“未知来源"在发布 apk [英] "Unknown Source" in release apk

问题描述

我的调试 APK 中的所有内容都运行良好.但是，当我导出 APK 并安装它时，一切正常，直到我调用引用的库.

Everything in my debug APK works just fine. However, when I export my APK and install it, everything works fine until I make a call to a referenced library.

E/AndroidRuntime(32571):    at com.znood.znoodapp.ShowResultsActivity.a (Unknown Source)

我正在使用 ProGuard.

I am using ProGuard.

我的库位于 libs 目录中并添加到构建路径中.

My libraries are in the libs directory and are added to build path.

非常感谢任何指针=)

推荐答案

问题出在 Google Gson 库上.Proguard 将类名转换为混淆的类名，从而导致 json 转换错误.

The problem was with the Google Gson library. Proguard converts class names into obfuscated ones rendering json conversion buggy.

为了解决这个问题，请确保您的 proguard-project.txt 中有以下内容

In order to solve this problem, make sure to have the following in your proguard-project.txt

# the classes that you use for Gson conversion
-keep class com.yourapp.objects.** { *; }

# without this line, I was having ClassCastException
-keepattributes Signature, *Annotation*

我希望这对某人有所帮助 =)
