Android - proguard 和 google play 服务的应用程序导出错误

Question

我已将最新的 Google Play 服务添加到项目中，现在 proguard 正在提供 我有很多警告：

我已经尝试添加

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

到 proguard 配置文件，但没有运气。我在我的应用程序中定位到 android 17 (4.2.2)，并且最低 SDK 版本是 8（我认为是 2.2）。

任何解决此错误的帮助将不胜感激。

Answer 1

确保您已使用 Android 4.4.2 设置您的项目并且您已“包含 android-support-v13.jar”。我有同样的问题，但现在已经解决了。

Answer 2

你添加了吗：

-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;
}

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

Answer 3

似乎 google play 服务 jar 引用了 android-support-v13.jar 中的一些类。 因此在 proguard-project.txt 中添加以下行将解决问题：

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

您需要使用 Android SDK 管理器下载此 jar。
