缺少 FusedLocationProviderClient.getLastLocation 所需的权限：android.permission.ACCESS_COARSE_LOCATION

Question

mFusedLocationProviderClient.getLastLocation().addOnCompleteListener 和 mMap.setMyLocationEnabled(true) 这两条线都给我错误，我在标题中提到了。我不知道是什么问题。我看了很多视频。但是找不到此警告的解决方案或说错误，因为有时它的工作或有时应用程序会崩溃

Answer 1

在调用 mFusedLocationProviderClient.getLastLocation() 之前检查 ACCESS_COARSE_LOCATION、ACCESS_FINE_LOCATION 权限是否被授予，如下所示：

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);
}

Answer 2

"COURSE_LOCATION" - 这是错字 ^^'

缺少 FusedLocationProviderClient.getLastLocation 所需的权限：android.permission.ACCESS_COARSE_LOCATION

Missing permissions required by FusedLocationProviderClient.getLastLocation: android.permission.ACCESS_COARSE_LOCATION
