Android Question App crashes when compiled with targetSdkVersion 28 vs 26

[biometrics]

I've updated to the latest B4X 9.80, Oracle JDK 8u241, Command line tools, resources.zip, Configure Paths updated.

It works fine with targetSdkVersion 26 but at 28 I get this log:

Any ideas?

android.jar / targetSdkVersion / minSdkVersion

Add this to your manifest

AddApplicationText(
<uses-library
      android:name="org.apache.http.legacy"
      android:required="false" />
)

Thanks Don. My Googling of the error led me to add:

<uses-library android:name="org.apache.http.legacy" android:required="false" />

In AddManifestText after:

<uses-sdk android:minSdkVersion="9" android:targetSdkVersion="28"/>

but that didn't work. Your command (outside of AddManifestText) works.

You shouldn't use the old HttpUtils2. Switch to OkHttpUtils2.

You shouldn't use the old HttpUtils2. Switch to OkHttpUtils2.

Is it a direct replacement? I'd like to avoid any major changes to the app. What will the implication be if I remain on HttpUtils2 for a while?

 

[DonManfred]

there is no problem in switching to okhttputils2
