android应用未安装，eclipse juno

Question

I'm using Eclipse IDE for Java EE Developers. I created my first android application project, and it's supposed to display the Hello World message, but I run it and get nothing(well, the emulator starts but then nothing), no console output view, no error.If I run it again the console appears(...WARNING: Data partition already in use. Changes will not persist!) and the emulator opens in new window but again nothing Please tell me what's wrong and how to install and run the app? after first run(pic1&2), after second run (pic3)

Answer 1

Reset/Restart the adb server . You should do that over the command line. Make sure that you are in your /android-sdk-root/platform-tools directory.

adb kill-server
adb start-server

Answer 2

运行应用程序时，您将在“ bin”文件夹下看到.apk文件。

Answer 3

wait! As far as i can make out, you're just launching the emulator. Isn't it? there's a green button at the top. (like a "play" button) just press it.

Or right click on the project you want to run, and click on "run as > android application" and watch the emulator play your app.

Answer 4

It sounds like the emulator is already running and you are launching a new instance of it... based on the log it has been launched earlier and perhaps it hasn't shut down properly.

-Restart adb as poitroae suggested in an earlier answer.

-If that doesn't help, restart Eclipse.

-If that doesn't help, restart your computer.

If you're still having issues after that, post back.

Answer 5

try to clean your project from project-> clean and also donot forget to wipe user data on android emulator... here is some good discussion about your problem...

Using Eclipse for androidSDK, when I go to run, I get WARNING: Data partition already in use. Changes will not persist!
