阅读更多关于 Android: how to debug app's start-up process

问题 I am investigating some issues which happen during my app's startup process, but DDMS won't start the debug mode until the process has started, is there a way I can capture the events earlier? 回答1: I know that this is a couple of years late, but for any future searches: Putting WaitForDebugger into your code is one way.

问题 I really thought that after about 200 or more tomcat installs on various platforms, I am ready for any kind of challenge but this one is tricky. I created a vanilla Ubunutu 14_04 image and installed Java 8 TGZ from oracle on that system. Furthermore I added a tomcat 8 to the game. Then I started the vanilla server install. Soon after hanging on deploying the default apps shipped with tomcat, I wondered whats happening there and did some threaddumps. This one was the lousy thread who prevented
