我正在开发一个 Android 应用程序,我要求在其中实现通话记录,我已经通过 SO 并找到了一个解决方案,当我的应用程序打开时它工作正常。如果我关闭我的应用程序或从最近的应用程序中清除它,通话记录不起作用。尝试在 Google 和 SO 中搜索,但没有运气。我在这里发布我的代码,有人可以帮助我获得解决方案。

CallreCorder 服务类:

public class TService extends Service {
MediaRecorder recorder;
File audiofile;
String name, phonenumber;
String audio_format;
public String Audio_Type;
int audioSource;
Context context;
private Handler handler;
Timer timer;
Boolean offHook = false, ringing = false;
Toast toast;
Boolean isOffHook = false;
private boolean recordstarted = false;

private static final String ACTION_IN = "android.intent.action.PHONE_STATE";
private static final String ACTION_OUT = "android.intent.action.NEW_OUTGOING_CALL";
private CallBr br_call;




@Override
public IBinder onBind(Intent arg0) {
    // TODO Auto-generated method stub
    return null;
}

@Override
public void onDestroy() {
    Log.d("service", "destroy");

    super.onDestroy();
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    // final String terminate =(String)
    // intent.getExtras().get("terminate");//
    // intent.getStringExtra("terminate");
    // Log.d("TAG", "service started");
    //
    // TelephonyManager telephony = (TelephonyManager)
    // getSystemService(Context.TELEPHONY_SERVICE); // TelephonyManager
    // // object
    // CustomPhoneStateListener customPhoneListener = new
    // CustomPhoneStateListener();
    // telephony.listen(customPhoneListener,
    // PhoneStateListener.LISTEN_CALL_STATE);
    // context = getApplicationContext();

    final IntentFilter filter = new IntentFilter();
    filter.addAction(ACTION_OUT);
    filter.addAction(ACTION_IN);

使用START_STICKY作为 onStartCommand() 的返回参数,所以当你杀死你的应用程序时,它将重新启动服务

作为参考,您可以查看 android 开发者指南
