May 16, 2010

Intent i = new Intent();
i.putExtra("updateInterval", 10);
i.setClassName("com.blah", "com.blah.S");
startService(i);
A have a function like this one in A: public void someInfoArrived(Info i) Now I want to call A.someInfoArrived(i) from within S. Intent.putExtra has no version where I could pass an Object reference etc.

Whenever the memory needs to be reclaimed, the process is being killed by Activity Manager Service in killPidsForProcess. I have a back button in my activity window on right corner of the title bar.
I want to kill the activity completely on clicking the close button. Can I reuse the same function and will it have any major effect? Please help me out in this.

say for example I have this code in my activity:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Thread cThread = new Thread(new Runner());
cThread.start();
}
private NotifyMe(){
//do something here
}
and this is my Runner class:
public class TCPClient implements Runnable {
public void run(){
//call NotifyMe() [THIS IS MY QUESTION]
}
}
I have a thread on my activity that runs the Runner Class. Once the thread start, I would like to call the NotifyMe() function that is located at the activity. Is this possible?

I would like to compile a list of Android phones that either
1) Comes with native call recording functionality.
2) Support call recording with 3rd party applications.
It would be great if you can lend a hand.Please note that phone/apps that require using speakerphone to record the calls do *not* count. That's a ugly hack I consider marginally useful.Please don't bring legality discussions here as well.Models that have this function built-in.Samsung Galaxy S (South Korean version SHW-M110S, with firmware DH09 or newer).Models that don't have this function built-in but can use 3rd party app to record calls in both ways without turning on speakerphone.HTC Magic (a.k.a. G2); requires root and custom kernel; with rViox

It's possible to specify a particular function to be called when button is clicked by setting its onClick attribute in xml:
android:onClick="function_name"
I want to do something similar for FocusChange of buttons, is this possible?
Specifically, I wish to increase my button's size when it has focus and make it normal sized when not focussed. To apply this to all my buttons, I hoped to call a specific function which does this and then specify this function name in my style.xml. But there is no onFocusChange attribute in android.
It works when I add overriden onSetFocusChangeListener for each of my buttons separately in the code. But is there any other solution?

public class CardsActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
I could not find the place where onCreate() is called, I want to know where savedInstanceState is passed over to public void onCreate(Bundle savedInstanceState).

I've implemented an onSaveInstanceState function in the main activity of my TabHost-based application. I need to save the state of various objects I am keeping in memory that I have all marked as serializable, as well as some basic int and string values. I have stepped through my application and watched it call the onSaveInstanceState function and presumably save everything without any manner of exception or problem. The issue is that my onCreate function is being called with a null Bundle value every time after I start the application again. I'm really at a loss and unsure why it would call the save but not pass anything into the create.

I'm developing a GPS tracking software on android. I need IPC to control the service from different activities. So I decide to develop a remote service with AIDL.This wasn't a big problem but now it's always running into the methods of the interface and not into those of my service class. Maybe someone could help me?If i now try to call a method from an activity for example start(trackId) nothing happens. The binding is OK. When debugging it always runs into the startTracking() in the generated ITrackingServiceRemote.java file and not into my TrackingService class. Where is the problem? I can't find anything wrong.

My point is to be able to call a 2.1 API if it exists, while the application should be able to run in 1.5
Specifically, I am making a GPS application which would like to call android.location.LocationManager.addNmeaListener if available. My problem is that this call takes as parameter an abstract class (GpsStatus.NmeaListener) which I cannot pass directly to Class.GetMethod (or my application won't work in 1.5). What I am currently trying is a) to create a wrapper class for GpsStatus.NmeaListener:......................

I've noticed with my T-Mobile G2 that there is no call waiting alert with the default settings, so I'm never aware of someone trying to ring me from within another call - a function that's been standard on every other mobile I've used.
I'm sure it must be possible to set this up, but can't seem to find out how to do it. Very annoying, as I invariably get calls on top of one another and people are starting to tell me they're sick of being put through to my voicemail.
