1.2、Glide

Glide 是一个 Android 上的图片加载和缓存库，其目的是实现平滑的图片列表滚动效果

https://github.com/bumptech/glide

http://www.oschina.net/p/glide

// For a simple view:
@Override
public void onCreate(Bundle savedInstanceState) {
...

ImageView imageView = (ImageView) findViewById(R.id.my_image_view);

Glide.with(this).load("http://goo.gl/h8qOq7").into(imageView);
}

// For a list:
@Override
public View getView(int position, View recycled, ViewGroup container) {
final ImageView myImageView;
if (recycled == null) {
myImageView = (ImageView) inflater.inflate(R.layout.my_image_view,
container, false);
} else {
myImageView = (ImageView) recycled;
}

String url = myUrls.get(position);

Glide.with(myFragment)
.load(url)
.centerCrop()
.placeholder(R.drawable.loading_spinner)
.crossFade()
.into(myImageView);

return myImageView;
}

1.3、Android-Universal-Image-Loader

Android library #1 on GitHub. UIL aims to provide a powerful, flexible and highly customizable instrument for image loading, caching and displaying. It provides a lot of configuration options and good control over the image loading and caching process.

1.4、Fresco

Fresco is a powerful system for displaying images in Android applications.
Fresco takes care of image loading and display, so you don't have to. It will load images from the network, local storage, or local resources, and display a placeholder until the image has arrived. It has two levels of cache; one in memory and another in internal storage.
In Android 4.x and lower, Fresco puts images in a special region of Android memory. This lets your application run faster - and suffer the dreaded OutOfMemoryError much less often.
Fresco also supports:
streaming of progressive JPEGs
display of animated GIFs and WebPs
extensive customization of image loading and display and much more!

3.2、xUtils

xUtils 包含了很多实用的android工具。
xUtils 最初源于Afinal框架，进行了大量重构，使得xUtils支持大文件上传，更全面的http请求协议支持(10种谓词)，拥有更加灵活的ORM，更多的事件注解支持且不受混淆影响...
xUitls最低兼容android 2.2 (api level 8)

5、开源工具

5.1、ButterKnife

Field and method binding for Android views。通过注解的方式实现View以及事件绑定
https://github.com/JakeWharton/butterknife
Android ButterKnife Zelezny 插件可以有效的提高生产效率（Android Property Initializer）
https://github.com/avast/android-butterknife-zelezny

5.2、Parceler

Parceler is a code generation library that generates the Android Parcelable boilerplate source code. No longer do you have to implement the Parcelable interface, the writeToParcel() or createFromParcel() or the public static final CREATOR. You simply annotate a POJO with @Parcel and Parceler does the rest. Because Parceler uses the Java JSR-269 Annotation Processor, there is no need to run a tool manually to generate the Parcelable code. Just annotate your Java Bean, compile and you are finished.
