Eclipse and Android - Problem installing APK?

I ran into this issue multiple times and have solved it 99% of the time by running the Emulator and letting it get stable -- once it was stable I clicked 'Run' again -- SUCCESS! If you're still having issues, check what programs are currently running in your computer's background. When an install failed, I exited PowerISO which I had running, tried again, and it installed successfully!

Good luck! =).

I'm also new to android and I'm still running into into this problem (running SDK 3, Version: 10.0.0. V201102162101-104271). I've tried this procedure with mixed results: Eclipse isn't talking to the emulator FAQ.It's not clear to me whether or not it's OK to have multiple copies of an app on the (emulator?

) target. I wouldn't think so but, while I have seen this output in my /data/app directory (see below) it's possible that was a transient state. Root@android:/data/app # ls ls ApiDemos.

Apk CubeLiveWallpapers. Apk GestureBuilder. Apk SoftKeyboard.

Apk WidgetPreview. Apk com.example. Apk com.example.

Apk vmdl-206041726. Tmp I think that, by observing the logcat output, most of the times that I've seen that failure there was a failure to uninstall the older version of the app. But, being a newbee, I can't be sure.

I read that you can go into the /data/app directory (run 'adb shell' then 'cd /data/app') and delete the ...helloandroid-x. Apk file before attempting to install the new apk. I haven't tried that approach yet.

Finally you can uninstall using this approach: adb uninstall com.example. Android If this helps you'll be luck not to run into the problem I'm having now, which is: I can't get the app to start from eclipse so I can't debug/step through code.

This has happened to me in the past, it was solved by simply attempting the install again once the emulator was booted up properly. Give that a shot. If that doesn't work: Ensure the emulator you've created is equal to the targeted sdk you've set for the app.

Look for any null pointers in the app, maybe a typo? Ensure that the emulator supports all the features you require in the application (probably not the case with hello world) try a clean + re-build of the app, then try to install it once you've done that.

What do you mean by "attemping the install again once the emulator was booted". Should I start the emulator via the AVD manager, and once it boots keep it running and try to launch my program? – Tim Mar 8 at 3:18 Well you could do it like that.

I mean that once the emulator has booted up hit run in eclipse again. That has solved it for me 95% of the time. – providence Mar 8 at 4:20 @Tim, has any of this worked?

Let us know, perhaps we can help more. – providence Mar 8 at 18:17.

This seams to be a common problem since there are more then 100 posts out there (which I found on Googles first site) which cover this problem. It seams that this is just something that you can't really answer because it seams that there is an individual solution to this problem. See the previous questions: Android- World Android Failed to install Apk on device (null) Error Also, there seams to be another working solution out there (at least for some people).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
