Just like the title says, Is there a simple line of code I could add to onStop()that will simply stop any gps activity currently going on with my application?

I have started dialer activity with code
Intent myIntent = new Intent(Intent.ACTION_CALL, Uri.parse(createTelUrl("1234567"))); startActivityForResult(myIntent);
Is there a way to stop the dialer activity from same code.? Logically it should be possible as i started it and i should have rights to stop it as well.
I need be able to tell if Activity.onStop() was called because my application is moving to a new activity, or if it was closed because the user pressed the "Home" key or hit the back button from the bottom of the activity stack.The reason is because I need to know when it is appropriate to shut off music that is playing in my application (A game). There is nothing more annoying than hitting home and having something playing music in the background.However, Activity.OnStop() is called for each activity change, and I don't want to suspend music when moving between multiple activities in my app. I just can't find a way to differentiate between going home and going to a internal activity.Am I perhaps hooking into the wrong events?
View 3 Replies View RelatedIn the Android Application Fundamentals it says that after the call to the onStart()-method of the activity lifecycle either the callback method Resume() or onStop() is called. In case of an "normal" Start of an activity the system calls onCreate(), onStart(), onResume().But does somebody know an example where onStart() - onStop() are executed one after another?
View 2 Replies View RelatedI'm having this strange issue where upon exiting a subactivity that is translucent (android:theme="@android: style/Theme.Translucent" ) the onStop() method doesn't appear to be called. have a TimerTask that runs and is supposed to be terminated when the subactivity ends in the onStop() method, but I'm instead left with an orphaned thread running in the background. It go particularly bad when I ran the subactivity several times. When I revert to no theme, the onStop() method is called and the activity behaves properly. Is there something I missed about how Translucent activities'lifecycles differ from standard activities?
View 4 Replies View RelatedI have a problem with the activity lifecycle specifically on Nexus One (2.1 running on emulator works fine). If I just create a simple empty Activity with no special launchModes that logs the calls on the onStart and onStop methods, this is what I see: - launch app: onStart called; - home button: onStop NOT called; - launch app: onStart NOT called; - home button: onStop NOT called: and so on. Sometimes if I press the back button then the onStop is not called, but the when i launch the activity again the onStart is called and right after the onStop is called. Similar results with different launchModes. What is going on? Can anyone confirm this?

I have an Android device where the default is for the Notification bar to be off so you cannot drag it down. I want to write a simple program that turns the notification bar back on so you can drag it down to view the notifications. If someone could show me the code to do that.

View 1 Replies View RelatedThere are apparently at least three different techniques for changing screen brightness in the Android OS. Two of them no longer work post-cupcake and the third accepted technique evidently has a bug. I would like to increase screen brightness at the start of a one-view activity then turn the brightness back to the user setting at the end of the activity. No buttons, no second view or second activity. Just a maxed brightness at start and a return to original brightness setting at the end of the activity. The examples of the current technique using WindowManager.LayoutParams that I have located range from 2 lines of code
WindowManager.LayoutParams lp = getWindow().getAttributes();
lp.screenBrightness = 100 / 100.0f;
getWindow().setAttributes(lp);
To several pages of source code and numerous activities. Is there a simple example of maxing the screen brightness at start that someone can provide a link to?
I have a basic calculator app I'm making. Two activities, the main one and ResultView.
I've made it where I click a button on activity A to go to activity B. The log says activity B is started and "displayed" successfully, the title for the new activity loads, but the body does NOT show. I added a simple Text view with static text.. see the result.xml at the bottom. I also tried inserting information programmatically, but that didn't do.
When I debug the program, I tried putting breakpoints as the activity is called with startActivity() as well as on the first line of the onCreate method within the ResultView class (my activity "B") but the program never hits the second breakpoint. In fact, it looks as if Looper.class is called in the end.
This bit of code is placed in the button handler on acitivity A:
CODE:........
The activity is in the manifest, within the "application" tag:
CODE:....................
If more info is needed, let me know...in short, "HELLO WORLD" does not display at all.
I am writing simple app that will read callLog content provider transform data and write it to my own table. my app will not show data directly from calllog content provider.
1. now one problem that I have is I cannot limit how much rows query will return (by calling activity.managedQuery) but I assume that Cursor delays access to the db and I can use moveToNext as many times as desired to get few rows from table and the call will be efficient. is that good thinking?? OR am I wrong here? I really dont want to query all rows from table. is there any other way to access calllog??
2. I dont want to implement my own content provider for my app. I will use rawQuery many times and group data so contentprovider's callbacks are not enough for me. more I want my dao to be private to my application so I think there is no need to bother with conentprovider. and If I got this right I also dont need to bother with activity.startManagingCursor as long I query data inside same method call (because I need to deactivate all intermediate Cursor objects anyway)
I am using a simple frame animation and when I exit and reenter my activity the activity is still referenced in memory.
//This is a sample activity I created to simulate the problem public class MemoryLeakActivity extends Activity {
@Override public void onCreate(final Bundle savedInstanceState) super.onCreate(savedInstanceState);
} @Override public boolean onKeyDown(final int keyCode, final KeyEvent event) {
final Intent i = new Intent(MemoryLeakActivity.this, LeakyActivy.class);
startActivity(i); return super.onKeyDown(keyCode, event);
} }
I have a simple activity program in android. Basically the class just extends Activity.
But when I start it I get a ClassCastException in the constructor of my class. I don't even have a constructor defined, so it must be in the constructor of the superclass which is Activity. Unfortunately the debugger doesn't give any detailed information on what class it is trying to cast. Here is the stacktrace:
Thread [<1> main] (Suspended (exception RuntimeException))
ActivityThread$PackageInfo.makeApplication(boolean, Instrumentation) line: 649

And when I look into this runtimeexception I get:

I have a very simple listview going on. The list just consists of strings, when you click the string it opens a new activity blah blah. Here's the problem, I enabled settextfilter and while it did filter the list, when you click the result, it always performs the action of the string located at zero, and not the one it is supposed to.

View 6 Replies View RelatedMy problem is: Activity A called Activity B, and in Activity B, it start a background thread to do some client-server work. But it maybe takes too much time. So i add a cancel button to call the stop() method to stop the thread, and call finish() to finish the Activity B and go back to Activity A. Although it is back to Activity A, the thread isn't stop immediately. Can i just call the finish() to go back to Activity A, and leave the thread to exit by itself? If it is not the right way, which is?

Currently working on a simple app to allow users to find various things around them. When the activity that shows the Google map is active I can see the GPS icon on the status bar, which is normal. But I need to be able to stop the GPS hardware when my user navigates away from the activity, and switch the GPS back on when the activity is shown.
Is there a simple way to stop GPS when a user navigate away from an activity? I have tried the LocationManager's removeUpdates() but this doesn't actually stop the GPS (the icon is still flashing on the status bar and draining the battery).
What I'm looking for is a simple way to programatically stop the GPS hardware.
