Wikitude SDK - 标记未显示在摄像机视图中

标签: android marker wikitude

我在Wikitude中按照POI示例创建了一个简单的应用程序。当我运行应用程序时,摄像机视图上没有绘制标记。我也有样本POI应用程序的相同问题。我在“onLocationChangedFn”和“createMarkerAtLocation”函数中的js文件中放了一些JS警报,并且警报正确显示(希望这意味着正确调用了javascript函数。但仍然标记不会显示在地理位置。

我在Eclipse的logcat中看到以下内容:

我在上面的日志中看到两个问题:一个关于"unimplemented OpenGL ES API",另一个关于"Uncaught TypeError: Property 'onLocationChanged' "

那些标记没有出现的原因是什么?如何修复这些并在屏幕上显示标记。请帮忙......

由于执行JavaScript代码时出错,会记录Uncaught TypeError输出。如果您发布代码,我们可能会告诉您错误。

要检查的一些事项:

  1. 是正确包含的architect.js
  2. 您是否正确使用了API(例如忘记添加命名空间AR
  3. 使用SDK附带的ade.js在桌面浏览器上进行测试(它提供了更好的调试体验)。
  4. 免责声明:我为Wikitude工作。

当我遇到这个问题时,那是因为我错过了添加这些功能:

public class SyncAdapter extends AbstractThreadedSyncAdapter {
    private final AccountManager mAccountManager;

    public SyncAdapter(Context context, boolean autoInitialize) {
        super(context, autoInitialize);
        mAccountManager = AccountManager.get(context);
    }

    @Override
    public void onPerformSync(Account account, Bundle extras, String authority, ContentProviderClient provider, SyncResult syncResult) {
        Log.d("udinic", "onPerformSync for account[" + account.name + "]");
        try {
            // TODO Updating local tv shows

        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
