我已经尝试了许多创建频道的解决方案，但是当它在Oreo设备中收到时我仍然没有收到通知内容。通知声音即将到来但通知抽屉中没有实际通知。
以下是我现有的代码。

private Context mContext;
private Bundle bundle;
private SharedPreferences sharedPreferences;

this.mContext = context;
this.bundle = bundle;
this.sharedPreferences = sharedPreferences;

答案 0 :(得分：6)
尝试以下简单的代码我遇到了同样的问题而且它在oreo中不起作用。以下代码肯定会起作用： -
WITH
RECURSIVE query_1
AS (
--some recursive query
)
,RECURSIVE query_2
AS (
--another recursive query based on results from query_1
)
SELECT *
FROM query_2
