Re: [android-beginners] Re: onDestroy() caused "application stopped unexpectedly"
Any particular reason you are using System.exit() as opposed to finish()??? finish() gives Android the opportunity to do any cleanup that it needs to when your app gets done... I would imaging that System.exit() bypasses this. -- There are only 10 types of people in the world...

Thanks Justin and TreKing! I haven't found the error for onDestroy after looking at the log but I've managed to close the application using JAVA System.exit() instead. It does stop retrieving GPS signals after I exit the app. On Jan 7, 2:20 am, TreKing wrote: > > BTW, if i change onDestroy() to finish(), the application works fine so > > other parts should have no problem.

[android-beginners] Re: Problem with Custom Dialog
Hi Treking,
I have tried as you have suggested but not able to get the value.
May be i missing something.
Here is my code:
public class GetDialog extends Activity
{
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button valueButton = (Button) findViewById(R.id.viewButton);
valueButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
showDialog(0);
}
});
}
protected Dialog onCreateDialog(int id) {
LayoutInflater factory = LayoutInflater.from(this);
final View textEntryView = factory.inflate
(R.layout.viewlayout, null);
return new AlertDialog.Builder(this)
.setIcon(R.drawable.view)
.setTitle("Enter Value")
.setView(textEntryView)
.setPositiveButton("OK", new
DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int
whichButton) {
EditText valueText = (EditText) findViewById
(R.id.viewText);
getvalue(valueText );
}
})
.setNegativeButton("Cancel", new
DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int
whichButton) {
}
})
.create();
}
void getvalue(EditText val)
{
try{
String value= val.getText().toString();
Log.i("Value ",value);
}catch(Exception e){
Log.i("Error", e.toString() );
}
}
}
It gives me error as: Java.lang.NullPointerException
please suggest.
Thanks

Re: [android-beginners] Re: Databases in Android
I've only read a little bit about the DB.. is it possible to create/store on on the SD card? If we're limited to 24MB ram, 16MB on older devices, does that restrict the amount of data a DB can store as well? Seems it should be possible to put the DB on the SD card.

Thanks, you are of curse correct...I was being lazy. I did try the postDelay and that helped a bit but not as much as I need. My layout is really super complicated too..is it possible some of the time is stuck unwinding that? Is it possible to load a different, less complicated layout then overlay it with the final one... Without the layout sliding away and the new one sliding in?

Re: [android-beginners] launch an activity right into the background
I assume this carries on from your earlier question about delaying tasks in an onCreate()? It is technically possible to move your intensive code into a "Service" and have it start when the phone boots up, but bear in mind that this is an unpopular method, as users will find their phones become sluggish whilst your app does all it's processing work in the background. My recommendation is to try and optimise your app a bit better. Otherwise you will get low ratings on the market and lots of refunds (if you plan to sell it). Some suggestions: - Take a look at some of the suggestions on your previous thread - Use a progress dialog when slow loading operations are occurring (it makes a BIG difference when the user can see that something is busy) - Delay some of your processing until the user does something (like clicking on a tab) - Cache some of your processed data, either in a database or a file, so you don't have as much to do the next time the app is loaded There are plenty of other things you can do, some thought and research should . Really, launching stuff in the background should be avoided as much as possible, mobile devices have very limited resources and your app will have a negative impact on the phone's responsiveness.

[android-beginners] launch an activity right into the background
Can I launch an activity and have it go strait into the background without the user seeing it, until they select to launch it themselves? Basically I have an application that takes a long time to start the first time, but is super snappy after that. -Mike -- You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] Re: problem with adb
1. Windows7 2. Eclipse & android were installed in C;\dirname of software pkg. 3. Got it to fire up, but the emulator does not pick up the pkg I'm trying to debug. And if you just right click on that pkg and say run/debug, that's when that error comes up. But if you go 2 preferences and click on the android portion. That's where u see android versions then u can select one/or create a new one(those do work, but the pkg fails to show up on the emulator). This is a copy of my other laptop, and all works fine on that one. Plus, it isn't finding some of the software that is on the system that is in the path.

Re: [android-beginners] Re: How can I make a vew show up really, really fast?
The method really depends on your requirements: * If the amount of work isn't too great, and you just want the activity to be drawn before the processing starts, then postDelayed() is a sensible approach. * If you have a lot of processing to do, and the execution needs to be linear (e.g. (a) must finish before (b) which must finish before (c)) , then an ASyncTask or Runnable would allow that to happen without interfering with the activity event loop. * If you have a lot of processing to do, but want to split it up into lots of asynchronous background tasks (and execution order is less of an issue), then using a message queue would be more manageable. If you're unsure which one you will need, then a postDelayed() is a simple approach to start off with. You could extract intensive work into background threads later on.

[android-beginners] Need Help : canvas.drawtext() for a lengthy string
Hi All
I am stuck in a very simple problem.
I have one lengthy string & I need to draw that on the device display.
My code is as follows:
void ShowText(String text) {
canv = thread.mSurfaceHolder.lockCanvas();
if (text!= null) {
canv.drawColor(Color.WHITE); //background color
mPaint.setColor(Color.BLACK); //font color
mPaint.setTextSize(15); //font size
canv.drawText(text, 10, 200, mPaint);
//startign at some
(10,200) coordinates , dratext
}
unlockCanvasAndPost(canv);
}
But the problem here is, the string is going out of the screen. I want
it to break down into multiple lines if it is too big for the screen
width.
Can anybody show me some example to do this?
Thanks
Latha
