通过TestFairy部署Android时的异常

Question

我正在开发一个应用程序，一切都很好。但是，一旦我部署到使用TestFairy的测试人员，应用程序就会在某个时候抛出一个巨大的异常，我完全不明白。

例外情况如下：

JNI DETECTED ERROR IN APPLICATION: obj == null

这个

AsyncTask #1“prio=10 tid=35睡眠

是唯一引用我的代码的：

  at my.app.main.StoryViewActivity$PictureProgress.doInBackground(StoryViewActivity.java:332)
  at my.app.main.StoryViewActivity$PictureProgress.doInBackground(StoryViewActivity.java:310)

它指出了这段代码(简化)：

private class PictureProgress extends AsyncTask<Void, Integer, Void> {
    @Override
    protected Void doInBackground(Void... params) {
        while (!isCancelled() && progress <= C.STORY_PICTURE_DISPLAY_TIME) {
            work...
            try {
                    Thread.sleep(5); /* it points to this line */
                } catch (InterruptedException ignored) {
            }
        }
        return null;

}

在所引用的行号处是代码：

Thread.sleep(5)；/*为什么会失败？

现在，如果我通过Android在构建和发布版本中部署该应用程序，那么这个程序运行得非常好。但是我把它上传到了TestFairy，每次都会突然崩溃！

同样，相同的Thread.sleep(5)代码在应用程序的另一个点工作！(与TestFairy)

我很困惑，希望有人能帮我！

提前感谢，为长时间的异常代码感到抱歉。所有线程的完整异常长度为1000行:)

我是TestFairy的吉尔。

我们只在Android5.0.1上看到了这次崩溃，这里也是这样吗？操作系统中似乎有一个错误，这是我们无法修复的。

但是，好消息是，我们最近推出了Android，如果您进入SDK.html并按照那里的说明运行，您应该在几分钟内启动并运行。
