所以我在 progard-rules.pro 文件中添加了这些行:
-keep com.dropbox.** {*;}
-keep com.google.common.** {*;}
-keep com.square.picasso.** {*;}
但是，我得到这个错误:
Warning:Exception while processing task java.io.IOException: proguard.ParseException: Unexpected keyword 'com.dropbox.**' in line 18 of file '/home/AndroidProjects/Poolex/app/proguard-rules.pro'
Error:Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'.
> java.io.IOException: proguard.ParseException: Unexpected keyword 'com.dropbox.**' in line 18 of file '/home/AndroidProjects/Poolex/app/proguard-rules.pro'
我该如何解决？
最佳答案
如果需要，您可以忽略来自混淆器的所有错误并尝试应用程序是否正常运行。我用这个
-dontwarn **
忽略所有错误。如果它不起作用，请尝试:
-保持**
如果你想只用一个，使用类似-keep class com.dropbox.**
或-忽略 com.dropbox.**

我有一个Ruby程序，它使用rubyzip压缩XML文件的目录树。gem。我的问题是文件开始变得很重，我想提高压缩级别，因为压缩时间不是问题。我在rubyzipdocumentation中找不到一种为创建的ZIP文件指定压缩级别的方法。有人知道如何更改此设置吗？是否有另一个允许指定压缩级别的Ruby库？ 最佳答案 这是我通过查看rubyzip内部创建的代码。level=Zlib::BEST_COMPRESSIONZip::ZipOutputStream.open(zip_file)do|zip|Dir.glob("**/*")d
