SelectFile library generates a “FATAL EXCEPTION: main” error

Processing for Android

not sure how the lib works honestly, and I don’t feel like digging around in it to understand why, as I currently have a working solution. Is it the best probably not, does it allow me to pick a file or a folder yes. Image text etc, no problem. Of course this is just my personal taste.


import select.files.*;

SelectLibrary files;

void setup() {
  size(displayWidth, displayHeight);
  Permission p = new Permission(this, "WRITE_EXTERNAL_STORAGE");
  p = new Permission(this, "READ_EXTERNAL_STORAGE");
  files = new SelectLibrary(this);

  //files.selectFolder("Select a folder to process:", "fileSelected");
  //files.selectOutput("Save the file please:", "fileSelected");
};

void mousePressed() {
  files.selectFolder("Select a folder to process:", "fileSelected");
  //selectInput("Select a file to process:", "fileSelected");
  files.selectOutput("Save the file please:", "fileSelected");
};

void handleRequest(boolean granted) {
  if (granted) {
    println("1");
    files.selectInput("Select a file to process:", "fileSelected");
  } else {
    println("Does not have permission to read external storage.");
  }
};

void fileSelected(File selection) {
  if (selection == null) {
    println("Nothing was selected.");
  } else {
    println("User selected " + selection.getAbsolutePath());
  }
};

this is the permission class remember you also need to set permission in processing’s ide.

public class Permission{
  
  PApplet parent;
  String p;

  public Permission(PApplet pParent,String permissionName) {
    parent = pParent;
    p = permissionName;
    parent.requestPermission("android.permission."+permissionName, "onPermissionResult", this);
  };

  public void onPermissionResult(boolean granted) {
    if (!granted) {
      PApplet.println("User did not grant", p ,"permission.", p ,"is disabled.");
    }
  };

};

However the code above doesnt work even with permissions.
