Android中直接打开高德APP进行导航

1、判断是否安装有高德APP

1//高德APPprivate PackageManager mPackageManager;private static List<String> mPackageNames = new ArrayList<>();private static final String GAODE_PACKAGE_NAME = "com.autonavi.minimap";private static final String BAIDU_PACKAGE_NAME = "com.baidu.BaiduMap";/*private double currLocationX = 39.9076860000;private double currLocationY = 116.4012450000;private double locationX = 40.0836620000;private double locationY = 116.4127900000;private String storeName = "北京饭店";*/private double currLocationX;//起点 纬度private double currLocationY;//起点 经度private double locationX;//终点 纬度private double locationY;//终点 经度private String storeName;//地点名称 if(haveGaodeMap()){//如果安装高德APP
2                    openGaodeMapToGuide();//打开高德APP
3                } else {//否则 打开浏览器
4                    openBrowserToGuide();
5                }
