ClassNotFound Proguardを使用した場合のGoogleApiAvailability

Question

私はGoogleのビジョンAPIを使用しているAndroidのaarを作成しています。 Playサービスが利用可能かどうかを確認するには、GoogleApiAvailability.getInstance().isGooglePlayServicesAvailable(context)を使用してチェックを追加しました。難読化されたときに

は難読化からこれを除くために私は私はこのエラーを取得しています

-keep class com.google.android.gms.vision.**{*;} 
-keep class com.google.android.gms.common.**{*;}

更新： 私はこのAARプロジェクトでplayservicesの依存関係を使用していますまた、私のコードは完全に動作しています。 プロジェクトにplayservices依存関係を追加することを避け、単にaarからそれを使用する方法はありますか？

Answer 1

ディレクティブ

-keep class com.google.android.gms.vision.** { *; } 

は、ProGuardのがcom.google.android.gms.vision.Detector$Processorようcom.google.android.gms.visionではなく、インタフェース内のすべてのクラスを維持します。

インターフェイスを維持するために第2のルールを追加：

-keep interface com.google.android.gms.vision.** { *; } 
-keep interface com.google.android.gms.common.** { *; } 

問題を修正すべきです。
