Android java: request multiple permission READ_EXTERNAL_STORAGE & WRITE_EXTERNAL_STORAGE

Minimum API 24 (Android 7.0) 

Note:

• Beginning with Android 4.4 (API level 19) it's no longer necessary for your app to request the WRITE_EXTERNAL_STORAGE permission to write to its own application-specific directories on external storage, which are provided by getExternalFilesDir(). However, the permission is required for API level 18 and lower. Example:
  File extDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);
• If the permission is a runtime permission or special permission, and if your app is installed on a device that runs Android 6.0 (API level 23) or higher, you must request the runtime permission or special permission yourself.
• On devices that run Android 4.4 (API level 19) and higher, your app can interact with a documents provider, including external storage volumes and cloud-based storage, using the Storage Access Framework. This framework allows users to interact with a system picker to choose a documents provider and select specific documents and other files for your app to create, open, or modify.
• To support media file access on devices that run Android 9 (API level 28) or lower, declare the READ_EXTERNAL_STORAGE permission and set the maxSdkVersion to 28. See reference 1.
• If your app targets Android 10 (API level 29) or lower, you can temporarily opt out of scoped storage in your production app. If you target Android 10, however, you need to set the value of requestLegacyExternalStorage to true in your app's manifest file.
