Can anyone tell me how to update the database in android. I created an app with an embedded database. I changed the version of the database in the manifest and created the on update method. I wanted to test it to see if the database was updating properly but when I use the adb command only the -r will allow me to do a reinstall but it keeps the database. Is there a way to run the adb command that will allow me to update the database. Thanks.

推荐答案

下面是我会怎么处理我的updateRow方法：

Here is how I would handle my updateRow method:

public void updateRow(long rowId, String code, String name) {
      ContentValues args = new ContentValues();
      args.put("code", code);
      args.put("name", name);
      db.update(DATABASE_TABLE, args, "_id=" + rowId, null);
}
