What is your CPU and RAM usage during startup? Do you have a lot of IO swapping occurring? Considering that Windows needs at least 512 to run right half of the time and Eclipse is a memory hog you probably just need more RAM.

blocks|key|2960622|text|我经历过同样的事情，在我的例子中，当在Eclipse中创建项目时，我必须设置"Min+SDK+Version“。如果没有这个设置，模拟器就不会启动。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2960623|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I've experienced the same thing and in my case I had to set "Min SDK Version" when creating the project in Eclipse. Without this setting the emulator didn't start.

blocks|key|2960640|text|仿真器通常非常慢，仿真器上的操作系统版本越高，它就越慢。我是一个游戏开发人员，用我的AMD+Athlon+X3+2.90+GHz和4+4GB内存，它给我5-6fps。我试图在Honeycomb模拟器上打开我的一个应用程序，它真的很糟糕。它打开了，但我不能用它做任何事。所以最好的答案就是买一台真正的设备。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2960641|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Emulator is in general very slow, and the higher the OS version on the emulator, the slower it gets. I'm a game developer, and with my AMD Athlon X3 2.90 GHz with 4GB RAM it gives me 5-6 fps. I tried to open one of my apps on Honeycomb emulator, and it was really terrible. It opened, but I couldn't do anything with it. So the best answer is purchasing a real device.

blocks|key|268992|text|在初始启动时，构建仿真器的时间最多不超过5-10分钟。SD卡大小对内存使用没有影响，它不会加载到内存中，它只是为SD卡创建了一个更大的图像文件。将模拟器设置为具有256mb的ram会有所帮助，但通常当我遇到同样的问题时，我只需关闭模拟器窗口并重新启动它。有时它只是在创建时挂起，而不是内存问题(我有16+to的内存，但仍然时不时地有问题)|type|unstyled|depth|inlineStyleRanges|entityRanges|data|268993|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

It shouldn't take more than 5-10min at most to build the emulator on initial startup. The SD card size has no effect on memory usage, it's not loaded into memory, it just creates a larger image file for the sdcard. Setting the emulator to have 256mb of ram will help, but in general when I have the same problem I just close down the emulator window and re-start it. Sometimes it just gets hung-up on creation and isn't a memory issue (I have 16gb of ram and still have the problem from time to time)

The native Android emulator is really slow. It's much faster if you use Android on a virtual machine. You can follow my detailed guide on setting it up. <a href="http://www.bobbychanblog.com/2011/07/faster-android-emulator-alternative-using-virtualbox/" rel="nofollow">http://www.bobbychanblog.com/2011/07/faster-android-emulator-alternative-using-virtualbox/</a>

Android Development Tools (ADT) 9.0.0 (or later) has a feature that allows you to save state of the AVD (emulator), and you can start your emulator instantly. You have to enable this feature while creating a new AVD or you can just create it later by editing the AVD.

Also I have increased the Device RAM Size to 1024 which results in a very fast emulator.

Refer the given below screenshots for more information.

My laptop: Intel Core 2 Duo CPU, 2GHz, 1GB RAM.

I created a target with SD Card 512MB, Device RAM size 512, snapshot enabled. I waited for 30 minutes but the emulator doesn't ends up loading. It keeps showing a flash word "Android" on the black screen.

Before running the emulator, I closed most other programs.

What's wrong with it? This is very frustrating. :(

Android emulator is very very slow

游戏开发

虚拟机

Android

Windows

Eclipse

我的笔记本电脑:英特尔酷睿2双核CPU，2 2GHz，1 1GB内存。我使用512MB的SD卡创建了一个目标，设备RAM大小为512，启用了快照。我等了30分钟，但是模拟器没有加载。它一直在黑屏上显示一个闪光的单词"Android“。在运行模拟器之前，我关闭了大多数其他程序。它有什么问题？这非常令人沮丧。:(
