Android :: Make Precise Handling Of Pan And Zoom Finishing?
Aug 25, 2010
I am trying to write an application that will dynamically load data to map while user pans or zooms it.
So I need to track when map finished to change its view state (stops panning or zooming) and then load a new portion of data for creating markers. But in fact Google Maps API doesn't have any events to handle this.
There are some methods like creating empty overlay to control onTouch events and so on, but map panning could last long after user finished his touch (cause GMaps use some kind of inertion to make pan smoother).
I've tried to subclass MapView but its draw() method is final thus cannot be overriden.
Any ideas how to make precise handling of pan and zoom finishing?

I just wanted to know if there is some kind of class to use the multitouch features of android 2.1. Specifically I am trying to implement pinch-zoom and was wondering if I always have to measure the distance between two touch events and calculate the zoom level on my own?

I have an image displayed in a view. I want to make some translucent control over that image, just like the zoom control on the built-in 'Pictures' application, or the 'Play' button on any youtube video.
What is the general practice to achieve this kind of effect?

Is there a way to make text refit the screen when pinching to zoom like the stock browser? I like this browser its really cool, but if I have to scroll all the time then I'm going to uninstall it.

So the cable advertised that comes with this phone is a micro - USB cable. I went and ordered four cables as spares (2 for the cars and an 1 for each of our work). These cables have not yet arrived so I have not tried them yet. This is what I ordered:
Amazon.com: RiteAV - USB A to Micro-B Cable 6 ft.: RiteAV: Electronics
However, this morning I forgot my cable that came with the phone at home so I asked around if anyone had one so I could charge my phone. 4 people gave me cables to try that were micro - USB cables. They *look* like the cable that came with the phone but none of them will insert into the phone. So - now I have doubts that what I ordered will work with this phone.
1) Can anyone tell me if they think the above cables will work?
2) Can anyone tell me if there is a more precise description of the phone cables type?
3) Can anyone point me to a source of 6 foot long cables that will work with this phone?

Is there any way to do better text entry? I have the Motorola Droid, and correcting mistakes is absolutely terrible. Trying to get the cursor at the exact point where you want to make an edit is virtually impossible without multiple tries. Isn't there an app that allows for something like the magnifying glass on the iPhone?

Let's say you have a TabActivity with activities A1, A2, A3, and A4. When you click on the different tabs, no matter how many times you navigate between them, when you press the back key you leave the entire tab group, instead of navigating to a previous tab. My problem is, I am not using an actual TabActivity.
Does anyone know how to specify to Android that I'd like to mimic that behavior with a group of activities? The classic solution (that I know of) would to simply finish() the activity as you navigate away from it. That clears the stack, so that when you went from A1 and then to A2, and pressed back, you don't go back to A1.
The problem with using finish() is that I don't want the activity removed from memory. These activities load data from the network, so unless the data was cached, it would need to be reloaded on every navigation which would not be a great user experience.
I was looking at the flags which you can specify how to change this behavior: http://developer.android.com/guide/topics/fundamentals.html#acttask I tried using these: intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); But no matter what, when I go from A1 to A2 and press back, I always get back to A1.
In trying to clear the navigation stack without using finish()?

Hopefully the title wasn't to confusing but what I meant was the following:
Lets say activity A starts activity B by calling:
Intent myIntent = new Intent(Activity_A.this, Activity_B.class);
Activity_A.this.startActivity(myIntent);
Could I save/free up some memory by finishing Activity_A after Activity_B is begun (if thats even possible). Maybe through the following:
Intent myIntent = new Intent(Activity_A.this, Activity_B.class);
Activity_A.this.startActivity(myIntent);
Activity_A.finish();
Or would Acitivty_A call startActivity() and wait for Activity_B to finish before it called finish()?
The idea would then be that when the users end with Activity_B, it would just restart Acitivity_A (and finish itself in a similar fashion)? Would this create too much overhead? Thanks for any answers and I apologize if the formatting of this post isn't correct.

I read somewhere not to exception handle when developing in Android, is that true?
If one does need to exception handle are there any logging tools for 2.1 and above?
If shouldn't exception handle, why is it not recommended to at least use the below?
try {body-code} catch (exception-classname variable-name) {handler-code}

I'm using a PostMethod, and wondering what try/except handling I should use.
The exception handling here seems to work okay in most scenarios, but is there anything I might be missing? In particular, I'm wondering whether this handles the network connection going down midway through the upload.

From the documentation regarding the android:configChanges='orientation' attribute of the activity tag in the manifest:
Using this attribute should be avoided and used only as a last-resort. Please read Handling Runtime Changes for more information about how to properly handle a restart due to a configuration change.
Why does it say this?
In the case of threads and networking requests via a service API library, a request could be made with a reference to the original Activity, and then an orientation change could occur, leaving the thread pointing to the old Activity.
While this can be fixed, it's tedious and ugly compared to just handling the configuration changes yourself.
Why should it be avoided?
I guess I should also ask: would this be an acceptable reason for doing the orientation configuration changes yourself?

I'm trying to do is draw circles around two points that are being touched, and as the fingers drag along on the screen, have these circles follow each finger.
However, I'm getting some weird behavior that I can't figure out. So when I place two fingers on the screen I get my circles no problem. When I drag around with the two fingers everything works like I want it. However, if I lift the first finger, everything stops redrawing, and the second finger that is still on the screen stops being tracked. If I place the first finger back on, everything behaves good again. I figure I must be handling the two fingers poorly.
Also, if I have two fingers on the screen, and I lift and touch the second finger, everything behaves well. It's only in the case where I have two fingers and I lift the first one do I see a problem.

I know how to use handlers to update UI elements such as progress bars toasts etc. The problem I am having is when the context goes away such as the user pressing the back button or the Activity finishing for some reason. This causes my application to crash often. I tried using
getApplicationContext()
(Thinking that this would be available throughout my entire application) but this did not work, ever - instead my application crashed! I put try catch blocks around all UI update code, this works but is it necessary? What is the bast way to handle this?

I have some required try/catch statements in my application that in my testing never get called. I have sent them up with:
Log.e("messaage", e.toString());
For my debugging and now that I'm ready to release I am not sure if I should take that out or not. I see in android market you can get error/crash reports and while I do not expect my app to catch any errors, I would like to know if that happens and wondering if I need specific syntax for that. My question is what should I do in the catch statement for these errors? I'm already handling the error from a user standpoint...
