Android :: How To Code An App For G1?
Dec 15, 2008
Could it be at all possible to code an app for the G1 that would allow you to say, slightly jerk the phone to the left or right, and that gesture would act as a phone shortcut? Since the phone is equipped with an accelerometer, it seems like it could be possible to have it behave a certain way, depending on certain movements. So say I wanted to start writing a SMS message. Without even having to touch the screen, or any of the buttons, I simply just jerk the phone slightly to the right (or any sort of gesture), and then up comes the compose SMS message menu.

In an effort to reduce duplication, I have my app's workspace split into 3 projects:
Main (A library project, where all of the common code lives)
Free (To make the free version)
Paid (To make the paid version)
Behavior in the free version and the paid version must differ sometimes. How can I "call into" the final projects from the library project? Here is some sample psuedo-code to illustrate my question: Code...

I'm looking for a Bar Code app that not only does the typical scan and search features, but also saves Key Fob bar codes so I don't have to carry a key ring full of them for when I'm shopping at the grocery store etc. Is there one app that does both, or do I have to work with two?

I'm developing an application that must handle multitouch. Basically I want single touch for rotating ( this is no problem ). And multitouch for scrolling.
I have the basic code in, but I'm having problems when the shift from single to multitouch, and vice verca, occur. Basically the movement will jolt because the median position of the multitouch ( two fingers ) and the absolute position of the single finger are at a distance. So if I have two fingers on the screen, they make up a median position, and then lift one finger, it would be like a quick movement from that median position to the absolute single finger position. This will be the movement that I don't want.
This is my code:
CODE:........
The onTouchDown function of the camera just sets the first value of the touch move. That's why I also use it in the up movement to set a new begin value for the single touch movement when coming from a multitouch.

Here I update my world to include the canvas size. world.getViewPort().updateViewPortSize(width,height); Is there a better way to do this? Is there a way that I can automatically update my world object without having to manually call it in the setSurfaceSize method but instead call it from My world class? My guess is that I can use some sort of callback, but I don't understand them!
/* Callback invoked when the surface dimensions change. */
public void setSurfaceSize(int width, int height) {
// synchronized to make sure these all change atomically
synchronized (mSurfaceHolder) {
mCanvasWidth = width;
mCanvasHeight = height;
world.getViewPort().updateViewPortSize(width,height); }

Im starting my first Android project so im still kind of n00b and not sure about how to organize some things to have a clean code :P
I have my first screen with a spinner and a button. When you click the button i catch the spinner selection and the app will move to a new screen (Depending on the spinner selection).
So now, i have 2 more .xml for the layout of the new screens, but i dont know if i must continue coding in the same Activitie/.java file, or if i should make a new Activitie and in that case, if i should create this new Activitie into another .java file os stay using the same..
Im not sure if i explained myself right xD. Anyway, if anyone need more info, just tell me and i will try to make it better.

I am developing in Eclipse with Android plugin. I am trying to execute the following J2SE code on Android. It is being compiled without errors as I have imported the JRE library in the android project. In the Configure Build Path option I have imported JRE System Library and in Order and Export option I have also exported this JRE System Library.
But when it runs in emulator it gives the exception and failed to run. I think the jar files of JRE are not actually exported to Android emulator platform. If so, can anybody tell me how to export the jar files to Android emulator platform.
