Android-maven配置multidex打包

转自：http://blog.csdn.net/goldenfish1919/article/details/42006649

工程大了以后，不可避免就会出现方法数目超出65536的限制，很幸运的是新的android提供了多dex打包的方式可以解决这个问题。下面我们就来看下如何用android-maven-plugin打多dex包。

先看下工程结构：

并不是一个标准的maven工程，但是可以通过更改配置来完成打包。工程的代码非常简单，MainActivity有一个按钮，点击按钮跳转到SecondActivity，SecondActivity中引用了fastjson做了一个对象转string的操作，然后弹出toast提示。还有就是DemoMultiDexApplication继承了MultiDexApplication。假如你的Application已经继承了别的类，那么也可以重写attachBaseContext()来实现。

[java] view plain copy

 

1. public class DemoMultiDexApplication extends MultiDexApplication {  
2.     /*如果已经继承了别的类，可以重写下面的方法 
3.     @Override 
4.     protected void attachBaseContext(Context base) { 
5.         super.attachBaseContext(base); 
6.         MultiDex.install(this); 
7.     } 
8.     */  
9. }  

重点看一下pom：

签名的时候就是使用的默认的keystore来签名的。

所使用的maven环境：

以上就是所有要做的了。

另外就是maven打好的包很可能启动不起来，可以用adb logcat来抓取logcat的日志。
