Question

当应用程序没有位置权限并且我打开它时，它会要求许可，在我给它许可后它会崩溃。如果它有权限，它可以顺利运行。

我的位置代码是这个。

if(navigator.geolocation){
  navigator.geolocation.getCurrentPosition(
  function(position){
    // on success
    loadMap(position.coords.latitude, position.coords.longitude);
},
function(e){
  // on error
  loadMap(0,0);
}, {maximumAge: 30000, timeout: 5000, enableHighAccuracy: true})

loadMap函数传递参数，因此我可以创建一个mapbox map。

我正在使用phonegap 6.4.3和cordova 6.4.0并将其编译为带有Android 7.1的虚拟连接5
