android - ContentProviderClient release() 弃用

Question

我找到了一些删除数据库并使用 ContentProvider 重新创建它的解决方案。

        ContentResolver resolver = mContext.getContentResolver();
        ContentProviderClient client = resolver.acquireContentProviderClient(KOOPSContentProvider.AUTHORITY);

        assert client != null;
        KOOPSContentProvider provider = (KOOPSContentProvider) client.getLocalContentProvider();

        assert provider != null;
        provider.resetDatabase();

        client.release();

但是在 ContentProviderClient 类中有 release() 是deprecated，有没有其他方法可以释放资源。

编辑:如果我尝试使用 close()，它会显示如下警告。

This ContentProviderClient should be freed up after use with #release().

Many resources, such as TypedArrays, VelocityTrackers, etc., should be recycled (with a recycle() call) after use. This lint check looks for missing recycle() calls.

和close()显示为禁用，为什么？

如果有人想知道代码应该是什么:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N)
{
    client.close();            
}
else
{
    client.release();
}
