I have a service that will monitor location changes daily. What I know so far that to start a service at boot, I have to follow the linked tutorial. This way I can get the service started at boot, but to save battery I need it only between 9am-9pm.
Question is pretty simple, so I will repeat:
How can I ensure a service is started at 9am and stopped 9pm every day?

View 3 Replies View RelatedI've a service which listens to user request for ending one activity and starting another activity. For Ex: Say there are activities1,2 ,& 3. Now if there is already activity1 started by someother activity then based on the user request i need to stop activity1 and start activity2 or activity3. If the acitivity1 is started by my service then i can do finishactivity(requestcode) and shall receive a call to onActivityResult() then i can start next activity 2 or 3. But can i stop the activity1 which is started by some other activity from a service?
View 2 Replies View RelatedI've successfully implemented a BootReceiver, AlarmManager, and Service per the code here: http://github.com/commonsguy/cw-advandroid/tree/master/SystemServices...
Inside the doWakefulWork method of the Service I am instantiating a few classes, but some of them require my Activity to be running. How do I actually start the Activity? The code above only starts the AlarmManager and Service.
There are also times where the Activity *is* already started, like if the user manually opened it. So I also need to start the Activity "only if it's not already running". Hows that work?
And what about the situation where the user first installs your application and may not even reboot their phone for a week. In that case, do you have to start the Service from the Activity? But then the Service will die with the Activity.
I am looking to code simple application
let's say I have an activity that starts a service which is simply a counter and counter value is reflected on activity UI , when I navigate away from this .I want this counter to be continue and when I get back to Activity I want to see counter count.so the question is
how can a reconnect with the started service and then if I want to kill it ? how can I know the service is already started?
I'm developing an Android application that consists of:
a lightweight background service that logs events to a DB
a heavier GUI application that summarizes these events and displays graphs.
I'm having trouble creating the service part, though. The graphic application can use quite some RAM, and when it goes to the background, the OS closes it after some time of not being used.
The problem is, when the application gets shut down, so does the service. This is bad because this keeps me from recording further events. I don't care if the application gets terminated, but the service needs to keep on running.
I have tried numerous ways to keep the service alive, like having it use threads or a differently named process than the main app. Nothing has worked, and I have found no help on any of the android developer pages or forums.
I start service by using:
private ServiceConnection _serviceConnection = new ServiceConnection() {...}
bindService(new Intent(this, MainService.class), _serviceConnection, Context.BIND_AUTO_CREATE);
I want to 'restart' the service. (Let's not argue why I want to do that)
I do that by:
unbindService(_serviceConnection);
// Do some initialization on service
bindService(new Intent(this, MainService.class), _serviceConnection, Context.BIND_AUTO_CREATE);
I noticed service doesn't die(onDestroy doesn't run) until I call next bindService();
So some static initialization I did on service got cleared by onDestroy() implementation.
Question: How do you make sure unbindService() will stop service (run onDestory()),
so that I could do initialization after and re-run bindService()?
When I do various operations on bluetooth application ... scanning, renaming and discoverable after some time non of these works... if I try to change name, it is not reflecting. is it problem with Activity/service? How to check whether these are still running? How to debug such cases?
View 2 Replies View RelatedMy Eris recently stopped getting 3G (or even 1x) service. When I try turning mobile network on it takes a long time like its searching then says it is on but when you go into "about phone" and look at mobile network it says it is not connected and there is no 3G or 1x display in the status bar. I am currently at school in the bay area and it worked for the first few days I was here, not sure exactly when it stopped cuz I mostly use wireless but noticed it when I wanted to do something off wireless. Pretty sure it is not a coverage issue because my friend with a moto droid gets 3G and it is almost as fast as his wireless connection at full bars. Also now I cant send or receive MMS due to this (apparently cant transmit over WiFi or voice signal), making my smart phone less useful than a dumb phone.

However, when a screen lock gets activated, the service is stopped (which is normal I've found out and I'm find with that). But when the screeen is unlocked again, the 10-minute interval could be already over and I want the service to do the job immediatelly. But... how can I detect that the service was awaken? I schedule the tasks with handler.postAtTime() method.

1) I want to ensure I am using a current 'fixed' location and not a previously stored one, so I am trying to avoid using getLastKnownLocation, but cannot seem to figure out the alternate to this?
2) What is the best way to display a "please wait" message or something along those lines while the GPS service is attempting to get a fix (and ideally periodically allow the user to cancel out)?

View 1 Replies View RelatedMy application opens in Activity A1. None of the views in A1 are focused at startup, until I use the arrow keys to navigate through the views. A button press in A1 launches activity A2. When A2 opens, the first Button in A2 is focused by default. I do not want this happen. What I want is when A2 opens, none of the buttons are focused until arrow keys are used to naviagte through them(just like it is in A1).

View 3 Replies View RelatedI open an Activity which has a number of elements... some TextViews, some Buttons, and an EditText. For some reason, when the activity starts, the EditText is focused by default, which causes the keypad to appear hiding the screen. I only want this EditText to be in focus if the user clicks into it. How can I ensure that this View isn't in focus when the activity starts? I've tried calling requestFocus() on one of the buttons, but it hasn't changed anything. Ideally, I don't want anything in focus at all.
View 7 Replies View Relatedi have a problem with double values i need to store in an android homed sqlite database. since these double values represent gps values (lat & lng), i really NEED an absolute precision down to the 9th number after the comma.when reading lng from this table into some (java) double variable, i get a value like "0.999956837" - this renders the values pretty useless to me.is there a way to enforce the precision i need other than storing the values as "text" fields (what would make expensive casts neccessary) or storing them as integers (meaning i need to multiply/divide at each write/read-op)?
View 2 Replies View Relatedi am using android.opengl.GLSurfaceView in my game, which is working well expect under one condition: Starting the game a second time after leaving it by pushing the home button, causes the game to flicker, because the rendering thread from the previous instance is still running and firing OpenGL commands. Now the question is, how can i ensure that only one instance of GLSurfaceView/GLSurfaceView.Renderer gets created?
To solve/workaround the problem i've tried to set the following properties in the manifest file to to ensure the activity gets shut down if it gets inactive.
android:configChanges="keyboardHidden|orientation"
android:launchMode="singleTask"
android:multiprocess="false"
android:noHistory="true">
But without success, the activity/rendering thread still keeps running. Do you know of any certain way to exit the rendering thread/free GLSurfaceView?
How do I ensure that I get the 'resize' behavior when the IME is shown/hidden?

View 2 Replies View RelatedHello all. I like to cut and splice my video files together to make one movie. I usually do this with Windows movie maker. That program doesn't recognize the .3gp format that the video files are in when I take them off the phone. So, I convert them to .avi. Is there a program that will ensure that the 720p quality is maintained through the conversion to .avi, or is there another format I should be converting them into? I can't remember the program I use now, but it doesn't look like it is staying in 720p quality. After making the complete video on windows movie maker I get an option to export the video in 720p, but if the input video is not 720p, the final output cannot be 720p right?

All my previous phones have just performed this function without needing any setting up, assuming the birthday is set in the contact.

Can someone please enlighten me on how I can ensure an alert is generated for these birthday reminders in the calendar?
