Android插件 PubNub utilizes a Publish/Subscribe model for real-time data streaming and device signaling which lets you establish and maintain persistent socket connections to any device and push data to global audiences in less than ¼ of a second. The atomic components that make up a data stream are API Keys, Messages, and Channels.(PubNub Java-based SDKs for Java/Android PubNub utilizes a Publish/Subscribe model for real-time data streaming and device signaling which lets you establish and maintain persistent socket connections to any device and push data to global audiences in less than ¼ of a second.

【实例简介】

设计的Android自定义View，模仿老电话式旋转拨号盘，按住数字键后绕着圆心进行旋转，当旋转到第三象限时，中心图片会改变，在第三象限抬起手，就会将按住的数字填入编辑框，也可点击编辑框后的后退按钮进行撤销操作，编辑完后点击中心图片会验证所填入密码是否正确。我当前设计的密码是123.(Design custom Android View, imitating the old rotary dial phone, hold the number key to rotate around the center of the circle, when the rotation to the third quadrant, the center picture will change, raised his hand in the third quadrant, they will be Press and hold the digital fill edit box can also click the Back button in the edit box for withdrawal after the operation, after editing click on the picture will validate the populated center of the password is correct. My current design code is 123.)
