I solved this issue by adding some code in AppActivity.java

package org.cocos2dx.cpp;

import org.cocos2dx.lib.Cocos2dxActivity;

public class AppActivity extends Cocos2dxActivity {
}

to…

package org.cocos2dx.cpp;

import org.cocos2dx.lib.Cocos2dxActivity;
import org.cocos2dx.lib.Cocos2dxGLSurfaceView;

public class AppActivity extends Cocos2dxActivity {
    public Cocos2dxGLSurfaceView onCreateView() {
        Cocos2dxGLSurfaceView glSurfaceView = new Cocos2dxGLSurfaceView(this);
        glSurfaceView.setEGLConfigChooser(5, 6, 5, 0, 16, 8);
        
        return glSurfaceView;
    }
}
