将表格名称中的前导斜杠更改为URI解决了这个问题。

答案 0 :(得分：2)
Android 4.3中添加了对带有前导斜杠的路径的支持。请参阅addUri的说明，其中说明了
从API级别JELLY_BEAN_MR2开始，此方法将接受路径中的前导斜杠。
所以只需删除路径中的前导斜杠。
即。替换
abcabc通过
uriMatcher.addURI(AUTHORITY, ITEMS_TABLE,ITEMS);
顺便说一句。 uriMatcher.addURI(AUTHORITY, ItemsContract.TABLE_ITEMS);
方法中的最后一个case语句缺少query，这意味着break;将始终抛出异常。
