Question

我在我的项目中使用v4兼容包，但是当我尝试导出已签名的应用程序时，我从Proguard收到以下消息。我整个晚上都用Google搜索，但我找不到解决这个问题的答案。

[2011-07-03 01:46:29 - worldscopeApp] Proguard returned with error code 1. See console

Answer 1

看起来android.support.v4中的一些clases与android中的某些类不完全兼容。如果您确定这不是问题，可以指定

-dontwarn android.support.v4.**

然后，ProGuard将忽略这些问题并继续处理代码。

请参阅ProGuard手册＆gt;疑难解答＆gt;警告：找不到引用的字段/方法

Answer 2

这就是我在proguard.cfg中使用的内容：

-dontwarn **CompatHoneycomb
-keep public class * extends android.support.v4.app.Fragment

更一般的是：

-dontwarn **CompatHoneycomb
-keep class android.support.v4.** { *; }

但是它会导致更大的APK大小，所以只有在第一个不起作用时才会使用。

Answer 3

您应该将android：targetSdkVersion设置为SDK＆gt; =蜂窝。

有关我使用此信息的信息

<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="13"/>

使用android.support.v4.app蜂窝兼容包导出签名的应用程序时出现Proguard错误
