View 1 RepliesI am relatively new to android but a very big fan. I'm not a stranger to development on handheld devices, since I have some experience with Symbian OS, both 3rd and 5th edition, using C++. Implicitly I prefer development using this language, so I was a little disappointed when I heard that the preferred API for Android is in Java, though the core of Android is linux.
I read in a book that at least some parts of the Java API for android is just a wrapper for C/C++ frameworks. My question to you:
Would it be possible to develop applications in C++ without going through the Java wrapper? As far as I know, the NDK does not provide support for all the features within Android ( for example SQLite, though it's heart is not java ).
I believe it is not impossible ( I've seen some demos of early stages of Qt ported on Android ), but I'm not sure how to approach this. Would these applications be installable via an apk?
Besides making an HTML5 app (which may very well be the answer to this question), are there any other languages I can develop in for android besides Java?
View 4 Replies View Relatedhow to develop android applications. Right now I am trying to write a very simple app that calculates miles per gallon. i have wrote two versions in regular JAVA but after the past few day I just have gotten stuck trying to teach myself how i can "port" it over to work on an android phone. This one is just works within the compiler
Code:
import java.util.Scanner;
public class Mpg
{
public static void main(String [] args)
{
[code]...
I'm trying to get a simple app set up like the 2nd version, but I'm having trouble setting up the boxes for user input and re displaying it once calculated.
As I am very pissed off of using the emulator to develop any Java class, I thought of setting up a project in Eclipse and instead of the usual JRE I linked to the Android.jar (version 2.1) that usually the Android projects link to. I don't mean to use this to develop Layouts or other specific platform things, I was just trying to create a class that uses HttpClient.
It miserably crashes like this.
CODE:.............
I mean I'd like to develop libraries (and test them) so that when I go to the emulator I don't have to deal with them. Is there a good way to do this? This seems not to work for some reason.
I'm really new with this thing of "Android development" and I was really excited when I found Appcelerator Titanium, but now I got the big surprise, it doesn't work on my computer. What other alternatives are there for Android development specially if they include HTML, JavaScript and CSS for creating such applications?

Will a developer's account be terminated if he travels to an "invalid" country and logs on? I understand that he cannot upload chargable applications from certain countries. But why close his account? Some people are travelling and have half their family in one country and the other half in the USA.

View 2 Replies View RelatedI'm a beginner android developer and thinking about making a decently big game. I know that Flash air is only available to android 2.2 and future releases, but should I still make the game using Flash? Using Java would imo be so much more difficult and time consuming, but I suppose all android versions would be able to run it. Also, how efficient can android 2.2 run Flash Air? Can a game made in Flash Air run almost as fast as the game made with Java?

(ii)If not then what exactly we mean when we say the above statement? Is there any web link to which I can refer to?

View 5 Replies View RelatedIf anybody is creating multi-touch apps for Android, you may have noticed the MotionEvent class is getting more and more complicated over time. Additionally you may have discovered your code has different quirky behavior on different devices (e.g. on Synaptics devices, touch-down / touch-up can cause sudden jumps in pointer position before the down/up event is received).
I have written a class to simplify the process of writing multi-touch applications for Android, and just updated it to Android 2.2 (and to handle 3+ touch points on true 2D multi-touch sensors, as present on the HTC Incredible and HTC EVO 4G), and moved the project to Google Code hosting:
http://code.google.com/p/android-multitouch-controller/
There are numerous advantages to using this controller over trying to reinvent the wheel yourself, including simplicity and automatic device- space / object-space coordinate conversion for pinch-zoom. This also correctly centers the zoom of a pinch operation on the center of the pinch rather than the center of the screen, and supports simultaneous pinch-and-drag for more realistic pinching.

View 2 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 am very interesting in Android.It very new to me,so I want to know about it.
