当我的应用程序崩溃时，我会在代码中随机获得以下波纹输出（与我可以识别的任何动作无关）。有人可以帮助我解释一下此logcat输出的含义。
我已经截断了文本的大部分，以列出各种线程及其状态（等待，定时等待，阻塞等）以及该线程上方法调用的堆栈跟踪。

07-31 14:39:43.630 942-947/com.salesrabbit.android.sales.universal A/libc: Fatal signal 6 (SIGABRT), code -6 in tid 947 (Jit thread pool)
编辑1
我昨天将我的android studio从3.0.1更新到了3.1.3（以及gradle），问题一直持续到今天午餐后才恢复。我试图使缓存无效并重新设置android studio，但它没有任何影响。在测试设备上构建/安装应用程序后约2分钟，我仍然收到此崩溃消息。它发生在我们所有的测试设备上。

我刚刚发现，如果我关闭所有断点，崩溃将消失。如果我把断点放回原处，崩溃就会回来。这很烦人！
在下面的代码中，如果我在db.endTransaction()上设置了一个断点，则应用程序将崩溃。为什么？我该如何解决？
return Single.just(page)
.map {
val db: Database = daoSession.database
db.beginTransaction()
. . . .
db.setTransactionSuccessful()
db.endTransaction()
return@map page
}
.map {
geoCodeAsNeeded(page.addressToGeoCode)
return@map page
}
.map {
return someMethod()
}
.subscribeOn(Schedulers.io())
答案 0 :(得分：3)
正如堆栈跟踪中的这一行所说：
致命信号6（SIGABRT），在tid 8509（Jit线程池）中的代码-6
您的错误是 SIGABRT信号。
1）不要阻塞UI线程，因为操作系统会导致SIGABRT 杀死无响应的应用。
2）确保在“活动”内的OnDestroy中 清理自己。即删除所有监听器/事件 然后调用Base.OnDestory。
3）外部（即BluetoothLeService）服务回调到 您的应用包含监听器，现在为null / nil会导致挂起，因此 SIGABRT，请参阅＃2

如果找不到错误位置，则必须通过更改代码部分以进行注释以查看问题是否能够找到它。
