[android-beginners] Re: Adding Undo feature in FingerPaint app bundled with APIdemos.
@Romain: thanks for your reply...I'd *like* to believe that you wrote FingerPaint and would help me here :) Most of the applications in the Android Market(PicSay et al.) that provide a similar feature(drawing strokes on canvas) provide Undo functionality. I was trying to imitate the same in the original FingerPaint app. My approach to implementing this feature,as already mentioned in the earlier post, would be to: 1. memorize all the paths, 2. reset the canvas and 3. redraw all the paths again expect the last one. I was wondering if there was any alternative to this? Is there any class in the framework that can help me here? Please help. Thanks again!

I was looking at the android.graphics.Canvas class and therein I found a few methods that caught my interest. canvas.restore() and canvas.save(). But I couldn't get them to work per my requirement. One of the approach could be memorizing all the Path(representing strokes drawn) and then resetting the canvas and reapinting all the stroked one by one except the latest. I somehow dont like this approach. How do I undo my drawings on canvas? Please help.

1. You are better served doing this in the manifest via the
android:theme attribute. That way, the title and status bars will be
gone immediately, rather than after onCreate() returns.
2. Yes, you have to do this on every activity for which you want the
full screen. Bear in mind that what you want should be secondary to what
the user wants, and users tend to want to see their battery level,
signal strength, and such. Hence, please be judicious about your use of
full-screen themes.

[android-beginners] Re: someone plz help me .. how to call built in camera app from my custom app ??
Do some debugging work... The PackageManager can give you a list of all applications on your phone. Step through them and find the Camera application and note the package name of the camera application. Assuming you have done that, you can do something similar to the following (obviously putting in checks for the case the application doesn't exist, etc...): String packageName = package name found in above steps; PackageManager mgr = getPackageManager(); Intent intent = mgr.getLaunchIntentForPackage(packageName); startActivity(intent); If the getLaunchIntentForPackage method returns null, as it sometimes does, then you will have to create a new intent instead with something similar to this: Intent intent = new Intent(); intent.setClassName(packageName, className); I have not looked into how to find the className of an arbitrary application but I'm sure with a little work you can figure it out. I have already explained to you how to do this, both in these forums and when you emailed me directly. Rather than continually posting the same question over and over and waiting for someone to do your coding for you and give you complete functional code, I would suggest looking through the developer guide and the SDK reference docs and trying to figure it out for yourself. http://developer.android.com/reference/packages.html http://developer.android.com/guide/index.html Thanks, Justin -- There are only 10 types of people in the world...

I added following in the manifest.xml

app_name
android:theme=@android:style/Theme.NoTitleBar.Fullscreen
android:screenOrientation=landscape
and the application is full screen enabled !
as you correctly said ... by this mechanism i am able to see the full
screen effect immediately ... whereas previously i used to see the
titlebar for fraction of second!
well ... i am developing an application which would run on an android
device (and not the android phone!) ...
so i want the application to start immediately after the device is
powered on (and booted successfully)
i am planning to show the battery strength , n/w strength etc on the
home screen of my application ...
lets see ...

[android-beginners] Re: Development Phone
I can't seem to find the answer to this anywhere, so if someone could take a crack at it or point me in the right direction, I would appreciate it. I have the Google Ion (the phone handed out at the Google IO Developer's Conference), but I have no idea how to upgrade the OS to 1.6. The HTC support website has some information on how to do it and the necessary files, but the instructions are way above my head (I don't know where to input a command line, how to bootload, or anything). I got this as a gift and really want to upgrade it to 1.6 so any help would be appreciated. Anybody have time this weekend to provide an Android for Dummies type of explanation? Thanks! ~Gene On Sep 17, 6:02 pm, brucko geoff.bruck...@gmail.com wrote: I'll be the first to admit that I am a bit of a novice in the android arena. What I would like to bring to your attention is that there may well be very good reasons as to why some pre-installed apps can be hard to change. I'm trying to import some devices into Australia, many of our regulations are based on the US and Europe. If you change some of the key software on a phone you may very well make it illegal to use that phone. One key example would be the requirement we have to be able to dial emergency numbers even when the screen is locked. Someones life may depend on this functionality being intact. I have no idea what the legal ramifications would be of making software available that did not maintain this ability. However selling, giving or even loaning phones with emergency dialing no longer enabled would certainly be an offense.

There are many areas where very small decisions of questionable wisdom in default applications really hamper the user experience (even in the using it just to make calls sense), but these can't be very readily changed on a retail phone, particularly the parts most closely involved in the telephone functionality. As of this moment, I believe most of the retail phones are probably still shipping with an easily rooted linux kernel, but that probably will get closed up (already fixed in google's tree) and they will be limited until another hole is found. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

[android-beginners] Updating Google Ion from 1.5 to 1.6
I have a Google Ion (the version of the HTC Magic that was handed out at the Google IO Developers Conference) that was given to me as a gift. Unfortunately, I have no idea how to update the OS on the phone to 1.6. I looked up the HTC support website and I have all the necessary files, but I have no idea how to execute any of the instructions. HTC tech support directed me to this community. Just to highlight my level of ignorance: I don't know how to use a command line, I have no idea what a bootloader is, I don't know how to use the SDK (although I have it on my computer and I installed Eclipse as well), etc. If anybody has time to run through a true Android for Dummies guide to upgrade my phone to 1.6, I would be forever grateful.

[android-beginners] Socket client does not work with emulator

try

Socket socket = new Socket(localhost, 5554);
PrintWriter out = new PrintWriter(echoSocket.getOutputStream

}
catch(Exception e)

out.println(Hello World);
This program works perfectly and my server.c file receives the
message.
However, when I try the same program with the Android Emulator, I get
an Error:java.net.ConnectException: localhost/127.0.0.1:5554 -
Connection refused I have tried different ports as well (, 3490).
This works perfectly with the regular Java project, but the moment I
write the same code in an Android project I get that error. I have
been stuck on this all day and am really getting frustrated :( Would
appreciate any help!

[android-beginners] Re: How to use the Network Manager?
Based on your preferred interface list, I would first do a scan on Wifi. Look for open Wifi networks to connect without security codes. Otherwise open a dialog that the user can enter the security information for the secured network. If no Wifi network is available turn off Wifi which automatically triggers to connect to cellular data. Have a broadcast receiver implemented to check for network changes. When you receive a network change you can use the code below to find out what your actual network is. To find out about your current connection: ConnectivityManager connection = (ConnectivityManager) mContext.getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo networkInfo = connection.getActiveNetworkInfo(); Log.d(TAG,type:+networkInfo.getTypeName()); To connect to a wifi network you have to create a WifiConfiguration. After adding your configuration to the WifiMgr with mWifiMgr.addNetwork(wifiConfiguration); you can connect to the network with boolean successConnected = mWifiMgr.enableNetwork(inetId, true); In your broadcast receiver you should receive an intent about the network status change. -- Roman Baumgaertner Sr. SW Engineer-OSDC ·T· · ·Mobile· stick together The views, opinions and statements in this email are those of the author solely in their individual capacity, and do not necessarily represent those of T-Mobile USA, Inc.

[android-beginners] Re: Socket client does not work with emulator
Localhost (127.0.0.1) is the address of the phone or the emulator. I
assume that your server program in C is on your devlopment machine.
So you need to connect to your PC's IP address.
You can use ADB
http://developer.android.com/guide/developing/tools/adb.html
to setup port forwarding from the device to your PC.

The emulator does not understand when you specify localhost
So change the line:
Socket socket = new Socket(localhost, 5554);
to
Socket socket = new Socket(10.0.2.2, 5554);
Cheers!

Hi,
I am trying to create a connection between a server socket program
written in C and an android client socket program. Now when I write a
regular java client program such as:
try
{
Socket socket = new Socket(localhost, 5554);
PrintWriter out = new PrintWriter(echoSocket.getOutputStream
(), true);
}
catch(Exception e)
{
//
}
out.println(Hello World);
This program works perfectly and my server.c file receives the
message.
However, when I try the same program with the Android Emulator, I get
an Error:java.net.ConnectException: localhost/127.0.0.1:5554 -
Connection refused I have tried different ports as well (, 3490).
This works perfectly with the regular Java project, but the moment I
write the same code in an Android project I get that error. I have
been stuck on this all day and am really getting frustrated :( Would
appreciate any help!

[android-beginners] Re: 1.6: Quick search box to pass parameters to an application
Nevermind, found the SearchableDictionary example in the SDK which gave me enough. On Oct 8, 9:24 am, Danny Brain tehdan...@gmail.com wrote: Hey, I was wondering if it were possible to use the quick search box to pass parameters to an application? E.g. If I had a timesheet application called HagridIsHugeAndAnnoying, I'd want to be able to enter: hihaa 7hrs sleeping in the quick search box and an action of Create time entry ... would show up in the results. This would launch an intent and either just say Yay done or if it needs user intervention show a dialog / screen. So I guess I'd want to be able to say search hihaa anything should call Intent X and Intent X should be able to parse the query.

[android-beginners] OpenGL and transparent PNG's
I'm having a problem with transparent 32-bit PNG's on both the emulator and the G1. They load fine, but I can't change their alpha value unless the texture is fully opaque to begin with. For a simple example: glEnable (GL_BLEND); glBlendFunc (GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); glBindTexture(GL_TEXTURE_2D, fully_opaque_texture); // all pixels are opaque glColor4f(1, 1, 1, 0.5); glDrawArrays( ... ) // displays half transparency (correct) ... glBindTexture(GL_TEXTURE_2D, transparent_texture); // some pixels are transparent glColor4f(1, 1, 1, 0.5); glDrawArrays( ... ) // displays as fully opaque (wrong) I've also tried the following (as suggested on another thread) with no luck: setEGLConfigChooser(8, 8, 8, 8, 0, 0); getHolder().setFormat(android.graphics.PixelFormat.RGBA_); --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

[android-beginners] Querying AlarmManager to determine if alarms are set
Hi there, does anyone know if its possible to query the AlarmManager to see if/what alarms are set? I can set an alarm using: AlarmManager am = (AlarmManager)getApplicationContext().getSystemService (Context.ALARM_SERVICE); Intent i = new Intent(getApplicationContext(), OnAlarmReceiver.class); PendingIntent pi=PendingIntent.getBroadcast(getApplicationContext(), 0, i, PendingIntent.FLAG_CANCEL_CURRENT); am.setInexactRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime(), Const.UPDATE_INTERVAL_MS, pi); And i can then cancel it using: am.cancel(pi); But i can not figure out how to determine if the alarm is still set (e.g. so an activity can inform the user that the scheduled task is already set). AlarmManager has not isSet() method. Can anyone shed any light on this? Is it even possible? many thanks in advance. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

[android-beginners] Using the SAX parser in a static method
i am trying to parse an XML file using SAX. The problem is that I
need to make the method Static because I want to run this method
inside the onCreate methods of the DatabaseHelper class (Which is
a static inner class).
This is not really an android issue but a scope issue.
The problem is at this line:
XmlListHandler listXmlHandler = new XmlListHandler();
Eclipse shows me this error:
No enclosing instance of type SpellDroidDbAdapter is accessible. Must
qualify the allocation with an enclosing instance of type
SpellDroidDbAdapter (e.g. x.new A() where x is an instance of
SpellDroidDbAdapter).
/*
* Insert a List into the database from an XML file
*
* @param xmlFile a List XML file
*/
public static void insertNewListFromXML(File xmlFile) {
try {
/* Get a SAXParser from the SAXPArserFactory. */
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
/* Get the XMLReader of the SAXParser we created. */
XMLReader xr = sp.getXMLReader();
/* Create a new ContentHandler and apply it to the XML-
Reader*/
XmlListHandler listXmlHandler = new XmlListHandler();
//Set the Handler
xr.setContentHandler(listXmlHandler);
// Parse the xml-data from our URL.
xr.parse(xmlFile.getAbsolutePath());
} catch (Exception e) {
/* Display any Error to the GUI. */
Log.e(TAG, List Insertion Error, e);
//TODO display a toast to the user of the error

[android-beginners] Best way to reposition contents of ListView at the top?
I have a ListView which displays the results of some search. When the user makes a new search I repopulate the underlying Array of an ArrayAdapter and call notifyDataSetChanged(). However, if the user has previously scrolled down in the ListView then the scrolling is not then reset to the top - I can see why this is the way it is (to support incremental changes to the contents).

I notice that if setSelection(0) is called just before notifyDataSetChanged() it doesn't work - i.e. its as if setSelection (0) didn't do anything. However, switching the calls around works for me.

Hi,all.
The app I wrote doesn't run correctly on the device.Could someone give
me a suggestion that how to solution this problem.

--
MediaRecorder recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(/sdcard/test.amr);
try {
recorder.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
Log.e(Tag, IllegalStateException);
e.printStackTrace();
} catch (IOException e) {
