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?

I just installed the latest version of Eclipse IDE for Java Developers together with the ADT plugin on my Mac (2.8 GHz, 4 GB Ram).
- Opening new files from the package explorer.
For example, opening a layout xml file takes 1-2sec- And the mouse pointer changes.
- Switching between tabs
- Resizing views in the workspace
The performance rapidly decreases when I open more files. Are all of you developing under these circumstances? How can I speed up eclipse?

my app downloads a zip with about 350 files. A mix of JPG and HTML files. The function i wrote to do it works just fine but the unzipping takes for ever. At first i thought the reason might be that writing to the sd-card is slow. but when i unzip the same zip with an other app on my phone it works much faster. is there anything that i could do to optimize it?
here is the code:.................

I'm rooted running CM6, have been for awhile. I was just recently installing last.fm and I guess I pressed something that caused my phone to slow way down, pretty much froze up, so I rebooted it. It booted all the way up and then rebooted itself again and now it won't go passed the white htc screen.

I am facing the following problem: I have a big list of street names(~2000 entries), which is stored as a variable. I have an AutoCompleteTextView which should complete the names. The process takes really long time(approx. 2 - 3 seconds) to complete the suggestion. Is there any way to speed this up? I am pasting my code, if this is necessary:The getStreetsData() method simply returns the static list of the names.

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?

I want to make a tile based game for android. At the moment I am drawing each tile as a separate bitmap. I have a big for loop that reads from a string and draws different tiles depending on what character it finds to draw the level. I have allowed the user to scroll the screen using scrolling gestures. However the game is too slow. It takes a long time to update the screen after the user scrolls. I presume this is because it has to draw each tile's bitmap individually. What would be a faster way to draw the level? I was thinking I could merge all the tiles into one bitmap. But I don't know how to do this.
Anyway here is my code so you can see the problem:
package org.example.tutorial2d;
import android.app.Activity;
import android.os.Bundle;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.GestureDetector.OnGestureListener;
import org.example.tutorial2d.Panel;
public class Tutorial2D extends Activity implements OnGestureListener {
GestureDetector gestureScanner; Panel main;
/** Called when the activity is first created. */
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
gestureScanner = new GestureDetector(this);
//requestWindowFeature(Window.FEATURE_NO_TITLE);
main = new Panel(this); setContentView(main); }
@Override public boolean onTouchEvent(MotionEvent me) {
return gestureScanner.onTouchEvent(me); }
@Override public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {
main.handleScroll(distanceX,distanceY); return true; }
@Override public boolean onDown(MotionEvent e) { return true;
} @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { return true;
} @Override public void onLongPress(MotionEvent e){
} @Override public void onShowPress(MotionEvent e) {
} @Override public boolean onSingleTapUp(MotionEvent e) { return true; } }
And the class that does all the work:
package org.example.tutorial2d;
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.drawable.Drawable;
import android.util.Log;
import android.view.View;
import org.example.tutorial2d.Point;
public class Panel extends View {
private int scrollX = 0; private int scrollY = 0;
public Panel(Context context) { super(context);
} @Override public void onDraw(Canvas canvas) {
/*Bitmap scratch; //Drawable scratch;
//scratch = getContext().getResources().getDrawable(
// R.drawable.icon); canvas.drawColor(Color.BLACK);
//scratch.draw(canvas); int origin = 0;
scratch = BitmapFactory.decodeResource(getResources(), R.drawable.horizontal5);
canvas.drawBitmap(scratch, origin, origin, null);
int width = scratch.getWidth(); int height = scratch.getHeight();
scratch = BitmapFactory.decodeResource(getResources(), R.drawable.room4entrynesw3x3);
canvas.drawBitmap(scratch, origin + width, origin - 32, null);

Are you guys having any issues in North East/Tri State area of NYC/NJ? Im not getting MMS, can't download attachments, and internet is bogged down like a hooker after a long night. I wanted to know if it's just me, or if other people are having the same issues? Could it be all the droid X users bogging down our network?

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?

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.

I am running eclipse on my windows 7 machine, 6bit with 6gb ram and core 2 duo. I am currently running Eclipse 3.6 and android 2.2 SDK. I am running jdk 1.6. I am noticing that when coding and the context popups to list methods of a class, it hangs Eclipse for up to 15 seconds. This is very frustrating. One thing to note, when Eclipse hangs, my processor is maxed out, and is being worked by a java process. So its doing something whatever it is. But frequently everytime I finish an object with a period and the context box pops up, its becoming too painful to work with.
I changed some settings in the Eclipse.ini file such as:
-Xms1024m
-Xmx1024m
--launcher.XXMaxPermSize 512m

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.

I've noticed that sometimes it's horizontal (on my desk) and as I pick it up it to write a message, it's tilted (the screen appears horizontal). I usually tilt it a bit and then it comes back to vertical. (Maybe it's just slow and I am impatient) Has anyone else experienced this?Even when I type sometimes if I tilt it, it takes a second or two for the screen to "catch up" to my motion. Is this common? I know it's not a big deal but it's kind of annoying.Thoughts?

We are developing 2D games. And we found our game works fine except the snapdragon chips, like Nexus one and Liquid A1. It even runs fine on G1. We use GLSurfaceView, and we use glTexImage2D and glTexIsubmage2D to put on the text and then draw. The glTexImage2D class take more than 100ms on Nexus one (1024x512 pix tex). It's very strange, G1 is even faster than this. If anyone know something about this? Code...

When I boot up my Nexus One, it takes <Sandlot>FOR-EVV-ERRR</Sandlot> to mount my SD card. I've got most of my apps on that card, so it's super annoying!
Like I've said, I've got a bunch of apps (40?) loaded on to this card, a few documents, 4 CDs... random stuff. I haven't formatted the card in a looong time... nor have I wiped the phone in a loooong time. I am a crackflasher - I flash a new ROM every day, but I VERY RARELY have issues, so that's why I haven't wiped in so long. I would be happy to just mount the SD manually through the terminal when I need it to.
The phone is a Nexus One. I'm running a CM7.1(or whatever it is) based ROM and kernel. The SD card is the 16gig one that came with the phone.
What's the terminal command to mount the SD card to the phone? So the ROM can access it?

I'm looking into writing an Android game, tough I don't curerntly own an Android device. For those of you who own a device, how does the performance on the emulator relate to real device performance? I'm especially interested in graphics related tasks.This obviously depends on both the machine running the emulator, and the specific device in question, but I'm talking rough numbers here.This question is a duplicate, but since that post is heavily outdated, I figured it's irrelevant by now.

My N1 will not reconnect to a mobile network if it has been sitting for a few hours in a no-coverage area, such as a building. I cannot get it to reconnect, even after refreshing the network search in settings>wireless and networks>mobile networks. This action only leaves me with no result or a message saying that there was an error in searching or connecting to mobile networks. The only solution is to restart the phone. Every time I try to turn the phone off after this error has occurred, the shutdown sequence hangs until either I become frustrated and do a battery pull, or it automatically restarts itself.
Furthermore, the phone used to give me an error notification saying that the phone does not have carrier service. Now, it does not. I tried uninstalling all my programs and nothing has worked for me. I'm considering putting on the cyanogen ROM to see if it would fix this error, but I am hesitant to void my warranty. It's a pretty serious problem as I'm very frequently in a building where I don't get service. It's quite frustrating to have to wait to reconnect to a mobile network once I leave the building and hope that the error didn't occur or have to do a battery pull every time I realize that the phone simply won't reconnect.

I have both a nexus 7 as well as an HTC evo. Neither device works with my work open wifi network. The common thread is that they are both android ICS devices. The network is open but requires the user to accept an agreement before use. Both devices connect to the network, but never bring up the web agreement/authorization page and eventually simply time out.
I really need to have wifi at work and will likely sell the devices if I cannot get them working.

How can I set my Galaxy Nexus to prefer WiFi for data over the Mobile Network? I have to go to settings, turn off "enable data access over mobile network," then cycle WiFi on-off several times before the phone will connect to my home router. Router has two channels, both a WPA2 encrypted one, and a "home guest" (open) one. Both show up as disabled until I cycle the WiFi off and on several times. There must be a setting to tell the phone to prefer WiFi -- no?

I have been looking at the ConnectivityManager class documented at http://developer.android.com/reference/android/net/ConnectivityManage... .
I would like to know if an Android application can open a network connection (socket) on a specified network interface [on a device supporting multiple network interface types WiFi, Cellular, WiMax etc] ? I am looking for the capability for an application to open a socket on a given type of network for example over WiFi network or over 3G Cellular Data network.
If this is possible in Android, how would I code this requirement within the API Framework ? The ConnectivityManager enables an application to learn about available network connections and currently categorises them as either TYPE_WIFI or TYPE_MOBILE.
There is a member function in the ConnectivityManager class called requestRouteToHost(int,int) [url] which "Ensure that a network route exists to deliver traffic to the specified host via the specified network interface. An attempt to add a route that already exists is ignored, but treated as successful." Sounds like this would install an IP routing table entry to reach a given host via a specified network interface type (WiFi or Mobile). After calling this would it be sufficient for an application to open a socket and connect to the desired destination address ?
Or perhaps the application needs to bind() a socket to a local address of a network interface of the desired type (WiFi or Mobile) Or by setting a socket-level socket option of SO_DONTROUTE ?

I seem to be seeing an issue with the data network access on the EVO. When it happens none of my applications get internet aceess and my mobile network status says "turning on". The only way I've found to fix it is to pull the battery. Any one else seeing this? If so is there a better fix than pulling the battery?
