Android Question Installation problem

duneplodder · Dec 20, 2015

I've used B4A, on & off for several years. Yesterday I came to use it & it wouldn't install to my phone via b4A-Bridge. After much reading of the forums without success I decided to uninstall the SDK, Java jdk & B4a.

I followed the newer installation instructions page (https://www.b4x.com/b4a.html) but still have problems. I solved the "could not find dx.jar" error by creating a platform-tools\lib subfolder as opposed to the existing platform-tools\lib64 folder but get the error as displayed in the attachment.

I'm using Windows 10 & the jdk-8u65-windows-x64.exe java installation. I'm using B4A-Bridge to a real device & it is connecting OK. I'm using B4A v 5.50. This time I installed the SDK in D:\Android\ could it be a problem that it is on the D: drive?
Really not sure what I need to look for. I've never had any problems like this before.

Did you updated your systems Environment vars (JAVAHOME or something like that) to the new java location?

duneplodder · Dec 20, 2015

No. I don't remember doing anything like that before. What is the best way to do that in Windows 10? In msconfig or something like that?

Sorry, I got confused. I installed the SDK Not Java in d:\Android. Perhaps I should leave this a while as I'm going round in circles!

I've edited the original post & attached the error message I am getting.

It seems like there are multiple copies of ADB running. Try to restart the PC.

duneplodder · Dec 20, 2015

I've just seen your message & tried rebooting but it is still the same message. Task manager only shows one copy of adb.exe running.
Although it had been 3 or 4 weeks since I last ran B4A I can't think what might have changed.
Could the big Windows 10 upgrade a couple of weeks ago have caused a problem?

Try to install a new Android SDK in a different folder.

duneplodder · Dec 22, 2015

Thank you Erel. I uninstalled & reinstalled the SDK in C:\Android but I still get the same error.
I'll have to leave it until after the holiday, will try again next week.

I'm having another look at this.
I'm using Windows 10 which seems to have the .Net framework built in.
I looked in "Turn Windows features on & off" & ".Net Framework 4.6 Advanced Services" appears to be enabled.
Is there anything I should look for here?

I should emphasise that I'm using B4A Bridge on a real device (Moto G). It connects successfully as it always has, but when I try to run from the environment I get the error shown in my original post. I can manually copy the apk file across & install it successfully.

It is the same with my old HTC Flyer tablet.

According to Task Manager there is only one copy of adb.exe running.

Anything else I can try?

Erel · Dec 30, 2015

It is not related to .Net Framework or to B4A Bridge.

Open a command console (cmd) and go to Android SDK folder\platform-tools and run: adb devices

What is the output?

duneplodder · Dec 30, 2015

I attach a screen grab of the result.

None of the suggestions make any difference.
I presume that adb.exe is installed with Android SDK Tools? Perhaps I should try uninstalling & reinstall this?

Erel · Dec 30, 2015

Worth a try. adb is part of Android SDK.

JordiCP · Dec 30, 2015

I faced a similar problem, not with windows 10 but after an SDK upgrade

Look for all the versions/copies of adb in your system. And try what you did in post #11 with all of them.

If one is "good", you should copy that one in your SDK platform-tools path

duneplodder · Dec 30, 2015

JordiCP, Thanks - there was another version, but no luck.

duneplodder · Dec 30, 2015

Uninstalled & reinstalled the SDK. Same problem.

OK I've finally found the answer. I uninstalled Kaspersky Internet Security & B4A is now operational over the B4A-Bridge. For now I'm only using Windows Defender & the Windows Firewall. I can only think that some update messed things up? I had previously tried disabling Kaspersky and/or disabling the Kaspersky Firewall with no improvement.

I now have to decide whether to try reinstalling Kaspersky - I have 7 months license remaining!

Add b4a to the trusted apps in Kaspersky.
