Android :: Runnable Interface

Mar 24, 2010

I'm having hard times getting my GL thread (from GLSurfaceView) to trigger some code execution within the UI thread (from Activity). I tried it in every possible way (well not every, I missed at least the good one) none worked.

My idea was to get something called from the UI thread (to update some widgets) when the surface is effectively created. So I added to my onSurfaceCreated method the following call:


This compiles, but when my GLSurfaceView sub-class is constructed a NoClassDefFound exception is thrown, telling me that the class$1 is not found.

Here's the log:


The line 297 in is:

private Runnable mUpdater = new Runable () { public void run () { [...] } };

Android :: Updating UI From Runnable

Oct 3, 2009

I didn't found clear answer for why my code does not work. I assume it is because I am trying to update textview from runnable. Anybody know some workaround? Code isn't clean off course, I am happy to get that working so far as I am totally new in java.

Android :: Runnable Posted Successfully But Not Run / Fix It?

Nov 3, 2010

In an existing Android project I've encountered the following piece of code (where I inserted the debugging litter) code...

with not a trace of the messages from the Runnable. So appearantly the Runnable doesn't run(), although returns true. Pulling the ImageView in onCreate() and declaring it final doesn't help.

I'm clueless. Simply setting the bitmap directly, while blocking the UI thread, does fix things, but I want to get things right. Does anybody understand what's going on here?

(ps. this was all observed on an Android 1.6 phone and android-3 sdk)

Android : Valid Context Inside Runnable That Will Do Insert?

Nov 6, 2009

I'm trying to do an insert to a DB as a result of a user clicking on a button. I want to do the actual insert in the background, so it seems I should use a Handler to do this. The SQLite insert method takes a Context parameter. My problem is how do I get a valid Context inside the Runnable that will do the insert?

Android :: Problem Using Runnable - Handler.postDelayed For Bitmap Marker Animation

Jul 26, 2010

I want to place an animated marker showing a user's current location in an Overlay over a MapActivity. I need to be able to turn the animation on and off.

I thought this could be accomplished as follows:


The constructor is invoked from the main MapActivity.onResume() using

locationOverlay = MyLocationOverlay(this)

And the animate/draw is invoked by


However, the run() method never seems to be invoked.

Android :: How To Interface With Google Calendar?

Jun 4, 2010

I am building an app for Android 2.1 that provides notifications based on calendar events. But I'm aware there are issues with the Calendar API not being readily available / stable / whatever. What I'd like to do is somehow communicate with the user's Google Calendar to get a list of tasks every few hours, or perhaps when the calendar is updated, and then store that data locally so they don't need to have an active Internet connection at all times. Then at a particular time, the notification event would occur. Surely, someone must have determined a way to interface with Google Calendar? I'm sure there must be numerous apps and solutions available that connect to it already, and my users can use any interface they like for interacting with it, but I need to be able to read the data and store it locally.

Android :: Modifying The User Interface

Apr 29, 2009

I am looking for some answers from some of the experts here. I have a project in mind that I want to start. It is about using HTC's Touch HD phone as a device in a museum with rich media/video about the art and the artists on it. Besides the videos and animation, I also want to show some content from a web browser. Now my biggestest issue. I do not want that the museum guest who pick up the phone for the tour get to see the standard Android user interface. Is there a way to develop a new user interface that would start up directly once the phone is turned on? It should then automatically start the app with the museum infos. Later I may want to add some GPS functions and even sms and photo taking, etc....

What do you think, how flexible is Android to allow that?

Android :: Looping Through Interface Elements?

Sep 2, 2009

This is probably a very "newbie" question as I'm relatively new to the android sdk, but figured this would be good place to ask.

Say you have a layout with several textviews that all have sequential IDs (ie, tBox1, tBox2, tBox3, etc).Is it possible to reference each box in a loop? Something like:

do { iCount++; View tvBox1 = findViewById([iCount]); }

Android :: Remote Interface - Parcelables Problem

Sep 23, 2009

Been using remote interfaces for quite a while now, but the time has come to increase the amount of data i need to pass between processes. Following the Designing a Remote Interface using aidl examples/ tutorial i have had some success but have now come to a problem.

My activity binds to my service no problem, the callbacks work, but the data i send does not reach the client. My code is an extension of "Pass by value Parameters using Parcelables" from the "Designing a Remote Interface using aidl" page. The only difference is the amount of data, it has 18 int's and 3 Doubles. As you will see below, once i have entered the data into the parcel, i create my Parcelable using .createFromParcel(p) this however does not seem to work, even when my Parcelable is reading from the parcel no data gets read.

Here is my code for sending the data to the client.


Here is my Parecelable:

HTC Hero :: Stock Android Interface In VillainROM 12?

Jul 20, 2010

I have VillainROM 12 installed on my Hero and have been playing around with various themes from the standard Sense UI to things like dxtop. I do want to try out the stock Android UI which I believe is accomplished by just going into Applications>Manage Applications>HTC Sense and selecting clear defaults thus setting it to stock Android. Thing is that in my install of VillainROM 12 the "clear defaults" button is greyed out and unavailable to be pressed. Is this an intentional thing in VR12 or am I maybe going to have to re-flash in order to achieve this?

Android :: Is IPv6 Over Wifi Interface Supported In SDK?

Apr 20, 2010

I'm hearing that IPv6 is supported by android, at least over the wifi interface, but I cannot do anything with IPv6 through the SDK at all. I am running Android 2.1 on an N1. I can see that at the OS level, the wifi interface has a link local inet6 address: ufo:~ newton$ adb shell $ cat /proc/net/if_inet6 0000000000000 0000000000000000001 01 80 10 80 lo fe80000000000000022376fffe8d1e63 0c 40 20 80 eth0 although ifconfig does not show it: $ ifconfig eth0 eth0: ip mask flags [up broadcast running multicast] If in Java I call getInetAddresses on a, I only get the inet4 address. As I'd expect from the above, I cannot connect via any Java APIs to another link local IPv6 host on the same wifi lan Depending on my approach I get "socket level is invalid", a bad socket options error, host unreachable, or timeouts.

Android :: Expose Service Interface To Other Application

Aug 31, 2009

I have created a service and want to expose the interface to other applications. For one service I have done this successfuly. I just put the AIDL interface into the new project and all worked fine. Now for this service I've done the same but I get a java.lang.VerifyError when trying to use this interface. I think that the problem is that the AIDL uses a class (PolicyRole) that is only defined in the source code of the service. To compile the source that uses the interface I had to link against the code of the service but at runtime the error appears. Code...

Now my code looks like this...

As I run the program, Eclipse displays
