OK. But how to cram it when generating an outgoing apk?

how are you building the apk? Is this the internal build? Ie setting apde to app vs preview or are you talking about something else.

Have you tried setting the permissions in the build settings, ie settings \>build\>permissions.

Also i have created some code a while back to access permissions in android so that you will get the user choice popup to allow or deny a specific permission.

```auto
public class Permission{
  
  PApplet parent;
  String p;

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

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

};

```

then in your sketch

```auto
Permission p;

```

in setup

```auto
p = new Permission(this,"WRITE_EXTERNAL_STORAGE");

```

change the string value in the constructor to your required permission and finally make sure the matching permission is checked in the apde sketch and build settings.

so for example if I wanted to use the camera I would change the above code to .

```auto
p = new Permission(sketch,"CAMERA");

```

</div>

then make sure to follow the steps I’m suggesting.  
The permissions need to be set in the sketch settings and build settings

three dots \> sketch properties \> sketch permissions  
three dots \> settings \> build \> change preview permissions

then the code I’ve posted above needs to be added in android to request permissions from the user. Also note if you have already built your file once without asking for permissions you will need to delete the build file and reinstall it as further builds will never trigger the request.

that should be it for permissions.

How do normal people get the finished apk in APDE processing? not all, how do I use the additional total commander program to extract the apk installed on the system?

finally a full guide to install libraries on apde

> **[Installing Contributed Libraries](https://github.com/Calsign/APDE/wiki/Installing-Contributed-Libraries)**
>
> Source code for APDE: Create and run Processing sketches on an Android device. - Calsign/APDE

- Installation Steps
- If the library is in a ZIP or other type of compressed file, then extract it.
- Copy the extracted folder to the libraries folder in the Sketchbook folder and rename it to the desired name of the library., e.g. “path/to/Sketchbook/libraries/Ketai/”.
- Ensure that the library JAR file is located in the “library” folder in the library’s folder with the same name as the enclosing folder, e.g. “Ketai/library/Ketai.jar”. Copy any additional JAR files to this folder.
- Optionally, ensure that the library’s examples are located in the “examples” folder in the library’s folder, e.g. “Ketai/examples/”.
- Optionally, ensure that the “library.properties” file is located at the root of the library’s folder, e.g. “Ketai/library.properties”.
- Create a new folder at the same level as the “library” folder with the name “library-dex”, e.g. “Ketai/library-dex/”.
- Open APDE and navigate to (action overflow) \> Tools \> Import Library \> Manage Libraries \> (action overflow) \> DX Dexer. Note: The library should already appear in the list, but it has not been fully installed yet.
- In the “Input File” text box, enter the path to the library JAR file, e.g. “path/to/Sketchbook/libraries/Ketai/library/Ketai.jar”. You may use the file select button to aid in locating this file.
- In the “Output File” text box, enter the same path as above, but change the “library” folder to “library-dex” and change the library JAR file to “libraryName-dex.jar”, e.g. “path/to/Sketchbook/libraries/Ketai/library-dex/Ketai-dex.jar”.
- Press the “Dex” button. Wait for the dexing process to complete.
- Repeat steps 7 through 10 for any additional library JAR files.
- When the dialog closes, the library has been fully installed. It will now be automatically added to any sketch with the import statements at the top.

I havent tested all of these yet but I have attempted the traditional way and couldnt get them to load.

There have been many problems reported with adding libraries to apde

- 1 create new sketch.
- 2 change the sketch name  
 ![Screenshot_20210512_100335_com.calsignlabs.apde](https://canada1.discourse-cdn.com/flex036/uploads/processingfoundation1/original/2X/6/60ae06ec87593f44b8e361394e1450335b70341c.jpeg)
- 3 change the sketch display name
- 4 change the sketch package name  
 ![Screenshot_20210512_100346_com.calsignlabs.apde](https://canada1.discourse-cdn.com/flex036/uploads/processingfoundation1/original/2X/1/1a6a9e60882534eb9334e4f9f0eb9bdba52623f1.jpeg)
- 5 make sure apde is not building to internal storage

 ![Screenshot_20210512_085502_com.calsignlabs.apde](https://canada1.discourse-cdn.com/flex036/uploads/processingfoundation1/original/2X/b/bfae2d02343c1d2df72dace28bcee7905cd788f8.jpeg)

and select

- 6 install the library manually using the following steps

in your `sketchBook` folder create a new `libraries` folder. Here add a new folder with the name of your library (they must match), in that folder create a new folder called library, and in that folder add your jar file.

This will now allow you to be install them using the apde add library process

just use the latest version. I’ve posted a full guide above to install libraries, and so has Jafal. I understand you may be struggling, but the solution is there.

With both of these posts you should be able to

A add permissions.  
B add libraries.

Please make sure to follow the instructions carefully, and report any problems.
