【中文标题】缺少 FusedLocationProviderClient.getLastLocation 所需的权限：android.permission.ACCESS_COARSE_LOCATION【英文标题】：Missing permissions required by FusedLocationProviderClient.getLastLocation: android.permission.ACCESS_COARSE_LOCATION 【发布时间】：2020-10-13 09:56:54 【问题描述】：mFusedLocationProviderClient.getLastLocation().addOnCompleteListener 和 mMap.setMyLocationEnabled(true) 这两行都给了我我在标题中提到的错误。我不知道是什么问题..我看了很多视频。但是找不到解决方案警告或说错误，因为有时它的工作或有时应用程序会崩溃

【问题讨论】：
【参考方案1】：在调用mFusedLocationProviderClient.getLastLocation()之前检查ACCESS_COARSE_LOCATION、ACCESS_FINE_LOCATION权限是否被授予，如下图：
if (ContextCompat.checkSelfPermission(this.getApplicationContext(),
FINE_LOCATION) == PackageManager.PERMISSION_GRANTED)
if (ContextCompat.checkSelfPermission(this.getApplicationContext(),
COURSE_LOCATION) == PackageManager.PERMISSION_GRANTED)
mFusedLocationProviderClient.getLastLocation().addOnCompleteListener(new OnCompleteListener < Location > ()
//override methods
);
else
ActivityCompat.requestPermissions(this, permission, LOCATION_PERMISSION_REQUEST_CODE);
else
ActivityCompat.requestPermissions(this, permission,
LOCATION_PERMISSION_REQUEST_CODE);
【讨论】：
我试过了，但 android studio 仍然告诉我：“缺少 FusedLocationProviderClient.requestLocationUpdates 所需的权限：android.permission.ACCESS_COARSE_LOCATION 或 android.permission.ACCESS_FINE_LOCATION” @user15155006 即使添加了checkSelfPermission() 警卫，我也一直收到警告。我的解决方案是编辑 AndroidManifest.xml。这似乎触发了正确的更新以使其消失。【参考方案2】：
“COURSE_LOCATION” - 这是错字^^'
