第一步：

manifest中添加

<uses-permission android:name="android.permission.READ_CALL_LOG"/>

<uses-permission android:name="android.permission.WRITE_CALL_LOG"/>

第二步：在####Activity的oncreate中添加：

private void checkCallLogNeedPermissions() {

          if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_CALL_LOG)

                    != PackageManager.PERMISSION_GRANTED) {

                ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_CALL_LOG}, 100);

            }

    }

在调用的service中添加：

Notification notification =new Notification.Builder(getApplicationContext(),CHANNEL_ID).build();

startForeground(1, notification);
