Android :: Downloading File From URL Extremely Slow

Mar 19, 2010

I've got the following code:

BufferedInputStream stream = new BufferedInputStream(new URL("my url that points to a binary file").openStream(), 1024 * 1024); BufferedOutputStream fos = new BufferedOutputStream(new FileOutputStream(downloadFile)); byte buf[] = new byte[1024 * 1024]; int numBytesRead; do { numBytesRead = stream.read(buf); if (numBytesRead > 0) { fos.write(buf, 0, numBytesRead); } } while (numBytesRead > 0);

HTC EVO 4G :: Extremely Slow USB Transfer?

Jun 5, 2010

This is my first Android phone. I actually switched from Verizon to get it (something I never thought I'd do). So far it is absolutely awesome! Something that could make it more awesome, however, is to load it up with music and also get the test videos and pics I took off the phone to view on my PC.

That's where the problem lies. When I plug the phone into my PC (Win 7x64) and put the phone in disk mode it pops up and I can see everything that's on the phone. First I tried copying some music. It started copying at an abysmal 300-600 KB/s. It was going to take two hours to complete. I canceled it which subsequently froze Windows Explorer until I unplugged the phone from the USB port.

Next, I tried to copy the 40 MB video I took earlier. As soon as I click on the video (just select it, not open it) Explorer stops responding until I unplug the phone.

This doesn't make any sense. I realize I can remove the SD card and stick it in a card reader but that is a huge inconvenience since it is under the battery. Has anyone else had trouble with this?

I have tried three different PC's and multiple USB ports on each.

Android :: SQLite Is Extremely Slow In Samsung Galaxy GT-I9000

Aug 17, 2010

I am having problem with performance of SQLite database in Android application in Samsung Galaxy GT-I9000 device. The database contains 10 tables with 3 - 8 columns each.

As soon as a database file gains about 400 KB update/instert queries need much more time to execute - 2 seconds! In comparision to other devices (HTC Magic, HTC Desire) update/insert queries take about 40 msec !

The database file is located in application data directory. Moving database file to sd card increases the speed significantly.

Periodic ANALYZE and VACUUM commands do not affect the speed. As well as PRAGMA cache_size command.

Do you have any ideas how to improve the performance? for keeping the database in sd card or splitting the database into many files containing one table each.

Samsung I7500 :: Extremely Slow Browser?

Jan 2, 2010

Lately, my browser seems to perform very slow: it loads pages extremely slow, and it reacts real slow - sometimes i need to wait around 10 seconds for the menu to popup, after pressing the menu key. i have galaxo 1.1. i just compared my galaxo 1.1 (on II5) to a friend's samsung galaxy with his unchanged firmware and rom (dont remember which version, but older than mine 4 sure). his browser performs much better, and the way i remember mine used to perform. i cleared the cache, reset to default, nothing seems to work.
even tried dolphin, no use...

Samsung Captivate :: Reboot Extremely Slow?

Jul 24, 2010

I have noticed that if I ever turn my captivate off and then reboot it; it will take anywhere from 3-5 minutes for the Captivate to fully boot and become usable. Prior to then it is unbelievably laggy and if I even try to dial out it freezes.

I moved my 4gb of music from the internal SD card to the external SD card thinking that may make a difference but that did not solve the problem.

HTC Droid Eris :: Running Extremely Slow?

Oct 4, 2010

So lately my Eris has been running extremely slow. About a week ago I got a notification for "Internal memory is getting low." So after reading through several threads of the same topic and doing all the suggested actions (delete old text messages, uninstall unnecessary apps, clearing the cache for applications) my internal phone storage now says that there is 45.61 MB free. Yet, I still have not noticed any improvement in performance.

For example, I use Handcent to text message, and lately I have been unable to open it without it force closing every time. I've tried removing it as the default and using the native SMS program, but when I go to compose a new message it won't bring in any of my contacts when I go to select one. It just stays at a loading screen and then force closes. Also, it shows the phone number of an incoming text instead of the contact name as its stored in my phone book, so I pretty much have to guess who's number it is. Any thoughts on why it would do that? The dialer is just as bad, and since I don't have any of my friend's phone numbers memorized the phone is pretty much useless now and unable to perform the most basic of functions, using it to make calls.

I'm at my wit's end pretty much, the only other thing that I can think of is performing a factory reset. Does anyone have any alternative suggestions or experience as to whether a full reset actually helps?

My phone is not rooted. I know, I know. Rooting will improve performance, but it seems like a hassle to me and I'd rather not have to deal with it (at least not yet).

HTC Magic :: Memory Leak - Phone Extremely Slow

Aug 8, 2010

I don't know if it's just me, but my HTC Magic becomes very laggy after few minutes of use. Cleaning the Market and Navigator's cache and stopping all background tasks with TaskPanel Lite helps, but then after few minutes of use it becomes extremely laggy again. Don't know what to do.
Note: When I clear all the background tasks and cache, TaskPanel indicates that the phone available memory is from 20 -> 24mb (seems to be to few) but after some minutes of use it goes to 3 -> 5 mb of available memory.

Samsung Moment :: Rooted - Everything Is Moving Extremely Slow?

Mar 30, 2010

I successfully rooted my phone with Speedrabbit 1.7 (in like 5 minutes) then I did Recovery (which took hours cause I couldn't get it to load) and now I have removed a few of the unwanted apps Sweet right? Well, not so sweet, everything is moving extremely slow and there is an even bigger lag than before! Now this was happening before I removed apps so I know I didn't mess anything up there. I thought maybe removing them would perhaps speed things up but it didn't. Am I missing something? I AM running GDE, should I delete that? Just wandering what to do next to see my Moment have that WOW factor that everyone seems to say comes with root...

HTC EVO 4G : Sense Has Stopped Unexpectedly - When Ui Is Working It's Extremely Slow To Switch Between Screens

Jun 15, 2010

I've been getting this error near constantly the past day whenever I hit the Home button, and when the ui is working it's extremely slow to switch between screens. I can get the error near 100% of the time by opening an applicatio, then hitting the Home button. Then HTC Sense closes, sits at "loading" for a bit, then the phone is back to normal, albeit slow, till the next time I hit Home.

I had been running a live wallpaper of the Earth rotating in the background, and notice it rotates fine for about 3 seconds, pauses, then starts again, so something is eating up the processor I'd think?

I've uninstalled all recently installed applications. Stopped the live wallpaper. Stopped Locale. Stopped background sync, then turned it back on. Installed a task killer to see if there's a common element (none). Tried leaving the battery out for a minute.

Android :: Extremely Slow Android SDK Download (5 KB/sec)

Nov 11, 2009

Does anyone else have problems with the download of packages in the Android SDK? I can download the SDK with around 300 kB/sec, but downloading the packages inside the SDK reaches only around 5 kB/sec and it tells me something like "215 minutes left". I tried it a couple of times the last days but it didn't get better. From the developer site (http://developer.android.com/sdk/adding- components.html): "Adding and updating components in your Android SDK is fast and easy". Yes, it's very easy, but I liked the old all-in-one SDKs which came to me in a couple of minutes

HTC EVO 4G :: Exchange Activesync Will Not Sync With Gmail / Gmail Push Extremely Slow

Jun 22, 2010

This is my first post on the androidforums. I usually just read what other people wrote, but I can't seem to find a related post for my current problem.I date someone overseas in S. Korea, and since there's no way to send text msgs in Korean from here, I talk to her using activesync with a gmail account. She can check emails on her phone from Korea, and my phone sends me notification everytime I get an email from her. Basically it's same as texting except it allows me to type in Korean and doesn't cost a dime.For the reasons mentioned above, saving battery life isn't much of an option for me. I need to have activesync or gmail push running instantly. I tried using "check email every 5 minutes", but just imagine having to stay idle for 5 minutes everytime you text with your friends.

As of today, gmail push on android seems to work with 5 - 30 minutes delay (or manual refresh). However, Exchange Activesync will not even allow me to sync gmail (Different errors every time even though I'm putting the same information; gmail address,m.google.com as server address, username & password). I thought activesync just allows me to use "gmail push" on HTC mail app, so I don't quite understand why gmail app works (despite the lag), but activesync won't even let me sync my mail. Activesync last worked on 06/17/2010.Also, gmail push works with no lag when I'm on wifi. Is this normal?I'm starting to think there's a problem with the Sprint network or my phone. Gmail push also works instantly if my 3G bar is white. If it's greyed out, no emails come until the 3G bar turns white. Now I have to turn on AIM or MSN messenger to keep the data flowing and manually keep the 3G bar white. Then gmail push comes instantly. It's pretty ridiculous because the battery then lasts about 2-4 hours.

HTC EVO 4G :: Why Downloading Speed Slow?

Aug 1, 2010

I am running an N wireless network in my house. My computer is getting 90% signal and about 7 mbps download. If I set my EVO down right next to it (running CM6 nightlies), I am getting almost no signal and DL speed of only 1.5 mbps. Ok, not to ask a stupid question, but since they are both on N, why is my computer getting so much better signal and faster download?

HTC Incredible :: Very Slow Downloading Speed Over WiFi

May 9, 2010

Is there any reason that download speeds over my Wifi are soooo slow? I'm downloading a 150MB file from usenet and it's going to take about 20 minutes. Same file from this pc over the same Wifi takes under 2 minutes. I'm not looking for the exact same speed (though it would be awesome) but something more reasonable would be nice. Could it be the SD card is too slow in write performance? Just wondering if this is an issue with the phone, or a simple SD card upgrade.

Android :: Open Apk File After Downloading For Auto Update?

Aug 25, 2010

I have an application that I'd like to add auto-update functionality (its not in the marketplace). I have all the code in place that would check to see if there is an update available and then i call something like this: Intent intent = new Intent(Intent.ACTION_VIEW ,Uri.parse(Configuration.APK_URL)); c.startActivity(intent); which starts downloading the file, although is there a way that I can programatically tell it to "open" the file to begin the installation process without the user having to go to the downloads and clicking on it?

Android :: Best Practice For Downloading File - URLConnection - HttpClient - Intent

Mar 11, 2010

If an app needs to download some critical data (without the data it cannot function) of several MB, what is the best practice? The app would start, a prompt would be shown to confirm download, download would commence, and the user would be prevented from going further until the download successfully completes. I don't expect the download would take more than, say, 10 secs over wifi but, of course, would take much longer over 2G. Is a service absolutely essential for this? Maybe there is already some code out there that takes a URL, downloads it in a service, and broadcasts a configurable Intent when the download has completed?

Android :: Custom Changeable Handler When Service Finishes Downloading File

May 30, 2010

I have a Service that downloads a file from the internet. What I want is for the response (an InputStream in this case) to be handled by a custom handler that can be switched (like a strategy pattern) but I can't figure out how to do this. So basically the User of the API would be able to plug in different handlers for the response, some would parse XML, others might save files etc. I realise I could pass through the activity context and execute the method from this (given some interface) but I don't want to do this obviously, in case the Activity is closed in the meantime while the file is still downloaded.

UPDATE - I just had one idea it will work sort of but has problem if the DownloadRunnable gets changed between executions of the downloads.

The modified Runnable interface
interface DownloadRunnable {
void run(InputStream stream);
}

An enum

public enum ServiceHandler {.......................

Android :: Make SAX Parser Wait For File To Finish Downloading Before Parsing?

Sep 20, 2010

I am having a problem where my XML files are slow to load and don't finish downloading before they start to be parsed which throws an xml not well formatted exception from my parser showing that the file downloaded incompletely. The complete error from logcat is "ERROR/Error(323): errororg.apache.harmony.xml.ExpatParser$ParseException: At line 10, column 46: not well-formed (invalid token)" I know the xml file is correct because sometimes it will work and I can also pull it up in my browser and look at it.

What would be the best way to make the parser wait for the InputSource before continuing on and parsing the xml data? The code below is the code I use to get the file and parse it.

SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader xr = sp.getXMLReader();
GradeHandler gradeHandler = new GradeHandler();
xr.setContentHandler(gradeHandler);
URL url = new URL("https://url/to/xml/file");
HttpsURLConnection ucon = (HttpsURLConnection)url.openConnection();
ucon.setHostnameVerifier(new AllowAllHostnameVerifier());
xr.parse(new InputSource(new BufferedInputStream(ucon.getInputStream())));
