.RuntimeException: impossible d'instancier l'activité ComponentInfo java.lang.ClassNotFoundException: classe "moveitech.com.MainActivity" [duplicate] introuvable

Question

J'avais essayé beaucoup de choses disponibles sur Internet concernant ce problème mais rien ne fonctionne pour moi. c'est vraiment mouvementé pour moi. Le nom de l'activité est correctement écrit dans le manifeste et le nom du package est correct et j'avais également essayé de nettoyer et de reconstruire.

Voici mon fichier manifeste

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="moveitech.com">

<uses-permission android:name="android.permission.INTERNET"/>
<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme"
    tools:ignore="GoogleAppIndexingWarning">
    <activity android:name="moveitech.com.MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

</manifest>

Voici le code d'activité principal

package moveitech.com;

import androidx.annotation.NonNull;
import androidx.appcompat.app.AppCompatActivity;
import androidx.fragment.app.Fragment;

import android.os.Bundle;
import android.view.MenuItem;

import com.google.android.material.bottomnavigation.BottomNavigationView;

import retrofit2.Call;

public class MainActivity extends AppCompatActivity {

private BottomNavigationView bottomNavigationView;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    bottomNavigationView= findViewById(R.id.bottomNavigationView);
    bottomNavigationView.setOnNavigationItemSelectedListener(navigationItemSelectedListener);

  

   getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,
   newSearch_f()).commit();




  }



   private BottomNavigationView.OnNavigationItemSelectedListener navigationItemSelectedListener=
        new BottomNavigationView.OnNavigationItemSelectedListener() {
            @Override
            public boolean onNavigationItemSelected(@NonNull MenuItem item) {
                Fragment selectedFragment =null;
                switch (item.getItemId())
                {
                    case R.id.search:
                        selectedFragment= new Search_f();
                        break;
                    case R.id.URL:
                        selectedFragment= new url_search();
                        break;
                    case R.id.setting:
                        selectedFragment= new Setting_f();
                        break;
                }
                

   getSupportFragmentManager().beginTransaction()
  .replace(R.id.fragment_container,selectedFragment).commit();
                return true;
            }
        };
  }

Essayez de renommer votre fichier .java et .xml et n'oubliez pas d'ajouter le fichier Manifest.xml.
