Android 通过Webview登录Linkedin时卡住

实际上，我的应用程序是通过linkedin应用程序和webview使用linkedin登录的。使用linkedin登录正常，但如果linkedin应用程序不可用，我将使用webview处理登录。这也很好，但今天它突然陷入了一些代码异常。我在我的Linkedin对话类中获得了空访问令牌，所以我喜欢放置try-catch，但之后它将显示空白的webview，我不知道该怎么做。这是我的linkedin对话代码

public class LinkedinDialog extends Dialog
{
private ProgressDialog progressDialog = null;

public static LinkedInApiClientFactory factory;
public static LinkedInOAuthService oAuthService;
public static LinkedInRequestToken liToken;
private WebView mWebView;
private Context mContext;

public LinkedinDialog(Context context, ProgressDialog progressDialog) 
{
    super(context);
    mContext = context;
    this.progressDialog = progressDialog;
}

@Override
protected void onCreate(Bundle savedInstanceState) 
{
    requestWindowFeature(Window.FEATURE_NO_TITLE);// must call before super.
    super.onCreate(savedInstanceState);
    setContentView(R.layout.ln_dialog);
    setWebView();
}

/**
 * set webview.
 */
private void setWebView()
{
    mWebView = (WebView) findViewById(R.id.webkitWebView1);
    mWebView.getSettings().setJavaScriptEnabled(true);
    try {
        LinkedinDialog.oAuthService = LinkedInOAuthServiceFactory.getInstance().createLinkedInOAuthService(AppConstants.LINKEDIN_CONSUMER_KEY, AppConstants.LINKEDIN_CONSUMER_SECRET);
        LinkedinDialog.factory = LinkedInApiClientFactory.newInstance(AppConstants.LINKEDIN_CONSUMER_KEY, AppConstants.LINKEDIN_CONSUMER_SECRET);
        LinkedinDialog.liToken = LinkedinDialog.oAuthService.getOAuthRequestToken(AppConstants.OAUTH_CALLBACK_URL);

        mWebView.loadUrl(LinkedinDialog.liToken.getAuthorizationUrl());
        mWebView.setWebViewClient(new HelloWebViewClient());

        mWebView.setPictureListener(new PictureListener() {
            @Override
            public void onNewPicture(WebView view, Picture picture) {
                if (progressDialog != null && progressDialog.isShowing()) {
                    progressDialog.dismiss();
                }

            }
        });
    }catch (ExceptionInInitializerError e){
        AppLogs.printLogs("ExceptionInInitializerError :: " , " err ::");
        LinkedinDialog.this.dismiss();
        mWebView.goBack();
    }catch (NoClassDefFoundError ex){
        AppLogs.printLogs("NoClassDefFoundError :: " , " err ::");
        ex.printStackTrace();
        LinkedinDialog.this.dismiss();
        mWebView.goBack();
    }catch (Exception ee){
        LinkedinDialog.this.dismiss();
        mWebView.goBack();
    }
}

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if(event.getAction() == KeyEvent.ACTION_DOWN){
        switch(keyCode)
        {
            case KeyEvent.KEYCODE_BACK:
                    if (mWebView.canGoBack()) {
                        mWebView.goBack();
                    } else {
                        cancel();
                    }

                return true;
        }

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

class HelloWebViewClient extends WebViewClient 
{
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) 
    {
        if (url.contains(AppConstants.OAUTH_CALLBACK_URL))
        {
            Uri uri = Uri.parse(url);
            String verifier = uri.getQueryParameter("oauth_verifier");

            cancel();

            for (OnVerifyListener d : listeners) 
            {
                // call listener method
                d.onVerify(verifier);
            }
        } 
        else if (url.contains("https://www.google.co.in/")) 
        {
            cancel();
        } 
        else 
        {
            Log.e("LinkedinSample", "url: " + url);
            view.loadUrl(url);
        }

        return true;

所有jar依赖项：

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.2.0'
compile project(':linkedin-sdk')
compile files('libs/linkedin-j-android.jar')

第一次单击时收到的异常：

W/System.err﹕ at com.google.code.linkedinapi.client.oauth.LinkedInOAuthServiceImpl.getOAuthProvider(LinkedInOAuthServiceImpl.java:230)

然后我按“上一步”按钮再次登录，然后出现如下新异常：

W/System.err﹕ java.lang.NoClassDefFoundError: com.google.code.linkedinapi.client.constant.LinkedInApiUrls

我自己解决了这个问题…我只清除了构建包装，然后删除了linkedin的现有jar文件，比如linkedin-j、路标核心、，commons编解码器并再次导入相同的文件，然后构建项目…现在它运行良好。

是否有可能发布错误日志或stacktrace？@jagmohan请检查我的更新问题我自己解决了这个问题…我只清除了构建包装，然后删除了linkedin的现有jar文件，如linkedin-j、signpost core、，commons编解码器并再次导入相同的文件，然后构建项目…现在它运行良好。很高兴听到。继续
