Android Question Needing okHTTP support for Android 4.x

[JakeBullet70]

Hi all.

Working on an app that will NEVER see the play store and will be open source, GITHUB style. Anyway i want it to run on Android 4.x and above.
Point being to re claim all those old Android devices every one just tosses in a drawer or the garbage dump and never use again.

Am using the latest B4A and ran into issues where some libraries need a a newer API then the old phones . tablets have.
1st problem is OkHttpClient. It wants API level 21, I believe I need 16.
Question, Should I go back a B4A version to be compatible with older devices? Or is there a better what to handle it.

<uses-sdk android:minSdkVersion="14" android:targetSdkVersion="30"/>

in this way your app will already be from android version 4.0 or major

OkHttp - Replaces the Http library

OkHttpUtils2 source code: [B4X] OkHttpUtils2 / iHttpUtils2 / HttpUtils2 source code It is included as an internal library. Usage: [B4X] OkHttpUtils2 with Wait For The current Http library is based on the Android version of Apache HttpClient. Google has stopped updating this SDK a long time ago...

This library requires Android 2.3+.

This library requires Android 2.3+.

The newest okhttp Library (installed with the newest Ide) requires Android 5+.

Overview - OkHttp

Square’s meticulous HTTP client for the JVM, Android, and GraalVM

Requirements¶​

OkHttp works on Android 5.0+ (API level 21+) and Java 8+.
OkHttp depends on Okio for high-performance I/O and the Kotlin standard library. Both are small libraries with strong backward-compatibility.

Right dear Don, the last release work 5.0+
Anyway maybe it can help you

okHttpUtils 2.95 and Java 11

Hi All. jokHttpsUtils 2.95 gives problems when run with Java 11. Changing (in B4J 8.80 by replacing the jokHttpsUtils file from 2.95 with the one that was present in B4J 8.50 everything returns to normal). The question is: Should only Java 14 or > be used from version B4J 8.80 ? Any suggestion...

you can replace the okhttp file with the 4.X compatible version

https://mvnrepository.com/artifact/com.squareup.okhttp3/okhttp

but i don't know if there are specific contraindications

OkHttp 3.13 Requires Android 5+

Today we’re releasing OkHttp 3.13

What about Android 4.x?​

Google’s shows that ~11% of the devices that visited the Play Store in October 2018 were running Android 4.x. We’ve created a branch, OkHttp 3.12.x, to support these devices. Should we encounter any severe bugs or security problems we’ll backport the fixes and release. We plan to maintain this branch through December 31, 2020.

B4A 11.2 link: https://www.b4x.com/android/files/B4A_11_2.exe

It should include the older OkHttp / OkHttpUtils2 libraries.
You can use these libraries with newer versions of B4A.

Sorry guys - gals, forgot to post this. I did this last week or so and spaced out updating the thread.
These are the internal libs that need to be replaced for all HTTP stuff to work with Android 4.x
Grab them from the download above @Erel posted.

All is Good!
