如何触发广播接收器，当我开启/关闭移动蜂窝数据（手机上网） [英] How to trigger BroadcastReceiver when I turn on/off Mobile Cellular Data(Mobile Internet)

问题描述

我想知道如何触发的广播接收器如果我的开启/关闭移动蜂窝数据即可。我已经注册广播接收器和是如果我开启/关闭无线网络工作正常，但如果我打开/关闭蜂窝数据没有广播触发。任何人都可以请帮我这个？

这是我的code。

下面我注册的广播接收器在 Manifest.file

 ＆lt;接收机器人：名字=com.servicesandroid.NetworkCheckReceiver＆GT;
            ＆所述;意图滤光器＆gt;
                ＆lt;作用机器人：名字=android.net.conn.CONNECTIVITY_CHANGE/＆GT;
            ＆所述; /意图滤光器＆gt;
        ＆LT; /接收器＆GT;
 

清单权限

 ＆LT;使用许可权的android：NAME =android.permission.ACCESS_NETWORK_STATE/＆GT;
    ＆LT;使用许可权的android：NAME =android.permission.INTERNET对/＆GT;
 

下面是我的广播接收器类。

 公共类NetworkCheckReceiver扩展广播接收器{    @覆盖
    公共无效的onReceive（上下文的背景下，意图意图）{
        // TODO自动生成方法存根
        Toast.makeText（背景下，已启动，Toast.LENGTH_SHORT）.show（）;
         Log.d（应用程序，网络连通性的变化）;
    }}
 

解决方案

您需要指定相应的权限和做要紧如下所述：

在清单权限：

 ＆LT;使用许可权的android：NAME =android.permission.INTERNET对/＆GT;
＆LT;使用许可权的android：NAME =android.permission.ACCESS_NETWORK_STATE/＆GT;
＆LT;使用许可权的android：NAME =android.permission.ACCESS_WIFI_STATE/＆GT;
 

在清单的接收声明：

 ＆lt;接收
        机器人：名字=。NetworkCheckReceiver
        ＆GT;
        ＆所述;意图滤光器＆gt;
            ＆lt;作用机器人：名字=android.net.conn.CONNECTIVITY_CHANGE/＆GT;
        ＆所述; /意图滤光器＆gt;
    ＆LT; /接收器＆GT;
 

NetworkCheckReceiver类文件：

 公共类NetworkCheckReceiver扩展广播接收器{    @覆盖
    公共无效的onReceive（上下文的背景下，意图意图）{
        如果（intent.getAction（）。等于（ConnectivityManager.CONNECTIVITY_ACTION））{
            Log.d（NetworkCheckReceiver，NetworkCheckReceiver援引...）;
            布尔noConnectivity = intent.getBooleanExtra（
                    ConnectivityManager.EXTRA_NO_CONNECTIVITY，FALSE）;            如果（！noConnectivity）{
                Log.d（NetworkCheckReceiver，连接）;
            }
            其他
            {
                Log.d（NetworkCheckReceiver，断开连接）;
            }
        }
    }}
 

注意：

请确保您有工作的移动蜂窝数据连接。如果你没有上网包，你只要开启/关闭该接收器将不会触发。你肯定的需要有工作连接以测试。

I want to know how to trigger BroadcastReceiver if I turn on/off mobile cellular data. I already registered BroadcastReceiver and it is working fine if I turn on/off wifi but if I turn on/off cellular data no broadcast trigger. can anyone please help me about this?

Here is my code.

Here I register BroadcastReceiver in Manifest.file

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

Manifest permissions

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

Here is my BroadcastReceiver class.

public class NetworkCheckReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub
        Toast.makeText(context, "Started", Toast.LENGTH_SHORT).show();
         Log.d("app","Network connectivity change");
    }

}

解决方案

You need to specify appropriate permissions and do the needful as mentioned below:

Permissions in manifest:

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

Receiver declaration in manifest:

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

NetworkCheckReceiver class file:

public class NetworkCheckReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(ConnectivityManager.CONNECTIVITY_ACTION)) {
            Log.d("NetworkCheckReceiver", "NetworkCheckReceiver invoked...");


            boolean noConnectivity = intent.getBooleanExtra(
                    ConnectivityManager.EXTRA_NO_CONNECTIVITY, false);

            if (!noConnectivity) {
                Log.d("NetworkCheckReceiver", "connected");
            }
            else
            {
                Log.d("NetworkCheckReceiver", "disconnected");
            }
        }
    }

}

Note:

Make sure you have working mobile cellular data connection. This receiver won't trigger if you don't have internet pack and you just switching on/off. You surely need to have working connection to test.
