java - Proguard 在尝试使用相机发送图片时导致应用程序崩溃

Question

我的应用程序已经过测试并且工作正常。但是当我尝试测试发布的 apk 时，它崩溃了。我包括了我的 proguard 文件和测试发布 apk 时得到的错误日志。基本上，当我通过 Intent 拍照然后尝试通过互联网将图片发送给收件人后，它就会崩溃。同样，我的应用程序运行良好:直到 proguard 加入其中。

注意:

发送图像的代码是 Runnable由 Thread 启动如 new Thread(runnable).start() ;非常基本的东西。同样，代码在 proguard 之外工作。

我的project.properties文件使用默认的 android 文件和我的。

明显的标志是这一行:

看起来一些 Apache 日志记录的类已被 Proguard 重命名，并且从 Proguard 配置文件中您可以看到

# -keep public class org.apache.commons.** { *; }

标记为注释(带有“#”前缀)，因此我会删除上面一行中的“#”，从而告诉 Proguard 不要重命名包 org.apache.commons 中的类，然后重试。
