## Dev Notes - Checking App Size

It is worth occasionally checking that unused code is trimmed from the Android and iOS app packagings by the Mono linker.
There is [one known issue with this](https://github.com/fsprojects/Elmish.XamarinForms/issues/94).

App size on Android is checked by

1. build + deploying `Samples\CounterApp` (to device or emulator)
2. renaming and unziping `Samples\CounterApp\Droid\bin\Release\com.companyname.CounterApp.apk`
3. checking sizes and contents of

       Samples\CounterApp\Droid\bin\Release\com.donsyme.AllControls\assemblies\FSharp.Core.dll
       Samples\CounterApp\Droid\bin\Release\com.donsyme.AllControls\assemblies\Elmish.XamarinForms.dll

   e.g. see [this comment](https://github.com/fsprojects/Elmish.XamarinForms/issues/94#issuecomment-402157490)

Smallest app size is produced by

* "Generate one package per ABI"
* "Enable ProGuard"
* "Linking: Sdk and User assemblies"
* Disable debug instrumentation

Also check the app actually runs with these settings.
