该应用程序需要互联网才能完成最基本的功能，我认为用户不会使用root或类似内容删除权限。

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：

<manifest xmlns:android="http://schemas.android.com/apk/res/android">

    <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。

这会对你有所帮助。在onCreate方法中写下以下内容

 ArrayList<Contact> selectedContacts = data.getParcelableArrayListExtra("SelectedContacts");

并获得此方法

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);
    }

应用程序只会询问应用程序需要的权限，也只需要一次。如果它起作用，请告诉我。它对我有用

Answer 2

HttpUrlConnection请求还需要android.permission.ACCESS_NETWORK_STATE。您是否也在清单中列出了此权限？

请发布您的清单文件，以便我们可以看到android.permission.ACCESS_NETWORK_STATE和android.permission.INTERNET都列出时没有任何拼写，大小写，语法错误。

如果用户已植根其Android设备并修改了权限，则也会出现此问题。你怎么知道用户没有植根设备？你能在自己的设备上重现这个问题吗？
