* We have implemented Play Asset Delivery to include the ZIM file within the Android App Bundle (AAB).
* To achieve this, we've created Gradle tasks to automatically download the ZIM file and place it inside the assets folder.
* In order to utilize this asset file, we've refactored our custom application code.
* We haven't removed the functionality of uploading the APK, as this approach remains static for now. Thus, we are retaining both codebases.
* In this update, we've replaced the `URLConnection` with the OkHttp library, and now headers are being correctly passed in the request. As a result, the Zim file is successfully downloading.
* To integrate OkHttp into our Gradle project, we've moved the OkHttp dependency to our `buildSrc` folder.
* if we run 2 servers at once (if in `app` server is already running then we can not run the server on the `custom` module since we can not run 2 servers on the same IP.) So for this, we have improved our code to show the proper error message so the user will know why the server is not running.
* We moved our server functionality to the core module to enable its use in both our app and custom modules. However, this change posed a challenge. We had a functionality that, when the user clicks on a notification, it takes them to the hosted book screen. By moving this functionality to the core module, we lost direct access to the navigation graph and `KiwixMainActivity` or `CustomMainActivity`.
* To address this issue, we introduced some abstract variables, such as navGraphId and mainActivity, which we set from both `KiwixMainActivity` and `CustomMainActivity`. This allows us to retrieve the navigation graph ID and the main activity.
* Additionally, we implemented a new function in `CoreApp` to set the currently running `CoreMainActivity`, which we use to obtain the navigation graph ID and main activity to perform the user click on notification.
* Moved wifi hotspot related files to core module to use hotspot functionality in both app and custom module.
* Moved permission in core manifest to access them in both modules.
* Removed some unnecessary files which is now no longer in use.
* Fixed, pdf are not opening with default pdf viewer.
* Fixed, sending email are failed with default email service.
* Fixed, opening support link, external urls with default browser.
* We have remove the authentication the url to make it normal url because we are adding authentication in headers so does not need to add in url.
* Enhanced getting secret function, if url is encoded then it will fail to get the secret from it so now we are properly decoding the url before extracting the secret key from it.
* To properly test these two functions we have added test cases for it.
* This test case is designed to verify that the functionality works correctly, especially addressing the issue where `LocalFileTransferFragment` would shut down when attempting to search nearby devices for connection.
* In Android 13, we previously used `intent.getParcelableArrayExtra` to retrieve the status of `P2P_DEVICE_CHANGED`. However, this method returned null because it's not actually an array. To resolve this issue, we have updated it to use `intent.getParcelableExtra`.
* For Android 12, we used to check the network state through `ConnectivityManager` every time the `WIFI_P2P_CONNECTION_CHANGED_ACTION` action was triggered. However, this approach wasn't reliable, as the action being triggered didn't guarantee a change in the network state. Instead, it sends an intent that we should now check for network changes. As a result, we have modified our code to utilize this intent within the `KiwixWifiP2pBroadcastReceiver`.
