问题本地app跳转到第三方app地图进行导航获取不到第三方地图是否安装。
解决
1.添加包名
This can be done by adding a queries element in the Android manifest.在app下的manifest文件内manifest标签下添加queries标签设置包名 queriespackage android:namecom.autonavi.minimap /package android:namecom.baidu.BaiduMap /package android:namecom.tencent.map //queries
2.MapUtil工具类

3.调用 MapUtil. openGaoDeNavi(Context context, double slat, double slon, String sname, double dlat, double dlon, String dname)工具类可以直接用SelectDialog就是一个底部弹窗。
