Android Question Unable to run the KeyValue Store examples

[beelze69]

Hi,

I tried to execute Erel's KeyValue store example in the below posts

[B4X] KVS2 / KeyValueStore 2 - Simple & Powerful Local Datastore

Recommended to use the newer b4xlib: https://www.b4x.com/android/forum/threads/b4x-kvs2-keyvaluestore2-library.120234/

www.b4x.com

as well as the latest

[B4X] KVS - KeyValueStore library

A key / value persistent store. The data is serialized using B4XSerializator and is stored in an internal database. The database can be shared between B4A, B4i and B4J. Using KVS is similar to using a Map. You initialize it once and then you can put or get items with Put, Get or GetDefault...

www.b4x.com

Also I copied the referenced newer Keyvaluestore library in my extralibraries folder.

However, I am unable to install the APP on my mobile in both the cases..

I tried even in Debug Mode, hoping that some error message might get thrown but there was none..

What could be the problem ?

Please help.

Thanks..

Can you report that this only happen to your new device with new version of Android and/or new version of B4A?

 

[aeric]

Which sample project are you running? Can you point the link?
The latest library version 2.31 is an Internal library.

What happened when you install the app? Is there any message or log on your phone or b4a?

No Message.. nothing.. I even tried in debug mode so that on the logs some error message will be thrown ... but there was none...
The standard app installation dialog simply says 'cannot install app'...

Do you have a screen shot ? did you test it on emulator? I don't think it is useful to debug mode if it is not installed successfully

But for simple hello world app (B4XPages or Default) any issue?

I just solved my phone debug issue.
Run the sample project on Android 12. No issue installing in debug mode, it shows the smiley face and logs.

I also tested the project from post #5 and it runs OK in Debug and Release mode withe B4A 12.20 on my Samsung Galaxy S10 Android 12.
Try to change the Package Name in the menu Project / Build Configurations.

Sorry !
How do I run it on Android 12 ?
Do I have to make any change in the settings ?

It seems there is an old app on your phone. please delete the app then reinstall.

Thanks Klaus !

It worked !

When I changed the package name from b4a.example3 to b4a.keyvaluestore , it worked...

Can you guide me what has the package name got to do with this ?

Hi Aeric !

It worked when I changed the package name (as per Klaus suggestion)..

Thank you for your responses.. But please tell me what you meant when you said to run on Android 12...

But I have another issue.

I created a blank B4XPages app (the earlier example was an Activity based app) but in that I am unable to check the KeyValueStore or the KeyValueStore2 library reference.

What could be the issue ?

Thanks...

You'd better create a new thread and post issue's log or screen shot or the small project..

I was just guessing maybe something has changed in newer version of android. My development phone and emulator are running on old android and I just tested on newer version and having no issue.

The issue you were facing, unable to install is due to reuse package name. Maybe the conflict happened due to the new app you are installing is very different in term of libraries used and too much different in code or private sign keys are different so you are forbidden to overwrite the old app with same package name.

Everytime you try to run an example project from forum, it is good practice to change the package name first to avoid this happen again or uninstall the example apps after testing. My 2 cents.
