长期维护的Android项目，里面包括常用功能实现，以及知识点详解，

当然还有Java中的知识点。具体请看github：

说明，本人从github上下了一个代码，导入到AndroidStudio中，编译没问题，不过突然运行的时候就报错了。提示没有jdk8,大概意思我理解的就是这样。因为我电脑上一直都是装JDK7的，所以就google搜了一下答案，然后就解决了。下面是错误代码：

Error:FAILURE: Build completed with 2 failures.

1: Task failed with an exception.
-----------
* What went wrong:
Execution failed for task ':app:compileDebugJavaWithJavac'.
> When running gradle with java 5, 6 or 7, you must set the path to jdk8, either with property retrolambda.jdk or environment variable JAVA8_HOME

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
==============================================================================

2: Task failed with an exception.
-----------
* What went wrong:
A problem was found with the configuration of task ':app:compileRetrolambdaDebug'.
> Directory 'D:\AndroidStudio\AndroidSamples\app\build\retrolambda\debug' specified for property 'inputDir' does not exist.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
==============================================================================

解决方法：1，去安装jdk7,然后配置好环境变量。

2，修改AndroidSutdio本地的jdk目录。

AndroidStudio->Project Structure->更改JDK location改为JDK8即可。
