Android Question Error sdk-version>=26

[Peekay]

I get these errors when I run my B4A project:

Compiling generated Java code. (0.03s)
Convert byte code - optimized dex. Error
Uncaught translation error: com.android.dx.cf.code.SimException: invalid opcode ba (invokedynamic requires --min-sdk-version >= 26)

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

I think the error is in the manifest file which has the following code:

AddManifestText(<uses-sdk android:minSdkVersion="5" android:targetSdkVersion="26"/><supports-screens android:largeScreens="true" android:normalScreens="true" android:smallScreens="true" android:anyDensity="true"/>)
AddManifestText(<uses-feature android:name="android.hardware.telephony" android:required="false" />)

Any help will be appreciated.

Thanks JohnC,
But I am not even using a media player or video player in my app.
I took Erel's advice when the errors stated in the introduction of this thread came up when I compiled it, and this was his advice that I should desugar.
Now I doubt that advice and suspect that something else must be wrong.
However, I think my best way out is to start the app on a clean sheet and see what happens.
Thanks for your patience. I appreciate.

OK, I understand where you are coming from because the page that Erel pointed to starts off with "Some of the new Android libraries use Java 8 features. Android doesn't natively support those features so they must be removed (desugared) at some point."

So, basically you need to find out what lib is causing this compile error - probably by unselecting one lib at a time and remarking out it's related code in the project.

Here are some clues I have found, but I do not understand them:

The desugar situation is complicated. Android Gradle Plugin (used in Android Studio) once incorporated desugar_deploy.jar to deal with desugaring. Now Google introduced d8 and quickly abandoned standalone desugar tool. Since Google has already removed desugar_deploy from Android Gradle Plugin setup, we will have to do the same.

After hours of struggling, I solved it by including the following within app/build.gradle:
android {
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}

I have established that the cause of the error is the dexer. Opening another thread for that.
