    I used an app called "AppMgr III" to see what would happen if someone moved my app to external storage. It didn't run after moving it. I tried removing it and reinstalling it, but it will no longer install. I get the message "App not installed" when trying to install it from the Play Store or from B4A-Bridge. I've tried changing all of the project attributes (ApplicationLabel, VersionCode, VersionName) without success. How can I undo whatever has been done?

    Did you uninstall it using AppMgr III? It may be blocking the subsequent installs if not.

    To make it a different app as far as the OS is concerned, you need to change the package name, but that's a drastic last option.
    You could also try uninstalling AppMgr III.

    maybe a stupid question but, did you set "can instal to SD" to true?

    I removed my app using the normal Android based method. I did not use AppMgr III. I tried uninstalling AppMgr III with no change in behavior.

    "Can install to SD" is set to be true.

    Since this line of questioning isn't going too far, what can cause an "App not installed" message? What vestiges of the installation should I look for and where are they located?

    Hi Geoff, it doesn't appear that this question has arisen before on the forum, so it's not surprising that no one can give you a quick answer. As it's a general Android issue (not B4a specific) you'll probably find the answer quicker by Googleing the problem. In fact doing that, there are half a dozen things to try on the first page of results.

    As I can't recreate the problem I can't try them out and give you a definitive answer, so give it a go and let us know how you get on.

    Try to set: #CanInstallToExternalStorage: False

    I have tried everything that I could find through Google. Nothing solved it. Finally I did a factory reset and that solved the problem. I'm leaving on a 4 month trip to Panama/Colombia tomorrow where I'll have very limited Internet, so I figured that it would be less painful to re-install everything from here.

    Thanks for the suggestions. I'm keeping away from those types of apps in the future!
