Android Question Compile App targeted to old devices

[incendio]

Hi guys,

I have users who still use Android 4. With new B4A, when compile, I got an error in OkHttpUtils2 Library ver 3.

Is there a solution for this problem?

In manifest editor, minSdkVersion="5" android:targetSdkVersion="26"

Can you post more error? I used but without error, OkHttpUtils2 you can use with its source code

Here are the error message :

On newer Android, like Android 9, no errors.

You should downgrade to the version of b4a before this version.

I have downgraded B4A to version 11.5 where it worked before, but seem the library already affected.
In version 11.5, OkHttpUtils2 already version 3 although I have uninstalled ver 11.8.

Go to C:\Program Files (x86)\Anywhere Software\Basic4android and open B4A.exe if yo didn't delete the files else re-install ?

Yes, that was exactly I did.

I have 2 version B4A installed on same computer, ver 11.5 and 11.8.
Run ver 11.5 from C:\Program Files (x86)\Anywhere Software\Basic4android, but the library already ver 3.0.

Seem that can't run both version on the same computer.

I think if uninstall both version then reinstall ver 11.5 could solve the problem, but will loose new features from latest B4A version.

See this thread:

Latest OkHttpUtils working with Android 4?

Hi all. I have an old widget of mine running on an Android 4.4 device. I have to update it now, but I recall something changed in the underlying lib which causes current OkHttpUtils working from Android 5 up. So my question is: which is the latest B4A version sporting a copy of OkHttpUtils...

You can copy some older libs for the HTTP stuff and still use the new version of B4X

Still got an error. Switching to that thread for more question.
