は最終的に私はこの問題を解決：

は、ここに私のMainActivity.javaです！ここで

は良いコードです：

import android.content.Intent; 
import android.net.Uri; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.view.KeyEvent; 
import android.view.Window; 
import android.view.WindowManager; 
import android.webkit.URLUtil; 
import android.webkit.WebSettings; 
import android.webkit.WebView; 
import android.webkit.WebViewClient; 

public class MainActivity extends AppCompatActivity { 

private WebView webView; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    this.requestWindowFeature(Window.FEATURE_NO_TITLE); 
    this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); 

    setContentView(R.layout.activity_main); 

    webView = (WebView) findViewById(R.id.webView); 
    WebSettings webSettings = webView.getSettings(); 
    webSettings.setJavaScriptEnabled(true); 
    webSettings.setRenderPriority(WebSettings.RenderPriority.HIGH); 
    webView.loadUrl("http://www.mywebpage.com"); 
    webView.setWebViewClient(new WebViewClient() { 
     @Override 
     public boolean shouldOverrideUrlLoading(WebView view, String url) { 
      if(URLUtil.isNetworkUrl(url)) { 
       return false; 
      } 

      Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url)); 
      startActivity(intent); 
      return true; 
     } 

    }); 
} 

@Override 
public boolean onKeyDown(int keyCode, KeyEvent event) { 
    if (event.getAction() == KeyEvent.ACTION_DOWN) { 
     switch (keyCode) { 
      case KeyEvent.KEYCODE_BACK: 
       if (webView.canGoBack()) { 
        webView.goBack(); 
       } else { 
        finish(); 
       } 
      case KeyEvent.KEYCODE_MENU: 
       webView.loadUrl("javascript:open_menu()"); 
      return true; 
     } 

    } 
    return super.onKeyDown(keyCode, event); 
}
