2 原因分析
从崩溃栈中可以清晰看到原因，轻松得到如下结论：
2.1 非UI线程操作UI是Android不允许的
有人总结了Android平台下UI线程理解经验：
Single Thread Model 1. 一个组件的创建并不会新建一个线程，他们的创建都在UI线程中进行，包括他们的回调方法，如onKeyDown()。 2. 当在UI线程中进行某些耗时的操作时，将会阻塞UI线程，一般阻塞超过5秒就会显示一个ANR对话框。 3. UI线程是非线程安全的，所以，不能在工作线程中操作UI元素。 两个原则 1. Do not block the UI thread （不要阻塞UI线程） 2. Do not access the Android UI toolkit from outside the UI thread （不要在工作线程中操作UI元素） 在工作线程更新UI方法 1. Activity.runOnUiThread(Runnable) 2. Handler sendMessage(Message) post(Runnable) 3. AsyncTask execute() doInBackground() onPostExecute()
2.2 引发了JNI层崩溃
关于这一点，特别增加了日志可以确认，崩溃是因为NewLocalRef的时候发现有pending exception
3 推理过程
（1）为何第一次Java exception没有直接崩溃退出？
（2）如果说setText导致崩溃，那么为何设置“路径 1234567890”会崩溃，而设置“终点”二字却总也没崩溃？
这里先来分析第一点，直接给出下面答案：
3.1 JNI层处理Exception并不会立即崩溃
请参考这篇文章：《JNI官方规范中文版——如何在JNI中抛出Java异常》
![[Android] 分析一个CalledFromWrongThreadException崩溃](https://image.shishitao.com:8440/aHR0cHM6Ly93d3cuam13d3cubmV0L3VwbG9hZHMvYWxsaW1nLzIwMjAvMy9iRXpBejIucG5n.png?w=700 "[Android] 分析一个CalledFromWrongThreadException崩溃")
在我们的JNI层中，并没有调用
3.2 Android层Exception触发机制
先参考下这两篇背景知识：《Android View重绘与更新》《Android不能在子线程更新UI的讨论和分析》
从崩溃栈信息其实也能看出来，崩溃栈的关键信息有：

这里面有一个requestLayout，可以查到该函数用于Android控件的布局刷新，里面调用到ViewRootImpl.checkThread就会检查线程ID并抛异常。
那如果没有触发requestLayout调用是不是就不会做这个ThreadID检查和抛异常了呢？是的！

3.3 解答疑问
（1）首次回调时，因JNI层缺少ExceptionCheck() 和相应的处理逻辑，导致Java exception并不会立即崩溃而是逻辑继续。。。当（二次回调）发生NewLocalRef等操作发生时才检测到有pending exception引发崩溃
（2）非UI线程操作UI基本上都会崩溃，通过try...catch可以轻松获取信息。前提是需要触发checkThread调用。
（3）Android在setText操作需要重新刷新Layout时才会有CheckThread，进而引发崩溃。Text太短了不会触发requestLayout，哈哈
