The Android emulator is emulating an ARM CPU without hardware acceleration which can be pretty slow even on a core2duo for example.

You can try to reduce the screen resolution of the virtual device which should result in a small performance increase.

The emulator is notoriously slow to start; it can take 15 minutes or longer on an underpowered machine. You can speed start-up a bit by passing the <code>-no-boot-anim</code> to the emulator start-up command. Other emulator options are described <a href="http://developer.android.com/guide/developing/tools/emulator.html" rel="nofollow">here</a>. Also, some AVDs start faster than others. Try creating an AVD with the lowest level SDK that is useful for you.

Once the emulator has started, you don't need to shut it down. When an app exits (or crashes, or whatever), you can just run it again.

blocks|key|4444104|text|我强烈建议不要使用android模拟器。使用VirtualBox+%2B+android+x86+OS+(你可以从here下载)，你会得到真正的性能提升。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|4444105|不幸的是，据我所知，它不是来自谷歌，它只支持Android+2.2。我真的不明白，为什么谷歌不打算让模拟器像iPhone模拟器一样快，或者让官方的x86发布来进行调试。我不需要模拟ARM处理器指令，我认为99%25的开发人员也不需要它。|4444106|entityMap|0|LINK|mutability|MUTABLE|url|http://www.virtualbox.org/|1|http://www.android-x86.org/^0|M|A|0|1J|4|1|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@$A|Q|B|R|1|S]|$A|T|B|U|1|V]]|C|$]]|$1|D|3|E|5|6|7|W|8|@]|9|@]|C|$]]|$1|F|3|-4|5|6|7|X|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]|N|$5|I|J|K|C|$L|O]]]]

I strongly recommend not to use android emulator. Use <a href="http://www.virtualbox.org/" rel="nofollow">VirtualBox</a> + android x86 OS (you can download it <a href="http://www.android-x86.org/" rel="nofollow">here</a> ), and you will get real perfomance increase.

Unfortunately, as far as i remember, it is not from google and it supports only Android 2.2. I really do not understand, why google is not going to make simulator as fast as iPhone simulator , or to make official x86 release for debugging. I do not need emulating ARM processor instructions and I think 99% developers do no need it too.

blocks|key|4444171|text|我遇到了完全相同的问题，并找到了一个适合我的解决方案。在AVD的配置中，我已经设置了一个额外的标志“音频播放支持”为"no“。我还确保了AVD有1+1GB的RAM。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4444172|这对我很有效。|4444173|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

I've had the exact same problem and found a solution that works for me.
In the config of the AVD I've set an extra flag "Audio playback support" to "no".
I've also made sure the AVD has 1GB of RAM.

This worked for me.

blocks|key|5860391|text|Niels的回答对我https://stackoverflow.com/a/7706018很有效，因为模拟器停止使用100%25的CPU+(下降到10-15%25)，而且它还有另一个有用的“副作用”。我注意到，当模拟器运行时，在Totem中播放视频或在RhythmBox中播放音乐会阻塞。VLC将播放视频，但拒绝播放视频的配乐。一旦模拟器被关闭，音乐就会开始播放。Niels将"Audio+playback+support“设置为"no”的答案可防止此问题。我正在运行Ubuntu11.04和Android模拟器版本13.0+(build_id+OPENMASTER-172639)。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|5860392|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/a/7706018^0|A|Z|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

Niels' answer worked well for me <a href="https://stackoverflow.com/a/7706018">https://stackoverflow.com/a/7706018</a>
in that the emulator stopped using 100% CPU (dropped down to 10-15%)
Furthermore it had another useful "side effect". I noticed that playing video in Totem or music in RhythmBox would block while the emulator was running. VLC would play video but refuse to play the accompanying soundtrack for the video.
As soon as the emulator was killed, music would start playing.
Niels' answer to set "Audio playback support" to "no" prevents this issue.
I am running Ubuntu 11.04 and Android emulator version 13.0 (build_id OPENMASTER-172639).

blocks|key|2331620|text|值得一提的是Genymotion。这是一个基于VirtualBox的安卓模拟器，带有预先创建的图像。它支持一些常用的Android模拟器不太擅长的功能，比如Wifi3G、蓝牙、GPS+(与Google+Maps集成在一起，所以你不必手动查找坐标)，多屏幕等。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2331621|值得在http://www.genymotion.com/上试一试|offset|length|2331622|entityMap|0|LINK|mutability|MUTABLE|url|http://www.genymotion.com/^0|0|3|Q|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@$D|P|E|Q|1|R]]|A|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]]]

One alternative that worths mentioning is Genymotion. It's an android emulator based on VirtualBox, with pre-created images. It supports some features the stock Android emulator isn't very good at, like Wifi 3G, Bluetooth, GPS (with a fancy Google Maps integration, so you don't have to find coordinates manually), multiple screens, etc.

It worth giving it a try at <a href="http://www.genymotion.com/" rel="nofollow">http://www.genymotion.com/</a>

blocks|key|2331646|text|正如其他人所说，解决方案是禁用声音。不幸的是，在最近的Android+Studio版本中(我使用的是1.4)，禁用声音的选项已经从GUI中删除。要禁用声音，您可以通过使用AVD标志从命令行启动仿真器，或者编辑-noaudio的配置文件并设置以下参数：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2331647|hw.audioInput=no
hw.audioOutput=no|code-block|syntax|javascript|2331648|在Linux上，我在~/.android/avd/myAVD.avd/config.ini找到了这个文件。|2331649|entityMap^0|2W|8|0|0|A|Z|0^^$0|@$1|2|3|4|5|6|7|O|8|@$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|R|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|S|8|@$9|T|A|U|B|C]]|D|@]|E|$]]|$1|M|3|-4|5|6|7|V|8|@]|D|@]|E|$]]]|N|$]]

As others have said, the solution is disabling sound. Unfortunately, in recent Android Studio releases (I'm using 1.4) the option to disable sound has been removed from the GUI. To disable sound you can do it either by launching the emulator from the command line with the <code>-noaudio</code> flag, or by editing the AVD's config file and setting the following parameters:

<pre><code>hw.audioInput=no
hw.audioOutput=no
</code></pre>

On Linux, I found that file at <code>~/.android/avd/myAVD.avd/config.ini</code>

blocks|key|5860466|text|我在Ubuntu+14.04上运行模拟器时遇到了这个问题。禁用音频确实会降低CPU使用率，但如果您需要音频工作，可以通过添加符号链接进行修复：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5860467|sudo+ln+-s+/usr/lib/x86_64-linux-gnu/libpulse.so.0+/usr/lib/x86_64-linux-gnu/libpulse.so|code-block|syntax|javascript|5860468|原因是仿真器尝试使用pulseaudio作为后端，但将无法链接到Ubuntu上不存在的libpulse.so+(除非您安装了libpulse-dev包)。然后，它将回退到ALSA，它不断调用轮询，导致100%25的CPU使用率。|offset|length|style|CODE|5860469|一个fix+for+the+emulator+is+coming，但是现在，添加符号链接可以解决这个问题。|5860470|entityMap|0|LINK|mutability|MUTABLE|url|https://android-review.googlesource.com/#/c/200749/^0|0|0|1Q|C|0|2|U|0|0^^$0|@$1|2|3|4|5|6|7|W|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|X|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Y|8|@$I|Z|J|10|K|L]]|9|@]|A|$]]|$1|M|3|N|5|6|7|11|8|@]|9|@$I|12|J|13|1|14]]|A|$]]|$1|O|3|-4|5|6|7|15|8|@]|9|@]|A|$]]]|P|$Q|$5|R|S|T|A|$U|V]]]]

I had this issue running the emulator on Ubuntu 14.04. Disabling the audio does bring down the CPU usage, but in case you need audio to work, it can be fixed by adding a symlink:

<pre><code>sudo ln -s /usr/lib/x86_64-linux-gnu/libpulse.so.0 /usr/lib/x86_64-linux-gnu/libpulse.so
</code></pre>

The reason for this is that the emulator tries to use pulseaudio as the backend, but will be unable to link to libpulse.so, which does not exist on Ubuntu (unless you installed the <code>libpulse-dev</code> package). Then it will fall back to ALSA, which constantly calls poll, causing 100% CPU usage.

A <a href="https://android-review.googlesource.com/#/c/200749/" rel="nofollow">fix for the emulator is coming</a>, but for now, adding the symlink solves the issue.
