Android Question Error NoClassDefFoundError and DefaultHttpClient

[AlpVir]

I cannot resolve this error which occurs immediately when I try to compile in debug mode. I searched in vain for "NoClassDefFoundError" and/or "DefaultHttpClient", without solving the problem.
In release mode, however, the app installs itself but does not start.

Thanks in advance.

Post your code.
Looks like you are not using okhttputils.
Everything else we just can FISH. I hate fishing...

Posting the code seems very complicated to me, it involves numerous Activities and modules. I try to provide some other elements. The app works (always in debug mode) with Android 8. It produces that error with Android 11.
I use various libraries, including OkHttp 1.31, AndroidResources 1.6, ContentResolver 1.5, Core 11.00, JavaObject 2.06, Reflection 2.4, RuntimePermissione 1.12, SQL 1.5, etc etc
The app saves files in File.dirInternal, not in File.DirRootExternal.
Javac.exe is C:\Java\jdk-11.0.1\bin\javac.exe
Android.jad is C:\Android\platforms\android-30\android.jar
Five modules are ContactUtils.bas, CustomListView.bas, HttpUtils2Service, HttpJob.bas, FileProvider.bas.
This is the manifest file :

AddManifestText(
<uses-sdk android:minSdkVersion="5" android:targetSdkVersion="29"/>
<supports-screens android:largeScreens="true"
android:normalScreens="true"
android:smallScreens="true"
android.hardware.sensor.orientation="true"
android:anyDensity="true"/>)
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
SetApplicationAttribute(android:theme, "@android:style/Theme.Holo.Light")
SetApplicationAttribute(android:allowBackup, "false")
AddPermission(android.permission.READ_PROFILE)
AddManifestText(<uses-feature android:name="android.hardware.location.gps"/>)
AddReplacement(android.intent.action.GPSSERVICE, unused_action)
SetActivityAttribute(main, android:windowSoftInputMode, adjustPan|stateHidden)
CreateResourceFromFile(Macro, Core.NetworkClearText)
AddApplicationText(
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="$PACKAGE$.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths"/>
</provider>
)
CreateResource(xml, provider_paths,
<files-path name="name" path="shared" />
)
AddPermission("android.permission.READ_CONTACTS")
AddPermission("android.permission.GET_ACCOUNTS")
AddPermission("android.permission.READ_PHONE_STATE")

Five modules are ContactUtils.bas, CustomListView.bas, HttpUtils2Service, HttpJob.bas, FileProvider.bas.

Very bad to use these modules...

Switch to OkHttpUtils2 library, xCustomListView library and FileProvider library.
