I'd like to start creating Android apps but I don't like Java. I read that scala can be used to do it. Are there another option?(Clojure?) I'm a Python/Django developer so it would be great to learn a pretty different language.

I want to create a java.util.map in android from a resource. I want to do this because I have a lot of entries to populate into the java.util.map and I want to store the values in the res folder of the project in xml format.
Is there an effecient way to do this in android? My map will have around 2500 entries so I want to do this as effeciently as possible and I don't want to hard code them...
When I make a new project the .java file is not generated. I can run the project, but it does not run in the emulator or anything. It did use to work before then it stop working. I tried deleting the folder and all project files. After that I reinstalled everything but I am still having problems.

View 4 Replies View RelatedI need a very simple menu which probably contains only one or two items: settings/options, where pressing one of them should show some customer defined parameters (is it called dialog), e.g., number of results shown. Is there any good tutorial on creating such kind of menus? I've looked at the "notepad" example in android, it doesn't really help.

View 2 Replies View RelatedI know Java apps can be run in Android. But what I want to know is this: I have a perfectly normal Java app and I want to port it to an android platform. What changes would I need to do to my app in terms of GUI and other code to make it usable in Android? I know Android uses XML file to control the look and feel of its app. So would I need to change my GUI completely? I just want to know the general overview of how porting may be done. If anyone could point me to right resources, that would be great. Also, for your info I'm a newbie to developing android app.
View 3 Replies View RelatedIn an Android app I have a utility class that I use to parse strings for 2 regEx's. I compile the 2 patterns in a static initializer so they only get compiled once, then activities can use the parsing methods statically.
This works fine except that the first time the class is accessed and loaded, and the static initializer compiles the pattern, the UI hangs for close to a MINUTE while it compiles the pattern! After the first time, it flies on all subsequent calls to parseString().
My regEx that I am using is rather large - 847 characters, but in a normal java webapp this is lightning fast. I am testing this so far only in the emulator with a 1.5 AVD.
Could this just be an emulator issue or is there some other reason that this pattern is taking so long to compile?

View 6 Replies View RelatedI am trying to develop an app to supplement the built-in music player. I've used git to download the com.android.music package and looked around at its code. I can launch the music player by copying some of its code and launching activities with intents.
Now what I need to do is get a handle to its current view. In the MusicUtils.java file, I see a line that says
View nowPlayingView = a.findViewById(R.id.nowplaying);
I'd like to do the same thing. Only I don't have access to the R.java file, so I can't write e.g. R.id.nowplaying. How do I do this? How do I reference the music players R.java? I do know the R.java stuff is declared public so that shouldn't be a problem. Right?
Is it even possible? I saw this related question and am now wondering: http://stackoverflow.com/questions/2437271/how-to-load-com-android-music-code-into-eclipse-and-compile

Or is it just the same to jump right in on App development and learn on the fly?
View 12 Replies View RelatedI'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 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've had 4-5 apps so far do this to me, and every once in a while another app does the same - instead of displaying its proper name, like ChompSMS or wpToGo, the name would switch to the Java version, such as com.p1.chompsms or com.roundhill.androidWP.wpAndroid.
The name change occurs globally - in the app list, widget names, even the displayed name when I start the app. The only place where the names stay OK is the Market.
These changes don't happen after an update - just randomly but once they happen, they stay.
Some other apps include VoiceCallerID and Mystique Chapter 1.

View 2 Replies View RelatedLet's say I randomly generate a number 0 to 100. Where 0 is really cold and 100 is red hot. Wen the number hits, it would show an image bar (kind of like a % finished bar) that shows in the image what # you hit.
So it would kind of be like a progress bar from 0 to 100, and whatever # they hit it shows in the image of the bar in an imageview?
