Android packageInfo.requestedPermissions返回不正确的权限

这是我的AndroidManifest.xml，该文件中有8个权限

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    </application>
</manifest>

但是结果不正确，我获得了以下权限，android.permission.WRITE\u EXTERNAL\u存储丢失！！！，为什么?

[编辑]添加android sdk版本和手机状态

ext {
    compileSdkVersion = 28
    minSdkVersion = 17
    targetSdkVersion = 28
    buildToolsVersion = '28.0.3'
}

我想这个问题已经在这篇文章中得到了回答：

你是否申请/批准了那项危险的许可？如果设备运行的是Android 6.0 API级别23或更高，且应用程序的targetSdkVersion为23或更高，则在安装时不会通知用户任何应用程序权限。你的应用程序必须要求用户在运行时授予危险的权限。我以前没有遇到过这种情况，但它可能正在崩溃同一权限组中的权限，因为将授予另一个权限组？您可以通过添加一些其他权限来测试这一点。您误解了这个问题。问题不是运行时权限或访问被拒绝。这是因为packageInfo对象返回的权限列表不完整。

ext {
    compileSdkVersion = 28
    minSdkVersion = 17
    targetSdkVersion = 28
    buildToolsVersion = '28.0.3'
}

public  boolean isStoragePermissionGranted() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        if (checkSelfPermission(android.Manifest.permission.WRITE_EXTERNAL_STORAGE)
                == PackageManager.PERMISSION_GRANTED) {
            Log.v(TAG,"Permission is granted");
            return true;
        } else {

            Log.v(TAG,"Permission is revoked");
            ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
            return false;
        }
    }
    else { //permission is automatically granted on sdk<23 upon installation
        Log.v(TAG,"Permission is granted");
        return true;
    }
}

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if(grantResults[0]== PackageManager.PERMISSION_GRANTED){
        Log.v(TAG,"Permission: "+permissions[0]+ "was "+grantResults[0]);
        //resume tasks needing this permission
    }
}
