android - 错误权限 ACCESS_FINE_LOCATION

Question

我正在使用权限 ACCESS_FINE_LOCATION 但是当运行时出现错误:需要 ACCESS_FINE_LOCATION 权限为什么？

提前致谢。

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

Answer 1

ACCESS_FINE_LOCATION 和 ACCESS_COARSE_LOCATION 尝试获取位置时都需要权限 所以在 list 文件中添加这两个权限，如果你的目标是 android 6.0 及更高版本，而不是像下面的代码一样添加这个运行时权限

   String permission = android.Manifest.permission.ACCESS_FINE_LOCATION;
            if (ActivityCompat.checkSelfPermission(SearchCityClass.this, permission)
                    != PackageManager.PERMISSION_GRANTED && ActivityCompat.
                    checkSelfPermission(SearchCityClass.this, android.Manifest.permission.ACCESS_COARSE_LOCATION)
                    != PackageManager.PERMISSION_GRANTED) {
                ActivityCompat.requestPermissions(SearchCityClass.this, new String[]
                        {permission}, PERMISSION_GPS_CODE);

            }

现在处理许可结果

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,
                                       @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if (requestCode == PERMISSION_GPS_CODE) {
        if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {


            Toast.makeText(this, "location_permission_granted ", Toast.LENGTH_SHORT).show();

        } else {

            Toast.makeText(this, "location_permission_not_granted ", Toast.LENGTH_SHORT).show();
        }
    }

}
