Question

当我做这样的事情时：

try{
    row=inflater.inflate(R.layout.row2, parent, false);
}catch(Exception e){
    Log.e(TAG,"error",e);
}

我在LogCat中获得了预期的堆栈跟踪。但是，如果没有它，则错误未被捕获，但我仍然期望未经过滤的Log中存在痕迹。但为什么不存在呢？没有它，我在“Debug”选项卡中看到只有一个exeption状态（调用堆栈？）有些地方不能使用try..catch，例如在xml文件中。

现在我面临运行时异常。未经过滤的日志是这样的：

我没有看到任何错误，而调用堆栈显示：线程挂起（异常运行时异常））

但这似乎很可疑：

09-06 20：48：24.545：INFO / DEBUG（2574）：pid 11805中不存在tid 11811.忽略调试请求

当选择要启用Debug的设备时，我的手机的“Debug”字段为空，1.6模拟器显示“是”

Answer 1

如果此代码抛出异常并且代码中的任何地方都没有异常处理，那么您肯定会在logcat中看到它。

Answer 2

问题是调试器在打印堆栈跟踪之前暂停了异常。因此，您只需按几次调试面板中的继续按钮（看起来像我＆gt;），即可打印跟踪。当您在设备上看到强制关闭对话框时，跟踪必须在LogCat中。

默认情况下启用堆栈跟踪
