Build a mobile app on Android
+Build a mobile app
-To build an Android app you need to specify the `IL2CPP` scripting backend and the `ARM64` as the target architecture in the player settings.-These settings can be accessed from the `Edit > Project Settings` menu within the `Player > Other Settings` section.
+**iOS** +iOS can be built with the default player settings. +**Android** +On Android you need to specify the `IL2CPP` scripting backend and the `ARM64` as the target architecture in the player settings.
+These settings can be accessed from the `Edit > Project Settings` menu within the `Player > Other Settings` section.
-It is also a good idea to enable the `Download on Build` option in the LLM GameObject to download the model on launch in order to keep the app size small.
+Since mobile app sizes are typically small, you can download the LLM models the first time the app launches.
+This functionality can be enabled with the `Download on Build` option.
+In your project you can wait until the model download is complete with:
+``` c#
+await LLM.WaitUntilModelSetup();
+```
+You can also receive calls during the download with the download progress:
+``` c#
+await LLM.WaitUntilModelSetup(SetProgress);
+
+void SetProgress(float progress){
+ string progressPercent = ((int)(progress * 100)).ToString() + "%";
+ Debug.Log($"Download progress: {progressPercent}");
+}
+```
+This is useful to present a progress bar or something similar.
+The [MobileDemo](Samples~/MobileDemo) is an example application for Android / iOS.
