Toris · Accepted Answer

この行をproguard-rules.proに追加します

_-keepattributes EnclosingMethod _

このエラーは、InnerClassesを持つほとんどすべてのクラスで発生する可能性があります。（support.v4など）私にとって。

私はAndroid studio 2.2でテストしました
（log4jはテストされていません。support.v4などがテストされています。）

build.gradle

_compileSdkVersion 24 buildToolsVersion "24.0.2" ... minifyEnabled true proguardFiles getDefaultProguardFile('proguard-Android.txt'), 'proguard-rules.pro' ... dependencies { ... compile 'com.Android.support:support-v4:24.2.1' } _

getDefaultProguardFile('proguard-Android-optimize.txt')も機能します。

activesince93 · Answer

私もこの同じエラーに直面していました。エラーカウントが1Kを超えていたので、私は夢中になりました。そして、proguardを有効にしたリリースビルドでこれらのエラーが発生していました。

掘り下げた後、-keepattributes EnclosingMethodあなたのproguard-rules.pro fileこれらのエラーはすべてなくなります。

Dina Mansour · Answer

これは私のために働いた、新しいAndroidスタジオプロジェクトのコピーを開始し、エラーがあった古いプロジェクトでgradle-wrapper.propertiesとbuild.gradle（プロジェクト： "プロジェクト名"）を貼り付けます-であなたのgradleをアップグレードするために

また、これをproguard-rules.proに追加します

-keepattributes EnclosingMethod

Build.gradle（Module：app）を次のように更新します

buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-Android.txt'), 'proguard-rules.pro' } } dexOptions { preDexLibraries = false }

Pankaj Lilan · Answer

プロジェクトのproguard-rules.proにこのコードスニペットを記述します。

-keepattributes EnclosingMethod

上記のスニペットをproguard-rules.proファイルに書き込むことにより、プロガードルールは実際にクラスの難読化方法を変更します。
