所以，我一直在尝试将多项目（eclipse项目）应用程序的开发迁移到Android Studio（v1.1）。
通过文件导入＆gt;导入项目非常简单，没有发生任何事故。
然而，当我尝试Make / Rebuild项目时，我遇到了许多惊喜。第一个与Proguard无关，与源文件编码有关（最初在Windows-1252中），但我很快找到了使用此Windows-1252 > Reload > UTF-8 > Convert答案的解决方案。
然后，＆＃34;错误：找不到符号类＆＃34;对于我的com.comp.mod.X类。然后我通过转到包含该类的模块（Android Studio模块，以前是Eclipse项目）并将其添加到 proguard.cfg 中来解决它：
-keep public class com.comp.mod.X
这给我留下了一个＆＃34;错误：无法找到符号变量＆＃34;对于在上述类中定义的const BB。我通过添加以下 proguard.cfg 来解决这个问题：
-keepclassmembers class com.comp.mod.X {
public static final boolean BB;
}
这让我只有一个＆＃34;错误：找不到符号方法getPreferenceX（）＆＃34;。我通过添加相同的 -keepclassmembers 那个方法来解决这个问题，所以上面现在看起来：
-keepclassmembers class com.comp.mod.X {
public static final boolean BB;
public static java.lang.String getPreferenceX();
}
我以为我已经完成了，但令我沮丧的是，当我尝试重建项目时，我从项目中的其他模块收到了许多其他错误，所有类型都为＆＃34;错误：找不到符号类/变量/方法＆＃34;并与某些 proguard.cfg 相关。
我可以继续屠杀每个模块的proguard.cfg文件但是在这一点上我开始怀疑我做了一些根本错误的事情，因为那些proguard.cfg文件在Eclipse下完美运行。所以，
我错过了什么？
注意：我不尝试＆＃34;生成签名APK＆＃34;。我所做的只是＆＃34;重建项目＆＃34;。
