使用Proguard后，Android Apk无法正常工作

Question

I'm new to proguard, and I got an issue that I don't know how to fix. I was able to create a signed apk of my app using proguard and to install it on my device, but when I try to launch the app I get:

java.lang.RuntimeException: Unable to instantiate application test.myapp.first.com.CustomApplication: java.lang.ClassNotFoundException: Didn't find class "test.myapp.first.com.CustomApplication" on path: DexPathList[[zip file "/data/app/test.myapp.first.com-2/base.apk"],nativeLibraryDirectories=[/data/app/test.myapp.first.com-2/lib/arm, /data/app/test.myapp.first.com-2/base.apk!/lib/armeabi-v7a, /vendor/lib, /system/lib]]

I tried to use -keep class in order to exclude the class and also Activity/Application subclasses from the obfuscation, and yes, in the android manifest the path to the application class is the full package path. I've decompiled the signed apk and actually the java class is placed in the correct path.

Any idea on how I can fix it?

Thanks

尝试使用sdk中的proguard配置，它位于tools/proguard/ ，例如proguard-android-optimize.txt 。
