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.

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

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.
