I\'ve been programming Android in Eclipse for about a year now and I have always launched my app by right clicking on my project name in the project explorer, followed by \"run
1) Eclipse/Window > Preferences > Run/Debug > Launching
2) Select 'Always launch the previously launched application' in the 'Launch Operation' section.
3) Then just use your shortcut of choice. I think Ctrl + F11 is the default for this
Someone suggested the above and it worked for me!
