1、判断是否安装有高德APP

//高德APP
private 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
                    openGaodeMapToGuide();//打开高德APP
                } else {//否则 打开浏览器
                    openBrowserToGuide();
                }

    private void openGaodeMapToGuide() {
        Intent intent = new Intent();
        intent.setAction(Intent.ACTION_VIEW);
        intent.addCategory(Intent.CATEGORY_DEFAULT);
        Log.i("高德定位：","经度："+currLocationY+" ,纬度："+currLocationX);
        if (currLocationX == 0.0 || currLocationY == 0.0){
            url = "androidamap://route?sourceApplication=amap&dlat="+locationX+"&dlon="+locationY+"&dname="+storeName+"&dev=0&t=1";
        }else {
            url = "androidamap://route?sourceApplication=amap&slat="+currLocationX+"&slon="+currLocationY
                +"&dlat="+locationX+"&dlon="+locationY+"&dname="+storeName+"&dev=0&t=1";
        }



        Uri uri = Uri.parse(url);
        //将功能Scheme以URI的方式传入data
        intent.setData(uri);

        startActivity(intent);
    }


    /**

     */
    private void openBrowserToGuide() {
        String url = "http://uri.amap.com/navigation?to=" + locationY + "," + locationX + "," +
                storeName + "&mode=car&policy=1&src=mypage&coordinate=gaode&callnative=0";
        Uri uri = Uri.parse(url);
        Intent intent = new Intent(Intent.ACTION_VIEW, uri);
        startActivity(intent);
    }





    public void initPackageManager(){
        List<PackageInfo> packageInfos = mPackageManager.getInstalledPackages(0);
        if (packageInfos != null) {
            for (int i = 0; i < packageInfos.size(); i++) {

            }
        }
    }

    /**
     * 判断有无安装高德
     * @return
     */
    public boolean haveGaodeMap(){
        initPackageManager();
        return mPackageNames.contains(GAODE_PACKAGE_NAME);
    }
