"Conversion to Dalvik format failed: Unable to execute dex: Java heap space"
The wolf has sniffing on the internet and found good solution for it.
The reason: Eclipse didn't allocate memory enough for running in this case.
The default memory setting on Eclipse (Indiago) was "-Xms40m -Xmx384m"
- Change these value to another bigger (like "-Xms256m -Xmx1024m") in the "eclipse.ini" file at the root of Eclipse's folder.
- Restart the Eclipse, you should terminate the "adb.exe" process in Tasks Manager. But, it doesn't matter.
- (HAVE TO) Clean up project and Build it again.
Then, it continue enjoying the bone.
