I'm new to Android and Java programming and I've manage to create a simple paint program, but how do I add a zoom feature? Right now I'm just extending the View class and using the "on Draw()" method. Do I have to use a Drawable to be able to add zooming functionality? I'm not really understanding the differences between the two. If I am way off base then please point me to a good tutorial on paint/zooming.

View 1 Replies View RelatedI have a simple activity program in android. Basically the class just extends Activity.
But when I start it I get a ClassCastException in the constructor of my class. I don't even have a constructor defined, so it must be in the constructor of the superclass which is Activity. Unfortunately the debugger doesn't give any detailed information on what class it is trying to cast. Here is the stacktrace:
Thread [<1> main] (Suspended (exception RuntimeException))
ActivityThread$PackageInfo.makeApplication(boolean, Instrumentation) line: 649
ActivityThread.handleBindApplication(ActivityThread$AppBindData) line: 4232

And when I look into this runtimeexception I get:

The only code is:

Could someone please suggest me a good/efficient way to communicate with the server. I could think of two options 1) Use http post methods to send data to a php script at the server which would later call the google api's written in another java program (jar)or use php to use google api's (if its possible) to find nearby restaurants and send the list back to client. 2) Use simple java socket programming. The server has a jar file that supports multi threading and it does the job of finding restaurants and sending the list.

View 1 Replies View RelatedI have to create a program using accelerometers. I have written these pieces of code in order to start recording the accelerometer data when you push start, stopping when you press stop and then saving that in a file called data1.csv and so on (data2,3 4 etc). The reason I want to do this is so that I can look at the data for a given gesture and analyse it using graphs and other simple methods.
The issue I'm having is this program just makes random empty files - doesnt seem to log the data. It does make each file though, so that's nice

package com.test.Acceltest;
import java.util.List;
import android.app.Activity;

I am developing droid apps with eclipse (new to both) and have a basic Layout question. When using the layout tab (rather than the coding tab) in my main.xml, I am trying to create a home screen for when my app opens.
There is going to be the logo at the top center, then 3 simple buttons below, all centered. How do I go about formatting the Logo so it maintains a size relative to the person's screen size, and stays in the center?
I don't want to write sloppy code to where my program looks fine (UI wise) on my screen and is poorly formatted on other's screens. Also, is there good documentation explaining all of the Property values in the layout view?
I use a Live Wallpaper .apk called "Waterize Live" that is very cool. You can basically make any wallpaper look like it is submerged in water.Anyway, the only problem is that it only takes images that are sized perfectly to fit in "portrait" mode on your EVO. I will use larger images, but squish them to fit.I am looking for a wallpaper editing program that will take my normal EVO wallpapers are create these "portrait" sized versions for me. If no such app exists, can someone tell me the exact dimensions on EVO portrait view?
