Android 调用系统相机以及相本源码

Android 调用系统相机拍照、以及相册。完成之后图片是上传到app上。前面的功能已经测试过了。没有上传到服务器，因为我没服务器测试。但项目里面有个类可以参考上传图片到服务器，我就没测试了。接下来看代码，虽然注释写得少，但其作用看英文单词意思，又在或是查看调用。

NetUtil这个类，我也是参考网上的，没测试过。是图片上传服务器的。

记得加入权限，权限主要是访问sd存储，以及调用系统相机，相册。上传服务器权限也有了。只是我没服务器测试。

    <uses-permission android:name="android.permission.CAMERA" />    <uses-permission android:name="android.permission.INTERNET" />    <uses-permission android:name="android.permission.VIBRATE" />    <uses-permission android:name="android.permission.INTERNET" />    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
