我的一些用户遇到以下错误：

该应用程序需要互联网才能完成最基本的功能，我不认为用户已使用root或类似内容删除了权限。

此外，此错误是通过我自己的错误报告工具发送给我的。我已使用已注册的错误进行上传，此时该权限已可用。

对于有错误的android版本的设备型号没有限制。

清单的一部分示例：

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

感谢任何线索，

提前致谢。

Answer 1

我有这个代码可以提供帮助。这将只询问您的应用程序所需的权限

 public static boolean hasPermissions(Context context, String... permissions)
{
    if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null && permissions != null)
    {
        for (String permission : permissions)
        {
            if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED)
            {
                return false;
            }
        }
    }
    return true;
}

在你的onCreate

中添加此代码

 int PERMISSION_ALL = 1;
    String[] PERMISSIONS = {Manifest.permission.READ_CONTACTS, Manifest.permission.WRITE_CONTACTS, Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_SMS, Manifest.permission.CAMERA};

    if (!hasPermissions(this, PERMISSIONS)) {
        ActivityCompat.requestPermissions(this, PERMISSIONS, PERMISSION_ALL);
    }

Answer 2

这可能会对你有所帮助

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

java.lang.SecurityException：Permission denied（缺少INTERNET权限？）
