Android Question New app gives "App not installed" error

[Arun]

Hi!

Fyi, I am testing on a OnePlus One Model A0001 with OS Cyanogen 12.0.YNG1TAS213

In the TRIAL version:
I downloaded and checked out the treeview example, the TwoDScroll demo and the ScrollView2D, all of which were installed and worked successfully on my device.

I then created an app to download files using httputils2 and string functions libraries which also worked beautifully on the same device. To neaten the app, I tried to insert a ProgressBar. This never worked, so i posted a question on the forum (see https://www.b4x.com/android/forum/t...ar-display-with-httputils2.56445/#post-355235)

Not getting a response after posting the code, I attempted some modifications. When I tried running the app, i was informed that the Trial version does NOT support these libraries. (https://www.b4x.com/android/forum/threads/string-functions.10365/page-10#post-355270)

I then purchased the Enterprise version on Saturday.

Now when I run ANY app, it remote compiles to the phone, but when I click on Install, it says "App not installed".

I created a new app, this gives me the same error.

I am at a loss as to how to proceed, what to check and where to check.

Please let me know if you need further details.

Thanks!

Are you using B4A-Bridge or USB debug mode? Have you tried to uninstall the app before you run it?

 

[KMatle]

Please uninstall all previous versions. Did you check, that the package-names must be different between apps?

I then created an app to download files using httputils2

Did you changed the packagename (most used curlpit) in your new app. It is named B$A Example by default...

I checked all the suggestions above and re-tried. No luck.

@Erel, I am using B4A Bridge in Wifi mode.

@KMatle, There aren't any previous versions of the App. This is a new app. I changed the Application Label on Line 2 of the project. Is there any other place where the app name needs to be set.

@DonManfred: I changed the Application Label on Line 2 of the project. Is there any other place where the app name needs to be set.

Thanks to all of you for the prompt replies!

 

[Erel]

Try to change the package name (Ctrl + B).

CTRL-B

Try to change the package name (Ctrl + B).

Thanks! New App got installed!

Now I will check my other apps.

Just a question - Why doesn't B4A Example show up in the Apps list? That would probably have given me a clue.

I had earlier uninstalled all the apps installed with the Trial Version, but B4A Example is not shown.

Does it mean an app with the name B4A Example is still existing on the device?

CTRL-B

Thanks! The app got installed!

a new project will become a packagename b4a.example and the label will get B4A Example
You need to change both for every new app
