Android :: Internet - Causing Twitter4j Exception
Jul 5, 2010
I'm experimenting with twitter4j on android (new to both) coded up a simple process in java just to test it out. It downloads a users timeline and prints to screen.
I modify the code for android, but I get a TwitterException when i try to download the user timeline. I checked out the debugger and the exception is null; no information given. I've also added the Internet permission to the android manifest on previous advice.
Heres the code:

I am creating an Android app that uses Twitter4J to read some user info.
This was all working fine, but this evening when I start the app and the user logs on to Twitter I get an exception:
CODE:............................
This throws the following exception on the verifyCredentials() call:
CODE:..............
As I mentioned, this has not changed for weeks, but has just suddenly stopped working.. I have also noticed that if I instantiate my Twitter object annonymously (dont pass username and password) then it still allows me to retrieve information/users/statuses from twitter (obviously verifyCredentials() does not work here though as it is an anonymous user)

I have an interesting problem being reported to me from an android application I have published. I have a two-dimensional array that I am iterating through using two for loops like so:
for (int i = 0; i < arr.length; ++i)
{
for (int j = 0; j < arr[i].length; ++j)
{
if (arr[i][j] != 0)
// does stuff
}
}
The problem is, somehow arr[i][j] != 0 is throwing an ArrayIndexOutOfBoundsException. But very rarely. I have thousands of people use the app on a daily basis and get maybe twenty force close reports. Is this something I can't avoid, maybe a problem with the phones memory, etc. or is there something I can do that I haven't thought of yet?

About signpost, and then went back to Twitter4J with which I have created my twitter applications when OAuth wasn't necessary. whether I should use signpost or Twitter4J's method of OAuth authentication. I have read that Twitter4J itself uses signpost for OAuth, still am not sure about the choice that I should make.

I'm developing an application which will use magnetometer data for interaction, by moving a magnet towards and away from the phone. This works fine (enough), but it seems like when I move the magnet too close to the phone, a noticeable lag occurs, and these messages are being spit out to the log:
CODE:..........
This can be also demonstrated for example in the app "Compass 3D" which is available on Market. It is enough to move a headphone in direct contact with the phone, it will produce a lag for at least 4-500 msec, and the messages above printed to Logcat. This is on my HTC Hero.

I recently got the Nexus One Update which provides amongst other things - pinch gestures.
One other unlucky surprise I got is that the app I am writing behaves differently. When I call finish() my activity's onDestroy() should be getting called. On 1.5, 1.6, 2.0 and 2.1 (before the nexus update) this works fine, but on 2.1 with the Nexus One it just doesn't call onDestroy. I have a button on one of the activity pages that when you click it, it is supposed to "finish" the activity and I verified it's calling finish(), but onDestroy() never gets called.

For one of my clients they want to redirect customers who are viewing their mobile site from their android to the android market. The url is something like http://market.android.com/search?q=com.company_name , which when clicked on as a link functions correctly but if done as a redirect via php header('location : http://market.android.com/search?q=com.company_name'); will resolve to 404 page not found.
From a pc the link will never resolved, it will only work from an Android phone and only when the link is clicked on via an a href.
Summary
a href='http://market.android.com/search?q=com.company_name' - Works when clicked
header('location: http://market.android.com/search?q=com.company_name'); - Does not work: 404 error

I get this error on my Android emulator: Sorry The application has stopped unexpectedly. Please try again. [Force Close]
I think the code that is creating the error is this: HttpClient client = new HttpClient();
I have imported the following from JARS:

So I have 2 reports now of my app causing a crash/reboot cycle the user can't always break from. I cannot reproduce this on my phone, and I am wondering what might be causing something like this? Would running out of memory or something cause this? Because I can't reproduce it, I can't look at the logs or anything.
Has anyone experiences anything similar? For reference, my app runs a foreground service which utilizes the AlarmManager. It starts automatically on boot_completed (which is probably why the cycle happens). One of the users who reported this, said it only happened when they plugged their phone into a PC.

I have created some aidl files for IPC in my Android project.
They compile and run file however in the generated .java files I am getting warnings of un-used imports as follows:
The import android.os.Binder is never used EngineInterface.java/gen/com//phone/engine line 10 Java Problem
Now I presume that they are there for a reason and since the generated file is not supposed to be modified that adding a suppress warning is not a good idea?
So how do I get rid of the warnings? I know they can be left and it doesn't affect the running of the project but I would like a clean as possible project so if its at all possible to remove this errors I would like to know how to do it.

I'm trying to update part of a VBO with a call to glBufferSubData(). When I update from the start (0) of my existing shadow buffer, there is no problem, as the buffer starts reading from 0. The following will read 0 to y from the buffer and place it at 0 to y in the VBO: gl.glBufferSubData(GL11.GL_ARRAY_BUFFER, 0, y, mPositionBuffer);
However, if I want to update a portion of the VBO (not from 0) I run into a problem; The following doesn't work, since it will write the values from the start of the buffer (0 to y) into position x to x+y of the VBO:........................

Re-wording per previous request... I am dynamically adding TableLayouts at runtime. A view rundown looks like this... LinearLayout->ScrollView->TableLayout->Loop creating TableLayouts and TableRows at runtime. So basically I am looping and adding the following:
CODE:.........
Now everything gets added correctly, looks correct and scrolls correctly. However I am attempting to create an onTouch event which changes the background on the touched dynamically created TableLayout. Inside the onTouch for each dynamically created TableLayout I have a onTouch event that when called does the following:
CODE:..................
Whenever it calls the setBackgroundColor it messes up the alignment of every one of the dynamically created TableLayouts and makes them look like this:
LeftMiddleRight
Bottom
The entire code follows. I hope this is clear now.
CODE:.............
I have tried everything I can think of to keep it from doing this but so far I am unable to explain why or how to correct it. As long as I do not call the setBackgroundColor inside the onTouch everything scrolls and aligns as expected.

In looking at some performance issues for a game I'm developing I came across some interesting facts. Although I've minimised GC caused by my app, other apps can still cause one. Also, during framerate drops in my game, I've noticed things like the weather service, email checked, etc. going nuts in the background. (This is on Android 1.6).
I don't really want to block incoming calls, i.e. go into flight mode, before the game starts. I think it's important for the game to be interrupted if there's an incoming call. However, while playing, I don't think people care about weather updates, email updates, texts, etc.
Is there an interface that will let me control what is "active" in the background and what should be "suspended"?

I have modified a sample app, and it works fine. When I rename the package though, it force closes. I have modified the package name in all the .Java files, as well as the manifest, in addition to the physical directory structure. I've even tried to create a project from scratch and copy the relevant code in. Any ideas what could be causing this? Am I missing something?

I'm trying to get a query that returns rows only with a specified name, and sort descending by week (integer).
Everytime I try and run it it gives me a FC and logcat says
CODE:..........
It says that there is no such column, which doesn't make sense because it should be looking at the names in the row and returning the ones that match. Also if I put KEY_NAME + "=" + name as null, it says that there is no such column WeekDESC which doesn't make sense either cause it is just supposed to be sorting by an integer. I have gotten this code working before, but I misplaced it and can't seem to get it working again...

Right basically you can find the UK T mobile internet settings on the T mobile website. On the Speed Test app, the highest speeds I get are 1.8m/bs downloads and around 500kpbs upload. However, those were at off peak times at night etc (probably when nobody is using the net).Generally I get anything from 0.3 m/bs to 0.9 m/bs though. Lately I've been experiencing some inconsistent internet speeds and reconnection attempts so for I've gone back to the default settings. Tbh though I'm not sure if it makes much difference.

I'm running into some issues with input events and garbage collection, or more precisely object allocation. I am creating a game and have pretty much got my head around the OpenGL environment. I've digested all the relevant material I could find regarding performance, memory allocation etc (and watched the excellent presentation by Chris Pruett - http://code.google.com/events/io/2009/sessions/WritingRealTimeGamesAn...). I've pretty much eliminated any object allocations after initial setup from my game (which is still in its infancy), but I'm still getting a bunch of GC calls, like this:...........................
