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：

Android-maven配置multidex打包

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 plaincopy
Android-maven配置multidex打包Android-maven配置multidex打包
  1. publicclassDemoMultiDexApplicationextendsMultiDexApplication{
  2. /*如果已经继承了别的类，可以重写下面的方法
  3. @Override
  4. protectedvoidattachBaseContext(Contextbase){
  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：

Android-maven配置multidex打包

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。
