eclipse: after signing with proguard, apk crashes


You can add this option to make the stacktraces a little more obvious but still obfuscated:

-keepattributes SourceFile,LineNumberTable,Signature


Alternatively you should de-obfuscate your stacktrace using the mapping.txt file that is generated when you create your proguarded build. This file is the "key" to changing your code back to normal. It is different every time you build a new apk so ensure you keep the correct file with the correct version.

Use retrace to de-obfuscate your stacktrace. (Get the crash stacktrace from your LogCat and save it to a file like obfuscated_stacktrace.txt.) Then run this command:

 retrace.bat -verbose mapping.txt
obfuscated_stacktrace.txt

I am facing this issue due to one external jar file. Where proguard is obfuscating it. As in my case airpush jar file is creating the problem. Just exclude it.

Retrofit @QueryMap with proguard
For retrofit you need to keep annotations. For that add this rule: -keepattributes *Annotation* Then you need your rule to keep Retrofit classes: -keep class retrofit.** { *; } And you probably need to keep your REST API and its API methods: -keepclasseswithmembers class * { @retrofit.http.* <methods>; }

Proguard and Netty 5 on Android
I have fixed this issue with some carefully* applied Proguard rules after reading through parts of the rather huge Netty sources: -keepattributes Signature,InnerClasses -keepclasseswithmembers class io.netty.** { *; } -keepnames class io.netty.** { *; } My original exception was caused by the type variables being removed from the bytecode, which Netty uses via reflection. Signature in -

Keep .so files from being trimmed when use Proguard in Android
Proguard shouldn't remove .so files, I guess your issue comes from something else. When you use "add native support" from eclipse, eclipse creates an empty ndk library project (a jni folder with empty sources and a sample Makefile). So when you build your app, eclipse empties libs/*/ folders, then build and install the newly created library here. If you don't use the NDK yourself (not compiling
