My app wont run on the emulator of android studio - android

emulator starts but there is no app on it besides it takes a lot of time to load. Is it because of windows?

If u have a device that runs on an Android operation system, you can run your app on that device, and it will be much faster. Andriod Studio and it's emulators require a lot of resources. So if you don't have a decent amount of RAM available for the program, it will slow down. If you still want to use the emulator,try closing applications you are not using. Like internet browsers, games, etc.. modify vitual memory pageing file size.

Run your app in Android Studio by connecting it to Actual Device or through APK

Is it better to test your application via USB (directly connecting your phone to the Android Studio) or by downloading the APK version of your app. I've been using emulator and it's really time consuming because it keeps lagging on my laptop. I wanna know which is faster and safer?
Connecting your phone via USB is always a more reliable and faster option (even if u don't consider the time it takes to copy and paste your APK file from pc to phone) You can also do a activity restart rather than restarting whole app this way which is less time consuming. You can even specify a certain activity to launch for testing. It also provides lots of Monitoring options like device monitoring, Network Monitoring, Database Inspection, Layout Inspection and so on.

My emulator is taking up too much memory

As per the title, my Android Studio seems to be using too much memory, even at idle. For my friend, he is able to run his emulator at only ~300MB of RAM usage, according to Windows' Task Manager. I've tried duplicating his emulator settings, even with his emulator set to 1.5GB of RAM, it is only using about 300MB. Mine goes up to 1.5GB, sometimes even 2GB, just by getting it started, I'm not even running any apps on it.
Is this even possible? Running it at only ~300MB, because on mine, the lowest I can go is 1024MB, setting anything lower results in no change in Task Manager.
Maybe in the installation process you installed more things than him. That's why it's eating a lot more memory

Android Emulator becomes very slow all of a sudden

I am using the Android version 4.0.3 on a Windows system. My emulator was working pretty well, however all of sudden it became very slow.
It is taking too much time in launching so most of the time launch gets cancelled or I have to start the emulator ahead of time.
If you are having long times in emulator startup, you can configure AVD to save a snapshot of emulator. This significantly improves startup time, although the shutdown time will increase due to the saving of snapshot.
If you are having a slow emulator in general (booting and running programs), and, if you are using a Intel x86 processor you can install Intel Hardware Accelerated Execution Manager from android SDK. This will improve emulator speed by more then 10 times compared to the standard emulator. It even faster then a mid range real device.
good luck.
The emulators, all of them, on every platform, are infamous for slow startups. Typically you start the emulator, wait 'til it is all the way up, and then run your program. Debugging on a real device is infinitely preferable.
Leaving the emulator open between program runs is a necessity.
One of my professors gave up and spent several thousand dollars on a new computer with a huge solid-state drive because he could not get an emulator window up in less than five minutes, and it was impacting his ability to teach courses based on the platform. I went the cheaper route and dropped $200 on a tablet. Either way, hardware is the real answer here.

Android Emulator for Tablet

My PC is core i-5 with 4gb RAM.
whenever i try to run an AVD in eclipse it comes fast, if i want to run an AVD for TAB it take 5 to 10 minutes. Is there any way to make it fast? Also some time it comes with blackscreen says open gl es API problem type something
Also after fast run, i dont close it, i use it same AVD for all run. But it becames slower after every installation or run by my app. so i have to close and restart my AVD, is there any solution for it. Also some time DDMS cant find AVD, while it was running in font.
Anyone face these problem? any tricks?
one another thing, some time app dont run automatically after installation, i have to select app in AVD's APPS
The Android emulator does not make use of multiple cores. Whether you have 1 or 8 cores doesn't matter. However, the speed of a single core does affect the speed of the emulator.
Having a processor with TurboBoost helps considerably, in my experience. Additionally, it is well known that the 3.X and above emulators are extremely slow by nature.
You could also try allocating more RAM to the AVD in it's setup. Reducing the screen size and resolution also helps in speeding up the emulator.
You can refer to this Google Group thread for details on why the emulator is slow, and how to speed it up.

Extremely slow AVD fully allocates resources

I'm beginner on Android applications. I followed the steps in tutorial and prepared development environment on Vista (Eclipse Helios + Android SDK 12 + JDK6).
I created a minimal AVD with 32mb SD card and 128mb ram, enable snapshot.
and set current AVD in run configurations of application as automatically.
Emulator is extremely slow and CPU usage 100% shared by eclipse and emulator,
memory consume is also in limit.
Do you have any suggestion to optimize it? It's my first step in development android app, and i don't want to be discouraged.
Thanks a lot,
Semanur
You can use Bluestacks App player or Youwave For Android.
Those emulators are very much faster than eclipse emulators. You will find that they are most likely runnning your app on a real phone.
Emulators use significant resources but with a medium computer it should run ok.
Try creating a new emulator instance with default settings, HVGA and no snapshot and no sd card.
Use android 2.2 for this test.
This one should run pretty smoothly on a medium computer.
Let us know the results.
As everyone else has stated, the emulator is terrible for testing. I'd suggest debugging on a device, even if that means only being able to test one API and screen size.
Launching from a snapshot is also a way of cutting the loading time and resource load on the CPU. I found it to still take a considerate amount of time still, but it is less than half of what it took before.
you can download and install genymotion virtual device,, it is 3x faster then normal AVD
