如何在android“ Pie”中关闭应用程序时检测电话状态广播接收者

Question

我正在尝试使用TelephoneManager类并使用作业调度程序来获取电话状态，我已经为onCallStateChangeListener（）分配了侦听器...但仍然是android 9“ Pie”杀死了像我这样的所有后台任务侦听器和jobScheduler！所以当我的应用程序完全关闭时，我该如何解决此问题并获得电话状态！

注意：我尝试了类似Truecaller的应用程序，并且在关闭应用程序后可以正常使用！我如何在我的应用程序上得到类似的行为？

MainActivity.java

import android.app.job.JobInfo;
import android.app.job.JobScheduler;
import android.content.ComponentName;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {
    private static final String TAG = "MainActivity";
    private static final int JOB_ID = 123;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        scheduleJob();
    }

    public void scheduleJob() {
        ComponentName componentName = new ComponentName(this, ExampleJobService.class);
        JobInfo info = new JobInfo.Builder(JOB_ID , componentName)
                .setPersisted(true)
                .setPeriodic(15 * 60 * 1000)
                .build();

        JobScheduler scheduler = (JobScheduler) getSystemService(JOB_SCHEDULER_SERVICE);
        int resultCode = scheduler.schedule(info);
        if (resultCode == JobScheduler.RESULT_SUCCESS) {
            Log.d(TAG, "Job scheduled");
        } else {
            Log.d(TAG, "Job scheduling failed");
        }
    }

    public void cancelJob() {
        JobScheduler scheduler = (JobScheduler) getSystemService(JOB_SCHEDULER_SERVICE);
        scheduler.cancel(123);
        Log.d(TAG, "Job cancelled");
    }
