[android-beginners] why use onCreateDialog?
i've been wondering this. why would i implement Activity.onCreateDialog()? why wouldn't i just create a new instance of the dialog i want, and call .show() on it? usually a dialog will close itself, but if i doesn't, i just keep a handle to it in a member field and call .dismiss(). --

[android-beginners] why Java, not Python?
Not trying to start a flame war here, just curious about the decision to use Java as the main language for Android development instead of Python. For one Python is one of the main languages used by Google, and both languages are byte-code interpreted. Python has a very rich set of libraries which make it easy to do things quite succinctly. For instance if I wanted to know how old a friend's baby exactly is I could do something like: from datetime import datetime start = datetime(2009, 10, 3, 9, 45, 0, 0) age = datetime.now() - start print 'Birthday/time :', start print 'Baby's exact age:', age Perhaps I don't know Java well enough, but this would be much more verbose/complex to do in Java. Again, not trying to start any arguments, just curious if anyone has any background on this.

[android-beginners] Why won't it start here?
Is there any problem with launching a service via an Alarm's BroadcastReceiver's onReceive? My service never has it's onCreate or onStart method called. My Alarm's receiver gets a wakelock, calls context.startService(new Intent(context, FmiDaemon.class)); (context given via onRecieve parameter), waits 3 seconds, then releases the lock. My service has 2 methods, onCreate and onStart. onCreate gets another wakelock, the end of onStart releases the wakelock, and calls "stopSelf". Both methods are supposed to send data to a log, but never do since they're never called. Where is the problem? Is that a bad "context" to use? Is onCreate and onStart the wrong methods to implement? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

Re: [android-beginners] why Java, not Python?
Anybody know what the number of Python developers vs. the number of Java developers? I would think that Java would have more developers. Maybe they were trying to go with the biggest developer base in hopes to get more apps up and running quickly.

Re: [android-beginners] why Java, not Python?
This is my theory. One of the creators of Android company, which android is based on, came from an company called Danger in mountain view. Danger made the sidekick - The applications made on the sidekick are all done in java. http://developer.danger.com/site/faq/show#q5 An natural evolution of the client side language for android based on the founders experience would be java.

Re: [android-beginners] why Java, not Python?
To my knowledge, Java is simply faster. That, and Python is also rather "big". With any luck, Unladen Swallow might find its way onto our devices.. then perhaps we can get Python onto Android. Personally, i would give my right leg for Python on android. (And by that, i mean Python working as well as, or better, than Java. Not that python scripting project, heh.)

[android-beginners] Why does getTop() return 0?
Hi guys,
I'm declaring some view inside my layout xml file and then I'm trying
to figure out their location with getTop(), bottom, right, left etc.
However, the end result is that it always returns 0, why is this?
Here is the implementation:
public TextView mDropHere;
public TextView mOne;
public TextView mTwo;
public LinearLayout mViewParent;
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
mDropHere = (TextView) findViewById(R.id.drophere);
mOne = (TextView) findViewById(R.id.one);
mTwo = (TextView) findViewById(R.id.two);
mViewParent = (LinearLayout) findViewById(R.id.viewparent);
Log.e("DropHere", Integer.toString(mDropHere.getBottom()) + "
" +
Integer.toString(mDropHere.getLeft()) + " " +
Integer.toString(mDropHere.getRight()) + " " +
Integer.toString(mDropHere.getTop()));
Log.e("mOne", Integer.toString(mOne.getBottom()) + " " +
Integer.toString(mOne.getLeft()) + " " +
Integer.toString(mOne.getRight()) + " " +
Integer.toString(mOne.getTop()));
Log.e("mTwo", Integer.toString(mTwo.getBottom()) + " " +
Integer.toString(mTwo.getLeft()) + " " +
Integer.toString(mTwo.getRight()) + " " +
Integer.toString(mTwo.getTop()));
Log.e("mViewParent",
Integer.toString(mViewParent.getBottom()) + " " +
Integer.toString(mViewParent.getLeft()) + " " +
Integer.toString(mViewParent.getRight()) + " " +
Integer.toString(mViewParent.getTop()));
}
Cheers,
Charles

[android-beginners] Why XML to define layouts/components?
My original first post doesn't seem to get approved, so let me try again. :) I'm wondering whether other Android newbies than me find the empathy on XML layout troublesome? I realize we should strive to separate view from logic and that XML is hip and trendy, but is it really necessary for these relatively simple Android applications? XML layouts involves more files and what feels like a lot of "magic" (type unsafe) properties, and makes samples harder to follow/ type. It also can't be especially efficient to use findViewById (whether BFS or DFS based) constantly? It sort of reminds me of the differences between JSF and Wicket, where the former was designed by people sitting in an ivory tower while the latter was designed for and by people at the ground, comfortable with Java. Which also leads me to wonder how come Android uses the old type- unsafe int enum pattern and also, why fluent-interfaces/method- chaining isn't used in greater extend? /Casper PS: You might want to fix the URL's to the group charter and FAQ as they currently go into 404. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] Why won't this Download Method work?
Hi Guys,
I'm new here, and I'm just trying to learn the ropes of android. Okay,
so here's my question:
I've got a method that I've tested successfully and found that it
works in Java. However, when I convert it over to android, and try to
run it on my emulator, it doesnt work. Basically, the method takes
the input parameters beginning, end, and URL, and downloads a file or
file segment from the URL parameter with beginning at byte position
beginning and ending at byte position end. In the emulator, it wont
download but in Java, it works just fine.
I've enabled internet permissions, and I've tested the other parts of
my activity so I don't think thats the problem. Heres my code, maybe
you guys can help.
public void download(int beginning, int end, String address) throws
IOException{
URL url;
int read = 0;
android.util.Log.d(TAG,"DL Started");
byte buffer[] = new byte[1024];
url = new URL(address);
URLConnection fileAddress = url.openConnection();
fileAddress.setAllowUserInteraction(true);
fileAddress.setRequestProperty("Range","bytes=" + beginning +
"-" +
end);
InputStream is = fileAddress.getInputStream();
DataOutputStream out = new DataOutputStream(new
BufferedOutputStream
(new FileOutputStream("/sdcard/Test")));
android.util.Log.d(TAG,"DL in the midst");
while (read !=300 ){
is.read(buffer);
out.write(buffer);
read++;
}
out.close();
android.util.Log.d(TAG,"File is:
"+fileAddress.getContentLength() +
" bytes");
//while((bytereader = is.read()) != beginning); // while byte
is not
beginning of the segment
//return 0;

[android-beginners] Why isn't this layout file working?
Here's what I want: two simple input fields, one labeled "Artist" and one "Title". Basically: Artist [ input ] Title[ input ] The two input fields (EditTexts) need to be aligned on a vertical axis, so that the application looks good. Thus, I used the TableLayout View. Unfortunately, it seems I just can't get the table cells to expand all the way. So here's how my layout looks like (the | represends the margin of the screen): Artist [ input ] | Title[ input ] | But I want the input fields to expand all the way. I could probably do it with a fixed width, but I don't think that's a good idea. Here's my main.xml file: http://schemas.android.com/apk/res/ android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > BTW, I know the is not currently needed, but I'll have to add some things below the table.

[android-beginners] Why do I need a ListView?
I've been fighting this for freaking hours: I can open my ContentProvider and assign data to variable. I know want to list all the records. I can't get anything to display. I've been trying to simply things and I've run into a road block: for some reason, I keep getting the error "Your content must have a ListView whose id attribute is 'android.R.id.list'". The problem occurs when I modify this layout file: http://schemas.android.com/apk/res/android"; android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > If I take out the ListView, I get the error, but I can't find out where in my code I'm referecing that. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] Why I can't delete SIM record?
Hi guys,
I can use code to delete contacts in phone, but I can't do it in SIM
card. Does anybody know it??
Here is my code to delete SIM record.
mSimUri = Uri.parse("content://sim/adn");
getContentResolver().delete(mSimUri, "name=?",new String[] {"people
name"});
No exception to execute this command, but not any result.
Can anybody give an eye on it? Thanks!

[android-beginners] Why XML to define layouts and components?
I'm wondering whether other Android newbies than me find the empathy on XML layout troublesome? I realize we should strive to separate view from logic and that XML is hip and trendy, but is it really necessary for these relatively simple Android applications? XML layouts involves more files and what feels like a lot of "magic" (type unsafe) properties, and makes samples harder to follow/ type. It also can't be especially efficient to use findViewById (whether BFS or DFS based) constantly? It sort of reminds me of the differences between JSF and Wicket, where the former was designed by people sitting in an ivory tower while the latter was designed for and by people at the ground, comfortable with Java. Which also leads me to wonder how come Android uses the old type- unsafe int enum pattern and also, why method chaining isn't used to greater effect. /Casper --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] Why won't Intent pass along the extras
I have a class object that I want to pass from one screen to another.
So I made it inherit from Parcelable and added the following code to
my class:
public class ItemDescription implements Parcelable {
/// property setters and getters
public int describeContents() {
// TODO Auto-generated method stub
return 0;
}
public void writeToParcel(Parcel out, int flags) {
out.writeInt(mData);
}
public static final Parcelable.Creator CREATOR = new
Parcelable.Creator() {
public ItemDescription createFromParcel(Parcel in) {
return new ItemDescription(in);
}
public ItemDescription[] newArray(int size) {
return new ItemDescription[size];
}
};
}
In response to an event, I do kick off another screen (Intent) and put
extras into it:
Intent mIntent = new Intent(v.getContext(), Item.class);
Parcelable itemDesc = getItemDescription(preset); // returns
ItemDescription
mIntent.putExtra("com.vbrad.android.mystapp.item1", itemDesc);
startActivity(mIntent);
In the onCreate event of this new activity, I attempt o retrieve the
contents of the itemDesc object in the following manner:
Intent intent = getIntent();
Parcelable p = intent.getParcelableExtra("com.vbrad.android.
mystapp.item1");
ItemDescription itemDesc = (ItemDescription) p;
However, the itemDesc object is unpopulated - all the internal
variables are at default values (e.g. 0 for numeric types, null for
everything else). It's like it was just created.
What am I missing here?
Thanks.

[android-beginners] why is bitmap .getWidth() and .getHeight() returning -1
im having trouble with why these values are being returned to me. the bitmap is being loaded using BitmapFactory.decodeResource() and the image loaded displays correctly when i draw it onto a canvas. however, the only quirk i've encountered so far is that i cannot retrieve the bitmap width/height. i've even moved the loading of the images from the constructor into the onSizeChanged() event of the view just to make sure that the unloaded view isnt affecting the results. any insights to this would be appreciated. cheers! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

Re: [android-beginners] Why does my racing game not work???
When an app force closes the best thing to do is look at the logcat output.
That should tell you everything you need to know about the problem.

Re: [android-beginners] Why does my racing game not work???
Not only that.. you're going to have to learn how to use logs/stack
traces/etc for future projects, so it's good to know how and learn to use it
rather than depend on posting your code and having someone else fix it.
Besides, after school comes a real job and you can't be posting a company's
source out in a public forum.

[android-beginners] Why are lockCanvas and synchronized(surfaceHolder) both needed?
All of the examples I have seen for drawing into a graphical view look
something like the following, but I can find no explanation for why:
canvas = surfaceHolder.lockCanvas(null);
synchronized (surfaceHolder) {
canvas.drawBitmap(bitmap, 0, 0, null);
}
surfaceHolder.unlockCanvasAndPost(canvas);
Why is the nested synchronized needed in addition to the unlock? What
might happen if the nested synchronized is omitted?

[android-beginners] Why does TextView.setText cause the enclosing ScrollView to scroll?
Hello!
I'm new to this group and (full disclosure) cross posting this
question here from StackOverflow, just because I'm not 100% sure how
my question will be found by other SO users (I made sure to read the
suggested "How To Ask Questions The Smart Way", and made sure to
search SO for a clear explanation, but I must have missed it). Here,
I'm clear that it'll be sent out to everyone, so here goes (my
apologies in advance if I shouldn't be cross-posting like this!)
I've got this odd problem which is happening on 1.6, 2.2, and a
MyTouch 3G Slide (which is API #7, and listed as "2.1-Update1" in the
Android Device Chooser).
The basic idea for my app is to make a stopwatch-sort of thing, in
that the user can tap a button to start a timer, then tap it again to
stop (pause) the timer; further taps alternate between resuming the
timer and pausing the timer.
I've got a top-level ScrollView which contains a RelativelLayout,
which contains a bunch of widgets. The first widget is a HUGE button
(so that it's easy to press), which pushes all my other widgets below
the bottom of the screen. This is intentional, as I want to rely on
the ScrollView (and an on-screen reminder to the user) to make the
rest of the input options available.
I've got a simple state-machine type setup, where mState is the
current mode (STATE_TIMER_NOT_STARTED before the user presses any
buttons, ...RUNNING after the first press, and then ...PAUSED after
the second, back to ...RUNNING after the third, etc, etc).
All this works great EXCEPT that when the timer is running, and the
user presses the start/stop/resume button again, the ScrollView will
scroll down a ways. I am NOT issuing this command (I don't even have
a reference to ScrollView object), and I'm not sure why it's doing
this.
REPRO:
Compile + run the below samples. When the app starts, press the
'Start Timing' button. Use your thumb (or the mouse) to touch-drag
the screen upwards (so you can see the RatingBar), then drag it back
downwards (so the button is again completely on-screen). Tap the
button (which now reads 'PauseTiming') again, and it'll jump down a
bit. It should NOT be jumping/scrolling down, since there's no
statement (that I can see) that tells it to scroll down. As near as I
can tell, it's the setText that causes the scrolling ( when I comment
those lines out, no scrolling occurs).
WHAT I'M ASKING FOR:
If I'm doing something dumb & you could point out what it is, I'd
really appreciate it! :)
***I wonder if 'touch mode' might have something to do with this,
since it does NOT appear to happen (in the emulator) when I use the
mouse's scroll wheel to move the panel upwards (i.e.,instead of the
simulated finger-dragging). I can't find a whole lot on touch-mode,
and nothing specific on focus/selection in touch mode within a
ScrollView
If you can confirm that this error occurs for you too, that would be
ok, too (since misery loves company.*AHEM* I mean, since it might help
confirm that it's not just me :) ).

[android-beginners] Why it is so difficult to generate gen file
Hi, I am a beginner trying to learn Android. I am trying to run Hello Android sample code but am facing one problem with generation of gen file. Sometimes it works after I do repeated clean, rebuild and build automatically on and off. I have installed android-sdk_r06-windows, eclipse-java-galileo-win32 and jdk-6u21-windows-i586. While creating Hello Android I am selecting Android 1.1 as SDK. I have given PATH variable of SDK only not for java. And I am working on Windows. If my simple Hello Android succeeds in generating R.java and then I make any changes in the main.xml and string.xml then again gen cannot be created. I am following file file:///D:/Android/android-sdk_r06-windows/android-sdk-windows/docs/resources/tutorials/hello-world.html Any help is highly appreciated.

[android-beginners] Why is my file not accesible at data/data ?
Hello,
I am trying to store an xml file.
When searching for solutions everyone suggests, that the just created
file has to be located at "/data/data/your_project_package_structure/
files/samplefile.txt"
Unfortunately neither on my emulator nor on the real device I can find
my file at this location
Here is my code:
-
try {
URL u;
u = new URL("www.asdf.com");
HttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(u.toString());
HttpResponse response = null;
response = httpClient.execute(httpGet);
HttpEntity entity = null;
if (response != null)
entity = response.getEntity();
InputStream is = entity.getContent();
FileOutputStream fos = openFileOutput("test.xml",
Context.MODE_WORLD_WRITEABLE);
byte buf[] = new byte[32768];
int len;
while ((len = is.read(buf)) > 0) {
fos.write(buf, 0, len);
}
fos.close();
is.close();
// I can read the file here and put it in a textview, so the file
actually exists..
} catch (Exception e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}

[android-beginners] Why atomic access to functions like CameraService::Client::takePicture()?
Hi, I seldom program multithreads. I am curious about why it needs a Mutex::Autolock to protect access to CameraService::Client::takePicture ()? We don't have multiple camera clients, right? Is it for preventing consecutively taking pictures? Thanks! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] Why not build an installer for android on WM phones?
I was wondering.. I've been following the android development for quite a time now.. I am certainly not an developer but why doesn't the android group bring out an application with wich u can simpel install android over your current windows mobile.. I know that there are lot's of things that may give error like unkown hardware and stuff.. But if there is an application made that you can run on your pc (win,mac,linux) witch can detect what sort of hardware your phone has and if its capitble of running android (1.5) then it would over you to install it from your desktop.. And the software alsof should backup the original windows mobile rom file.. I was suprised they didn't do this already because it wouild be a great change for Android to really steal some of the windows mobile market.. Is there any changes such an idea is possible?

[android-beginners] Why does android.opengl.matrix use floating point instad of fixed point?
I noticed that the android.opengl.matrix class uses floating point numbers for everything and as far as I can tell there isn't a fixed point equivalent. However, elsewhere (ie: sample project) it's mentioned that fixed point is faster since android devices are likely to not have an FPU. Also, OpenGL ES has fixed point versions of every function I've looked at thus far, so I'm assuming you could write most of your program with fixed point only. So, why does android.opengl.matrix use floating point if it's known to be slow and has a faster alternative? I could understand if there was another Matrix class that used fixed point, but from what I can tell there isn't. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] Why does using People._COUNT cause IllegalArgumentException to be thrown?
Hello,
I am learning about Content Providers, and tried the example from the
official Android tutorial on the topic. Please see the code below:
package com.example.devguide;
import android.app.Activity;
import android.content.ContentUris;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.provider.Contacts.People;
import android.util.Log;
public class ContentProviderExamples extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
/* Use the ContentUris method to produce the base URI
* for the contact with _ID == 23. */
Uri myPerson = ContentUris.withAppendedId( People.CONTENT_URI, 23 );
/* Alternatively, use the Uri method to produce the base URI. */
myPerson = Uri.withAppendedPath( People.CONTENT_URI, "23" );
/* Query this particular record. */
Cursor c = managedQuery( myPerson, null, null, null, null );
/* Form an array specifying which columns to return. */
String[] projection = new String[] { People._ID,
//People._COUNT, //throws
IllegalArgumentException
People.NAME,
People.NUMBER };
Log.i( "CPE", "projection[] = " + projection );
/* Get the base URI for the People table in the Contacts content
provider. */
Uri contacts = People.CONTENT_URI;
/* Construct the query. */
Cursor managedCursor = managedQuery( contacts,
projection,
null,
null,
People.NAME + " ASC" );
showColumnData( managedCursor );
Log.i( "CPE", "End of current code" );
}
private void showColumnData( Cursor c ) {
if ( c.moveToFirst() ) {
String name;
String phoneNumber;
String imagePath;
int nameColumn = c.getColumnIndex( People.NAME );
int phoneColumn = c.getColumnIndex( People.NUMBER );
do {
/* Obtain the field values. */
name = c.getString( nameColumn );
phoneNumber = c.getString( phoneColumn );
Log.d( "CPE", "name = " + name + ", phone = " + phoneNumber
);
} while ( c.moveToNext() );
}
}
}
However, the example given did not work, because calling managedQuery with
the array projection as one of the arguments resulted in a
IllegalArgumentException (java.lang.IllegalArgumentException). Android says
that the column "_count" which is the value of the element People._COUNT in
array projection is invalid. Can anyone explain to me the reason for this
exception, even though the names of all the columns are as per the API
specification?
Please see the output of LogCat below:
08-26 12:06:20.330: ERROR/AndroidRuntime(1112): java.lang.RuntimeException:
Unable to start activity
ComponentInfo{com.example.devguide/com.example.devguide.ContentProviderExamples}:

[android-beginners] Why more than one buttons are highlighted on one screen
Hi,
There are 15 buttons on the screen of my application. Normally only one
button is highlight, for example buttonA. But if I press buttonB for a long
time and/or multi-times it will be highlight too. And the buttonA is still
highlight. So two buttons are highlighted. Use the same way three or four
buttons will be highlighted at same time on the screen. If I use direction
key to move the cursor over all the highlight button then only one button is
highlight.
I use button to change frequency in my program. If pressing button in less
than FIRST_DELAY it only changes frequency one step. It will change one more
step for every CONST_DELAY after FIRST_DELAY. It works fine. The issue is
the highlight when pressing a long time.
I put the program bellow:
private Handler switchHandler = new Handler()
{
@Override
public void handleMessage(Message message)
{
if( MESSAGE_INCREASE_CHANNEL == message.what )
{
//
sendEmptyMessageDelayed( MESSAGE_INCREASE_CHANNEL, CONT_DELAY);
}
}
}
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
Button button = (Button)findViewById( R.id.radio_channel_up);
button.setOnTouchListener( new View.OnTouchListener() {
public boolean onTouch(View view, MotionEvent event)
{
if( view instanceof Button )
{
if( MotionEvent.ACTION_DOWN == event.getAction() )
{
//
switchHandler.sendEmptyMessageDelayed(
MESSAGE_INCREASE_CHANNEL, FIRST_DELAY);
return true;
}
}
return false;
}
});
}
Thanks,
Shude

make them float down to the bottom of the screen just like real

I had JDK1.6, SDK2.0, and set the enviroment path and classpath. I don't

[android-beginners] Why the Android.Editor.commit return false, But the value is OK
I have a problem in following code:
Activity---HelloAndroid
..
btnSpp.setOnClickListener(new View.OnClickListener(){
public void onClick(View v){
Intent i=new Intent();
i.setClass(HelloAndroid.this,
SharePreferencePage.class);
startActivityForResult(i,REQUEST_TYPE_B);
}
}); // Jump to another input screen
...
protected void onActivityResult(int requestCode, int
resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
..
TextView txt = (TextView)findViewById(R.id.txt);
SharedPreferences
sp=getSharedPreferences("Text",0);
android.util.Log.d("HA","
>"+sp.getString("Text", "none"));
txt.setText(sp.getString("Text",
"null"));
..
} //Accept the return value from sharedPreferences
Activity--SharePreferencePage
..
btn.setOnClickListener(new View.OnClickListener(){
public void onClick(View v){
result=et.getText().toString();
SharedPreferences
sp=getSharedPreferences("Text",0);
SharedPreferences.Editor edit=sp.edit();
edit.putString("Text", result);

setResult(Activity.RESULT_OK);
}catch(Exception e){
android.util.Log.d("SPP",">expetion:"+e.toString());
}
finish();
}
});
.
=
The problem is in "boolean b=edit.commit();" , it's always false. But
the value is set successfully. And can be get from SharedPreferences
sp=getSharedPreferences("Text",0);
In Spec, commit() return false mean write flase. Why in this case it
will return false?

[android-beginners] Why on Earth is it so hard to set up the development environment?
I've used PHP/Apache/mySQL/HTML/CSS/JavaScript for years. I've also do a bit of ASP and vBasic coding. In order to use these tools I've had to install various development environments in my time. But this Android Dev kit has me stumped. The installation instructions are not clear at all. Do I need to DL Eclipse first? Which order do things need installing? Its totally baffling and I understand why even my Android dev friends say that the iPhone OS dev kit is much easier to use. I've DLed and installed the Java JDK 6, Eclipse and the Android SDK. Eclipse wont start as it says it needs Java JRE, the Android SDK setup wont find the updates and says to enforce HTTP in the settings but in settings there IS no HTTP force, only HTTPS force - which is what is failing!!! Why on Earth can we not have one nice neat package that just installs it all for us? I already have to learn Java ffs, why should I have to wrestle with installing this? Is there any guide that is not on http://developer.android.com that isn't so incomprehensible? -- You received this message because you are subscribed to the Google Groups "Android Beginners" group.

Why the buffer is 0 when I play the "rtsp" movie from the internet?
I wrote a appliaction to play the movie from the internet.I try many
times and could not found out the reason ,so I decided to have a look
at opencore source code.
I look at the opencore source code ,and I find that it is the most
important code is below.But I could not find out how the percentage is
increasing .So I could not find out where the reason caused all
these.could someone give me a hand?

Re: [android-beginners] Why on Earth is it so hard to set up the development environment?
*> But this Android Dev kit has me stumped.* I have found it to be pretty straightforward... And so have hundreds, if not thousands, of other developers *> The installation instructions are not clear at all.* I would have to disagree... *> Do I need to DL Eclipse first? * No. You can develop in Eclipse or you can use any other IDE of your choice. The developer docs are very clear on that. There are separate pages describing how to develop in Eclipse ( http://developer.android.com/guide/developing/eclipse-adt.html) and how to develop in another IDE ( http://developer.android.com/guide/developing/other-ide.html). *> Which order do things need installing? * There is no order other than what makes sense... You can't install a plugin for Eclipse until you have actually installed Eclipse. The SDK can be downloaded before or after you install Eclipse. Java needs to be installed as well, and you may not be able to run Eclipse without installing it, but there certainly is no order of installation required. Also, this page describes exactly the order they recommend: http://developer.android.com/sdk/index.html *> Its totally baffling and I understand why even my Android dev friends say that the iPhone OS dev kit is much easier to use.* I have yet to see how it is totally baffliing... I have never developed for the iPhone but if the iPhone OS dev kit is ANYTHING like developing for OSX I fail to see how that is possible. I have done my fair share of developing for OSX and IMHO it royally sucks. *> I've DLed and installed the Java JDK 6, Eclipse and the Android SDK. Eclipse wont start as it says it needs Java JRE* When you downloaded and installed the JDK, did you install the JRE? If not, you need to install it. Eclipse is written in Java so you need to have the JRE installed in order to run it... You may need to add the location of Java's bin folder to your path for Eclipse to work. These are general java and Eclipse issues so far and have absolutely nothing to do with Android. *> the Android SDK setup wont find the updates and says to enforce HTTP in the settings but in settings there IS no HTTP force, only HTTPS force - which is what is failing!!! *If you would actually look at the option in the SDK Setup executable you would see that it says *"Force https://... sources to be fetched using http://..."* Seems to me this is exactly what you would want... *> Why on Earth can we not have one nice neat package that just installs it all for us? * Because then that would limit all Android development to a specific version of Eclipse and Java... And that would piss off a whole lot more people than you. Not to mention the hassle of having to coordinate an installer for the Android SDK, Eclipse, the ADT plugins for Eclipse, and Java... Multiple companies with multiple license agreements... Google would probably have to get specific license permissions from each of the companies that created this software to include these things in a *"nice neat package that just installs it all for us."* *> I already have to learn Java ffs, why should I have to wrestle with installing this?* You really don't have to learn Java if you don't want to... The choice is all yours. *> Is there any guide that is not on http://developer.android.com that isn't so incomprehensible?* Have you even taken the time to read the stuff on http://developer.android.com? 90% of the questions I answer on this group I get straight from that site. I fail to see how it is "so incomprehensible." It sounds like most of your problems aren't with Android but are with Java and Eclipse in general... And for some reason you feel the need to take it all out on Android. If you really are looking for help then I would suggest that you take a look at this site and then try asking for help again... the right way. http://www.catb.org/~esr/faqs/smart-questions.html Thanks, Justin -- There are only 10 types of people in the world...

[android-beginners] Why does my app "Stop Unexpectedly" every time I remove an item from myListView.
I am creating a sample example from a book. Its called "To Do List."
I'm at the point where I am working with the Options menu. I have the
options of adding and removing an item to a list. I can add items to a
list but every time I remove an item, the program "Stopped
Unexpectedly." Everything in my code seems to be fine. Ill show a few
sections of the code that have to do with the view.
static final private int ADD_NEW_TODO = Menu.FIRST;
static final private int REMOVE_TODO = Menu.FIRST + 1;
private boolean addingNew = false; // True if myEditText is visible.
False if not.
private ArrayList todoItems;
private ListView myListView;
private EditText myEditText;
private ArrayAdapter aa;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
myListView = (ListView) findViewById(R.id.myListView);
myEditText = (EditText) findViewById(R.id.myEditText);
todoItems = new ArrayList();
int resID = R.layout.todolist_item;

aa = new ArrayAdapter(this, resID, todoItems);
myListView.setAdapter(aa);
registerForContextMenu(myListView);
myEditText.setOnKeyListener(new OnKeyListener() {
public boolean onKey(View v, int keyCode, KeyEvent
event) {
if (event.getAction() == KeyEvent.ACTION_DOWN)
if (keyCode == KeyEvent.KEYCODE_1) {
todoItems.add(0,
myEditText.getText().toString());
myEditText.setText("");
aa.notifyDataSetChanged();
cancelAdd();
return true;
}
return false;
}
});
}

Debug it and look at the logcat info... It will give you more information
about the problem.

Re: [android-beginners] Why does my app "Stop Unexpectedly" every time I remove an item from myListView.
In the logcat, you will see a barrage of red colored lines. find the class
that removes the listview. it will tell you on which line the error occured.

[android-beginners] Why my application get "Not granting permission warning" when i install it by adb and AppsInstaller
Hi, All guru I am a beginner for android development. I found my application always get "Not granting permission" warning when I install it by adb and AppsInstaller as following. 03-18 16:01:05.882: WARN/PackageManager(56): Not granting permission android.permission.CALL_PRIVILEGED to package com.altigen.mobile.view (protectionLevel=3 flags=0x46) 03-18 16:01:05.882: WARN/PackageManager(56): Not granting permission android.permission.INJECT_EVENTS to package com.altigen.mobile.view (protectionLevel=2 flags=0x46) And my application cannot inject DTMF tone and mute the micphone on call, I doubt it is related with the permission not granted issue, is correct? Could any one can tell me how to get the permission granted? I used the debug.keystore, is that related? Thanks in advance!

[android-beginners] Why a static variay variable can not be released when executing finish() method to exit my application?
Hi guys, please see the subject. I define a variable like "public

class Main extends Activity{
Oncreate()
{
count++;
finish();
}
}
and then, when I running the app again, I found the value of count is
