Android :: Converting XML Into Java In Android
Aug 11, 2010
In my new project I retrieve an XML file from a server. I want to convert this into Java objects.Now, clearly searching on this brings up a lot of solutions and topics, but some of them don't seem to be fully Android compatible. Also, some are over complex, with automatic class creation from annotations. I prefer to write my own classes in this case.What technology would you recommend I look at to achieve this in Android?

Ive inherited some code which started out as an Android project but really is just an API to be used by other applications. Hence, the 'build' process usually just produces a JAR file. The problem I am having is that I get errors from the Android build tools in my console which seem to fire everytime I make a change to some files.

I would like to convert a Bitmap to a grayscale array of bytes (one byte per pixel). At the same time I want to just crop at section from the middle. Having looked though the various api's it is not clear to me what the best way would be.
1) What is ALPHA_8? is that grayscale? I have a feeling that the grayscale effect should be done via some "saturation" on the paint object, right?
2) once I have the Bitmap in grayscale and the right size, what is the best way to get that to a byte[] of pixels (one byte per pixel)?

I have a JSON Object with a latitude and longitude String on which I get the values doing this: String latitude = picInfo.getString("latitude"); String longitude = picInfo.getString("longitude");Then I convert them to floats like this: float latInt = Float.valueOf(latitude).floatValue(); float longInt = Float.valueOf(longitude).floatValue();And place them on a GeoPoint like this: GeoPoint X = new GeoPoint((int) (latInt*1E6),(int) (longInt*1E6) ); Debugging this values I can see JAVA approximates the values, is there anyway to keep them exactly the same?

Is it possible to convert a Canvas to Drawable?I may be really off in my solution, so if you have a better suggestion, please do tell me. This is what I'm trying to do.I'm trying to create a custom RadioButton. to set different states of the radio button, I need to use this parameter and one of the parameter to addState is Drawable. I know I can easily provide an image file and use it as a Drawable, but I want to do some image manipulation to the image before using it.There is a tutorial in ApiDemo called AlphaBitmap. It uses the onDraw method of a View to change a PNG file to full red and draw something with a gradient. So I customized it to shade an icon with gradient. So the problem now is that this is a View, and the View works perfectly fine if I add this View to the main view. But i want to convert this View to Drawable so I can use it as one of the parameter in addState. What I really want to achieve is to have different colour shades for different state of the RadioButton without providing different images to do so.

Is there a way to convert milliseconds to minutes using java.util.concurrent.TimeUnit?
This answer seems to suggest that you can use a TimeUnit.MILLISECONDS.toMinutes() method, and the documentation suggests that you could use the TimeUnit.MILLISECONDS.convert() method with TimeUnit.MINUTES - the problem is that neither TimeUnit.MINUTES or TimeUnit.MILLISECONDS.toMinutes() seem to actually exist.

Got a T-mobile pulse with unlimited txt's and data.
When i type a txt message, as soon as i hit 4 txt,s in length a message flags us saying 'converting message to mms'. Which it promptly does. If i send the message it does indeed send it as an mms. Anything under 4 in length is sent as a txt message
I spoke to T-mobile and they said update software to fix it. Which i did. And it did not fix it.
Phoned them back and they did not have a clue.
Not being able to send long text messages without being charged mms service rate.

I'm having some problems porting a Java application to work in Android platform. I detected an incompatibility problem between java sun and Adroid sdk in java.lang.Class. I oberved that: public Field[] getFields() Returns an array containing Field objects describing all fields which are defined. That's array is sorted as attributes are declared in the main Class in sun jdk. For example, next Class is defined as: public class Example { public boolean stop; public int atr1; public String name; ....
}

I am working on an application that downloads images from a url. The problem is that only some images are being correctly downloaded and others are not. First off, here is the problem code:
public Bitmap downloadImage(String url) {
HttpClient client = new DefaultHttpClient();
HttpResponse response = null;
try {.......................................
So what I have is a method that takes the url as a string argument and then downloads the image, converts the HttpResponse stream to a bitmap by means of the BitmapFactory.decodeStream method, and returns it. The problem is that when I am on a slow network connection (almost always 3G rather than Wi-Fi) some images are converted to null--not all of them, only some of them. Using a Wi-Fi connection works perfectly; all the images are downloaded and converted properly. Does anyone know why this is happening? Or better, how can I fix this? How would I even go about testing to determine the problem?

Does anyone know how to convert the accelerometer readings from g's to degrees?For example, if I want to use the x-axis readings and measure the tilt of the phone, flat would be 0g = 0 degrees and a 90 degree tilt to the right would be 1g (9.80665 m/sec^2).I can't come up with a formula for say 20 degrees or 45 degrees. Any help would be greatly appreciated.

Hey Guys, I just replaced my blackberry 8310 for an incredible (wow). Is there a way I can move the data over? I did have google sync for my calender installed and working; but since I mainly work on office 2010 beta, gsync doesnt work. So, i hadent noticed the gsync wasnt syncing with my calender. That being said is there a known way to get the data over? Phone service is terminated so it has to be done tehtering to the PC somehow..I was able to get contacts no problems there as I had them in many locations, but would like the notes also.

I'm having my first stumbling steps with android and are trying to modify an existing notepad example from Android dev. I have a database with an existing column named CREATED_DATE (of the note) but the data for that column is presented as System.currentTimeMillis(). This is all good and probably in line with conventions since it's created by the developers.
But my problem is that I want to present the date in a ListView using the format "30 sep". My problem, how do I convert the data to that format before presenting it in the ListView? Right now I'm using this kind of adapter:
CODE:...........
Now, I've figured out how to convert currentTimeMillis() to todays date but how can I convert the data coming from the cursor before I toss it into the adapter?

The Canvas class does not take Shape as a parameter for any of its methods. There is no drawShape or clipShape, etc... So, I need to use Path instead. Does android sdk expose any way to convert Shape to Path or Path to shape? I haven't been able to find relationship any between the 2 classes...?

I do an import of the full package name / java file, and if I do a <classname>.<method>, SOMETIMES I can get it to access - other times I get a lot of can't use a static in a non static bunch of talk. I'll admit I'm new to Java, so what do I need to do? Call a class instance first, then call my methods? I'm rather confused by this, as I want to put all of my 'functions' into a FunctionsList.java file, and all of my main Activity (UI) into a MyActivity.java file.
For example:
<MyActivity.java>
import com.example.FunctionsList;
private class MyActivity extends Activity {
FunctionsList.function();
}
9/10 times I get that static/non-static error. If I put all of my functions into MyActivity.java, I have zero problems!

I have an app I am working on that does some math on a few variables and outputs the answer. Well that's the plan anyway. Being a total n00b at Android & Java I am not sure of a couple of things.1) I have created text fields in the layout file for user to enter values. Instead of text fields should I use numerical value fields, if such a thing exists? 2) How can you convert from a text field to a numerical value and back again?
