我遇到了一个问题，我认为是由android工作室造成的。我正在开发android工作室的稳定版本。当它在调试时，一切都很好。但是，当我切换到发布变体或者生成一个签名APK的时候，这个应用程序就会在不同的场合崩溃。堆栈跟踪是：

代码语言：javascript

java.lang.NullPointerException: Attempt to invoke interface method 'boolean android.view.inputmethod.InputConnection.finishComposingText()' on a null object reference

故障排除步骤：

  1. 换了测试电话。
  2. 尝试D8编译器
  3. 在DEbug和版本变体之间来回切换

因此，最后一次尝试是在不同的android工作室(实际上是不同的PC)上运行完全相同的项目。这个应用程序开始了，我玩了一段时间，很好。没有撞车也没有可疑。甚至尝试过不同的手机，但撞车事件没有发生。

我的设置：

  1. Mac版本10.13.4
  2. Android 3.0.1版

另一个计算机设置：

  1. Windows 10
  2. Android 3.0.1版

任何帮助都将不胜感激。

更新：

经过尝试，禁用的保护发布版本现在是好的，但现在的问题是，相同的规则和依赖关系已经应用到这两台PC，但保护功能不同！

依赖关系：

更新2.我刚刚成功地将我的安卓工作室更新到3.1.1版本，并将gradle和插件更新到最新版本。

不幸的是，错误仍然存在，只有堆栈跟踪已经更改：
