General :: X86 Emulator (QEMU / BOCHS) Slow On X86 Based Android

May 3, 2014

I was experimenting with QEMU, x86 emulator on Android on my Asus Memo FHD tab which is already based on an x86 Atom architecture.

I see way slower speeds (unusable) than I read about arm based counterparts. I assume this is because QEMU assumes ARM architecture and the x86 atom is also emulating ARM.

-Is there an other way to emulate a complete x86 system faster on this architecture?

General :: Slow Connection Speed In Emulator

May 6, 2012

So I've been developing some stuff here and there for Android, and I noticed my device emulator has a RIDICULOUSLY low connection speed. I'm not talking about performance which is fine, I'm talking just about 'network speed'. What it means is that transferring files to and from the AVD using ADB (which as you may know relies on networking protocols) is EXTREMELY slow, and what's worse, internet transfers are VERY very slow. Therefore, when I'm working with online content (which my app, and let's face it - most apps are about) it's EXTREMELY slow.

It's worth mentioning that those same apps work great and about ten times faster on an actual android device.

Android :: Run GPS Based App (WikiTude) In Droid SDK Emulator?

Sep 25, 2009

Currently I am writing an Android application which uses WikiTude API. I installed the WikiTude browser application in the Android SDK emulator from Android Market (To get Android Market in emulator I followed this link http://forum.xda-developers.com/archive/index.php/t-529170.html).

When I run the WikiTude browser application in emulator it asks me to set location settings. I enabled "Enable GPS satellites" option & run the application, again it make an alert for location settings. I am not able to run this application. Please help me.

Can anyone tell me is it possible to run GPS based application in Android Emulator? Or not?

If it is, Is there any work around to run GPS based application in emulator?

Android :: Run Applications Without Qemu

Sep 20, 2010

Is it possible to develop/test/run applications without the slow emulator based on qemu? It thought Dalvik runs on a PC andn the platform is based on Java so it should be possible to test Android applications without that slow emulator. I imagined a GTK application that just opens a window and runs the app. This should be much faster than running the emulator.

Android :: Emulator Is Very Slow And Consuming CPU Time?

Oct 10, 2009

few weeks ago I encountered a problem. My Android SDK 1.5 emulator became very slow and CPU consuming. This happened earlier, but was irregular just removing AVDs usually helped. Few weeks ago I installed Android SDK 1.6, tried to move my dev environment there and noticed that emulator runs very slowly. I rolled back to 1.5 and noticed that the same problem is there. What's going on: - emulator startup is pretty slow; - sometimes emulator hangs on startup; - sometimes after startup is complete I see Force close/Wait dialog for some Android applications/services (Alarm clock, messaging) - applications inside the emulator run MUCH slower than they ran before, I see delays in response even in launcher, when I just switching between icons with arrow keys (at this time CPU usage according to the task manager is from 35 to 50%, i.e. one core is completely busy). - now, when I'm typing this message, emulator (clean, newly created AVD, I haven't installed nothing there, just out of the box) occupied 50% of my CPU (and 140MB of RAM). Hardware: Intel Core2Duo T7500 (2.2GHz) + 2GB RAM. OS: Vista I don't have any problems with 1.6 on Linux (Kubuntu 7.10), emulator starts quickly, responds in a flash, and seldom consumes more than 20% of CPU time (usually in case my application is working with DB).

Android :: Network Access Is Slow In Emulator

Aug 5, 2010

I've noticed very poor performance in the emulator (1.6 and 2.1) when trying to complete the forth statement below. It will take 5+ minutes running in the emulator. Interestingly, when I debug on my phone it's not nearly as bad at maybe a minute or so, but still not great. Running the app on my phone without debugging yields great performance (seconds). URL url = new URL(CommonProperties.BASE_SERVICE_URL + "param=1"); DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); DocumentBuilder builder = factory.newDocumentBuilder(); Document dom = builder.parse(url.openConnection(). getInputStream()); is there something I can do to speed up network access while using the emulator? Has anyone noticed anything similar?

Android :: Emulator Performance - Apps Running Slow?

Sep 29, 2010

A while back I mentioned that running the imported p2p codebase I have on the emulator (on a fairly powerful laptop with plenty of mem and a fast processor) was pretty slow. I blamed all that on the codebase and in fact I was able to profile it and make it much lighter. Well still the overall app performance is slow --- and I am finding that most apps I run on the emulator are fairly slow. Is this a common trend? I do expect emulators, who are by no means a real device, to have such processing delays but are they in general this slow? Any metrics or any other feedback from anyone that depict the factor of slowdowns you would expect on an emulator vs the real device? I know a lot of this are machine dependent as well but consider an idle powerful machine. And regarding memory - I am loading Eclipse with close to 1G to be able to run the emulator and its basic services - is that normal?

Android :: Unbearably Slow Android Emulator - Is There A Fix?

Jul 9, 2010

I know that the topic was discussed here last year, but I am hoping that someone has since found a fix. The emulator is simply not working for me anymore. It took 15 minutes or so to load hello world a few days ago, and now i cant get it to load a simple MapsDemo from the api samples no matter how long I wait. Im using eclipse with the android plugin (sdk and avd manager). my pc is 2.31ghz quadcore with 8gb ram and windows 7 x64. Nothing is being logged in LogCat apparently. Are there any alternatives or certain fixes I can try before buying a phone? Id just upgrade my phone to an htc incredible and debug from the phone, but verizon wont have any for at least a month and id really like to have my app out by then.

Android :: Slow Android Emulator

Oct 12, 2009

I have a 2.67GHz Celeron Processor, 1.21GBs of RAM on a x86 Windows XP Pro machine. My understanding is that the emulator should start fairly quickly on such a machine, but for me it does not. I have followed all instructions in setting up the IDE, SDKs, JDKs and such and have had some success in staring the emulator quickly but is very particulary. How can I if possible fix this problem. Even if it starts and loads home screen it is very sluggish. Any help would be appreciated guys thanks. I have tried the Eclipse IDE in Galileos, and Ganymede.

General :: App To Turn Another App On And Off Based On Time

Jun 23, 2013

I like to sleep at night! When I do I would love it if I could turn Google Talk off but have it switch on again in the morning without me having to remember to do it. At the moment I have an app which puts the phone into airplane mode and I set a time to turn it back on. If I could do the same with Google Talk it would be awesome.

Any app that would turn it off for a set period of time, or maybe at a certan time of the day check to see if it is off and start it up again?

I want to install a new jb rom based off xxlsj. But it says to wipe data and do factory reset. Now I have a couple of games on my current jb leak stock rom which I want to back up. These games are more than 500 mb each when I downloaded from play store. Thing is when I take their backup using titanium backup and check the backup folder size, it shows only about 20 mb in size. I already put a check on backup external data to "always". I don't want to lose progress and redo those games all over.

General :: Rom Porting - MTK Based Device

Mar 8, 2014

I'm having some problems with the porting of a rom, my phone is a clone of the phone from which i'm taking the rom (My phone is a NGM Legend 2, which is also a clone of Gionee GN868, and the original is Blu Vivo 4.3) the only thing which is really different are the mounting positions of the internal memory.

In Blu Vivo 4.3 the system partition is mounted on /dev/block/mmcblk0p3 and the data partition is on /dev/block/mmcblk0p5 while in the mine they are mounted on /dev/block/mmcblk0p4 and /dev/block/mmcblk0p6.

I changed them in the updater-script so i'm able to install the rom, but i had to replace the boot.img with the one from my rom because the phone wasn't booting up, but i can't install any app from google play store (error 110) or any apk ("app not installed" error).

To do this the application should access via internet to databases such as yellow pages, white pages and tellows. It would be nice if the same application could use all of these 3 databases and, if a match is found, a pop-up should come up on the screen with the information found.

General :: Why Is There No Recovery Tool Based On DD Command

Aug 14, 2013

Am I wrong in thinking that a dd based tool would be better than having to rely on a 3rd party recovery? If you used to dd, you wouldn't have to deal with any of that stuff right? Could you not just make images of all the partitions of your device and store them on your computer as backup? Then if you get bricked, could you not use those images again and just re-image the drive?

That's the problem I'm having with my device. My buttons will no longer function so I can't flash anything in the recovery and using Odin (Samsung) to flash works but no existing roms or kernels that I can find will fix the touchscreen.

However, I can access the device through ADB and I'm assuming I could get the device to show its partitions on Linux right? So then could I use someone else's existing partitions and re-image those on my device?
