I was wondering if there was any way (I'm somewhat a newbie at Java) to get the MapBounds of a Google MapView on Android.
Just to clarify, here's what I'd like to do.
Calculate the maximum and minimum long and lat whenever the map is moved, or zoomed and display those values in a Toast.
Is there any possible way to do this - or am I in over my head?

Before I updated to android 2.2 and updated to latest Googlemaps the navigation was perfect. It calculated the route in seconds and was a joy to use. Since the updates, it is taking ages to calculate route, so long in fact that I exit the programme and start again, and then I just give up and dig out my atlas.

I can do this very easily using my Macbook Pro by firing up Google Maps in Chrome browser.(or any browser)
However, I just can't figure out how to do this using the Google Maps app on my Samsung Galaxy Note 3. Sure, I can use use a browser to do this, but I want to do it inside the Google Maps app for Android.

I wanted to create an gallery with images.The images within the gallery should be zoomable and pannable. I could able to pinch-zoom an image but could not able to set zoom limitand prevent the image from being panned off the screen. I used the following code to zoom an image:http://code.google.com/p/4chan-image browser/source/browse/src/se/robertfoss/MultiTouch/TouchImageView.javaspec=svnd3e623ddeb6f9e97d9eba2c7aaa7c4567a3822b5&r=d3e623ddeb6f9e97d9eba2c7aaa7c4567a3822b5 First approach : I used TouchImageView to supply images to gallery, this allows me to pinch zoom but can't scroll the gallery. i.e I cant differentiate between 'single tab event' and 'tab to scroll event'
View 1 Replies View RelatedI am having some trouble working with the SQLite database. I am able to create the database, add to it, and delete from it with no problem by following the Notepad examples, but I am trying to avoid duplicates and therefore want to check to see if an entry exists already.
Below is the code I have for testing to see if a game exists. I get the correct Log message of "No Games" when there are no games, as well as the correct value for column from getColumnIndex which is proven to me by the log printout telling me that column = 1.
The error message that I receive if I don't catch the exception says "Caused by android.database.CursorIndexOutOfBoundsException: Index -1 requested, with a size of 1
Where is Index -1 being requested if my call to getColumnIndex is returning 1? Code...
The following function is giving me an out of bounds exception...
public void count(){
SQLiteDatabase db = table.getWritableDatabase();
String count = "SELECT count(*) FROM table";
Cursor mcursor = db.rawQuery(count, null);
int icount = mcursor.getInt(0);
System.out.println("NUMBER IN DB: " + icount);}
It's meant to return the number of rows in the database. Anybody know whats wrong? am I perhaps doing this task the wrong way?
On ICS I used to skip songs on Poweramp using the headset button, but since I upgraded to Jellybean, the long press goes to Voice Search on Google Now? Is there a way to disable that? I already configured on Poweramp to use the long press, gave it high priority, but google voice continues taking place and there's no options there to disable it.

Android Version: 4.2.2
Steps to reproduce the problem:
- plug in headset
- lock screen
- press headset button for several seconds
What happened:
- No reaction, Google Now / Voice Actions not launched
- Manually unlock screen
- Long press with unlocked screen correctly launches Voice Search
What you think the correct behaviour should be:
Long press of headset button should launch Google Now / Voice Actions even with locked screen. Having to dig the phone out of your pocket in order to launch Voice Actions with a headset e.g. to place a call kinda defeats the purpose of using Voice Actions in the first place.
Adding insult to injury: long press is not broadcast to other applications because of Google Now, so it can't even be put to good use e.g. as volume control.

Since I installed (might just be a coincidence but I did update Maps via the market) 2.1, Google Maps takes so long to update when showing directions. For example I'll be in one street and have walked to another and it will still show me in the previous street after 30 seconds or so later. Also I noticed today when using it, that the arrow wouldn't move and just stays in one spot but the arrow does change direction though.
I could have sworn it wasn't like this before and I could just use it like a real gps unless I've overlooked something.
Also I get the "Current location temporarily unavailable" message all the time when searching my location unless I tick the Use Wireless Networks in the Location settings of the Hero. When I had 1.5, I didn't need to do this and just used GPS satellites.
What am I doing wrong here?

We're seeking advice for our application in the Android Market, in relation to nominating a suitable minimum SDK version for the APK files published through the market. We understand that at this juncture there's no facility to provide associate multiple APK files (supporting different minimum SDK versions) within a single listing in the Market.
We have updated our existing application with new Android 1.6 API features and are keen to release it to the Market. However we're concerned about the general availability (and uptake) of version 1.6 firmware and seeking to ensure that we don't inadvertently release an updated APK should there be limited release of this firmware.
Can anyone provide an indication as to how widely the 1.6 firmware has been released? To that end, what are generally acceptable practices for supporting multiple SDK versions from within the market?

View 2 Replies View RelatedI have a TextView in a RelativeLayout which contains an integer number. The number will range between 1 and 99 - can anyone tell me how to size the TextView so that its width is always the width of the string "99" even if it only contains "1"?
I need this because the positions of the components to the right of this TextView depend on its width, so all are position depending on how many digits the TextView contains.
I don't mind if this is done in XML or code - I just want to avoid having to set the width of a TextView in pixels!

I'm looking for a way to implement a minimum value in my SeekBar and also have the option to increment decimal numbers. For example, currently my SeekBar's minimum is set to 0, but I need it to start at the value 0.2. Also, I would like to have the functionality to be able to have the user select a number from 0.2 to 10.0 at a .1 precision so they can choose the numbers 5.6 or 7.1.
Here are the style attributes for my SeekBar:

I am trying to make an app for the Android that does RMD calculations. The program, however, keeps giving 0.0.
I think that my problem lies in this code:
CODE:......................
I tried using .equals(), but it complained that I was trying to dereference the long value. Also, I am aware that java.util.Date is deprecated, but I don't want to try the other classes. From my first Android app, I figured out the "==" does not work, but I am not sure what to do here.
I have verified that the input for a balance and the birthdate values were accepted, so that is how I limited it to this particular class.
What do you usually use for your minimum sdk when compiling? Should I just compile it to 2.x since I think 1.x is already obsolete?

View 1 Replies View RelatedI need to calculate a rotation vector out of the data i get from Sensor.TYPE_ORIENTATION. The sensor data is defined like this: the values have to be recalculated to become a correct 3d position: values[0]: Azimuth, angle between the magnetic north direction and the Y axis, around the Z axis (0 to 359). 0=North, 90=East, 180=South, 270=West values[1]: Pitch, rotation around X axis (-180 to 180), with positive values when the z-axis moves toward the y-axis. values[2]: Roll, rotation around Y axis (-90 to 90), with positive values when the x-axis moves away from the z-axis need all three values like the Z axis value (from 0 to 360 degree). I tried a lot but cant figure out how to do this :/ So i bet there is a simple solution how to recall the values of sensor.TYPE_ORIENTATION to make them a 3d rotation vector, but i just dont know how to do it. If you know the answer please tell me. Code...
