.RuntimeException: ComponentInfo java.lang.ClassNotFoundException etkinliği başlatılamadı: "moveitech.com.MainActivity" [yinelenen] sınıfı bulunamadı

Question

Bu konuyla ilgili internette bulunan birçok şeyi denedim ama benim için hiçbir şey çalışmıyor. benim için gerçekten telaşlı. etkinlik adı manifestte doğru yazılmıştır, ayrıca paket adı da doğru ve ayrıca temizlemeyi ve yeniden oluşturmayı denedim.

Manifest dosyam aşağıdadır

<?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>

Ana aktivite kodu aşağıdadır

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;
            }
        };
  }

.Java ve .xml dosyanızı yeniden adlandırmayı deneyin ve Manifest.xml dosyasını eklemeyi unutmayın.
