Android Question B4A 10.70 Does not Compile

[ColorMan]

So I updated to the latest version of B4A this morning. And I cannot get B4A Example 4 the Guess My Number example to compile. When I load and run I get the following message

Signing package file (debug key). Error
Unsupported option: --v3-signing-enabled. See --help for supported options.

In the video tutorial the top line here reads: Signing package file (private key).
But there is no mention of setting keys for debug.

I am using the Bridge to a real device, Android Tablet. The Tablet is enabled for USB debugging. The last time I tried this program I was using Android 8 and now I am using a new device with Android 10. So I do not know if B4A 10.7 is the issue or if Android 10 is the issue.

As explained at the end of this thread, you need to install Android again.
I had the same problem, reinstalled Android according to the link in the thread mentioned above.

I saw these instructions but I have already installed the very latest version of Android Studio just last week. So why would I not have the very latest version of the SDK?
I copied the information from the links given. As I did, I checked on names (for appended version info), dated and sizes. As I indicated, while Erel's video guide showed him creating new folders, I already had those folders and the subfolders and files were the same names, sizes and dates, with one exception - one file in the support tools from the B4X site had a new version number. Now I am able to compile B4A projects.

B4A never uses the same SDK as Android Studio.

You need to download the two components: https://www.b4x.com/b4a.html and configure the IDE to use that SDK. Everything will work.

So, does this mean that I must choose between using B4A and Android Studio? It is not possible to run both on the same computer? In following your instructions to avoid this compilation error - I observed that at least 95% of the files copies had the same name, the same data and the same file size. The folder names that you suggest were already on my computer - put there by the installer for Android Studio. If that 5% of unique files were all that is uncommon between the two platforms, why did you not give them unique names, like a B4A prefix?

No. Just install the SDK for B4A in its own folder and point B4A at it. Android Studio can have its own installation.

 

[ColorMan]

Where is the pointer set? I do not see instructions for changing the folder names in the install directions given by Erel.

It's there, you must have missed it.

Tools -> Configure Paths -> Set "android.jar" path to the android.jar file in the folder where you installed the B4A SDK.
For example I have the SDK in C:\Android and my path is C:\Android\platforms\android-30\android.jar

 

[ColorMan]

OK - I see. I believe that the instructions were to set the folder to C:\Android for the SDK but that is the same name used by Android Studio - hence the problem with the two programs having different versions of the same SDK that are incompatible. So, if the installation is made into C:\Android.B4a instead of C:\Android then will the installer set the path in Tools to C:|Android.B4A\platroms\Android-30\android.jar or will I have enter the actual path manually after the installation?

 

[agraham]

Unzip it in a folder such as C:\Android

Actually Erel says this but I agree that it does not make it very clear that the folder name is optional.

I have enter the actual path manually after the installation

Yes.

 

[ColorMan]

Thanks to everyone .... it is working now. I also think that Android Studio still works as well. The updates from B4A does not seem to impact the Studio the way that it did B4A

 

[Erel]

There is no relation between B4A and Android Studio. They will not affect each other.

 

[ColorMan]

But they are related if we follow your original instructions. The folder C:\Android is used by Android Studio. I had to manually copy all of the files that were suggested putting in there because as they were copied, I get, "File already exists do you want to replace?". I installed the latest version of Android studio the week before taking all of the defaults from the installer for the studio and the Android SDK. When I updated B4A, about 95% of the files being copied for the SDK were the same, identical dates and sizes. only a handful were unique. So my current installation of Android Studio and B4A appear to be co-mingled., at least in terms of the Android development tools.

 

[agraham]

There are minor but important differences between the SDKs as used for Android Studio and B4A. Hence the need for each to be installed in its own folder. I think it is unfortunate that Erel chose C:\Android for his example - even though he qualified it with "such as".

 

[MikeSW17]

I don't see Android Studio use C:\Android anywhere.

Android Studio default installation folder is C:\Program Files\Android\Android Studio.
Likewise, Android Studio's SDK is stored in C:\Users\username\AppData\Local\Android\Sdk

Unless the defaults are changed, there (as far as I can see) is NO relationship, interference or shared folders between B4A and Android Studio.
You can install both without worry.

Colorman, As Mike says above, I too have the Android Studio in a different location just as he describes. The only similarity of the two folders is that they have the same name: "Android". I don't have any other information but I thought I'd verify Mike's description above.
