Eclipse (Android): When clicking 'Run'/'Debug' nothing happens

Question

I have just installed (extracted) properly the ADT bundle for eclipse + android SDK and also set a new AVD which is currently working on my background and looks fine.

my problem is: once i create any app and click the 'Run' or 'Debug' button, nothing happens. I don't see any 'launching : (nn%) ..' message at the bottom and the AVD is not effected at all - nothing happens! I have no idea what is the problem but a while ago i installed this exactly same way and had seen this issue before. could anyone please advice me what to do?

Answer 1

right click you project->run as -> run configuration, check whether launce default activity is selected, and in target tab check "always prompt to pick device"

Answer 2

If the button works fine for the first time and doesn't work later, try this.

Open Devices view using Window > Show View > Devices.

Then, in Devices, under your emulator, find your application package name. Select it and press the red "STOP" button.

After this, the application should run properly.

Answer 3

In the editor MainActivity.java file should be open/in focus.Then run your app. It should work fine. Problem occurs when some other xml file is in focus in the editor eg.styles.xml etc.
