I have a problem when I tried to start my AVD in android studio. It was working fine but all of a sudden it just turns black. I have tried to restart my pc but it didnt help. Any solution? Or is there any AVD application that I can use because android studio's AVD is kinda slow.
This also happens to me from time to time. To fix this, open your AVD Manager. Then, click the arrow to the far right. Finally, click Cold Boot Now.
I will say it will be better if you use physical mobile devices and the step to use that is mentioned below:
Pre-requesting:
Android Studio
USB cable
Android Device
Steps:
Enable USB
debugging(Link)
Automatically get device driver install on the system.
Run your app using a connected device. check ou this link
Why I am suggesting to you because this will improve your productivity of coding.
If you want multiple device testing then only go through Virtual emulator such as BlueStack, GenyMotion, AndY which I used and prefer more due to of less memory uses.
You can try Genymotion instead. It is faster than android studio's AVD and easy to use. Also in some cases, you might have riot vanguard (riot games anti cheat system), and you need to uninstall it to use android studio's AVD.
I have a mid 2013 Macbook Air (so I should have the resources to make the emulator work) and I'm trying to get the Android Emulator working. It's been half an hour and the color pinwheel continues to spin. In the meantime I looked up and downloaded Andy and BlueStacks Android emulators but Andy was nothing more than a clock with no buttons and BlueStacks, while it had a number of options there was nothing that seemed evident that I could get 'Hello World' running from the basic tutorial.

I want to progress but I'm stuck. Thanks.
I would look into Genymotion. They have a great android emulator that can spin up vms for different phones. Its free for personal use and easy to use. The VM image is download directly from their server so when it gets corrupted you can delete it and add it again.
It is also recognized by Eclipse and Android Studio.
There should be two downloads, one that includes Oracle VM and one that doesn't. I recommend the one that does so you do not need to install Oracle VM by its self.
If that doesn't work post a comment and ill see what I can do.
try restarting your computer..
When you start an emulator you should "Store a snapshot for faster performance" in the Android Virtual Device (AVD) configuration or the emulator won't start at all. After too much time troubleshooting, it was as simple as that.
i have created a AVD,it starts normally asking for "Connect to charger" and then it stops working.Unable to understand the problem.please help
You need to set a sufficient memory for your emulator in the AVD settings, try to update if you didn't and as suggested use genymotion which is a good alternative, if your using eclipse try out Android studio
I have installed the latest Version of Android Studio. Now I like to set up an Emulator. I had used the SDK Manager to load the Intel Atom Image, and set up an AVD.
I think I have done this like in all other Examples but if I start the Emulator, all what I can se is an empty home screen without any other icons or setting. I thought the emulator would be like an real device, or quite close to it.
Maybe I think wrong?
But I had seen videos where the emulator is like an real phone.
What can i do to get my emulator to an pretty phone? :)
Thanks all.
Check if in your emulator parameters the "hardware buttons" are checked. However, sometimes android studio emulators are giving some errors. You can try download Genymotion emulators for android, if you don't lack ram it will work out pretty well for you.
I have a celeron processor :/ and android emulator on eclipse uses 100% of cpu and hangs everything unless I kill it . I was just trying a hello android program from a book and don`t know much about android or even eclipse .I have the android-eclipseplugin installled .
Can someone help me with is ?thanks!
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 -noaudio flag, or by editing the AVD's config file and setting the following parameters:
hw.audioInput=no
hw.audioOutput=no
On Linux, I found that file at ~/.android/avd/myAVD.avd/config.ini
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.
For me, it was unchecking the Multi-Core CPU check box
Niels' answer worked well for me https://stackoverflow.com/a/7706018
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).
I had same issue on my macOS High Sierra and for me helps to create new AVD device and choose CPU/ABI = x86_64, not x86 in Android version dialog. Hope that helps.
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 -no-boot-anim to the emulator start-up command. Other emulator options are described here. 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.
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 http://www.genymotion.com/
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:
sudo ln -s /usr/lib/x86_64-linux-gnu/libpulse.so.0 /usr/lib/x86_64-linux-gnu/libpulse.so
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 libpulse-dev package). Then it will fall back to ALSA, which constantly calls poll, causing 100% CPU usage.
A fix for the emulator is coming, but for now, adding the symlink solves the issue.
I strongly recommend not to use android emulator. Use VirtualBox + android x86 OS (you can download it here ), 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.
