android studio app just says error in network connection

javaandroid

提问by james

I have created a login and register system, when ever I try to login, register, change password or reset password the app just says "Error In Network Connection".

我创建了一个登录和注册系统，当我尝试登录、注册、更改密码或重置密码时，应用程序只会显示“网络连接错误”。

I am using strong internet connection, could you please advise as I have tried to on WI-FI and 4G, however it still says the same error.

我正在使用强大的互联网连接，您能否在我尝试使用 WI-FI 和 4G 时提供建议，但它仍然显示相同的错误。

In your manifest file add

在您的清单文件中添加

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

回答by Kerbstomp

I'm not 100% if this is your problem because you did not post your manifest file but I've encountered this problem before and to fix it add the permission to your manifest file.

如果这是你的问题，我不是 100%，因为你没有发布你的清单文件，但我以前遇到过这个问题，并修复它添加到你的清单文件的权限。

  1. check application on different devices

  2. check for connection with following method

    public static boolean isNetworkConnected(Context context) {
    ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
    return networkInfo != null && networkInfo.isConnected();
}
  1. 检查不同设备上的应用程序

  2. 使用以下方法检查连接

    public static boolean isNetworkConnected(Context context) {
    ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
    return networkInfo != null && networkInfo.isConnected();
}

I had a similar problem. Check that your mobile device is connected to the internet. That was the problem for me. No internet connection on the mobile device.

我有一个类似的问题。检查您的移动设备是否已连接到互联网。这就是我的问题。移动设备上没有互联网连接。
