Before I start to develop an application I really want to know that we can only use android Sdk on Android phones or can we use the android Sdk to develop other things like iPad, iPhone also etc?

View 7 Replies View RelatedI have decided to go to a smartphone on 13th June when my present contract expires. My Query is, I am in the U.K. and if I look at contracts for the iphone they normally include unlimited Wifi and 1Gb of wireless data, whereas the Desire seems to come with only 500Mb of wireless.
I would much prefer to get a Desire, but I am concerned that I could be lumbering myself with excess charges if I go over the 500Mb limit.
I have never had a phone with an Internet connection before so I'm sure that there will be a lot of playing going on at least to start with.
I have just recently downloaded 'stats' to keep a record of useage. I am finding it hopelessly unreliable in terms of texts. It makes obvious mistakes clearly evident from when I do random checks.
View 5 Replies View RelatedI just got a Hero, its really cool, but I'm worried about how much data this thing is going to eat up. I've got a 500MB limit, but I dont really know how long that will last. So heres a few questions
How do I know if the phone is accessing the internet through WiFi or not? Obviously WiFi doesnt count towards the limit, so I want to know that I'm using it as often as possible.
Do widgets on the home page count towards your data limit? I've got a weather widget, facebook, bbc news, email, all getting their info from the internet. Is this going to be raking up the MBs while the phone is just sat in my pocket?
Is there a number I can ring to see how much data I've used? I'm with Orange. A number to call to check my texts and minutes would be helpful, too.
does anyone know an easyway to get straight to the current useage details from 3 in your account other than clicking away at several screens to get into it.Is there a widget? or similar.

View 1 Replies View RelatedI have an EditText field and a button. My aim is to let user enter text info to the EditText or click the button to launch a dialog to select some checkbox and radio button which it will perform some computation and return a value to display at the EditText field.
I can't seems to get the value to display at the EditText field after the dialog dismiss. I did try a toast to display the value and it is ok. I *think* the view was not refresh to display the text in the EditText field.

Is it possible to use AdapterView with text fields in android?
My query returns a set of values and for each I want to place that within a textfield, so that the user may edit the value.
Also, I want to click a button to create a new empty field, so that I may insert a new entry.
If you know of good example, then please let me know!
I would prefer to use XML to define ui and I found this informations:
"In this case we create a new id called text1. The + after the @ in the id string indicates that the id should be automatically created as a resource if it does not already exist, so we are defining text1 on the fly and then using it." Source http://developer.android.com/resources/tutorials/notepad/notepad-ex1.html
Will this + allow me to autocreate as many fields as needed? Is there a way I can generically specify the layout in XML and then create fields adhoc based on db response?
I have build a sort of split view for one of my android applications. I have made an activity which is a container of a listview and a framelayout. I use the listview for a menu and in my framelayout, I load views of different activities. I have read the source code of the TabHost for building this system.
Activities that I load in my framelayout could contain a webview.
The system work pretty well but I have a big issue. When I click on a field in a webview, the soft keyboard doesn't appear and typing on the physical keyboard has no affect.
I have made many many researches and I found nothing.
When I look at all the views in HierarchyViewer, why there are multiple views's 'hasFocus' is true? I am under the assumption that only 1 view can have focus at a time. If so, why there are multiple view's hasFocus be true?
View 2 Replies View RelatedI need to retain a complex object in my service, so I can reliably come back to it (it holds updates). Initially I coded it just as a class filed in my Service implementation but I'm observing that the updates object is periodically reset to null which tells me that server class itself is recreated. Can someone recommend lightweight reliable strategy to save and recreate such updates object (I can make it serializable)
View 2 Replies View RelatedIn my app I am displaying a table where the individual cells are editable text fields (i.e. EditText objects). I am currently struggling calculating appropriate widths for these.
If I set the width to be as many "Ems" as the displayed text has characters, my fields are much to wide by about a factor of 2 and the table looks ugly and wastes lots of precious screen space. Setting the width in "Ems" is essentially like assuming the worst case, i.e. the width of a string under the assumption that it contains only the broadest characters in a font, usually 'M' (hence the name of the method), 'm', 'W', or '_'). But on average strings contain narrower characters and so most of these fields are half empty and much too wide for their actual content. I am thus desperately seeking a way to calculate a better fitting width, not that worst case width.
The "normal" way to do this in Java (in AWT or Swing at least) is to asks a widget's current Font (actually a Font's FontMetrics), to calculate and return the width that will be necessary to display a given string in pixels. But how does one obtain a TextView's Font? I haven't found any method to obtain a (Text)View's font and/or calculate a more appropriate width given the actual content of a cell's text string. How does one do that in Android?

View 5 Replies View RelatedDoes anyone know if there is standard way to get error reports from android applications running on other people's android devices? E.g. I release an android app and it goes out there. I'd love for any error to trigger an apology screen that invited the user to input a description of what happened, and then have that data along with program state and stack trace sent back to me.
View 4 Replies View RelatedI'm working on an application that will randomly point an arrow in a direction, and have that arrow maintain it's direction if the device is moved. All I want to do it get the magnetic field readings as degrees and I can do it from there. The problem I'm having is getting the magnetic field readings. I can't find any tutorials on it and the API demo on google's dev site uses deprecated code (figures, google's sample code is never n00b friendly).
At this point I've got this together but I don't know what I'm missing, all the examples I can find are using SensorListener which has onSensorChanged(int sensor, float[] values) but SensorEventListener does not support "float[] values"
