How to import awt package in android?

Answer 1

Please kindly help me,how to import awt package in android

You can't. Presumably, you are using some library that is designed for use with desktop Java, not Android. Find some replacement library that is designed for use with Android.

Not allowed to comment yet so this is not answer, but perhaps someone can add it as a comment...

Here's the stack trace sample requested. As can be seen this is Google code for oauth:

    java.lang.NoClassDefFoundError: Failed resolution of: Ljava/awt/Desktop;
    at com.google.api.client.extensions.java6.auth.oauth2.AuthorizationCodeInstalledApp.browse(AuthorizationCodeInstalledApp.java:129)
    at com.google.api.client.extensions.java6.auth.oauth2.AuthorizationCodeInstalledApp.onAuthorization(AuthorizationCodeInstalledApp.java:113)
    at com.google.api.client.extensions.java6.auth.oauth2.AuthorizationCodeInstalledApp.authorize(AuthorizationCodeInstalledApp.java:81)

And the code that's trying to talk to the Desktop class:

   /**
   * Open a browser at the given URL using {@link Desktop} if available, or alternatively output the
   * URL to {@link System#out} for command-line applications.
   *
   * @param url URL to browse
   */
  public static void browse(String url) {
    Preconditions.checkNotNull(url);
    // Ask user to open in their browser using copy-paste
    System.out.println("Please open the following address in your browser:");
    System.out.println("  " + url);
    // Attempt to open it in the browser
    try {
      if (Desktop.isDesktopSupported()) {
        Desktop desktop = Desktop.getDesktop();
        if (desktop.isSupported(Action.BROWSE)) {
          System.out.println("Attempting to open that address in the default browser now...");
          desktop.browse(URI.create(url));
        }
      }
