Permissions on an Android device

markcosmic · August 27, 2023, 8:18pm

Hi all,
I’m trying to understand which permissions I need to read/write a .txt or .csv file. As well as, the permissions needed to load and play a music file. Either on internal and external storage. Any advice/thoughts will be appreciated.
Thanks,
Mark

Hi

READ_EXTERNAL_STORAGE
WRITE_EXTERNAL_STORAGE

To give permission to the APP

In the Processing’s IDE Android mode Menu/Android/Sketch permissions

On the APDE you can do that by choosing: Three dots / Sketch Properties / Sketch Permissions.

Hi

Look at this examples

github.com

EmmanuelPil/Android-java-code-utilities-widgets-for-Processing-for-Android/blob/master/saveStrings().txt

// Be sure to give permission WRITE_EXTERNAL_STORAGE

import android.os.Environment;
import android.Manifest; 
import android.content.pm.PackageManager; 
import android.os.Build; 
import android.os.Build.VERSION_CODES; 
import processing.core.PConstants;
import android.app.Activity; 

Activity activity; 
boolean permissions_granted;
boolean file_saved;

// Folowing file name is the folder you save your text file in.
// If it does not exist it will be created automatically
String stringFolder = "MyStrings";

// Folowing string is the name of your text file
// Be sure to include extension.

Have a look at this thread too

The whole way external memory accessed started changing with Android 11 … You can’t just ask for permissions now … you have to use the Storage Access Framework.
