Redmi 2中的Internet處於關閉狀態時未調用Android BroadcastReceiver的onReceive

Question

當我的互聯網連接關閉時，廣播接收器不起作用，但是當我的互聯網連接時，廣播接收機可以正常工作。

我已在我的應用程序的安全設置中啟用了自動啟動。 我還重新啟動了Redmi / note3，在某些redmi2中，它工作正常。

無論是離線還是在線，但在某些redmi2手機中，它完全無法正常工作

顯然，在檢查Internet連接時，應檢查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
    }
