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：

[2012-12-18 18:01:38 - Emulator] Failed to allocate memory: 8 
[2012-12-18 18:01:38 - Emulator] 
[2012-12-18 18:01:38 - Emulator] This application has requested the Runtime to terminate it in an unusual way. 
[2012-12-18 18:01:38 - Emulator] Please contact the application’s support team for more information.

 

【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：

[2012-12-18 18:16:04 - SDK Manager] Snapshot image already present, was not changed. 
[2012-12-18 18:16:04 - SDK Manager] SD Card already present with same size, was not changed.

[2012-12-18 18:16:04 - SDK Manager] hw.ramSize=900

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：

[2012-12-18 18:19:00 - DownloadSongtasteMusic] —————————— 
[2012-12-18 18:19:00 - DownloadSongtasteMusic] Android Launch!

[2012-12-18 18:19:00 - Emulator] emulator: ERROR: Unable to load VM from snapshot. The snapshot has been saved for a different hardware configuration.

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:\Users\CLi\.android\avd\SamsungGalaxySII.avd\config.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:\Users\CLi\.android\avd\SamsungGalaxySII.avd\config.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。。。
