I have a problem using PythonInterpreter in Android Studio somehow it keeps crashing the app and I don't understand the error and how to solve it.
Ich habe ein Problem den PythonInterpreter in Android Studio zu nutzen, irgendwie sorgt alleine die Initialisierung einer PythonInterpreter variable für Probleme ohne das es mir Syntax error anzeigt. Ich habe allerdings keine Ahnung wie ich das Problem lösen kann.

Der error:

Java: 
Process: com.example.signlanguageinterpreter, PID: 11601
java.lang.NoClassDefFoundError: Failed resolution of:

Der Code sieht so aus


Java: 
import org.python.core.PyObject;
import org.python.util.PythonInterpreter;
import java.util.HashMap;

public class MainActivity extends AppCompatActivity {
    HashMap model_dict = new HashMap();
    PythonInterpreter interpreter;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        interpreter = new PythonInterpreter(); // hier crashed das Programm
        interpreter.execfile("/home/PycharmProjects/SignLanguage_State2/inference_classifier.py");

        PyObject getAtrsFunc = interpreter.get("main");
        PyObject funcRes = getAtrsFunc.__call__();

        model_dict = (HashMap) funcRes.__tojava__(HashMap.class);

    }
}

und falls es wichtig ist ich hatte vorher einen Fehler der so aussah:

8
Code: 
files found with path 'META-INF/INDEX.LIST'.
Adding a packagingOptions block may help, please refer to
https://developer.android.com/reference/tools/gradle-api/8.0/com/android/build/api/dsl/ResourcesPackagingOptions
for more information

den ich dann gelöst habe in dem ich das folgende snippet zu meinem build.gradle file hinzugefügt habe:

Java: 
packagingOptions {
        pickFirst "META-INF/INDEX.LIST"
        pickFirst "META-INF/io.netty.versions.properties"
    }


Meine Java version ist 1.8 und die der android Sdk ist 33, falls das relevant sein sollte.

Vielen Dank schonmal für jede Hilfe und Idee wie ich das lösen kann.
