Android Question B4A reinstall and Ok and error

[AnandGupta]

Well , thanks to 'Booklets' of Klaus and 'Video Tutorial' of Erel, I was able to install B4A 8.30 smoothly.
I already had earlier installation, which I uninstalled including Java.

The first test code ran successful in wifi connected b4a bridge in real device (Redmi 4).

After I close B4A and worked on other projects, I started B4A on same project and it gave error "The system cannot find the file specified"

Searching the forum I understood that I have to re-install B4A. My query is : Do I have to uninstall all i.e. B4a, Java, Android (tools) and reinstall all (it took rather very long time in my Win10 64 bit) or only B4A re-install will do ?

Any other short-cut method ? As I understand that the problem is created by Win updates more likely.

I have attached the project here, in case, any mistake in code.

You can find the Setup-Instructions here. https://www.b4x.com/b4a.html
You also can watch this Video as it describes it clearly.

Start with a new Blank folder for the SDK like you see in the Video.

Thanks DonManfred for suggestion, but looks like I was not clear in my message.

Not only I studied Erel's video, I also studied Klaus's booklet, (see my original message). They guided me on new installation.
Not only I installed in new folder, I installed in new drive.

I was just wondering if I have to again re-install B4A, Java and all OR just B4A.

EDIT: I re-installed B4A over itself. No luck. Same error message. Looks like I will have to uninstall all and re-install all.

This is the code as per Erel' video guide. (The code is attached in first post)



Can you guide why I am getting the error ?
Connection is Ok.

Is again clean re-install all the only option ?

Where is the project saved?

 

[AnandGupta]

The project was saved in E: drive and B4A installed in C: drive.
Taking cue from your query, I made new folder in C: drive and saved new project from B4A in it.
Bridge connection was Ok. Still same error.

Do you see the APK file in the Objects folder? Might be related to an over-aggressive antivirus.

 

[AnandGupta]

Yes, it is there in both drive folders,



I have also attached the full project folder, in case that helps. See if any solution can be found from it, else do not worry.

If I have to re-uninstall and re-install all I will do it next weekend as I have urgent projects now. I also got 8.50 beta, so will install that version.

Your project works fine here with B4A version 8.30, so I don't know what happens !?

 

[AnandGupta]

Yes, it did worked first time, that's why I wrote 'Ok' in subject line.
But after that it always giving 'device' error.
I have planned to do clean install again with 8.5 now after next weekend.

And Klaus, thanks a lot for writing the Booklets. The latest one is the best with separate folders and sample codes. If I can not make apps after reading it then I sure am not bright It is so much helpful for beginners. Thanks again.

Anand

I just found https://www.b4x.com/android/forum/threads/installing-file-to-device-error.58533/#post-369373
So this might be the solution, as my error is similar.
Still I will prefer to install 8.5 and also remember to re-install Android SDK.

Now to get some free time.
Is any app out there which can increase hours in as day ?
Come on, we can touch a glass to see world, can't we increase time !!
