I have android app using google maps API. When the app is running and user doesn't interract with it app still works and system doesn't go to sleep. However I need to close it if user doesn't interract with app some while. Is there any solutions?
There are a lot of posts regarding this topic already. A key point is that the OS handles this for you and it isn't necessary to force this behavior. If you really want to force it you could have a scheduler in your application triggered by the onStop() method. When the scheduled task executes you can then call one of the functions mentioned in the links provided below to kill the app.
How to quit android application programmatically
A timer that will kill android app after idle for certain time?
I was developing an app for an enterprise which has given the employees an android phone, they wanna monitor every time a user tries to open any other app and send a report to a manager so I´ve developed an android service that checks every time any other app is call meaning: OnCreate, onResume, etc.(that´s done) Now they wanna check what that particular user did once he got into the other app: for example if he opened the messages(com.android.mms) , what message he sent or what he had recieve. other example: if he opened the dialer(com.android.dialer) they wanna know what phone he called. What makes it tricky for me, is that they want this for EVERY POSSIBLE APP a user can have installed in their phone.
My Question is the following: is there a way to capture this kind of information of a running app, from a service?
I appreciate any answer and I´m open to suggestions of how should i do this.
I'm facing the following problem. I want to make an android device to run only my application. All other apps and phone feautes should not be available to a user.
The reason why I want to achieve this is simple: I want to destribute devices with preinstalled application to my client but I don't want to let them use all phone featues.
This could work this way: just after android boots my application is launched automatically and than somehow all other staff is blocked.
Do you have any suggestions how to achieve that? Is it possible? Do I need to root a device?
I hope you get my problem. Any advice you can give will be greatly appreciated.
This is a bit crude way. But see if it is of any help.
If you create your application as a launcher it will start on boot(using system broadcast BOOT_COMPLETED).
Then you need to override all the three android buttons Home, back and recent apps.
To override back button you just have to override the onBackPressed() method.
For home button you will start a service which will run in background. This service will check if your app is in foreground or not. if not then it will bring it in foreground. so when the user presses home the service will sense the foreground app isnt yours and launch it.
But for this switching back of your app android takes approx 3 to 5sec. In that period of time you can display a warning text which will block the user from stopping the service from settings.Also if you remove the activity animations then it will appear seamless.
For recent apps button the above trick will do. If the user tries to close the app using this button your background service will sense it and launch your app.
so its the background service that does all the trick. if you some how stop the service or uninstall the app you are through :p
I am writing a metronome app, I have the sound running from a service which I would like to keep running when the user is outside the app (browsing etc) and hasn't made a conscious effort to press the stop button.
It seems I should be using startForeground() as it's not the kind of thing you want in the background without paying attention to, and I really don't want the service to be killed at any time. Ideally I wouldn't be showing the notification while the app is in focus though. I notice that the Google Play Music app works this way, it only shows the notification when outside the app. Is anyone able to tell me how they have done this, I would find it hard to believe they wouldn't be using startForeground() after reading all the documentation stating you should be using it for this sort of app?
On the other hand, is this really desired behavior? It seems good to me, but I noticed that pretty much every other app I use with a long running service (HTC's music app, Navigation, few others) shows the notification icon at all times, whether in the app or not. I am interested in what is considered correct behavior. Any help much appreciated, thanks.
Is anyone able to tell me how they have done this
They probably call stopForeground() when one of their activities returns to the foreground, and startForeground() when they think the user has left (e.g., onUserLeaveHint()).
I am interested in what is considered correct behavior.
I do not think there is a definitive "correct behavior" in this area. It is easier to do what the other apps do and leave the Notification around, until the user indicates that they no longer want the background work to run.
Note that while you may want "to keep running when the user is outside the app", the user might not. Certain types of apps (e.g., music players) can safely assume that the user wants the audio to keep going; a metronome, IMHO, does not rise to that level. Please allow the user to configure this behavior, such as through a SharedPreference.
Hello I want to log application activity information on my android phone, I just need 2 things, the start time of the application and the end time of the application.
I just want to know for how much time a particular application/activity was running.
Say for example a user launched music player and after some time closed it? I just want to know how long the music player opened, or if he is talking on phone how long that activity to took after finishing?
My application will run as service, logging all this information is sqlLite. Once my application started it should log all the above information for each activity triggered there after.
Please let me know how can i do this??
I know about logcat but i want to know how they log this things or how can i code something similar??
Thanks
