我是新来的通知。我没有找到任何帮助，请帮助我。提前谢谢。我必须在Android应用程序中显示通知但它不会打电话给我的广播接收器，虽然我添加清单中的权限
<Service android:name="com.example.tajgroup.newsapplication.service.NotificationService"
android:enabled="true"/>
<receiver android:name=".reciever.UpdateReciever">
<intent-filter>
<action android:name="android.net.com.CONNECTIVITY_CHANGE" />
</intent-filter>
/></receiver>
and my NotificationService and UpdateReciever are
public class UpdateReciever extends BroadcastReceiver {
ConnectivityManager connectivityManager;
NetworkInfo networkInfo;
String dateString;
public static NotificationManager mNotificationManager;
public static int SIMPLE_NOTFICATION_ID;

serviceintent = new Intent(context, NotificationService.class);
context.startService(serviceintent);
context.stopService(serviceintent);
}
}
// Check for network availability
private boolean isNetworkAvailable(Context context) {
ConnectivityManager connectivityManager = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetworkInfo = connectivityManager
.getActiveNetworkInfo();

可能需要SelfCheckPermission。您正在使用什么API级别？
