android studio中的proguard问题

我在android studio中开发了一个应用程序。它在调试版本中运行良好，但当我尝试使用proguard创建发布版本时，会出现数百条警告，我无法使用-keep选项消除它们

我的身材，格雷德尔是

例如，我不知道为什么添加-keep类jp.wasabeef.*{*；}不会消除关于jp.wasabeef的警告

有人能帮我吗？

您需要从混淆中排除这些外部添加的库代码。因此，您需要找到兼容的-dontwarn

对于joda添加：*-dontwarn org.joda.convert****

如果您使用的是任何pojo，则还需要使用以下方法排除它们：

-keepclassmembers为您的包分类。{；}**

您需要使用proguard规则处理导入的每个库（在app.gradle中）

proguard rules.pro

要使警告静音，可以使用

-dontwarn

。尝试使用此-keep class org.brickred.*{；}-dontwarn org.brickred.*@Lucho：我不想让警告静音，因为那样我的应用程序就不能正常工作了。我不想让它混淆。不管怎样，谢谢。@Shanrais:我不知道为什么，但放上“-keep class org.brickred.*{*；}-dontwarn org.brickred.*.”似乎没什么用。我以前试过。我不知道为什么。无论如何也谢谢你。请分享你的proguard-rules.pro；请在下面的“Chintan”中检查我的答案。dontwarn不排除，但避免就某个问题向您发出警告。我已经把所有我需要的dontwarn都放进去了，现在这个应用程序已经创建好了，但它不起作用。我需要排除库，但我不知道-keep选项似乎不起作用。请尝试为所需的类使用-keep。同样，如果您使用的是POJO，那么您不能让它们混淆。下面是一些更多的数据-keepattributes Signature#用于使用GSON@Expose annotation-keepattributes annotation#GSON特定类-keep class sun.misc.safe{；}#将通过GSON-keep class com.google.GSON.examples.android.model序列化/反序列化的应用程序类。*{；}为了修复protobuf错误，请尝试：-keep class com.google.protobuf.*{*}谢谢@Shanrais。你的答案很清楚，对我很有帮助。我认为对所有支持库使用**{*；}不是一个好主意。那为什么还要使用proguard呢？
