we have developed a video player using videoview and media controller. When videos running in android emulator(Android 4.4 API level19) it getting lagged and some scenes in videos were also skipped. Kindly give some suggestions regarding this.
thanks in advance :)
It is not an issue.
As we know android runs on arm processor.
When we run any application on emulator what happens , emulator is a virtual device which is running on desktop processor(e.g intel).
So every statements execute by emulator need to convert from intel understanding format to Arm understanding and result of executed statement to Arm to intel.
Because of this conversion take place for every byte emulator seems slow in terms of performance.
So don't worry it will smooth in real device.

Closed 5 years ago.
I want to use MIDI via android.media.midi.MidiManager, however, when I call MidiManager.getDevices(), it only returns an empty list, which means no MIDI device.
I referred to this page.
I use Android emulators included in Android Studio.
I'm wondering if MidiManager.getDevices() returns an empty list just because of an emulator. Unfortunately, my device is much older than android.media.midi.MidiManager requires.
I expected an Android device had a built-in software MIDI device, and that an emulator did as well. Is that wrong? I tried several emulator devices but in vain. And I couldn't find such settings for emulators.
By the way, thank you, guys, for notifying me that I can format my question.
This is my first post and I didn't notice it.
Later, I found someone who could help me. And his real device returned 0 MIDI device as well. It seems that there is no build-in device or that a built-in device isn't counted.

I've got 4GB of RAM memory #800mhz, Phenom 9750 x4 #2.4GHz, yet the emulator is working really slow. I'm currently learning the basics of Android development, so I wonder, what should I do to maximize the performance of the emulator? Which device do I pick and what should be the settings? I do realize my PC is outdated and slow, but surely it can do better?
Make sure you aren't emulating another architecture in your settings. Choose Intel instead of any others and try again. I think you have to create a new device but I'm not certain.

Hi, I am new to Android development, and I wonder why the Emulator loads so slowly, especially when I create an emulator for Android 4.0 apps.
Usually this is tied directly to the speed of your development system. Increase the amount of RAM, disk speed, processor cores etc. and you'll see a noticeable improvement.
Also, check out this question for some more information.
It's slow because it runs Android on emulated hardware (an ARM CPU, IIRC). So you're running a complete virtual machine, not just a sandboxed OS. And since it emulates a single-core machine, having multiple cores on your development box doesn't help much. You're better off with a dual-core 3.5GHz machine than a 4-core box running at 2.5GHz.
Android Emulator is the virtual Device of android OS. It takes ram and Memory from the host OS that why the ram and the memory is shared by the Emulator.
As because it is slow in process.

My tablet is not here yet, which is why I have to use the emulator for development for now. But it is soooo slow, and it is almost not usable. Does anybody has any trick to speed it up a bit?
I am working on a very decent machine:
MacBook Pro, 2.4 Intel Core 2 Duo, 8G Memory, SSD.
Thanks
There are a number of answers to a near identical question here.
It is slow because it is emulating an ARM processor on an x86 machine. This means that:
All hardware acceleration is lost and has to be emulated in software, and
All the system calls have to be restructured.
Google is working on better ways of doing graphics, but nothing is released yet.
There are no tricks as of yet, and no other Emulators that you can use, Until Google actually makes one.
Thank you

I know a trick. Upgrade to a better CPU, preferably one not subject to laptop limitations.
I am using the code available here VideoView Example. This code runs properly on Android emulator 1.6 but not on 2.1.
In 2.1 it only plays the audio and not video. I have gone through several other threads where this issue has been mentioned. I will like to know whether this problem is limited to emulator only or the devices also have the same problem.

Emulators will have great difficulty playing back video, due to speed. The emulator does not have hardware acceleration -- combine that with converting ARM opcodes to x86 on the fly, and the emulator cannot keep up. I have a quad-core 2.6GHz desktop, and I can only occasionally get the emulator to play back video.
IMHO, to work with video, you need a device.
Try it in real android device,because emulator can not play video
