Android 网络框架Volley JAR包生成

   Google I/O 2013上，谷歌发布了Android网络通信框架Volley，以前我都是直接使用源码编译的，那么问题来了，怎么直接打包成jar包使用呢？

不要着急，请看如下步骤:

1、下载源码

git clone https://android.googlesource.com/platform/frameworks/volley

2、编译

      gradle build 

3、编译错误解决

Ran lint on variant release: 2 issues found
Ran lint on variant debug: 2 issues found
Wrote HTML report to file:/F:/study/opensource/volley/build/outputs/lint-results.html
Wrote XML report to F:\study\opensource\volley\build\outputs\lint-results.xml
:lint FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':lint'.
> Lint found errors in the project; aborting build.

Fix the issues identified by lint, or add the following to your build script to proceed with errors:
...
android {
    lintOptions {
        abortOnError false
    }
}

    解决方法: 在AndroidManifest.xml中添加权限

<uses-permission android:name="android.permission.USE_CREDENTIALS" />

4、获取volley.jar

      在如下目录找到class.jar改成volley.jar
      F:\study\opensource\volley\build\intermediates\bundles\release/class.jar 

    解决方法: 在AndroidManifest.xml中添加权限

<uses-permission android:name="android.permission.USE_CREDENTIALS" />
