This is the case: I use an iMac on the Intranet and access the Internet through the proxy server. In other words, this machine is newly purchased and requires the development environment to be installed. After you download and install eclipse and ADT (Android development tool

Project needs to implement two-way SSL verification on Android. Prepare the environment: Windows 2003 EE; OpenSSL; Tomcat 7; Simple process: 1. Use OpenSSL and keytools for Ca, client, and server certificates and private keys. 2. Build a Tomcat web server with two-way authentication. 3. verify the validity of two-way SSL verification with IE. For the above three steps, see the following document: https SS

First, the error is reported because the third-party classes are not found. Solution: Right-click the project Properties -------> Build Path -------> Order And Export to check the third-party jar package. Then Clear your project and re-compile and run it to solve the above problem. For details, see the above steps and then Clear the project and compile and run it. By the way, I posted the source code of Sina OAuth

first, the Knowledge reviewAbout the signature check in Android is a very common security strategy, many applications have done this part of the work, before I also introduced a few about how to use the application of the signature verification issue of the article, do not know the students can go to see: Android Blasting Application signature Verification function, At that time after the introduction of th

Oauth is required when developing Android clients such as Sina Weibo, Netease, and Sohu Weibo, that is, to open a third-party authentication webpage for authorization. After authorization, the user will jump back to the response and use up the authorization. A callback address is provided when a user is requested for authorization. After the user completes the authorization operation, it will jump back to
