我现在对oAuth有点问题。它是一个我一直在搞乱的示例代码，它在2.2上完美运行但是当我在4.1上测试时，我得到了强制关闭错误。
下面是我一直在搞乱的示例代码：
public class OAuthAccessTokenActivity extends Activity {
final String TAG = getClass().getName();
private SharedPreferences prefs;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.i(TAG, "Starting task to retrieve request token.");
this.prefs = PreferenceManager.getDefaultSharedPreferences(this);
// new OAuthRequestTokenTask(this).execute();
}
@Override
protected void onResume() {
super.onResume();
WebView webview = new WebView(this);
webview.getSettings().setJavaScriptEnabled(true);
webview.setVisibility(View.VISIBLE);
setContentView(webview);
String authorizationUrl = new GoogleAuthorizationRequestUrl(
OAuth2ClientCredentials.CLIENT_ID,
OAuth2ClientCredentials.REDIRECT_URI,
OAuth2ClientCredentials.SCOPE).build();
/* WebViewClient must be set BEFORE calling loadUrl! */
webview.setWebViewClient(new WebViewClient() {
@Override
public void onPageStarted(WebView view, String url, Bitmap bitmap) {
System.out.println("onPageStarted : " + url);
}
@Override
public void onPageFinished(WebView view, String url) {
if (url.startsWith(OAuth2ClientCredentials.REDIRECT_URI)) {
try {
if (url.indexOf("code=") != -1) {
String code = extractCodeFromUrl(url);
AccessTokenResponse accessTokenResponse = new GoogleAuthorizationCodeGrant(
new NetHttpTransport(),
new JacksonFactory(),
OAuth2ClientCredentials.CLIENT_ID,
OAuth2ClientCredentials.CLIENT_SECRET,
code, OAuth2ClientCredentials.REDIRECT_URI)
.execute();
CredentialStore credentialStore = new SharedPreferencesCredentialStore(prefs);
credentialStore.write(accessTokenResponse);
view.setVisibility(View.INVISIBLE);
startActivity(new Intent(OAuthAccessTokenActivity.this,AgentPortalActivity.class));
} else if (url.indexOf("error=") != -1) {
view.setVisibility(View.INVISIBLE);
new SharedPreferencesCredentialStore(prefs).clearCredentials();
startActivity(new Intent(OAuthAccessTokenActivity.this,LatitudeApiSample.class));
}
} catch (IOException e) {
e.printStackTrace();
}
}
System.out.println("onPageFinished : " + url);
}
private String extractCodeFromUrl(String url) {
return url.substring(
OAuth2ClientCredentials.REDIRECT_URI.length() + 7,
url.length());
}
});
webview.loadUrl(authorizationUrl);
}
}
继承我的logcat：

似乎崩溃是在第95行，即“.execute（）;”
任何人都可以就我应该做些什么给我一些建议吗？谢谢！
