Android apkリリースビルドがproguardで失敗する

Question

私のAPKは、デバッグ時に&のデバッグで正常にビルドされ、テストデバイスにインストールされますが、期待どおり動作しますが、プレイストアリリースのAPKに署名するとき、ProGuard Cordova XWalkプラグインについて不平を言う。

私はアプリの開発にはかなり新しいですと、私は設定/それを使用する方法を知ってまで、私は何とかProGuardのを無効にすることができますか？または、それらの番号が設定されている多くの場所のどこかで、より高いSDKバージョン番号で再構築する必要がありますか？

Answer 1

ProGuardのminifyEnabledフラグがtrueに設定されているため、問題が発生しました。フラグをfalseに設定すると、ビルドに署名してプレイストアにリリースすることができます。私はそれを使って問題をデバッグする方法を知ってから再度有効にします。

build.gradleは

buildTypes { debug { debuggable true jniDebuggable false renderscriptDebuggable true zipAlignEnabled true } release { debuggable false jniDebuggable false renderscriptDebuggable false renderscriptOptimLevel 3 minifyEnabled false pseudoLocalesEnabled false zipAlignEnabled true } }

Answer 2

アンドロイドスタジオでのデフォルトの設定は解除APKでProGuardのを実行することです。 あなたはその buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard-rules.pro' } } のようなビルドファイルでそれを変更することができます。また、
