问题描述

崩溃在这里......

android.database.sqlite.SQLiteException：在“ GROUP”附近：语法错误（Sqlite代码1 SQLITE_ERROR）：，在编译时：从图像中选择_id，bucket_display_name，bucket_id，_id，方向（（is_pending = 0）AND（ is_trashed = 0）AND（volume_name IN（'external_primary'）））AND（（（1）GROUP BY 1，（2））ORDER BY date_modified DESC，（OS错误-2：无此文件或目录） 在android.database.DatabaseUtils.readExceptionFromParcel（DatabaseUtils.java:184） 在android.database.DatabaseUtils.readExceptionFromParcel（DatabaseUtils.java:140） 在android.content.ContentProviderProxy.query（ContentProviderNative.java:423） 在android.content.ContentResolver.query（ContentResolver.java:955） 在android.content.ContentResolver.query（ContentResolver.java:891） 在android.content.ContentResolver.query（ContentResolver.java:840）

下面是显示所有文件夹或图像相册的方法。

private boolean logGalleryFolders() {

        }
        cur.close();
        return true;
    }

下面是崩溃线……

Cursor cur = this.context.getContentResolver().query(Media.EXTERNAL_CONTENT_URI,"date_modified DESC");

解决方法

只需像下面这样更改查询：

来自

 Cursor cur = this.context.getContentResolver().query(Media.EXTERNAL_CONTENT_URI,new String[]{"_id","bucket_display_name","bucket_id","_id","orientation"},"1) GROUP BY 1,(2",null,"date_modified DESC");

到

Cursor cur = this.context.getContentResolver().query(Media.EXTERNAL_CONTENT_URI,"date_modified DESC");

,

您的GROUP BY位于And的内部，从而引起了问题。请如下更改您的query：

SELECT
  _id,bucket_display_name,bucket_id,_id,orientation
FROM
  images
WHERE
  (
    (is_pending = 0)
    AND (is_trashed = 0)
    AND (volume_name IN ('external_primary'))
  )
  AND ((1))
GROUP BY
  1,(2)
ORDER BY
  date_modified DESC
