Cause of the crash Android Part1

Let's make an application for Android !
I've been trying, and in that note was the cause hang.

Situation:
1. In Eclipse, from the base project, copy the project When creating an executable file, like it has been overwritten.
2. To change the name of the executable file, trial and error.

Execution:
The moment you start, a warning dialog appears, freeze.

Counterplan:
First, the situation had not run debug in Eclipse, and examine how thought.So, if you search on Google, get the information that can see a log ddms.
Hmm,, it appears a lot of logs, I do not know! I had given up, it seems to be only a means.So, I carefully check the log,,,.
Then, the "missing class!" Check the logs it.Saw looking at the project, the Name of the Service manifest.xml file, I at the x mark! Apparently, when a trial and error to change the executable file name, had failed to refactoring pattern.
