啓用Proguard拋出異常

-1

我在項目中添加了一些外部庫，它工作正常，但是當啓用proguard時，它每次都會拋出異常。我試圖從proguard中排除庫，但我的代碼不工作。啓用Proguard拋出異常

gradle這個：

dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    compile 'com.android.support:appcompat-v7:21.0.3' 
    compile 'com.google.code.gson:gson:2.3' 
    compile 'com.android.support:support-v4:21.0.3' 
}

proguard-rules.pro

-keep class android.support.v7.** { *; } 
-keep interface android.support.v7.** { *; } 
-keep enum android.support.v7.** { *; } 

-keep class android.support.v4.** { *; } 
-keep interface android.support.v4.** { *; } 
-keep enum android.support.v4.** { *; } 

-keep class com.google.** { *; } 
-keep interface com.google.** { *; } 
-keep enum com.google.** { *; }

錯誤

你在代碼中的任何地方使用反射嗎？也許使用ObjectAnimator？ – 2015-03-02 12:37:21

此外，請發佈您收到的錯誤。 – 2015-03-02 12:38:09

@GilMoshayof：我沒有使用反射 – 2015-03-02 12:40:18

我使用GSON李b並在proguard及其作品中嘗試了這一行。

-keepattributes Signature
