如何在 Android 10 的内部存储中创建我的自定义目录（文件夹）并存储我的数据？

Question

I am perfectly able to generate a PDF and store it in my custom made folder in Android SDK's version=<28 but as of Android 10

 customFolder = new File(getExternalStorageDirectory() + File.separator + "TimingNotezz");
 customFolder.mkdirs();

customFolder.mkdirs() is false which means folder is not created, so

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) 
{
    //I want to implement the code to create and store contents in a custom directory specifically for 
    // Android 10 here
} 

How can I do that? Thanks in advance. I would love to have different suggestions.

You can use Intent.ACTION_OPEN_DOCUMENT_TREE to let the user choose a storage location. Then after that create your "TimingNotezz" folder in it using storage access framework. Also your file you should create using saf.
