.RuntimeException: Tidak dapat membuat instance aktivitas ComponentInfo java.lang.ClassNotFoundException: Tidak menemukan kelas "moveitech.com.MainActivity" [duplikat]

Question

Saya telah mencoba banyak hal yang tersedia di internet mengenai masalah ini tetapi tidak ada yang berhasil untuk saya. itu sangat sibuk bagi saya. nama aktivitas ditulis dengan benar di manifes juga nama paket sudah benar dan saya juga mencoba membersihkan dan membangun kembali.

Berikut ini adalah file manifes saya

<?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>

berikut ini adalah kode aktivitas utama

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;
            }
        };
  }

ini adalah kesalahannya

Coba ganti nama file .java dan .xml Anda dan jangan lupa tambahkan di file Manifest.xml.
