缺少 GoogleMap.setMyLocationEnabled 所需的权限：android.permission.ACCESS_COARSE_LOCATION 或 android.permission.ACCESS_FINE_LOCATION

Question

尝试使用地理围栏位置，但在选择地理围栏区域时应用程序崩溃。 ACCESS_COARSE_LOCATION 和 ACCESS_FINE_LOCATION 权限已在清单文件中声明，但在启动应用程序时，它不会请求允许该权限。

代码

  private void enableUserLocation(){
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED){
            mMap.setMyLocationEnabled(true);

        }
        else {
            if(ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.ACCESS_FINE_LOCATION)){
                ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, FINE_LOCATION_ACCESS_REQUEST_CODE);
            }
            else {
                if(ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.ACCESS_FINE_LOCATION)) {
                    ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, FINE_LOCATION_ACCESS_REQUEST_CODE);
                }
            }
        }

    }

AndroidManifestXml 代码：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="com.example.quarantinemonitoringapp" >

    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />

肯先生。 我目前无法设置具有最低要求的项目来获得此错误。 但我相信您需要像使用 ACCESS_FINE_LOCATION 一样检查 ACCESS_COARSE_LOCATION 权限
