我试图在我的应用程序中获取通知触发器，每当用户进行新的呼叫时。我在我的活动中注册接收器，并在onDestroy()方法中销毁它。以下是注册的代码片段：
registerReceiver(inComingCall = new IncomingCall(),new IntentFilter("android.intent.action.PHONE_STATE"));
NEW_OUTGOING_CALL或BOOT_COMPLETED，您仍然可以在清单中使用。但是，在应用程序上下文中实现运行时是一个好习惯。我希望我的PHONE_STATE始终准备好接收来电和去电，即使在每次重新启动时...<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

在上面的 manifest.xml 文件中，我没有放置 WRITE_EXTERNAL_STORAGE 和 READ_EXTERNAL_STORAGE。因为我在运行时实现了它，所以它会被 Android Studio 自动插入。
这是我的 OnBoot 接收器：

}
}
@Override
public int onStartCommand(Intent intent, int flags, int startId)
{
Log.d("WatchMan : ", "\nmCallBroadcastReceiver Listening....");
//return super.onStartCommand(intent, flags, startId);

@Override

}
现在，在调用之前将电话号码插入到sqlite数据库表中;这样您就可以从CatchNumbers.java服务中读取它，并对进出的数字执行任何操作。希望它能帮助你或其他人。
Sandhya Sasane的解决方案在Android 9模拟器上对我有效，可以接收到BOOT_COMPLETED通知（无论是通过“adb”强制执行还是重新启动模拟器）。
但是，在真实设备华为P-Smart上，配备EMUI 9.1.0.119，从未发生过 :(
以上的答案似乎都对我不起作用。 这是我的解决方案，但是使用 Kotlin。请粘贴以下代码部分，并根据您的应用程序更改必要的详细信息。
在 MainActivity 的 onCreate 方法之后：
override fun onStart() {
super.onStart()
var intentfilter1: IntentFilter = IntentFilter("com.spotify.music.playbackstatechanged")
intentfilter1.addCategory(Intent.CATEGORY_DEFAULT)
registerReceiver(mreceiver, intentfilter1)
}
override fun onStop() {
super.onStop()
unregisterReceiver(mreceiver)
}
在 onCreate 方法中：
mreceiver = SpotifyBroadcastReceiver()
在 MainActivity 的 onCreate 方法之前：
lateinit var mreceiver: SpotifyBroadcastReceiver
主清单文件
<receiver android:name=".SpotifyBroadcastReceiver" //name of the broadcast receiver class
android:permission="android.permission.RECEIVE_BOOT_COMPLETED"
android:enabled="true"
android:exported="true">
<intent-filter>
<action android:name="com.spotify.music.playbackstatechanged" /> //Things required by my broadcast receiver class
</intent-filter>
</receiver>
如果我漏掉了什么或者你需要与代码片段相关的其他信息，请告诉我。
附言：我也是 Kotlin 的新手...我只是分享了对我有用的内容。它可能适用于你的配置，也可能不适用，所以祝你编码愉快！
我也遇到过这种问题，但是我找到了更好的解决方案：
@BroadcastReceiverActions({"android.intent.action.SCREEN_ON", "android.intent.action.SCREEN_OFF",
"android.intent.action.DREAMING_STARTED", "android.intent.action.DREAMING_STOPPED",
"android.intent.action.ACTION_POWER_DISCONNECTED", "android.intent.action.ACTION_POWER_CONNECTED",
"android.net.conn.CONNECTIVITY_CHANGE"})
public class MyReceiver extends BroadcastReceiver {
public MyReceiver() {
super();
}
@Override
public void onReceive(Context context, Intent intent) {
Session.getGlobalReceiverCallBack(context, intent);
//Log.e("dfd", "" + intent.getAction());
}
}
public class AppController extends Application {
private BroadcastReceiver receiver;
MyReceiver mR;
@Override
public void onCreate() {
super.onCreate();
mR = new MyReceiver();
receiver = DynamicReceiver.with(mR)
.register(this);
}
}
public class MainActivity extends AppCompatActivity implements GlobalReceiverCallBack {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Session.setmGlobalReceiverCallback(this);
}
@Override
public void onCallBackReceived(Context context, Intent intent) {
Toast.makeText(context, "" + intent.getAction(), Toast.LENGTH_LONG).show();
}
}
