android 怎么申请下面这个权限 Rejected access to app-private dir on F

要申请访问应用程序私有目录的权限，需要在 AndroidManifest.xml 文件中声明以下权限：

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

这将允许您的应用程序访问外部存储器，并且可以在应用程序运行时创建、读取、写入和删除文件。请注意，这个权限是需要在运行时动态申请的，使用方法如下：

if (ContextCompat.checkSelfPermission(thisActivity, Manifest.permission.WRITE_EXTERNAL_STORAGE)
        != PackageManager.PERMISSION_GRANTED) {
    // Permission is not granted
    // Should we show an explanation?
    if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity,
            Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
        // Show an explanation to the user *asynchronously* -- don't block
        // this thread waiting for the user's response! After the user
        // sees the explanation, try again to request the permission.
    } else {
        // No explanation needed; request the permission
        ActivityCompat.requestPermissions(thisActivity,
                new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
                MY_PERMISSIONS_REQUEST_WRITE_EXTERNAL_STORAGE);
        // MY_PERMISSIONS_REQUEST_WRITE_EXTERNAL_STORAGE is an
        // app-defined int constant. The callback method gets the
        // result of the request.
    }
} else {
    // Permission has already been granted
}

此代码演示了如何在运行时动态请求 WRITE_EXTERNAL_STORAGE 权限。如果权限已经被授予，代码将执行相应的操作，否则代码将请求权限并等待用户响应。请注意，这个代码只是示例，您需要将其适当地集成到您的应用程序中。
