[android-beginners] Adding a view to a viewgroup
I'm trying to do some simple UI stuff in a game (Basketball).
I've created my own Court class (which extends ViewGroup) and I want
to add a Ball (extends View) to the court.
Unfortunately my ball doesn't show up on the court, and in fact the
court doesn't draw either.
What have I done wrong?

/** Called when the activity is first created. */

public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
this.addContentView(new Court(this), new LayoutParams(FPAR,
FPAR));
}

this.layout(0, 0, width, height);
// create a new ball
ball = new Ball(this, 100, 100, 20, Color.RED);
// put a ball on the court
this.addView(ball);
}

[android-beginners] Re: Adding a view to a viewgroup
Your Court.onDraw() function will not get called by default for
efficiency. You need to call setWillNotDraw(false) to enable it.

[android-beginners] GUI test tool/framework for Android?
Hi All, I need to interact with my Android application through its GUI in order to test it. Is there any tool/framework available which can be used to perform various user actions on the UI elements/controls like a button click, read/write some text into a textbox etc.? There is an "Android Instrumentation Framework" (part of SDK) but that's more for API or Unit testing not for functional testing.

[android-beginners] connection via adb
Hello, I see posts about this scattered everywhere, so I apologise that this is somewhat travelled ground, but I haven't been able to find categorical answers to my questions. I bought a G1 recently and downloaded the Android SDK. I have a Mac and a PC, and I installed the SDK for each. When I connect and try to see my device using 'sudo adb devices' on my Mac, I get "List of devices attached" with no entries. On my PC, when I plugged the phone in I saw a popup in the System Tray that said 'Android phone' but I didnt get the chance to install the drivers that came with the SDK for XP, and again when I run 'adb devices' I get "List of devices attached" with no entries. Do I need to change the firmware that my phone is running? My firmware is 1.1, baseband 62.33.20.08H, Kernel 2.6.25, build kila-user 1.1 plat-rc33.

[android-beginners] Android 1.5 - getNeighboringCellInfo() always returns 0 neighboring cells
Has anyone been able to retrieve the neighbor cell information using a
G1 or ADP phone?
I'm using android-sdk-linux_x86-1.5_r2 and compiling against API level
3 (Android 1.5).
The application builds correctly but every time I request the
neighboring cells as listed below, it returns a list of 0 neighbors.
If I look at the radio log buffer, I can see the request being made to
the RIL layer.
Is anyone else seeing this?
Here are the permissions in AndroidManifest.xml
Here is the code:
// Retrieve the telephony manager
mTelephonyManager = (TelephonyManager)getSystemService
(Context.TELEPHONY_SERVICE);
// Get the neighbor cell information
ArrayList neighbors =
(ArrayList)
mTelephonyManager.getNeighboringCellInfo();
Log.d(TAG, "Number Of Neighbors: " + neighbors.size());
// Print out the neighbor cells
for (NeighboringCellInfo neighboringCellInfo : neighbors) {
Log.d(TAG, "NeighborCell: " + neighboringCellInfo);
}
Any help would be greatly appreciated!

[android-beginners] Updating items in ListView
Hi all! I have a ListView (to be more exact I have a ListActivity) and the list receives it's info from a remote source in a separate thread. The list first just receive a list of integers and then I'd like to send separate requests for the list items data that are visible. So, I guess I have 2 questions: 1. How do I know what items are visible? Is it only the items that are requested through the adapters getView? 2. Since it takes a little while from the moment an item gets visible until it actually have it's visible data loaded: How do I tell the List/Adapter to invalidate/redraw one item in the list?

[android-beginners] MapView drag delay
Hello, I have a question regarding the mapview and it's drag delay! At least on the emulator, when you drag the map around in a MapView it will lag for a few pixels before it starts to move. I'm guessing this is because it need some a initial calculations or something, but I wonder if you KNOW why this delay is and if there is any possibility to remove it? // Kalle --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

If you are using eclipse to dev then you know the emulator is all part of what you are looking for. If you are not using eclipse then you should probably start using it. Go to http://eclipsesource.com/en/yoxos/yoxos-ondemand/ and roll your own eclipse install with all the android, svn, jUnit stuff or whatever you like and you should be good to go. g On Mon, Jul 6, 2009 at 6:37 PM, Yasser wrote: > > I need to interact with my Android application through its GUI in > order to test it. > > Is there any tool/framework available which can be used to perform > various user actions on the UI elements/controls like a button click, > read/write some text into a textbox etc.? > > There is an "Android Instrumentation Framework" (part of SDK) but > that's more for API or Unit testing not for functional testing. > > > Thanks > Yasser > > > > > --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] Re: GUI test tool/framework for Android?
I am running my app on the android emulator. I am looking for a tool through which I can programatically perform (simulate) user actions on the app's GUI. A tool like WinRunner or QTE (may be not that advanced) which can interact with the GUI. Actually I need this to develop test automation for my app. On Jul 7, 1:25 pm, Gabriel Branch wrote: > If you are using eclipse to dev then you know the emulator is all part of > what you are looking for. > If you are not using eclipse then you should probably start using it. > > Go tohttp://eclipsesource.com/en/yoxos/yoxos-ondemand/and roll your own > eclipse install with all the android, svn, jUnit stuff or whatever you like > and you should be good to go. > > g > > > > On Mon, Jul 6, 2009 at 6:37 PM, Yasser wrote: > > > I need to interact with my Android application through its GUI in > > order to test it. > > > Is there any tool/framework available which can be used to perform > > various user actions on the UI elements/controls like a button click, > > read/write some text into a textbox etc.? > > > There is an "Android Instrumentation Framework" (part of SDK) but > > that's more for API or Unit testing not for functional testing. > > > Thanks > > Yasser- Hide quoted text - > > - Show quoted text - --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

Also, you should not call this.layout(0, 0, width, height) from
onMeasure(), it will be done for you.

Thanks Mark. I will look more into the instrumentation framework.

Use the instrumentation framework. You can access all your activity's widgets, in part because you are handed the Activity object itself.

[android-beginners] Problem with Displaying Web Server's Response (Text) in Android
Hello, the following code uses POST method to communicate with the Web
Server, and the response is displayed in the console (not parsed in a
Servlet, etc). When compiled as a java application, the program works
as expected returning the response as html text.
My aim is to have an Android app that will communicate with servers
using various protocols- and I am using this as an example in learning
how that technique can be done. Therefore I would wish Android to get
the response, and displaying it in 'TextView?' or somewhere. I thought
this was going to be a straight-forward thing, but I have been stuck
at this point for days now.
Can somebody assist if possible.
Thanks. The code follows
package Com;
import java.net.*;
import java.io.*;
public class FormPoster {
private URL url;
private QueryString query = new QueryString();
public FormPoster (URL url){
if (!url.getProtocol().toLowerCase().startsWith("http")){
throw new IllegalArgumentException("Posting only works for http
URLs");
}
this.url = url;
}
public void add(String name, String value){
query.add(name, value);
}
public URL getURL(){
return this.url;
}
public InputStream post() throws IOException {
URLConnection uc = url.openConnection();
uc.setDoOutput(true);
OutputStreamWriter out = new OutputStreamWriter(uc.getOutputStream
(), "ASCII");
out.write(query.toString());
out.write("\r\n");
out.flush();
out.close();
return uc.getInputStream();
}
public static void main(String args[]){
URL url;
if (args.length > 0){
try{
url = new URL(args[0]);
}
catch (MalformedURLException ex){
System.err.println("Usage: java FormPoster url");
return;
}
}
else {
try{
url = new URL("http://www.cnn.com";);
}
catch (IOException ex){
System.err.println(ex);
return;
}
}
FormPoster poster = new FormPoster(url);
poster.add("name","Charles");
poster.add("email", "ma...@yahoo.com");
try{
InputStream in = poster.post();
InputStreamReader r = new InputStreamReader(in);
int c;
while((c = r.read())!= -1){
System.out.print((char) c);
}
System.out.println();
in.close();
}
catch (IOException ex){
System.err.println(ex);
}
}
}

You should try some of the tutorials on http://developer.android.com. What you have is fine for desktop Java but bears little resemblance to an Android app, any more than it bears much resemblance to a Swing or SWT app. Step #1: Get the Hello, World tutorial working http://developer.android.com/guide/tutorials/hello-world.html Step #2: Read up on AsyncTask Step #3: Create an AsyncTask that, in its doInBackground() method, does your HTTP processing, and in its onPostExecute() method, updates the TextView widget -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy _Android Programming Tutorials_ Version 1.0 In Print! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] Moving data from Phone to PC
I am developing an Android application that collects accelerometer sensor readings. I need to somehow get this data from the phone to a desktop computer. I want to have a "Send" button that sends the data. The closest I have come is that if put the data in the image Content Provider and say it's a jpeg (it's not), then I can email that as an attachment from gmail. But that is not an acceptable thing to ask users to do. Ideas? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] Traffic filtering options
I am looking for information on traffic filtering options on the Android platform. That is, filtering Internet traffic such as HTTP, and IM. For example, on the desktop this can be achieved via a device driver such as NDIS, Windows Filtering Platform (WFP) or a Layered Service Provider (LSP). What options exist on the Android platform? Is it possible to access the network / TCP/IP stack? We would like to initially create a Web/HTTP filter then move on to a Instant Messaging filter as well. We would like to do this via filtering 3rd party applications (e.g. any application installed on a Android device) or via a custom browser & prevent usage/installation of external browsers.

Only if you are creating your own firmware or are contributing modifications to the Android open source project: http://source.android.com Ordinary Java applications can use Java sockets, but only for their own application -- they cannot affect other applications' network activity (e.g., filtering). Discussion of such firmware changes are best suited for one of that project's lists: http://source.android.com/discuss > We would like to initially create a Web/HTTP filter then move on to a > Instant Messaging filter as well.

Note that "prevent usage/installation of external browsers" runs counter to Android's user-centric model.

The Search widget is indeed not an app widget but it's built in Home itself. You cannot create your own non-app widgets with the standard Home application (for security reasons.)
