Question

当尝试在Google地图上显示当前位置时，应用程序显示白色，然后崩溃。底部行的错误表示“呼叫需要许可，可能被用户拒绝”。我正在使用Android 7.0设备。在添加最后一行之前，所有工作都有效。

这是我的MapsActivity.java：

  app.route(window.location.origin + '/sms/outgoing',(req,res)=>{
    let data = JSON.parse(req.body)
    console.log(data) //get {"to":"12345","from":"54321","body":"message"}
 })

这是我的清单：

package com.example.thomas.demomaps;

import android.support.v4.app.FragmentActivity;
import android.os.Bundle;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

public class MapsActivity extends FragmentActivity implements             
OnMapReadyCallback {

private GoogleMap mMap;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maps);
     // Obtain the SupportMapFragment and get notified when the map is ready 
     to be used.
     SupportMapFragment mapFragment = (SupportMapFragment) 
     getSupportFragmentManager()
            .findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);
    }


/**
 * Manipulates the map once available.
 * This callback is triggered when the map is ready to be used.
 * This is where we can add markers or lines, add listeners or move the camera. In this case,
 * we just add a marker near Bristol, UK.
 * If Google Play services is not installed on the device, the user will be prompted to install
 * it inside the SupportMapFragment. This method will only be triggered once the user has
 * installed Google Play services and returned to the app.
 */
@Override
public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;

    // Add a marker in Bristol for Bristol City FC and move the camera
    LatLng Bristol = new LatLng(51.439922, -2.620950);
    mMap.addMarker(new MarkerOptions().position(Bristol).title("Bristol City 
    FC, Ashton Gate Stadium"));
    mMap.moveCamera(CameraUpdateFactory.newLatLng(Bristol));


    mMap.setMyLocationEnabled(true);
   }

}

谢谢！

由于android 6（API级别23），ACCESS_FINE_LOCATION是运行时权限，您需要请求运行时权限，请检查android文档，了解如何执行此操作https://developer.android.com/training/permissions/requesting.html
