Hi,  
I want to save and load a String in my programm.  
I could use:

```auto
saveStrings("filename.txt", new String[]{string});
loadStrings("filename.txt");

```

but the problem with these functions is (as far as I know) that they save the file at:

```auto
/data/user/0/com.yourCompany.yourAppName/files/filename.txt

```

The user cant open this Path. But in my case the User have to be able to open this path.  
For example a good save location would be:

```auto
/storage/emulated/0/MYAPP/filename.txt
//or
/storage/emulated/0/Android/data/com.yourCompany.yourAppName/files/filename.txt

```

So I want to create a custom saveStings function.  
Here is my attempt but its not working. can someone tell my why?  
Thanks in advance 🙂

```auto
import android.os.Environment;
import android.content.Context;
import java.io.FileOutputStream;

final String APP_FOLDER = "MYAPP";

void setup(){
  fullScreen();
  requestPermission("android.permission.WRITE_EXTERNAL_STORAGE");
  requestPermission("android.permission.READ_EXTERNAL_STORAGE");
  saveString("test", "text.txt");
}

void saveString(String text, String fileName) {
  try {
    File f = new File(Environment.getExternalStorageDirectory(), APP_FOLDER);
    if (!f.exists()) {
      println("create dirs");
      f.mkdirs();
    }
    println("Path: " + f.getAbsolutePath());
    File file = new File(f, fileName);
    println("File exists: " + file.exists());
    FileOutputStream fos = new FileOutputStream(fileName, true); // save
    fos.write(text.getBytes());
    fos.close();
  }
  catch(Exception e) {
    e.printStackTrace();
  }
}

```

If the cause  
‘android not saving Permission denied’  
If you say  
`android:requestLegacyExternalStorage="true"'`  
Please add

@GWAK thanks for replying,  
Where should I add this? android:requestLegacyExternalStorage=“true”’

This is the output:  
My println output

```auto
create dirs
Path: /storage/emulated/0/MYAPP

```

@Flolo

1. file : AndroidManifest.xml

2. copy

> android:label=“” android:requestLegacyExternalStorage=“true”

If it’s a permission issue  
just add that

Hi  
I get the same error as before…  
my AndroidManifest.xml:

```auto
