Android应用需要构建两次以避免崩溃

标签： android android-gradle

我面临一个我根本不懂的问题。我有一个Android应用程序，在输入设置时会崩溃（下面的崩溃日志），但只是第一次构建时。这个问题是在调查为什么F-Droid构建出现故障时发现的，而我自己的工作正常。

重现的步骤如下：

  1. rm -r ~/.gradle
  2. ./ gradlew assembleRelease＆amp;＆amp; adb install -r ...

    3. 这里的构建成功完成，但APK不起作用。

    1. ./ gradlew assembleRelease＆amp;＆amp; adb install -r ...

      2. 第二次构建也完成，只有这次崩溃不再存在。有谁知道为什么会出现这样的问题？

      可以使用位于here的项目重现该问题。只需输入设置即可触发崩溃。这是完整的堆栈跟踪：

正如@CommonsWare建议的那样，通过禁用ProGuard发布版本解决了该问题。这证实了它是问题的根源，现在工作将开始确定某个地方是否缺少-keep选项。

关于两个后续版本不会生成相同APK的原因，我担心我永远不会知道。
