折腾：
【已解决】Android ADT中增大AVD内存后无法启动：emulator failed to allocate memory 8
过程中，增大对应AVD的内存为2G后，结果无法启动AVD了：

【解决过程】
1.所以，重新改小为1G试试：
结果问题依旧。
2.参考：
Android Emulator: Failed to allocate memory: 8 even with 8MB RAM
说是，只能是256/512/1024
但是很明显，我上面改成1024也是不行的。
参考最后一个人的解释，去改为900MB，看到log为：

然后再去试试，结果错误依旧。
3.改回之前配置的512MB，是可以的。
但是不是我想要的，想要的就是，尽量让内存大点，以此希望能让AVD模拟器跑的快点，不要这么慢。
4.再去改为768MB，结果又显示和之前的snapshot不一致，所以还不给启动：

5.所以，先去把snapshot去掉，然后再启动，启动后，关闭掉，再次勾选上snapshot。
结果还是同样提示：
ERROR: Unable to load VM from snapshot. The snapshot has been saved for a different hardware configuration
所以，估计只能是删除掉，重新建一个，也许才可以的。
6.重新新建一个AVD：
然后用这个AVD试试效果。
然后是可以启动的。
不过速度也还是很慢。
6.继续参考该贴，先去设置为1024MB，
然后再去把：
C:UsersCLi.androidavdSamsungGalaxySII.avdconfig.ini
中的：
hw.ramSize=1024
改为
hw.ramSize=1024MB
然后去运行试试，结果出现：
Emulator] emulator: ERROR: Unable to load VM from snapshot. The snapshot has been saved for a different hardware configuration.
再去取消掉snapshot，再运行，的确是可以运行的。
【总结】
结论是：
当前有个bug：
默认是通过
hw.ramSize=1024
来判断内存大小的，但是当是>=1024时，就无法正确识别了。
必须手动把对应的
C:UsersCLi.androidavdSamsungGalaxySII.avdconfig.ini
中的
hw.ramSize=1024
改为
hw.ramSize=1024MB
就可以了。
提示：
1. 手动改了后，结果会导致界面中无法正确显示：
总之，还是很悲催，bug还是很大的说。
2.虽然改为1024MB，甚至2048MB，但是实际上运行AVD的时候，貌似还是原始的（我所选的那个设备Nexus的）343MB：
总之，更加坑爹。。。
