Tango应用程序突然中断JNI DETECTED ERROR IN APPLICATION

标签： java android java-native-interface tango

我正在使用Google Tango开发应用。有一段时间一切正常，但昨天在重构了一些变量并恢复了一些变化之后它突然爆发了。启动应用程序时，我收到以下错误日志：

我将原因缩小到这条线：

mTango.connectListener(framePairs, new Tango.OnTangoUpdateListener() {...});

但是由于错误没有提及我的代码的任何部分，我不知道在哪里可以看得更远。

我在研究问题后到目前为止的调查结果：

  • 监听器是否包含代码无关紧要。
  • 错误仅在相机拍照后发生。因此，只要设备位于桌面上以便相机被阻挡，那么应用程序在技术上运行良好。
  • 即使之前的应用程序曾经工作过，现在甚至早期的提交都已破坏。
  • Google的基本示例仍可正常使用。
  • 使用不同版本的Tango或Android不会改变任何内容。
  • 清理gradle或进行全新安装不会改变任何内容。
  • 我在Stackoverflow的另一个线程中发现原因可能在于库的代码，但是因为它之前没有看到它是如何工作的。

有没有人知道如何解决这个问题？

1 个答案:

答案 0 :(得分：0)

你有没有改变过Tango Core？我昨天在我的Phab2上更新了Tango Core遇到了这个问题。我猜你应该尝试最新发布的SDK“Eisa”来解决这个问题。
