so库冲突问题解决

在开发高德地图的时候出现如下错误

根据错误提示，找不到so库里面的方法。由于之前的地图一直在使用，so库放在armeabi下面，地图加载没有任何问题.

问题排除

经过一系列的问题排除，最终确定是由于armeabi-v7a库的问题，由于其他moudule下面存在armeabi-v7a库，所以高德sdk去其他moudule下面去找相应的方法就会报

java.lang.UnsatisfiedLinkError: Native method not found: com.autonavi.amap.mapcore.MapCore.nativeNewInstance:(Ljava/lang/String;Ljava/lang/String;)J

经过了解资料

所以armeabi-v7a 应该是与AIR限定支持android2.2以上的条件有关。android2.2以上能让硬件发挥更大的作用。

对于AIR项目来说性能问题是最大的瓶颈，能优化一点就一点，所以如果接平台方SDK或者写ANE的时候使用到SO库，个人推荐全部放到armeabi-v7a下，而不要为了兼容放到armeabi。
armeabi-v7a库对系统进行了优化，所以会去armeabi-v7a文件下面调用

解决方案

把armeabi文件下面的库文件copy到armeabi-v7a，完美解决找不到so库的问题
