Question

I’m sure the problem has already been solved 100 times, but i cannot find a solution that works for me.

I have developed an application and testeed it (USB-Debugging) on a htc Sensation. Now i want to release. So I use the export WIzard of Eclipse to create the signed Apps .apk.

I deinstall the app on the htc-sensation and restart the phone.
Copy the apk to sdcard, install the app, (restart the phone just in case) and run the app. Works.

Then i grab my Samsung galaxy s3, check “unknown sources”, copy apk to scdard, install (restart phone just in case).
If i want to start the app i get the Toast “App is not installed”. It is listed as Installed and i can deinstall and reintall it (without an effekt on the error).

Also if i want to debug in my s3: (USB debugging is enabled, i can select it from the list in eclipse as debugging-target)

Console says:

Android Launch!
adb is running normally.
Performing com.myapp.main.MainActivity activity launch
Uploading myapp.apk onto device '4df1fee466246ffd'
Installing myapp.apk...
Success!

But the app neither starts running, nor can i start it manually (same Toast message “App is not isntalled”)

already tried:

of course multiple phone restarts and reinstalls
reexporting the apk

remove and reapply sd-card

install with adb install command

the s3 runns android 4.0.4, the htc 4.0.3, the app requires minimum 4.0.3.

What am i missing about this?

Remove you Internet Permission from the Application Tag . It Declare twice . So your application declaration looks like this now:

<application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name">
