Android-Proguard和Google Play服務的應用導出錯誤

Question

我已將最新的Google Play服務添加到該項目中，現在proguard向我發出了許多警告：

[2014-07-31 17:21:50 - MyApp] Proguard returned with error code 1. See console

我嘗試添加

-dontwarn com.google.android.gms.*
-keep class android.support.v4.** { *; }

到proguard配置文件，但沒有運氣。 我在我的應用中定位的是Android 17（4.2.2），而最低SDK版本是8（我認為是2.2）。

解決該錯誤的任何幫助將不勝感激。

Answer 1

確保已使用Android 4.4.2設置項目，並且具有“ include android- support-v13.jar”。 我有同樣的問題，但現在已解決。

Answer 2

您是否添加了：

-keep class * extends java.util.ListResourceBundle {
    protected Object[][] getContents();
}

-keep public class com.google.android.gms.common.internal.safeparcel.SafeParcelable {
    public static final *** NULL;
}

-keepnames @com.google.android.gms.common.annotation.KeepName class *
-keepclassmembernames class * {
    @com.google.android.gms.common.annotation.KeepName *;
}

-keepnames class * implements android.os.Parcelable {
    public static final ** CREATOR;
}

在您的Proguard中？ http://developer.android.com/google/play-services/setup.html

Answer 3

似乎Google Play服務jar正在引用android-support-v13.jar中的某些類。 因此，在proguard-project.txt中添加以下行將解決該問題：

-libraryjars <ANDROID_SDK_PATH>/extras/android/support/v13/android-support-v13.jar

您需要使用Android SDK管理器下載此jar。
