I have looked at every discussion and thread I can find on getting this to work but it is not. I have a simple timer that updates a text view (mTimeTextField in the example below). The mUpdateTimeTask run method is being executed correctly (every second) but the UI/text field is not being updated.

I have an "open" animation and am using Handler.postDelayed(Runnable, delay) to trigger a "close" animation after a short delay. However, during the time between open and close, there is possibly another animation triggered by a click...my question is, how would I cancel the "close" animation in the handler?
View 1 Replies View RelatedI 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:
CODE:..............
The constructor is invoked from the main MapActivity.onResume() using
locationOverlay = MyLocationOverlay(this)
And the animate/draw is invoked by
CODE:.................
However, the run() method never seems to be invoked.
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.

I made a simple countdown timer and it works as expected when plugged in via usb for debugging but when I take it off debugging and the screen goes off either time out or power button the handler fails to fire at the end time. I have created a custom timer class that gets created from the main activity when needed, because its able to have multiple countdowns running at the same time. Am I right in thinking that the handler just gets paused when the screen goes off and if so what are my alternatives. The activity is still in the foreground and I assumed the handler would still fire if the screen goes off.
View 13 Replies View RelatedI am new to Android development and have been working on a simple demo app that needs to update a TextView a few times from an array after a button is clicked. I have read and adapted the code found here to achieve this: http://developer.android.com /resources /articles /timed-ui-updates.html
View 2 Replies View RelatedI want a widget showing a countdown for a user initiated tracking of a bus departure. I want to update the widget every minute or so, from when the user initiates the tracking to when the bus has departed (i.e. the time runs out). This widget needs to be updated more frequently than what updatePeriodMillis allows, which is every 30 seconds. I reckon about once a minute. Being new to Android programming, I can think of a few ways to do this, but I would probably end up doing it in a way that consumes way too much battery etc, so I'm looking for some insights from more experienced Android developers. How do I start the timer? How can I access the widget instance from my applications run-time? And so on.

I'm trying to write a simple toy application that updates a string every second with the current time (unformatted). With the code below, my console prints out the current time every second, but the TextView doesn't. The TextView seems to update once at the beginning of the program, but otherwise stays the same. Sometimes I'll click the button and it will change once or twice, but that's about it.
I'm not really sure what's wrong here. The timer seems to be working fine, but not the TextView. I looked for something in the TextView that might allow me to force an instance of the TextView class to update, but could not find anything (which is what I would expect, since setText() should automatically update the TextView).
my code is below. I'm using Android 2.1 (emulated).
Code:
public class HelloAndroid extends Activity {
/** Called when the activity is first created. */
@Override
[Code].....
It can no longer kill another program after setting the countdown timer. I used to use it every night to listen to music and then have it shut everything down. My understanding after talking with the developer is that Froyo has removed the ability for developers to kill programs. Supposedly with root access there is workaround, but I am not rooted. Unfortunate, it's a great app and hopefully something that will be allowed in future Android versions.
View 1 Replies View RelatedI tried the following from an activity:
@Override public void onPause() { super.onPause();
postDelayed(new Runnable() { public void run() { mTextView.setText("I am paused!"); }, 10000); }
The activity, while in the background, still executes the runnable. Is this incorrect? Should we absolutely call removeCallback() from our onPause() handler to ensure that no postDelayed() runnables execute if we get paused? Or is it necessary to do this only in onDestroy()?

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:
CODE:.............
This compiles, but when my GLSurfaceView sub-class is constructed a NoClassDefFound exception is thrown, telling me that the class com.my.package.MyGLSurfaceView$1 is not found.
Here's the log:
CODE:.............
The line 297 in MySurfaceView.java is:
private Runnable mUpdater = new Runable () { public void run () { [...] } };
I downloaded an update this morning and once my phone restarted my wi-fi wouldn't work. I had a orange branded desire which I rooted with 2.2. When I updated the desire I never had the gold card in so I know this is the problem. post a link so I can download the vanilla 2.2 with sense as when I tried this morning to click on a link on here it was asking for usernames and passwords.

with not a trace of the messages from the Runnable. So appearantly the Runnable doesn't run(), although img.post() 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?

after updating (the official update) my HTC Desire to Froyo 2.2 I cannot capture any Video (any resolution). It happens that I press the trackball and the timer (on the upper-right corner) disappears and nothing works anymore (menu, etc...), only the Home button allow me to go back to the home panel. After doing that, the battery die in a few minutes and the phone is very slow: i.e. some video camera service is still up and running and consuming battery.
View 4 Replies View RelatedSo I have stock android 2.1 installed on my phone. I haven't gotten the OTA update. I tried to manually update, but recovery mode doesn't seem like its working - I see the triangle/question mark but there is also a phone laying down right next to it. No combination of keys will get me to a menu to apply the update.zip. I tried flashing back to 2.01 and 2.0 and updating from there - but the recovery mode stayed the same. Does anyone know where to find the full Froyo stock .SBF files?

Anyone having trouble with widgets stop updating? Like my clock/calendar/weather/news/pretty much any widget i have stops updating after an hour. So i look at my clock widget two hours later and it is an hour behind. Happens to ALL my widgets.Even the quick turn on/off wifi,bt,gps and such. They just stop updating/showing animation.I have ADW launcher installed. I am wondering if it is that. I do not really want to remove it as i hate the stock 3 button interface at the bottom (why do i need a contacts and phone, just use the phone to look thru contacts, wasted space IMO) and am quite keen on keeping the 5 button.Any ideas? If i power off the phone and turn it back on it's fine again for about an hour. SOmetimes randomly thru the day it will start updating and working fine again then randomly stop again.
