I am updating an Android project, and for some reason the run button in eclipse does nothing. I can get the app to run if I go Run>>Run Configurations... and then start it from that, but if I just click the play button or if I use the hotkey for run (CTRL + F11 ) then nothing happens. It seems to make no difference if an emulator is already going or not.
Anyone have suggestions? I like to code by making small changes and then running the app to see what happened and its very frustrating to have to go through 3 clicks just to get it to run every time.
Thanks
Using default settings in Eclipse, the Run button and hotkey CTRL + F11 will not work when the xml editor is in focus. It should work if you are working with the Java editor. To use the button or hotkey while editing xml, first click on the project in the package explorer.
You can adjust this by going in to Eclipse Preferences and choosing Run/Debug and make it launch your last used Run Configuration. Then only for the first time you launch you will be required to right click your project and choose Run As -> Android Application. After doing this pressing Ctrl+F11 or the Run icon will always start that Run Configuration.

Every time I run the application the run tab will open which is annoying, how can I prevent this?
you need to uncheck the Activate tool window

The emulator android is really running slowy, and I found Genymotion and runs really fast! And when I tried to use with Intellij, after I followed every step from this doc https://cloud.genymotion.com/page/doc/, I got stuck in this item:
In your application project, right click and chose "Run as Android
application" The "Android Devices Chooser" opens Click on the
Genymotion virtual device you started/created
I really can't find "Run as Android application" whenever I click on my folder project, where I'm missing?
Look at this image, I really don't know why.

In IntelliJ inside the Run/Debug Configuration dialog (available under Edit configurations...) you have to select radiobutton "Show chooser dialog" instead of Emulator.
Then you just press Run and you get the list of running devices.
If you select "Use same device for future launches" in the configuration dialog, you won't have to select the device again next time.
Check the toolbar of Intellij. There is a drop down menu (next to it are the "play" button and the "bug" button to start the debugger). You need to setup an Android configuration for your project first.

Although I have a configuration for my project, like you I can't see it in the menu your screenshot is showing. But I can use the mentioned run button to run my project without any problem.
Good luck.
On your screenshot you have a "Run" item on the options. Look at what appears when you let your mouse over it ;-)
This always worked before but since yesterday the little green arrow (green background, white right pointing triangle) does not work. Nothing happens, except maybe once in twenty tries. I have to push the small black down facing triangle right to it and launch the project from the popup menu.
I also have a keyboard shortcut bound to the same "Run" command. Also this shortcut has the same problem. It only rare works since yesterday. Most of the times there's nothing happening at all. No output in Console.
Try this:
Clean Project -> close all files
Restart Eclipse
Right click on project -> Run As -> Android Application
Try the run button again.
Let us know the outcome.
Not sure whether is this the case or not. When you working on your XML or Manifest and you launch your application it wont really work. It will launch your xml file instead and might create an extra file in your project. Try to launch your application in an activity(Java) page.
I have troubles compiling my code with eclipse. Each time I click the run button it opens a new AVM.
I am starting to get lost in here any hint or solution please?
The run button in eclipse is designed to launch your code, which has to be done either in the AVM or on hardware connected to your computer. If you are wanting to build the binary without executing you go to the project menu and select Build All. However, it is probably set by default to build automatically, which is also under the project menu. Effectively this means the code you are writing is being built "on the fly" and errors will appear dynamically as you write your code. Is this what you were asking?
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 as", then "Android Application". There has to be a better way...
Is there a way to change this (three mouse clicks):
"Right click on project" -> "run as" -> "Android Application"
To this (one hotkey press):
<My favorite hotkey>
So I can just press one button to launch my app?
Thanks!
Eclipse/Window > Preferences > Run/Debug > Launching
Select 'Always launch the previously launched application' in the 'Launch Operation' section.
Then just use your shortcut of choice. I think Ctrl + F11 is the default for this
In preferences, go to General -> keys and search for the Android Application command. You can set a new key combination from here.
On MacOSX, for me worked Cmd+Shift+F11, which came down on laptop keyboard to Cmd+fn+Shift+F11
I am not sure why the last answer is voted down, as I think it is the best answer. In the standard ADT Eclipse tool bar, there is the following button:
If you are editing a Java file, and press this button, your app will automatically be launched. Thus, this is one the one button press to launch your app.
As with the other shortcuts mentioned here, this does not work if you are editing an XML file (so ensure your editor is showing a Java file).
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!
If you want to run your app when a XML file is open in your eclipse you must set your run configuration
Eclipse -> run -> run configuration -> Android Application in left window -> your configuration -> android tab in right window -> launch -> select your main activity
For this you can use (ctrl+F11) , which shows all online devices which is used as emulator
Eclipse toolbar has green run button which has default meaning run last selected configuration. Just click there.
