Question

我的清单里有一个接收器。

<receiver
    android:name="com.deviceinventory.StartAppAtBootReceiver"
    android:enabled="true"
    android:exported="false"
    android:label="StartMyServiceAtBootReceiver" >
    <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
</receiver>

我的com.deviceinventory.StartAppAtBootReceiver onReceive（）是

public void onReceive(Context context, Intent intent) {    
   if (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())) {
        Intent startUpIntent = new Intent(context, StartUpActivity.class);
        startUpIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(startUpIntent);
    }

由于StartUpActivity使用互联网，所以我想在互联网连接可用后启动此活动。

目前它在互联网连接建立之前的某个时间开始。

我不知道如何修改manifest和BroadCastReceiver

中的接收器

Answer 1

为此，您需要再添加一个Receiver来检查Internet连接是启用还是禁用，启用后，您可以启动要运行的bootReceiver或Any Activity。

public class NetworkInfoReceiver extends BroadcastReceiver {

@Override
public void onReceive(final Context context, final Intent intent) {
try {
    /***
     * Here we need to check its running perfectly means this receiver
     * call when net is off/on. You should have to check
     * */
    final ConnectivityManager conMngr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);

    // Check if we are connected to an active data network.
    final NetworkInfo activeNetwork = conMngr.getActiveNetworkInfo();
    final boolean isConnected = activeNetwork != null && activeNetwork.isConnectedOrConnecting();

    if (isConnected) {
    /**
     * Start service/receiver/activity here.
     * */

    } else {
    /**
     * Stop service/receiver/activity here.
     * */
    }
} catch (final Exception e) {
}
}
}

然后将此接收器添加到AndroidManifest.xml文件中。

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

Answer 2

您可以尝试编辑意图过滤器。现在，当设备完全启动时，你的收音机会响应。改变它以在连接性改变时响应它......

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

希望这段代码可以帮到你。

Answer 3

@Hemant你需要检查onReceive是否满足两个条件才能启动服务。

 public void onReceive(Context context, Intent intent) {
ConnectivityManager cm = (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
      if(intent.equals(Intent.ACTION_BOOT_COMPLETE) && wifiManager.isWifiEnabled()){
      //start your service
       }
}

在android中的接收器显示两个动作
