Aktivieren von PROGUARD - Xamarin.Android

Question

Im Freigabe-Modus, wenn ich nur Multi-Dex aktivieren, ist meine App-Größe 33,30 MB, die ziemlich groß ist. Nach einer Reihe von Recherchen wurde mir klar, dass PROGUARD die Größe der apk verkleinert. Aktivieren Progress in meiner Lösung, bekomme ich diesen Fehler. Was könnte ich in meiner Lösung für PROGUARD fehlen, um zu arbeiten (verkleinern Sie meine App-Größe)?

Answer 1

Proguard sagt Ihnen, dass Sie Ihre Warnungen beheben müssen, bevor sie es erlaubt zu bauen.

java.io.IOException: Please correct the above warnings first. 
     at proguard.Initializer.execute(Unknown Source) 
     at proguard.ProGuard.initialize(Unknown Source) 
     at proguard.ProGuard.execute(Unknown Source) 
     at proguard.ProGuard.main(Unknown Source) 

können Sie entweder gehen one-by-one all diese Fehler zu beheben (By -keep verwenden), oder Sie können die Warnungen ignorieren. Es gibt zwei Möglichkeiten, um dies zu:

1. Mit -ignorewarnings

Gibt Warnungen über unaufgelöste Referenzen und andere wichtige Probleme zu drucken, aber die Verarbeitung in jedem Fall fortsetzen. Das Ignorieren von Warnungen kann gefährlich sein. Wenn zum Beispiel die nicht aufgelösten Klassen oder Klassenmitglieder tatsächlich zur Verarbeitung benötigt werden, wird der verarbeitete Code nicht richtig funktionieren. Verwenden Sie diese Option nur, wenn Sie wissen, was Sie tun!

2. Mit -dontwarn [class_filter]

Gibt nicht über unaufgelöste Referenzen und andere wichtige Probleme überhaupt zu warnen. Der optionale Filter ist ein regulärer Ausdruck. ProGuard druckt keine Warnungen über Klassen mit übereinstimmenden Namen. Das Ignorieren von Warnungen kann gefährlich sein. Wenn zum Beispiel die nicht aufgelösten Klassen oder Klassenmitglieder tatsächlich zur Verarbeitung benötigt werden, wird der verarbeitete Code nicht richtig funktionieren. Verwenden Sie diese Option nur, wenn Sie wissen, was Sie tun!

Sie herausfinden können, wie eine benutzerdefinierte proguard Konfiguration über die Dokumentation erstellen Ich schrieb:

https://developer.xamarin.com/guides/android/deployment,_testing,_and_metrics/proguard/#Customizing_ProGuard

Warum Warnungen erhalten Sie diese können Sie fragen? Das liegt wahrscheinlich daran, dass der Linker diese Elemente entfernt, bevor Proguard ausgeführt wird. Siehe meine Notizen zu diesem Thema hier:
