Android Sdk升级问题(虽然有点慢,但起码可靠)

本文指导如何通过AndroidSDKManager配置代理服务器,解决国内访问Google服务器的网络问题。
解决国内访问Google服务器的困难: 
1).启动 Android SDK Manager ; 
2).打开主界面,依次选择「Tools」、「Options...」,弹出『Android SDK Manager - Settings』窗口; 
3).在『Android SDK Manager - Settings』窗口中,在「HTTP Proxy Server」和「HTTP Proxy Port」输入框内填入mirrors.neusoft.edu.cn和80,并且选中「Force https://... sources to be fetched using http://...」复选框;4.设置完成后单击「Close」按钮关闭『Android SDK Manager - Settings』窗口返回到主界面; 
5).依次选择「Packages」、「Reload」。
The TPS54331 is a 28-V, 3-A non-synchronous buck Integrated 80 mΩ High Side MOSFET Supports up to 3A Continuous Output Current converter that integrates a low Rds(on) high side MOSFET. To increase efficiency at light loads, a pulse skipping Eco-mode™ feature is automatically High Efficiency at Light Loads with a Pulse activated. Furthermore, the 1 A shutdown supply Skipping Eco-mode™ current allows the device to be used in battery Fixed 570kHz Switching Frequency Typical 1A Shutdown Quiescent Current powered applications. Current mode control with internal slope compensation simplifies the external compensation calculations and reduces component Adjustable Slow Start Limits Inrush Currents count while allowing the use of ceramic output Programmable UVLO Threshold Overvoltage Transient Protection capacitors.
