目前,我正在开发Truecaller等阻塞应用程序.
我需要什么
I want to detect the incoming calls even my app is removed from the
recent apps list.
Manifest.xml代码
<receiver android:name=".PhoneStateReceiver">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
</receiver>
我的广播接收器代码
@Override
public void onReceive(Context context,Intent intent) {
//my call blocking code
}
我的问题
My BroadcastReceiver wont work in the background as if I removed from
the recent apps list.
我的完整清单代码在这里
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

我应该使用服务还是别的什么？
更新：
有了Suraj的答案,我在接收器中尝试过这个标签
android:enabled="true"
android:exported="true"
android:process=":anotherProcess"
它适用于kitkat ..但不适用于棒棒糖..
更新问题：
Incase如果不可能保持活动广播接收器即使我的应用程序关闭,我如何检测来电？
任何人给出详细的答案
解决方法
在这里,我们通知接收方服务.
所以做一个服务类
public class MyService extends Service {
@Nullable
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public int onStartCommand(Intent intent,int flags,int startId) {
new CountDownTimer(100000,4000)
{
@Override
public void onTick(long millisUntilFinished) {
sendBroadcast(new Intent("fromservice"));
}
@Override
public void onFinish() {
}
}.start();
return START_STICKY;
}
}
现在做一个接收器
public class MyReceiver extends WakefulBroadcastReceiver {
@Override
public void onReceive(final Context context,Intent intent) {
Toast.makeText(context,"inside receiver",Toast.LENGTH_SHORT).show();
}
}
现在从主要活动开始服务
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
startService(new Intent(this,MyService.class));
}
}
在清单中声明接收者和服务如下
<receiver android:name=".MyReceiver"
android:process=":jk"
android:enabled="true"
android:exported="true">
<intent-filter>
<action android:name="fromservice"/>
</intent-filter>
</receiver>
<service android:name=".MyService"
android:process=":ff"
android:enabled="true"
android:exported="true" />
<uses-permission android:name="android.permission.WAKE_LOCK"/>
什么是倒计时器？
倒计时器可以理解为一种具有方法的迭代
onTick()和onFinish()
onTick()在CountDownTimer构造函数中给出的间隔(持续时间)之后被多次调用.
当longTimeInFuture已经存在时,onFinish()最后被调用(只有一次).
