Is there a way to make the emulator work correctly ? it is extremly slow and there is really no way to debug application this way.
Anyone experiencing this ?
Note : This is for the android 3.x platform of the SDK.
Thanks.
Everyone is experiencing this issue, even who have Intel i7 with 16 gb of ram...
The problem is that the biggest resolution (mostly 1280x800) have killed the emulator performance...
At the last google I/O some kind of hardware acceleration was shown, but it's in early stage of development I think.. But the performance were way better.
Today the only solution to develop on Honeycomb is to buy a real tablet..
The Android Emulator is slow with every OS version (but Google is working on it). Also, if you're running the Emulator on an already slow system, this slows it down, too.
If you're getting any errors, feel free to post the outputted error-messages. Otherwise I'm afraid you'll have to wait until the performance-issues are solved.

In Android Studio (version: Android Studio Dolphin 2021.3.1 Patch 1) before downloading virtual image with Android 12 (API 33, Tiramisu) I had to agree to the license agreement that start with the following worrying me statement:
To get started with the Android SDK Preview, you must agree to the
following terms and conditions. As described below, please note that
this is a preview version of the Android SDK, subject to change, that
you use at your own risk. The Android SDK Preview is not a stable
release, and may contain errors and defects that can result in serious
damage to your computer systems, devices and data.
The same for 32 API (Android 11). For Android 7 there was no such warning.
Is it safe now to install and use this emulators? What damage can happen to computer? How to prevent it? Does someone already install and use them?
In the similar question I found the following recommendations about potential overheating PC:
It could potentially damage your laptop if it overheats. But that is
why the fan is running. It is trying to cool down. If it gets too hot
your computer will start throttling programs, apps and processes to
try and cool down. And if it gets too hot it should shut itself down
to prevent damage. Make sure to keep and vents and fans clear, clean
and free for airflow.
This is the only main problem with this emulators?
Any emulator is doing something the pc isn't handled to do, this goes double for mobile apps. Worst case scenario I had with emulating a G phone was that when closing the app the pc would slowly start to crash which I would need to restart in order to get it working normally (also the lack of space on the ssd made a problem too) but no major damage was made. Of course don't neglect your pc, the more you complex stuff you try to emulate the more your pc will gasp for air, give it some breathing room now and then, take a break and keep going. If for example you are using flutter dart has a nice API that you can use online that won't effect your pc at all.
Also this goes triple for laptops since most don't have that good of a cooling.
I tried to install 33 API (Tiramisu) emulator on Notebook ThinkPad T420 (processor: i5-2520M CPU 2.50GHz, memory: 8 Gb, SSD) with enabled virtualization. Emulator boots about 8 minutes. Works terribly slow. Always reads or writes something to SSD (since memory is not enough it is using swap). Not possible to use. Temperature of CPU is near to critical level: ~90°C.
PC must have more resources otherwise there is real risk to damage it.
We have developed a react-native (v0.17.0) application for both iOS and Android. The iOS version is very responsive on physical devices. On Android devices I see a tremendous amount of variability. On Android version 5.1 the app is super responsive. On two separate phones with 5.1.1 (and both phones with much better specs) it is highly unresponsive. The navigation takes at least five seconds, TouchableHighlight buttons sometimes do not register at all. I have of course turned off dev mode but the issue still persists. My issue is that I can't see the degrade in performance on the emulator and this makes it hard to pin down the issue. Has anybody experienced and fixed a similar issue? What would be an advisable way to pinpoint the issue?
Disabling dev mode should help on android because it is super slow.
There are a little lack of details about what you are using or doing in your app. But i also had some performance issues in the app and could find the reasons for those by using the sysTrace wich is explained in the following link

Maybe you can take advantage out of this.
I'm on Windows 7 with i7 processor and I'm trying to use Android SDK Emulator. However, when I set pixel density to 320 and turn GPU emulation on it starts to lag and freeze and its browser is almost not usable (it's like 1 frame or less per second).
So far with the below settings it's much, much better and I would qualify it as 5 to 10FPS which is usable but it's not 30FPS (smooth usage).
Abstracted LCD Density - 120
GPU Emulation - NO
Keyboard Support - YES
Can anything else be done to make it work smooth except moving to Linux? I noticed that GPU emulation impacted the performance the most.
The most important setting is your architecture, make sure you are using an Intel emulator. The speedup is tremendous!
A how-to is posted here: https://stackoverflow.com/a/10772162/1741111
If you are trying to achieve that 30FPS mark, forget Android emulator and switch to Genymotion.
I was working on Android emulators for 6 or more months before i discovered Genymotion emulator and what difference that has made to the speed of development.
If you are still developing on Android emulator - go and give Genymotion a try. You will thank me for that. Its a huge difference.
There is a free version for individual developers.
Even though this is an old post. I think this needs a mention here.
You don't need to buy a phone. The emulator is a great tool, however very slow. You can enable hardware acceleration to make it run smoothly. Follow the steps on the developers page and you'll notice a remarkable difference in the speed. AFAIK the settings you mentioned do no have that great influence on the speed.
I have wrote a short blog post on speeding up the emulator and adding Google map support:
the first part will be relevant to you. try the Hardware acceleration and tell us what you think:

Speeding Up the Emulator
The best emulator is to buy a simple Android Smartphone and debug/run your apps on this device. I'm doing this and it works wonderfully with no laggs
Is there any way to get the emulator work normally ?
Its still very slow and useless, I tried adjusting the cache size and Ram.
My system configuration is quite good, are there any tips and hints to speed up the avd ?
Not much you can do, but Al Sutton lays out some things that can help a bit.

For serious development, you'll need a Honeycomb tablet.
You may have heard the many complaints about how slow the Honeycomb emulator is. And indeed, the Android emulators have long been slow. Certainly slower than most phones. But Honeycomb is slower, so much so, that even Google engineers have admitted it makes more sense to develop testing on a real tablet.
Now my experience has been a little surprising: on my 1.6(?)GHz Pentium with 4G of memory running Win7, I have been surprised at how fast it runs. That is, I was prepared for the worse, yet found the response time to taps surprisingly reasonable.
That said, it is still noticeably slower than the 2.2 emulator. But not as slow as the real hardware we had to suffer with in the 80s;)
Finally, not only the emulator, but the whole SDK (including that memory hog Eclipse) become a LOT more usable when you have at least 3.5G of memory available. This means a 4G stick. When I was trying to run the 1.6 SDK under Linux with only 2G, it was frustrating how often Eclipse locked up. But with 4G, it is fine. So upgrade your memory to at least 4G before you worry about other measures, such as faster CPU.
I'm getting started with Android development, but the emulator performance on my machine leaves much to be desired. In all fairness, my machine is not a powerhouse by any stretch of the imagination.
Short of upgrading my hardware or spending $$$, are there any good tips for improving Android emulator performance?
Is testing on your own phone an option? That is a million times faster.
Also, are you "debugging" or "running" your app? If you don't need to step through code, consider running it rather than debugging it.
If you haven't added 2.2 to your toolbox, that will help. Once it's started, emulated 2.2 runs a bunch faster than emulated 2.1.
I still go back and test my applications on the older OSes, but for day-to-day development 2.2 has helped a lot.
