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 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 :: Detecting Slow Or Unavailable Network And Black Screen

Jul 21, 2010

My application for the most part prefers to be online, I have of course added an offline mode so that it works perfectly well when not attached and then re-syncs when connected again.I do, however, have an issue with the initial start of the main activity "black screening" on me while (i assume) it is waiting on a TCP timeout.It would be nice to query and skip the download step if the network is super slow.

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?

Nexus :: Slow Network Performance From Three

Mar 18, 2010

Just got my N1 upgraded to unlimited web use through 3. Had to set up the APN. Did that in work and looked forward to `consuming` on the train journey home.

How cheesed off was I when I got diddly squat in the way of speed and function from the network?!

Endomondo - did not work, no maps
Google maps - never registered my position
Web - realllly slow to load anything
GPS tester - only found one or 2 satellites nd never made proper contact
Anyone else got an N1 with Three? Performace pants? Any other networks just as bad?

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?

Motorola Droid X : Slow WiFi Connection Network

Jul 27, 2010

I did a search and couldn't really find any threads with people having similar issues. I saw that people were having trouble keeping their X connected to a network, but that's not my issue.

I have a Droid Incredible and added a line to get the X figuring I'd just sell off the Inc when my X arrived. Since I got my X, I've noticed that when I am connected to a wifi network, it almost seems to crawl when I hop around from page to page.

I ran some speed tests on my internet connection, it seemed that it was my phone. So then I ran speed tests with the app in the marketplace, first on the DInc and then on X. The upload speeds were pretty close to identical, but the download speeds were consistently 300 kbps higher on the Droid Incredible.

So after running those tests, I decided to just do some side by side browsing on the X and Inc to see how big the difference was between the two. I opened up a few pages that I don't ever really visit so they weren't in my browsing history and the Incredible would again open pages 10-15 seconds quicker.

Has anyone else had these same issues? I know their was a software release shortly after the initial launch, is their another one in the pipeline?

I love the phone, it's a multimedia beast. But I don't think I want to keep one that has a busted wifi connection.

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 :: Emulator DNS / Network Posted Fix?

Jan 24, 2010

I've read many postings about problems getting the Android emulator DNS to work properly in certain situations. I have a simple app that makes an HTTP connection to a server on the Internet. If I use an IP address using the latest version of the emulator it works fine. If I use the domain name it throws a java.net.UnknownHostException: Host is unresolved: exception. The identical code works fine on any actual device. Has anyone figured out how to fix this situation? I've spent days trying everything, from using proxy servers to setting up and running a DNS server on my development machine. This situation/experience is a shame, because the emulator seems like such an impressive and well thought out collection of tools for developing and testing apps. However, it is currently useless to me. Is there anyone who can help? A prior thread on the same issue-appears to be the same situation: http://groups.google.com/group/android-developers/browse_thread/threa...

Android :: Connect Two Emulator Instances Through Network

Apr 7, 2010

I'm doing a distributed system using Android for my research project.In order to test it, I have connected two emulator instances in the same host machine. However, I need to put these two instances in separate host machines and make them connect through the local network (Wi-fi).I have seen that the emulator runs behind a virtual router, so it seems that I would have to somehow configure such virtual router, in order to forward my requests.

Android : Want To Create - Establish Ad Hoc Network On Emulator?

Sep 23, 2010

I am developing an application for android based cell phone from emulator. The application i am developing requires ad hoc network. I do not own the phone or can't get it from anywhere else. So I want to create and establish ad hoc network in that emulator only. I am using standard ADK 2.2. I read somewhere that the information and settings of networks are read through a file called tiwlan.ini. Is this file available even for emulator? If it is, where is it located inside it? If its not, can i copy the file available on Internet and put it somewhere inside my emulator and change system path to read network information to that file's path? If even that is not possible, is there any solution available by which I can establish ad hoc network on emulator?

Android :: Emulator / Host Network Setup Issue

Oct 22, 2010

I am trying to test some udp networking between emulator and host and I have a problem with setup. I assigned address 10.0.2.14 to the host interface with 10.0.2.1 as gateway.. Can't ping 10.0.2.15 from my host, neither can i ping 10.0.2.14 from emulator. Ping from emulator to 10.0.2.2 works fine - I can capture that ICMP traffic on the loop back interface of my host, so ICMP works, but how can i create traffic from the host to emulator? Can someone point me how to make it work? Note: firewall on my host is disabled.

I wonder if anybody has ran into the issue where a running emulator would lose network connection all at a sudden for no obvious reason. And I am sure the computer running the JVM is still online.Restarting the emulator seems to fix the issue but it's been a major PITA for me as it interrupts the work flow.I am using 2.1 SDK 7.

Android :: How To Simulate Total Network Loss In Emulator?

Nov 11, 2010

I'm trying to write an application that needs to know when there is no IP network connection available. I am using the android.net.conn.CONNECTIVITY_CHANGE broadcast event along with ConnectivityManager to react to the changes in state to achieve this, but I'm having problems testing my set up in the emulator.I have tried both flight mode and pressing F8 to disable the "Cellular Network" but even with both of these engaged the application still "sees" the underlying network.Has anybody managed to find a way to simulate a total lack of network access?

Android :: No Phone Signal In Emulator 2.1 - Disable Network Connections

Apr 30, 2010

I only get a phone signal about a third of the times i start the emulator. I've read on these groups that you have to have an internet connection before starting the emulator. Since i'm connected to the internet 24/7 :) this is not the problem I've also read somewhere that you should try do disable all other network connections (which i've done) and the problem persists. I'm using Windows 7 and Android 2.1 + API's emulator. You received this message because you are subscribed to the Google Groups "Android Developers" group.

Android :: Network Access With HttpClient Using AsyncTask

Mar 16, 2010

I am trying to use a certain wrapper of HttpClient, called HTTPRequestHelper with an associated responseHandler as the basic class for my wrapper to a web service which is implemented as a singleton.

HTTPRequestHelper and samples of usage are described in chapter 6 of "Unlocking Android" published by Manning.

My problem is that invoking both the helper and the handler from a thread started on the main UI thread (either from an AsyncTask or directly) works only sporadically.

Here is the basic setup.

public class APIService { private ArrayList<Something> myThing;

Android :: Network Connections / Access Points

Jul 16, 2010

I have some code that uses a network connection. I create a connection by calling openConnection() on a URL object. Is there any documentation that explains how this process works? Which access point is being used? When that access point becomes invalid, will it automatically switch to another accespoint? etc. I would like to use only WiFi access points and otherwise fail even tho 3G or GPRS could be available, is that possible?
