更新: 不推荐使用GCM,请使用FCM

如果我的应用程序处于打开状态,如何刷新接收gcm推送通知的活动.我有一个活动,其中包含从服务器填充数据的列表视图.我想刷新我的活动(这里再向listview添加一个项目),如果我收到gcm推送通知(其中还包含一些数据).

• 另一种方法是添加定期执行服务器请求并更新列表适配器数据的计时器,但我不想要这些,因为它将占用大量资源.
• 我是否需要添加广播接收器,它将在接收gcm push时触发,进一步请求更新的服务器数据并更新我的活动UI？

亲爱的评论员,请仔细阅读问题,我只需刷新列表(如果应用程序已打开且特定活动已打开),否则不需要相同.

我在pom xml文件中的插件标记中收到错误.错误发生在groupId之前的插件标记上.

错误: -

Plugin execution not covered by lifecycle configuration:com.jayway.maven.plugins.android.generation2:android-maven-plugin:3.8.2:consume-aar (execution: default-consume-aar, phase: compile)

任何人都知道如何解决这个问题.下面提到的是pom.xml文件内容

当maven构建我的pom.xml文件时,我收到编译失败错误.

编译错误是:

error reading C:\Users\amrit\.m2\repository\com\google\android\support-v4\r6\support-v4-r6.jar; invalid LOC header (bad signature).

有谁知道如何解决这个问题？以下是我的pom.xml档案:

我无法解决这个问题.任何形式的帮助将不胜感激.

我是Google Project的新手,我必须在我的项目中集成Google Calendar和Google Task.为此,我正在考虑[ https://developers.google.com/google-apps/calendar/instantiate][1].我已添加:

google play services as library google-api-services-calendar-v3-rev81-java-1.18.0-rc.

但它显示错误"com.google.api.client.auth.oauth2.draft10.AuthorizationRequestUrl类型无法解析.它是从所需的.class文件间接引用的"

这是我的代码:

    String clientId = "YOUR_CLIENT_ID";
    String clientSecret = "YOUR_CLIENT_SECRET";

    // Or your redirect URL for web based applications.
    String redirectUrl = "urn:ietf:wg:oauth:2.0:oob";
    String scope = "https://www.googleapis.com/auth/calendar";

    // Step 1: Authorize -->
    String authorizationUrl = new GoogleAuthorizationRequestUrl(clientId,
            redirectUrl, scope).build();

    // Point or redirect your user to the authorizationUrl.
    System.out.println("Go to the following link in your browser:");
    System.out.println(authorizationUrl);

    // Read the authorization code from the standard input stream.
    BufferedReader …

当我添加"this.requestWindowFeature(Window.FEATURE_NO_TITLE);"到活动中时，IDE会变红“窗口”字样，并在工具提示上通过“无法解析符号“窗口””警告我

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.activity_splash_screen);
