[android-beginners] Re: Programing Experience
Hi, For me it helped that am a professional Java developer that used Java and Eclipse every day for the last 3 years. The Eclipse IDE is easy to learn but suggest that you learn Java language first before trying to learn Android development. For Android there is the "Beginning Android" books that helped me a lot.

Hi Peter, Ya, by implementing some flags, I manage to see if I should call finish in the onPause state. Now my problem is resolved. Thanks.

[android-beginners] Re: Proper way to finish an activity
Peter, I read that before. But it still can't solve my problem in point 2. As if I call finish during onPause(), then I will have duplicate finish request complaint by the ActivityManager if user clicks on the button which will call finish() , and then the activity will enter into pause state and call finish() again. :( On Mar 31, 4:23 pm, Peter Fortuin wrote: > Hi DroidBy, > > Maybe it's a good idea to read the > following:http://developer.android.com/guide/topics/fundamentals.html#actlife > Read the part about the Activity lifecycle.

[android-beginners] google maps API: drawing and projection
Hi, The googlemaps API doc says something about Projection: "[...] public Projection getProjection() Get a projection for converting between screen-pixel coordinates and latitude/longitude coordinates. Returns: The Projection of the map in its current state. You should not hold on to this object for more than one draw, since the projection of the map could change. [...]" I have extended ItemizedOverlay to draw a set of markers on the map. Also, I have overriden the draw() method calling super.draw() and then drawing a path between each point where I draw a marker. Thing is that I exhausted the device with that method. The point is that on every draw() I get the projection of the view and I draw the path getting the pixel points with toPixels(). I have changed that to have an "old" projection and a "new" projection, and If they are differents projections then draw the path. I have a MapItem that has a GeoPoint, an OverlayItem, and some name or descriptions about it. His OverlayItem is added to the extended class of ItemizedOverlay. Then, the ItemizedOverlay is added to the Overlay list from mapView.getOverlays(). Is there a better idea to do this job? I think it's consuming too much CPU from the device (emulator). Without the old-projection-new-projection thing I managed to hang the Activity because it keeps drawing everytime the path. Another question, is it ok the if ( projection != oldProjection ) conditional to draw the path? Thanks for the help, -- If you want freedom, compile the source. Get gentoo.

[android-beginners] Re: How to save a file to res/raw ?
Great. This is what I wanted to know :) But, there's the next question. I'm still trying to create a custom soft keyboard. Therefore I need that xml - file. But how do I load my custom layout file into that ? I mean, the constructor only accepts an int ID. Like mQwertyKeyboard = new custom_keyboard(this, R.xml.qwert); If I try to put my xml file via FileReader or the like to the constructor, I get an error.

Re: [android-beginners] Re: screenOrientation question
Great, thanks for the info on rotating the emulator. That still doesn't really answer my question, but I think it suggests that it's an emulator bug. When using an HVGA-L screen on a 1.5 emulator, the application wrongly comes up in portrait (sideways) on the landscape device. When I switch the device, which actually makes it appear upside-down of what the skin should look like, the application rotates with it, staying portrait. I think it's just a bug of the way the emulator sees "landscape" on a device that's wide than it is tall... Thanks.

[android-beginners] Re: screenOrientation question
Hi You can simulate orientation changes by pressing CNTRL + F12 This allows you to test if your app remains in the correct orientation. Use the portrait mode emulator screen and then flip orientations to make sure it stays. But what you have in the manifest is correct. - On Mar 30, 12:50 pm, Chris Ross wrote: > I have written an application that really only works/looks sensibly in > landscape orientation, ie wider than it is tall.

When you run into that message, use adb logcat, DDMS, or the DDMS
perspective in Eclipse to examine your Java stack trace to see what the
exception was.
In this case, I believe it is a NullPointerException.

location will be null at this point, in all likelihood.

Sometime after you call this, getLastKnownLocation() will start working.
Until this point, though, the location provider may not be on and
collecting data.
Here is a sample application demonstrating obtaining your location via GPS:

[android-beginners] Re: List providers - does it work for Android 1.5?
Dear Andrian.
Thank you for your feed-back.
I keep on trying to understand List providers.
It should provide me a list of GPS satelitte from where I can read the
coordinates.
Unfortunately, providers is empty and hence my HTC Hero force me to
close it when running on the phone and reaches the line
GeoPoint p = new GeoPoint((int) (location.getLatitude() * 1E6),
(int) (location.getLongitude() * 1E6));
I have no problem in compilling the code.
Ideas are very welcome as well as code examples (I have inserted my
code below)
Thanks in advance.
protected void onResume() {
List providers;
super.onResume();
locationManager = (LocationManager)
getSystemService(Context.LOCATION_SERVICE);
providers = locationManager.getProviders(true);
if (!providers.isEmpty()) {
location = locationManager.getLastKnownLocation((String)
providers
.get(0));
locationManager.requestLocationUpdates((String)
providers.get(0),
15000, 1, this);
}
GeoPoint p = new GeoPoint((int) (location.getLatitude() * 1E6),
(int) (location.getLongitude() * 1E6));
mc.animateTo(p);
mc.setZoom(17);
mapView.setSatellite(true);
mapView.setStreetView(true);
mapView.invalidate();
}

[android-beginners] Proper way to finish an activity
I think someone here can anwer me.. I have an application with 3 activities, A, B and C. Three points here:- 1. In normal user sequence, activity A will start activity B, activity B will then start activity C. 2. In case, user is also allowed to cancel activity B (by a button), and it will resume back to activity A. 3. If activity B is interrupted by any application which comes into foreground, activity B should be killed and user should start from activity A if user navigate back to my application. In point 2, I have called finish() if user click on the button; In point 3, I have called finish in activity B onPause() function End up, I get an warning saying that I have duplicate finish request by Activity Manager as in point 2, the onPause() will be called also. So, does anyone here no how should I do in handling for point 2 so that I am able to resume to activity A after user cancels activity B? Or how should I do in case to stop my activity B so that user always start from activity A? Any best advise here? -- You received this message because you are subscribed to the Google Groups "Android Beginners" group. NEW!
