It has been several months since I arrived at the Software Park. Some of the previous. Net-related things have been slowly lost. I am always concerned about related things. Some of the items subscribed in the past are still very useful. I collected some relevant information and learned some related training information. It is gratifying that many of the training courses are on the Software Park side. If you

A status code of 200 indicates a successful connection.Convert a byte stream to a stringThe inputstream reads the byte data. Once the InputStream object is acquired, it is often necessary to decode it or convert it into other types of data. For example, if you download a picture, the byte stream code should be a picture:nul

The datum points are hard to get right, so caliper does the hard work, even when you're not measuring where you want to measure it. We strongly recommend that you use

checking reference types by Getobjectreftype
Prior to Android 4.0, Getobjectreftype was not implemented correctly due to the use of direct pointers. We find through weak global tables, parameters, local tables, and global tables. First it will find your direct pointer and return the type of reference it checks. This means that if you function Getobjectreftype on a global jclass, and this jclass is passed to a static local
using animations on Textureview, some special transition types may not produce the desired effect.
Classes that inherit from Adapterview, such as the ListView, manage sub-view in a way that is incompatible with the transition framework. If the view action is animated on top of Adapterview, the device interface may be suspended.
If you want the resize animation to work on TextView, the text on the TextView is drawn to a new position before the animation is complete. To avoid this problem
