问题描述
我忙着写一个应用程序，我已经注意到，它有时会崩溃，而当它和我回到我的电脑，然后我只有堆栈跟踪。
I am busy writing an app and I have noticed that it sometimes crashes, and when it does and I get back to my computer then I only have the stack trace.

如果你调用android.os.Debug.dumpHprofData（字符串文件名），你可以捕捉，可以用或与jHat MAT被视为一个HPROF转储。你需要捕获的异常以某种方式（无论是try / catch语句或指定自己的全局默认的异常处理程序），如果你想写入/ SD卡您将需要WRITE_EXTERNAL_STORAGE许可。
If you call android.os.Debug.dumpHprofData(String fileName), you can capture an HPROF dump that can be viewed with jhat or MAT. You'll need to trap the exception somehow (either try/catch or specify your own global default exception handler), and if you want to write to /sdcard you'll need the WRITE_EXTERNAL_STORAGE permission.
