I'm running a small android project on eclipse ADT bundle. When I debug it on my SGS1 phone it works fine. However, when trying to debug it on a new SGS3 device, the device is not shown on the targets devices and I can't debug it. I've already enabled USB debugging on the device, And installed Keis and the device driver (for windows 7, 64 bit), And restarted the computer. Funny thing is, when I run the debugger in eclipse, it does run the application on the phone, it just doesn't recognize it (and of course debug breakpoints are useless in this mode). Would appreicate any help- thanks. ozbek

I downloaded the latest adt bundle (adt-bundle-windows-x86_64-20140624), and uncompresed that zip file, but when i try to open that adt, it open as juno eclipse. can any body help me to resolve this prblem. thanks in advance ADT Bundle contains Eclipse, to start Android development you need the ADT and the bundle comes with both you don't have to spend time searching for the ADT and Eclipse Marco L Same problem here, using OSX. The downloaded ADB dows not show the typical ADB buttons and other extension provided by the plugins, but just a plain Eclipse. Installing an older version of ADT (adt

1）ADT定义：是指一个数学模型以及定义在该模型上的一组操作。包括：数据对象、数据关系、基本操作。 2）ADT表示：就是要将该类型映射到计算机中，确定存储结构以及该存储结构之上基本操作的函数原型。 3）ADT实现：基于特定存储结构之上的基本操作的实现。 4）ADT小结：自定义的数据类型、定义一组数据和施与这些数据之上的一组操作，并在模块内部给出它们的表示和实现细节，在模块外部使用的只是抽象的数据和抽象的操作。（对比封装性） 5）例子 来源： https://blog.csdn.net/weixin_43237362/article/details/102728994

问题： 如何将social_kol_tmp表 中的字段cost_YA中日期为201901-201909中的值替换为相同brand和pltform对应18年月份的col_cost字段的数据,其他日期的cost_Y值不变？ 假设： social_kol_tmp表 A，social_kol_tmp表B 难点： 可以利用join on brand和pltform相等，但是日期如何匹配呢？ 思路： 通过对18年各月和对应19年的各个月份产生相应的字段，rn1和rn2 注意，理论上结果中同一行两个时间只相差一年 方案一：窗口函数生成rn1和rn2（结果需要看数据情况，原因如下） 1. 代码如下： select a.brand,a.platform,a.period as Adt,b.period as Bdt,a.col_cost,b.col_cost as cost_YNew from (select col_cost,brand,platform,period, dense_rank() over (partition by brand,platform order by period) as rn1 from social_kol_tmp where period>='201901' and period<'201909' ) a join ( select col_cost,brand

Good morning ppl. I have what it looks like to be a commong problem in android, import jars from libraries. I'm trying to use a library to consume an in house api. I copied the jar into the libs folder on my android project and went to Properties -> Java Build Path -> Libraries and added the jar. Also, I checked the boxes within the jar name in the Order and Export tab. all I have is the java.lang.NoClassDefFoundError exception . I have read almost every post that points to the same answer. Put the jar on libs folder and make the steps listed above. Nothing worked. I'm running the ADT v 20, on

I'm a .NET developer but I like JAVA so in my free time I play around with that. I don't normally use Eclipse but I installed the ADT eclipse plugin and Andriod SDK and I started learning and I made a new project with a TableLayout and it kinda looks good, and it runs ok on the emulator. However... there a few things that drive me absolutely catatonic and perhaps I am doing something wrong so please help me out. Firstly, if I change the main.xml file in whatever way, even by adding what is supposedly a correct parameter, it will start freaking out and will generate an error that just says
