호출될 activity

import android.app.Activity; import android.os.Bundle; import android.view.KeyEvent; import android.webkit.WebView; import android.webkit.WebViewClient;
public class Servewebpage extends Activity {
WebView mWebView;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
setContentView(R.layout.servewebview);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true); // 웹뷰에서 자바스크립트실행가능
mWebView.loadUrl("http://m.naver.com");
mWebView.setWebViewClient(new HelloWebViewClient()); // WebViewClient 지정
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack()) {
mWebView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
private class HelloWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
}
호출될 activity의 layout (webview)
<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<WebView
android:id="@+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</LinearLayout>
일단 메인 액티비티에서 아이콘을 클릭하면 webview 로 웹페이지를 호출하는 액티비티를 호출하도록 했는데
소스상 에러는 없지만 메인 액티비티에서 아이콘을 클릭 하고 액티비티를 호출 하지 못하고
unexpectedly 에러 가 뜨면서 종료가 되어 버리네요
manifast 파일에도 액티비티를 추가 했고 검색도 해봤는데
이유를 모르겠습니다 답변 부탁드려요
