android - 网络更改广播接收器未执行

Question

我需要一个广播接收器名称“NetworkReciver.java”，它应该在 Internet 连接或断开连接时执行。但它没有执行。

list 权限

 <uses-permission android:name="android.permission.INTERNET" />
 <uses-permission android:name="com.android.alarm.permission.SET_ALARM" />
 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />


 <receiver android:name=".NetworkReciever" >
    <intent-filter>
       <action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
    </intent-filter>
</receiver>

在MainActivity.java中请求权限

String[] permissionsRequired = new String[]{Manifest.permission.SET_ALARM,
     Manifest.permission.INTERNET,
     Manifest.permission.ACCESS_NETWORK_STATE,};
     // Since these are Normal Permissions
     ActivityCompat.requestPermissions(this, permissionsRequired, 1);

网络接收者.java:

public class NetworkReciever extends BroadcastReceiver 
{

         @Override
         public void onReceive(Context context, Intent intent)
         {
                Log.i("KAMLESH", "Network REceiver Alarm Set in Hair Style");
         }
}

Answer 1

你必须像 registerReceiver(new NetworkReciever()); 一样注册 NetworkReciever 这个广播接收器。在任何 Activity 中
