Android Question Error compiling

[Alberto Michelis]

Hi, Ive installed the new B4A to a new PC following all instructions, copy a project that compiles ok in another PC and get the following error:

Uncaught translation error: com.android.dx.cf.code.SimException: invalid opcode ba (invokedynamic requires --min-sdk-version >= 26)

Ive set the minsdkversion to 26 in the manifest but the error persists.
How to solve it?
Thanks

Thanks Edgar
Ive done all of this post and nothing, cant compile.
How can I post a list of the referenced libraries.?

How can I post a list of the referenced libraries.?

- Make a screenshot?
- Look at the B4A File; they are listed here if you look at this file with notepad++

What B4A Version are you using?
Did you REMOVED/DELETED the old SDK and installed a new one? Starting from B4A 10.7 (i think) it is mandatory to install a new (changed) SDK.
See https://www.b4x.com/b4a.html for detailed instructions. Follow carefully.

Did you click on menu Tools > Jetifier (Android X) ?

 

[Alberto Michelis]

No, what does it do?
Theres nothing about it in the installation instructions.
What must I do? I click on it an a window with *.jar list appears.

It jetifies old libraries created before Android X... Do it and try to recompile. Let us know if it works.

After doing what @DonManfred has suggested in previous message do Jetify also because you might have some old libraries that require you to do it.

Assuming that you are using a new SDK with B4A v11 then this error is related to an old library that needs to be updated.
Create a new project and add the libraries until you find the one that causes the problem. It will not be any of the internal libraries.
