Emulator - Loading App

I'm still learning how to use the dev tools. Using MotoDev which is Eclipse, I wrote a basic "hello world" app. When I run the program, the emulator starts up. It took a few restarts of the emulator and Eclipse until my Hello World icon appear in the emulator. I noticed at one point that a status message said it was sending over the .apl file, which is when my app finally appeared in the emulator. I made changes to my code (Hello to Goodbye) and now..I can't figure out how to "send" to changed app to the emulator. The original app is n开发者_运维百科ot being replaced with the changes. What do I need to be doing to reload the changed application on to the Android emulator? Thanks

I havn't used MotoDev but I assume its pretty similar to the Google Dev plugin. In Eclipse go to:

Window > Android SDK and AVD manager

Under "Virtual Devices" select the AVD you have created and hit start.

Next go to Run > Run

When asked "Select a way to run ###" select Android Application

If you check your console you should get a message indicating the app is being installed, give it 30 seconds max and your app should be installed.
