android - 应用程序死于 "Low Memory: No more background processes."

Question

在我的应用程序中，我尝试使用以下 url 启动浏览器:

https://maps.google.com/maps?saddr=indiranagar bangalore&daddr=mgroad bangalore

浏览器启动，本地图加载时，我的应用程序被终止并显示以下 logcat 消息:

我再次尝试使用 www.google.com 从我的应用程序启动浏览器并执行搜索并浏览各种页面并导航回我的应用程序，没有任何问题。我不确定 logcat 上是否遗漏了一些消息。我使用 Android 2.3 操作系统。请有人帮我解决这个问题。提前致谢。

Answer 1

为什么要在 webview 中加载 map ..？你在 map activity 中加载 map 或

使用Intents List: Invoking Google Applications on Android Devices

   String uri = "http://maps.google.com/maps?saddr=" + "9982878"+","+"76285774"+"&daddr="+"9992084"+","+"76286455";
        Intent intent = new Intent(android.content.Intent.ACTION_VIEW, Uri.parse(uri));
        intent.setClassName("com.google.android.apps.maps", "com.google.android.maps.MapsActivity");
        startActivity(intent); 

注:用于显示route你应该使用 map Activity Canvas
