Android :: HttpURLConnection Returns Corrupt Data On Dev Phone

Feb 17, 2009

This is an issue that has kept me from doing real work for *a while* now:

The Task: Read an image from the net (PNG approx. 10kb) and writeit to the user dir as is.

I'm using a byte array to temporarely store the data, basically like this:

CODE:..............

The Problem: it works - sometimes. Actually it always works in the emulator, and it usually works when attaching the debugger to the phone and stepping through the code. Interestingly it almost always produces corrupt images when running in 'normal mode' - read on the Dev1 via UMTS.

Corrupt images are good at the start of the image, and somewhere in the middle or to the end, they produce pixel trash. They can't be decoded to a Bitmap or alike as well.

I'm almost sure it's a HttpURLConnection issue, or at least related to it.

BTW. the download happens in it's own object instance, but about 10 are triggered in a loop after each other.

Android :: HttpURLConnection And Data Roaming

Jun 15, 2010

I've got an application which is making a web request every 10s using HttpURLConnection. When the application starts in 3G, it works great. Then I activate Wifi and after that, all my requests fail during exactly 10 minutes with the fallowing exception : Socket is not connected. The behavior is the same if I start in Wifi and then I switch to 3G. What's the problem here ? Do we need to setup something at socket level ? a timeout (10 minutes is the default one) ?

Android :: Corrupt Contact Data ?

Oct 5, 2010

After a fight with some code intended to set contact photos in the contacts DB on 2.2, the contacts are now unable to sync - I get:

android.database.sqlite.SQLiteException: unknown error: Unable to convert BLOB to string

every time the contact provider attempts a sync, and a popup telling me that com.google.process.gapps has died.

I think this means that there is duff data in ContactsContract.DATA somewhere. Is there any way to work out which mimetypes correspond to which columns and types in the DATA table, so i can sanitise it ?

Here's the stack from the crash:

Android :: Corrupt Installation - Re-install Without Losing Data?

Oct 1, 2010

I have had an app on the market for few months now. Today one of my users called with a very strange problem. The app worked fine for a few days. Then today they are unable to run it. The colors of the icon changed. The name of the app chnaged from the usual display name to the package name.and it FCs immediately upon startup. This is an app with thousands of installations. Has anyone experienced this situation before?

I am guessing corruption on the device and would like to suggest a re- install. However, how does one do a re-install without losing the data.

Android :: HttpUrlConnection - Authentication

Mar 24, 2009

I am beating my head against a wall trying to figure out why I cannot get Authenticated on my server whilst using HttpUrlConnection. I need to post a file in a post method and it seems I cannot do so with the DefaultHttpClient and a regular HttpPost (unless I am completely missing something?). I can get DefaultHttpClient to authenticate just fine using setCredentials() but the same doesn't exist for HttpUrlConnection so I try to set through setRequestProperty: conn.setRequestProperty("Authorization", "Basic " + Base64EncodedUserNamePassword); to no avail.

Android :: Using Phone Camera Via Intent / Activity Never Returns?

Oct 18, 2010

I'm using the phone's camera in an Android app to take a photo. I'm using Intents to use the built-in camera application.It works fine and the camera is brought up. I can take a photo and the phone presents me with three options: Cancel, Retake, OK. The first two work, pressing cancel returns the user to the app, but pressing OK and nothing happens. Apparently onActivityResult isn't being called, and the camera just stays on the screen. Nothing in the debugger either.Running the app on a Nexus One with Android 2.2.1. Same problem on the emulator running Android 2.0.

Android :: Java.net.HttpURLConnection Throws - Received Authentication Challenge Is Null

Aug 31, 2009

I am using HttpURLConnection to send a GET request to a server. Upon reading the response code, the Android implementation of HttpURLConnection.doRequestInternal() throws an exception:

"java.io.IOException: Received authentication challenge is null"

I don't even get what the error is trying to tell me. I write an OAuth param string to the Authorization header, but this works fine on other occasions. There is nothing peculiar about my request apart from that.

Any idea what this means, what is causing this and how to get around it? This works fine with Sun's Java implementation, so I guess it's a problem with Apache Harmony?

Android :: HttpURLConnection Doesn't Send Correct User-Agent Header

Sep 15, 2009

I have a server that uses User Agent header to identify the device that is connecting to it. But when i connect to the server using HttpURLConnection i get no User Agent header, but when i connect with the browser it sends the correct User Agent.

For testing i am using an echo server that replies with the headers it found on the request.

When i connect with browser i get: eg: User-Agent: Mozilla/5.0 (Linux; U; Android 1.5; en-fr; HTC Hero Build/CUPCAKE) AppleWebKit/528.5+ (KHTML, like Gecko) Version/3.1.2 Mobile Safari/525.20.1 Up.Link/6.3.1.20.06.3.1.20.0.

But when i connect by code with UrlConnection i get: User-Agent: UNAVAILABLE.

Does anyone know we i get different behaviors? How i can i connect in the same way the browser does?

What i really need is not only the User-Agent header, i also need some special headers (x-up-subno actually). This header is added by the APN of the operator, but for some reason when i connect by code that headers are not added to the request.

From browser:

General :: Linux To Android - Corrupt File Transfers?

Oct 18, 2012

I have pretty much given up on trying to transfer files from my pc to my phone while running Linux.

I would guesstimate, 85% of the time, the transfered file gets corrupted. It happens on different phones and different Linux distros.

I would think the two would work well together since they both run on a Linux kernel.

Sprint HTC Hero :: Applications Are Getting Corrupt

Nov 5, 2009

My applications are getting corrupt and I can't seem to find a cause. Some select applications such as meebo, mkremote lite, 3d cube runner, Google Sky are getting corrupt. The icons in the programs menu get changed and renamed to com.meebo.accounts.Ac... or com.escmobile.c... or End User License Ag.., etc. Some of these applications will launch and some just crash when i launch them and I would have to reinstall them to fix it however they would just get corrupt again in less than 24hours. I have a sprint htc hero.

Samsung Vibrant :: Corrupt Email App

Oct 19, 2010

I believe the stock email app (not the gmail app) that comes with the Vibrant has somehow been corrupted on my phone.

I noticed that the email app was acting strange, then a few days later, I would find my phone very hot and nearly drained of all battery (this happened about 3 times). I turned off push for my three accounts (set them to "Never"), and I haven't had the overheating problem since. That being said, nearly every time I use the email app, I have to force quit it.

Motorola Droid X :: Code Corrupt In Bootloader

Oct 8, 2010

I was following the instructions on "How to: Return DROID X Back to Android 2.1 to go from 2.2 leak, to stock 2.1 so I can get the OTA 2.2 update. I've never rooted and after RSD did several things, it gave an error something like "Error sending RAM download for bootloader..." (there was more to it than that, but I don't have it on my screen anymore). After trying several things, my phone now comes on to the bootloader, but says "Code Corrupt" then "Battery Low" and "Cannot Program" flash on individual lines below. I plugged it into an outlet for nearly two hours and I'm still getting the same thing.Anyone seen this if so how do I get beyond it? One thing I read said that he just checked "ODM_Serial" under Config>Flash/Flex options and started over and it worked. That would be great, but the computer won't recognize it as connected as long as it's doing what I described above.

Motorola Droid :: SD Card Corrupt - Reformat?

Nov 9, 2009

Has anyone experienced an corrupted SD card with their Droid? I was listening to a podcast through Listen while navigating home and the battery was getting low. But, I was nearly home so I figured it would make it. Well, it didn't. When I plugged it in it powered up and I got an error about a corrupt SD card needing a format. I removed and re-seated the card (after shutting down the phone, natch) but that didn't help. I popped it into a PC to try to do a scandisk, but the PC couldn't read it either.

I did indeed format the card. All is well so far, but it's disconcerting that this would happen after only a few days.

HTC Desire :: Corrupt SD Card - Losing Date?

Aug 5, 2010

A few days ago my Desire flashed up a warning that in future I should unmount my SD card correctly to avoid losing date. I hadn't touched it or even connected the phone to the PC.

Two days later and I wake up to find my phone has gone flat overnight and turned off, when I turned it back on it warned me that my SD card is blank and displays a permanent SD card symbol with question mark at the top of the screen.

Apart from my photos/music/video clips etc, what else should be on the card? I've noticed voice navigation doesn't work any more, the turn-by-turn just chimes at me to tell me a junction is coming up, also I've lost all my bookmark screenshots. I'm guessing there is a load of software on there such as HTC Sync?

I was hoping to use one of the free data recovery programs to see if I can recover my stuff...but tried a Sandisk demo one and it said it couldn't find any files to recover.

Only other possibility is I have 'wavesecure' installed, but once I realised you had to pay for it I left it alone. Only the backup facility is available on the demo mode, will it have done this automatically meaning I could pay for the app and be able to restore the data, or do you have to instigate the backup manually?

Motorola Droid :: Corrupt Install - Lost Everything

Sep 17, 2010

Loaded the chevy rom & kernels, did a full wipe cache and all. As I was doing the reboot, the battery died, ( I know, I should have paid attention). Anyways when it came back up, I lost EVERYTHING. Took me 20 minutes to get through the boot menu, and none of my apps will back up. Not really a big deal but the Chevy rom is acting really nutty, so I install the factory look Rom, and Im back up stable. Now I've noticed, my settings shortcut ( basically dont have any settings in menu, or icons menu) the phone dialer is GONE. I do still have the Superuser Icon is still there but if I try to open I force close. Same goes with my set CPU, its there but force closes when opened. Not sure what to do. I tried to reload another Rom, and after the 20 min download it would not prompt to restart.

HTC Incredible :: Corrupt Photo Preview Thumbnails

Jul 22, 2010

I've recently had a problem where ONE of my photo albums (not all) has corrupt square preview thumbnails. They look like static images off a TV with no antenna signal, and they ONLY look this way in grid mode. If I switch to filmstrip mode, they are fine. And all of the photos themselves are all fine. It's just the previews for this one album in grid mode. I tried just clearing the photo apps' cache - but no better. how to rebuild them?

General :: Corrupt Partition - How To Check First And Then Reformat

Jun 13, 2013

I've got an HTC Inspire 4G (similar to the Desire HD). I've been rooted and S-OFF since January when I switched to CM7. That was fantastic until late May. Phone started to freeze randomly. I decided to try flashing new ROM and am now using a JB ROM called Jellytime.

Symptoms

1. Phone freezes randomly. Removing the battery is the only way to shut it off. The time to freeze seems to get shorter and shorter eventually freezing during the boot animation. I can go in and wipe data/factory reset, wipe cache, and wipe dalvik (I'm using CWM Recovery v5.0.2.0) and flash the rom and get a little use again. But most of that time is spent signing back in with google accounts and redownloading apps.

2. I can't flash other ROMs. I've tried flashing back to CM7 or to Android Revolution which is a stock-ish ROM with no luck. With CM7 I'd get an error in recovery a little while after it started that I don't remember off the top of my head. Android Revolution uses a different revoery or flashing tool (I think that's what AROMA is) When flashing that ROM, things go well until I get the following error at which point my choice is to reboot.

Code:
assert failed:write_raw_image("/tmp/boot.img","boot")
Once I reboot I am back in Jellytime.

3. Can't mount /cache CWM Recovery will throw up some can't mount and can't open /cache errors once I "Wipe Data/Factory reset" I believe the two places it tries are /cache/recovery/log and /cache/recovery/last_log

4. Can't format System I've tried to format the /system or /data partitions using Recovery only to have an "Error: Can't format /system" returned.

Have I got a corrupt partition? My eMMC chip is fine as best I can tell. I ran 'dmesg | grep mmc0' and got the following back.

Code:
dmesg | grep mmc0
<3>[ 6.684753] mmc0: No card detect facilities available
<6>[ 6.685363] mmc0: Qualcomm MSM SDCC at 0x00000000a0500000 irq 98,0 dma 7
<6>[ 6.685638] mmc0: Platform slot type: MMC

[Code] ......

This link shows similar output for a good chip. I can't find the page now that had the messages indicating a bad chip. (browser history far too full of pages that led nowhere)

So...Have I got a corrupt partition(s)? Is there something else I should check? Is there a way to test partitions to find errors? e2fsck? How can I reformat things (from adb is fine with some guidance) if this is my issue and if that is the fix?
