不飞则已，一飞冲天；不鸣则已，一鸣惊人。这篇文章主要讲述Android6.0权限申请工具类相关的知识，希望能为你提供帮助。
android6.0以上，有部分权限是需要申请的。共9组，只要一个权限申请成功默认这一组的权限也申请成功，看下图：

activity调用：

实现activitycompat.onRequestPermissionResultCallback重写其中方法，其次在需要申请的位置调用permissionUtils.requestPermission();

1 @Override 2public void onRequestPermissionsResult(final int requestCode, @NonNull String[] permissions, 3@NonNull int[] grantResults) { 4PermissionUtils.requestPermissionsResult(this, requestCode, permissions, grantResults, mPermissionGrant); 5}
