我正在写Phonegap的第一个应用程序,我一直在
Android设备上测试它.我相信我已经给予了适当的许可:
<uses-permission android:name="android.permission.INTERNET" />
但地图没有显示出来.我试图通过网络服务获得经度和经度,并使用它在Google地图上放置一个标志.我相信问题实际上是因特网访问,就好像我通过Visual Studio作为网站运行,服务返回坐标并显示地图.但是,当编译应用程序并且该应用程序webview内部运行该网站时,不会返回坐标,也不会显示任何地图.
我还添加了一个表来显示返回的坐标,它们再次显示在浏览器中,但在正在运行的应用程序中是空白的.有谁知道为什么webview无法连接到互联网并返回所需的数据?我删除了Web服务的实际地址,但我知道这很好,因为它在浏览器中工作.
