManagementIntent = PendingIntent.getBroadcast(context,startupID, i7, 0);
        alarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME,SystemClock.elapsedRealtime(), call_period, ServiceManagementIntent);


    } catch (Exception e) {
        Log.i(TAG, "Exception : "+e);
    }

}
public void setCallPeriod(int millsec){
    call_period=millsec;

}

}

如何在应用程序启动时更改它以进行调用？
