[android-developers] Re: Need to buy 15 Nexus One Unlocked
Thanks, a few wrote me with good suggestions. I'll contact Best Buy and find out what the unlocked price is. I have 3 N1's in use in the class right now running Cyanogen. Wireless AP only. Can't afford 15 plans. Thanks to all of you who responded or emailed with suggestions. Very helpful.

[android-developers] Need to buy 15 Nexus One Unlocked
Hello, I'm a developer and I recently got a grant approved to buy hardware for an Android developer class. I'd like to get my hands on 15 Nexus 1's. The limit listed is 10. Is there anyone I can contact? Can I get the Nexus S unlocked at Best Buy does anyone know? Thanks for any assistance.

[android-developers] Middle School Android Programming Class
Hello all, My name is Josh Beck and I teach course to advanced eighth grade students. There are 26 students in the class and right now we only have 4 development devices to work with. (Everyone else uses the emulator right now, which can be limiting.) I've qualified as a finalist in a competition sponsored by Rackspace hosting. They have opened up a public 'survey monkey' based public ballot to help determine which project will receive the funds. Getting a 1-1 development handset-student ratio in that class would be a giant leap forward for our curriculum. So, if you like the idea of helping young Android developers get their hands on development tools, please go here: http://www.surveymonkey.com/s/V22YXLW and vote. Below is a list with descriptions of all the projects who have qualified to be $10,000 grant finalists. (They are all worthy, please read the descriptions.) Thanks everyone! “IF YOU CAN DREAM IT” Finalists Krueger MS http://www.surveymonkey.com/s/V22YXLW --Classroom Video Cameras-- There is a class set of Kodak Zi8 SD cameras in the technology wing, but every classroom that wants a camera should have one to document and share lessons, highlight excellent learning and to show off student work. It will engage the audience and allow teachers to show each other the best of what is happening in their classrooms. It also will help unify team efforts and inspire better learning. Students would also be able to film and edit video pieces. Metric: more than 30 teachers sign up for cameras; good classroom videos begin making it into the combined archive and made into relevant, entertaining and educational videos; posting (videos and comments) on KMSN.ORG. --Android Programming Phones-- Students do not have enough Google development handsets to test the programs they develop. Class would like a few netbooks preinstalled with development software so that students could check them out with a development phone to work on code at home or over the weekend. We currently have 3 dev phones but would like to have 15-20 devices in the classroom. Students have the option to declare a business with the IRS, set up a merchant account with Google, set up a business bank account and have direct deposit working from the Android market to their business accounts (with parental consent). Students last year made hundreds of dollars on the apps they developed. Metric: Increase in students setting up a business and generating revenue on the market; increase in the number of students making money from their apps --“You in SA” after school club-- Students meet once a week to research, plan and organize Saturday field trips to locations around San Antonio such as universities, museums and historical markers. Students will be able to engage with areas of SA that impact them economically, socially and politically. They will discover places that will open opportunities and impact their future decisions. Families will benefit from the exposure students receive as they discover opportunities for themselves in SA. Metric: fewer office referrals, improved academic performance, improved TAKS performance --4-Part Bullying Proposal-- Bullying is a huge problem that takes away from instructional time and focus. We would like to approach it in four parts: 1) Kick off bullying awareness week with coolassemblies.com (Cary Trovanovich) and continue character education throughout the year. 2) Motivate students by engaging them in high-energy assemblies by Patrick Perez. 3) Train staff and 50 student/grade level (select leaders of the pack) in ropes training (Fusion) to teach tolerance and proactively address suicide prevention. Fusion is through Region 20. 4) Safe School Ambassadors custom designed end-of-year retreat for 70 students who are part of the behind-the-scenes anti-bullying campaign at Krueger.

Hello All, I have a series of live wallpapers out and one major sticking point I have with a certain set is that when devices switch to Landscape, the wallpaper, which in most cases is an image designed to fit the screen in portrait mode, appears off center.

[android-developers] Re: Creating Simple Serial Output:
Thanks for the response. I've got an arduino board that has serial output via 4 pins. Pin 1: ground Pin 2: transmit Pin 3: Receive Pin 4: reset I plug a usb adapter into it and that allows me to upload code to the microprocessor and monitor the output locally. To answer your question: -I'm looking to replace the arduino completely with a program running on the phone that somehow, someway generates a simple serial message 'as if' it were being transmitted via that simple pin configuration. (We're using a video overlay board that accepts serial data and creates a real time GPS text overlay for the students to watch locally and analyze later.) -Thanks for the advice. We've been using this Arduino for years now and I think it's time to replace it completely with Android. --It's a fun challenge.

[android-developers] Creating Simple Serial Output:
I've got a fairly unique situation: -I'm a teacher with a magnet school that focuses on rocketry and technology. -I've got a rocket payload that has a video overlay board which does the following: -Takes input from a camera. -Takes input from a serial data line. -Overlays the text input to the video screen in real time and saves to avi. -Right now we're using this antiquated device called an Arduino board which is cave man stuff compared to the developer phones we have on campus. (It's very educational making one work, but still old hardware.) -The Arduino processor essentially outputs data to a 'transmit' pin that can be easily hooked up to a pc serial port. (Serial Data.) -My present course of inquiry: (I'm a fairly proficient Android developer) -- -Can I write a program that outputs a simple string like this directly to the usb data cable: String aString = "abc"; --- -From there, would it be possible to purchase a usb to serial converter and grab the associated data off the correct serial pin? -I'm not an electrical engineer by any means, but I think that a serial converter would have to boost the voltage from the USB line in order to work because usb voltages are lower than what comes straight out the serial port. -Does this sound like a correct assumption? -Any advice is appreciated.

[android-developers] Re: Advice on Swipe Direction and Velocity
Actually, I'm working with openGL. So, it looks like
I'm supposed to set up a GestureListener and override
onFling to increment Y or X. Then use Y and X from there to rotate my
object and
slow it down and stop it using a math function.

Ok, I've done some reading and I have a working theory:
It's done using something this:
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
switch (keyCode)
{
case KeyEvent.KEYCODE_DPAD_DOWN:
(increment static value X by Y );
break;
{
This way a faster swipe results in a higher value?
Sound logical or am I off?

[android-developers] OpenGL Textures
Hello All,
I'm learning OpenGL on my own atm and I have a question about
texturing a surface:
I can create a simple polygon like this:
public class Square {
// Our vertices.
private FloatBuffer colorBuffer;
float[] colors = {
.5f, .5f, 0f, .2f, // vertex 0 red
0f, 1f, 0f, .2f, // vertex 1 green
0f, 0f, 1f, .2f, // vertex 2 blue
1f, 0f, 1f, .2f, // vertex 3 magenta
};
private float vertices[] = {
-.7f, .04f, -.5f, // 0, Top Left
-.7f, -.04f, -0.5f, // 1, Bottom Left
.7f, -.04f, 0.05f, // 2, Bottom Right
.7f, .04f, 0.05f, // 3, Top Right
};
private short[] indices = { 0, 1, 2, 0, 2, 3 };
Then I load all of that info into the approriate buffers and draw it
to the screen with a call to:
gl.glDrawElements(GL10.GL_TRIANGLES, indices.length,
GL10.GL_UNSIGNED_SHORT, indexBuffer);
My question:
I'm looking for a good example of how to take an image and texture it
to the surface.
(I'm looking for a good book on JOGL with examples.)
Any suggestions are appreciated.
Thanks,
Josh Beck

[android-developers] Re: Live Wallpaper --OpenGL Help/Advice.
I can see that now and I thank you for the response.
Really, your directions were very clear and your GL service
is incredible. I hope to see it incorporated in the official 2.2 API.
You deserve it, and I thank you!
Nancy, thanks also. --Your directions are what I was able
to follow in order to fix my setup. Very talented.
I'm a hack at this stuff, and the information I gleaned from this
fix was just what I needed. --Great knowledge!
(Believe it or not, I'm actually trying to teach this stuff at the 8th
grade level)
http://www.neisd.net/ComRel/News/Krueger_Smartphone_10.htm
(That's my class)
I can fire off basic intents and work with the hardware on the phone
fairly competently, but OpenGL is new. Now I can do a couple things:
1.) Play with polygons
2.) Teach the students pictured in that article to play with polygons
based
on the template I now have. They'll love it!
Thanks again!

[android-developers] Re: Live Wallpaper --OpenGL Help/Advice.
I was afraid you might say that:
I've gone through and incorporated GLWallpaperService per his
instructions, but specifically I'm getting hung up here:
--QUOTE--
In your GLEngine subclass, instantiate your Renderer, configure it and
set it using setRenderer(Renderer) and setRenderMode(int).
--/QUOTE--
(http://www.rbgrn.net/content/354-glsurfaceview-adapted-3d-live-
wallpapers)
Logcat is throwing a null pointer exception at line 79 in
GLWallpaperService.java which reads as follows:
---LOGCAT ERROR--
@Override
public void onSurfaceCreated(SurfaceHolder holder) {
Log.d(TAG, "onSurfaceCreated()");
mGLThread.surfaceCreated(holder); <--Right Here Line 79
super.onSurfaceCreated(holder);
}
---END LOGCAT ERROR---
The following class works perfectly within an Activity for me:
--BEGIN CLASS--
public class OpenGLRenderer implements Renderer {
//Should it be GLSurfaceView.Renderer? <--
private Square square;
private float angle = 45f;
public OpenGLRenderer() {
square = new Square();
//I have a square class that defines verts and
such.
}
public void onSurfaceCreated(GL10 gl, EGLConfig config) {
--Clear the screen and prep it--
}
public void onDrawFrame(GL10 gl) {
--This function draws and rotates my object--
}
public void onSurfaceChanged(GL10 gl, int width, int height) {
--The code I have here also checks out in an Activity--
}
}
---END CLASS---
-My Initial class extends GLWallpaperService --onCreate() as
follows:--
public void onCreate() {
GLSurfaceView mGLSurfaceView = new GLSurfaceView(this);
//I have a feeling this is misplaced.
}
--My subclass extends GLEngine--
class CubeEngine extends GLEngine {
private final Runnable mDrawCube = new Runnable() {
public void run() {
//Does Nothing ATM
}
};
private boolean mVisible;
CubeEngine() {
//Blank Constructor
}
@Override
public void onCreate(SurfaceHolder surfaceHolder) {
super.onCreate(surfaceHolder);
mGLSurfaceView.setRenderer(new OpenGLRenderer());
//This setRenderer is what I need help with.
// By default we don't get touch events, so enable them.
setTouchEventsEnabled(true);
}
--I don't think I need to override the
things like onSurfaceChanged here, because
I think that my OpenGLRenderer Class
handles that, or at least it should. --
Thanks for being patient with me. I'll sort it all out in time I'm
sure.
Just getting an OpenGL object to work correctly in a regular Activity
was
a giant leap!

[android-developers] Live Wallpaper --OpenGL Help/Advice.
Hello all,
I can construct an Activity that utilized OpenGL to draw a square, set
properties, and
make it rotate around a fixed point by implementing
android.opengl.GLSurfaceView,Renderer
and configuring:
public void onSurfaceCreated(GL10 gl, EGLConfig config) {}
public void onDrawFrame(GL10 gl) {}
public void onSurfaceChanged(GL10 gl, int width, int height) {}
-Separately
I can construct a live wallpaper by drawing an image (Bitmap) to a
Canvas
as specified at:
http://developer.android.com/resources/samples/CubeLiveWallpaper/index.html
My Question:
I'm trying to figure out how to create a GLSurface and draw to it
within a Live Wallpaper.
I'm all about doing research. So, any advice is appreciated.
The Simple Cube wallpaper demo Google provided was VERY helpful.
I think a lot of folks would like to see something along those except
with an OpenGL cube in mind.
--Much appreciated. I'm totally new to OpenGL.

[android-developers] Android Programming Class
Hello everyone: I teach an 8th grade programming class in San Antonio Texas. We're learning Android and I convinced the school to buy us 3 dev phones for the kids. Here's an article about what we're doing: http://www.neisd.net/ComRel/News/Krueger_Smartphone_10.htm I'd like to purchase a netbook to supplement the phones so that when the students check them out, they have an out-of-the-box programming environment within which the phones work. I've put together a donation page. My goal is to raise $350 dollars for a netbook to go along with these devices. If you can donate $1, $5, or $10 to help my class out, it would be greatly appreciated. http://www.linuxclassroom.com/donation/donate.html Thanks so much for considering it!

Apparently my home phone number, where my wife and kid are asleep at 7:30, is listed directly under my application. I'm good for customer support. I just prefer, and I would imagine google might agree with this, to take care of people over email. Does my developer number have to remain there? (The sub text next to the profile page number clearly indicated it would not be distributed to third parties.) Does anyone have any thoughts on the phone number placement?

Here is why the application wouldn't launch:
I ran the program with the phone plugged in using Eclipse->Run As-

-This ran the map activity, but only displayed a grid
because the api key is designed to be used with a signed apk.
Running directly from eclipse installs an unsigned
package.
(I figured this was the case.)
-Then, I tried to install the apk via my web server and it spit out
a signature mismatch error.
-It also said it couldn't install the app in the app directory.
It turns out that running the application via eclipse on the phone and
then trying to install the apk triggers a signature error.
(I can only assume this is because the version run directly from
eclipse has no signature and the apk has a good one.
This conflict, I think, triggers an error. --invalid signature. The O/
S assumes the first signature is the good one?)
Solution:
I found the application via the settings manager and manually
uninstalled it.
It was identified as 'mymap.' (See Manifest Above)
Once I uninstalled it, the apk installed cleanly without any conflicts
and the map appeared .
Anyway, I hope this helps someone in the future.
It's Alive!
You guys are great,
Josh

[android-developers] Re: MapActivity Problem --Debugs but won't launch from signed apk.
Hello there,
Thanks for the response.
I debug using the actual device, but you are right. It probably
treats the phone as if it were the emulator in that case.
I've followed the directions and obtained an MD5 fingerprint of my
keystore.
I used the sign-up form and passed it the fingerprint in the form of
XX:XX:XX ... etc.
The form returned an api key, which I actually use in the place of
this:
MyMapView = new MapView
(this,"MyApiKeyDerivedFromKeystoreMD5");
Logcat isn't giving me any useful information that might help me
determine the
cause.
-Questions
-How can I trouble shoot my api key to be sure it is not the
root cause of the problem? (i.e. incorrect)
-Does anyone know if there really is a check against the api key that
would prevent the application from launching?
(This would mean that map activities require network access in order
to be launched?)
Thanks again,
Josh Beck

I can maybe help here. I'm an amateur, but the 'out of memory' error is a familiar adversary. The VM only allows you to use 640k at any given time.

[android-developers] Marketplace --Demo vs Full Version--
Hello all, I have an app on the marketplace right now that is doing fairly well. When paid apps arrive, I'd like to change a few variables in my code and republish the code so a 'demo' and a 'full' version exists. I did some experimenting with this about a month ago and I'd like to get some input. If I change the folder structure from, com->mydomain->myapp to com -> mydomain -> myapp_full_version will the marketplace then recognize as a fully independent application? I tried changing the package name in the workspace and tweaking the manifest, but the marketplace transferred everything over and it wasn't seen as a 'new and separate' program.

[android-developers] screen orientation question
Hello all, I am trying to determine exactly what happens when the screen orientation changes. (What I mean is, what happens to the lifecycle of an app when the user slides the screen out.) Reason: I show a dialog in my app. If the user slides the screen out, the app crashes with 'View not attached to window manager error.' Is onPause called or something else? I'm thinking if I can slip a progressdialog.dismiss(); into an override, I'll be able to eliminate that particular element when the screen changes.

[android-developers] ACTION_VIEW uri.parse options (System Settings)
Ok, If I create a new intent like this:
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://
search?q=pname:com.android."));
It launches the market.
A couple of questions:
-Where is this "Market://" uri intent documented? (I can't seem to
find it.)
-What would I use to send the user directly to the system settings.
(Location and Security)

Question: By calling Camera.stopPreview(); It should also free up the Camera device, right. It's the preview that's drawing power I think.

[android-developers] System Timeout: Force Close/Wait
Is there a way to increase the system timeout so it won't throw the 'Force Close' screen so soon. I have an app that relies on web requests, and if they take too long, the user gets the Force Close prompt. (Push Wait and it works fine.) Thanks!

[android-developers] Button Resource Invalid?
Ok, I am trying to get a button to pop up. When I add :

Logcat tells me the resource is invalid.
Code:
b.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
int z = 5;
}
}

[android-developers] Re: Thread Question
First, thanks. I tried blocking the main thread, and quickly determined it wasn't a good idea. Didn't solve anything, but hey at least I know now. Here's what I'm working on: I have an application. It downloads a bunch of data and then loads that data into variables which are used to present the user with an initial display. If I load the variables and show the display the screen just goes black for like 20-30 seconds. If I background the thread, the variables aren't loaded prior to the display being drawn. Ideally, I'd like to use the progressbar to show a loading screen, but the loading bar doesn't show up unless the primary view is ready. I'm think the solution is to have the program start an initial activity that is small and prompts the user for a button press. That button press then activates a thread/ progress bar which in turn uses an intent to open the "primary" view. Make sense? If I have two separate activity files working in the same project, can I create public variables that are shared?

[android-developers] Create Drawable and Store Resource from Bitmap
I need a series of images loaded into an array like this:
// Load an array with BitmapDrawable resources.
private Integer[] mThumbIds = {
R.drawable.sample_thumb_0,
R.drawable.sample_thumb_1,
R.drawable.sample_thumb_2,
R.drawable.sample_thumb_3,
R.drawable.sample_thumb_4

Right now I have Bitmap bm = Valid_Bitmap_Image
How do I convert and store the bm object so that I can reference it
with a drawable
integer id ?

[android-developers] Question about View, Canvas, and Drawable.. --Basics
Hello all, Is this correct? View: The android screen is divided up into views. Views are basic layout objects. Canvas: You need to have at least one canvas if you want to do any drawing. Each view potentially has its own canvas. Drawable: ---)This is where my 10:30 bedtime turns into a 2:30 am nap in the chair before work.) -What is the difference between a Bitmap and a Drawable?

[android-developers] Simple Level App
Ok, so I wrote an app tonight that reads the 'Roll' data from the
compass and levels a line
on the screen. (It's on marketplace. It's also here:
http://www.imakmud.com/level.apk
) --Source Code Below:
Here's how it works:
-Basically every time the compass data changes, the canvas is
rotated and redrawn. It's very fast I think.
Problems I'm experiencing:
What I've got there is a single view with a single canvas. I'd like to
incorporate some
static elements like a pointers that don't rotate with the rest of the
canvas.
I experimented with drawables, but I'm just not sure that's the
answer.
So, I'm looking to have multiple graphics on the screen. One rotates,
the others don't.
Any direction is appreciated. --God this device is awesome!

Ok, this keeps the background and draws a circle on top of it when I
touch the screen.
Question: How do you think I might get it to keep the old circles when
I draw new ones.
Right now when I click the canvas is completely redrawn and the first
circle I created is lost.
Thanks, that helped a lot.

Thanks a million. I'll try this today and report back. I appreciate it. When you say 'set a flag.' Do you mean like an int? 0 or 1 kind of thing?

[android-developers] SImple Draw Program --Advice Needed
I watered this code down as much as possible for easy reading. Here is what it does: It draws a bitmap image to the screen. --darkcleanlinux (This part works.) It's the OnTouchEven(MotionEvent event) function that doesn't work. -I'm not sure I'm using the mCanvas object correctly. I would think that it would place a big dot on the screen when touched. Instead, it crashes. Any advice for a newb? Thanks --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Emulator Calendar Code --What's up?
Here is a very simple code segment I am running on the emulator.
It creates a new Calendar cal and reads cal.HOUR and cal.MINUTE
it then prints those values to the screen.
The emulator always reads 10 12
?
Any ideas?
Thanks,
package com.android.date;
import android.app.Activity;
import android.os.Bundle;
import java.lang.Object;
import java.util.Calendar;
import java.util.GregorianCalendar;
import java.util.Date;
import android.os.Bundle;
import android.widget.TextView;
public class date extends Activity {
/** Called when the activity is first created. */
Calendar cal = Calendar.getInstance();
int hour = cal.HOUR;
int minute = cal.MINUTE;
/** LOOK HERE -- tv.setText(hour + " " + minute)
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView tv = new TextView(this);
tv.setText(hour + " " + minute);
setContentView(tv);
}
}
