Question

当我的互联网连接关闭时，广播接收器不起作用，但是当我的互联网连接时，它的工作正常。

我已在我的应用的安全设置中启用了自动启动功能。我也重新启动了Redmi / note3，在一些redmi2中它运行正常。

无论是离线还是在线，但在某些redmi2手机中它完全无法正常工作

显然，在检查互联网连接时，您应该检查activeNetwork的isConnected（）方法。

ConnectivityManager connectivityManager = (ConnectivityManager) ctx.getSystemService(Context.CONNECTIVITY_SERVICE);
     NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
    if (networkInfo != null && networkInfo.isAvailable() && networkInfo.isConnected()){
        // Network Active
    }else{
        // Network Inactive
    }

在redmi 2中互联网关闭时，Android BroadcastReceiver的onReceive没有被调用
