View 5 Replies View RelatedAndroid :: Android Permissions - Calls Read Phone State / Identity?
Nov 17, 2009My android app has nothing to do with phone calls, but I'm seeing that when I install a debug build on my test device it requires "Phone Calls: read phone state and identity" permissions. (I make no mention of this in AndroidManifest.xml). I'd like to have the minimum possible permissions, and wondered if anyone knew how to get rid of this? I commented out the part where I was logging some stuff from Build.MODEL, Build.VERSION.*, etc. I also commented out the part where I was detecting the landscape/portrait orientation thinking that that might be the "phone state". But neither of those seemed to remove that permission required.
I found this bug report but it's marked working-as-intended with a note about permissions being correct from the market but not otherwise. Is this other people's experience? (I'd hate to have to publish to the market just to test that out.) Otherwise, does anyone know if there's an API I can avoid calling that will make it so my app doesn't need this permission?
Android :: Changing Displayed State Of Views Based On Parent ViewGroup's State
Aug 11, 2010I have a compound UI component built up from a ViewGroup containing a number of TextView, ImageView etc. components. Many of these have StateListDrawables as their images/backgrounds. Is there any way of making them select from this drawable based on the state of the parent ViewGroup rather than the component itself? Ideally I want to be able to change the visual state of all children of the ViewGroup (text colour, image etc) based on the state of the ViewGroup, preferably without having to hook up complex logical code. This seems like a fairly common sort of requirement, so I was hoping it would be straightforward in Android - am I going to be disappointed?
View 1 Replies View RelatedAndroid :: Phone State Listener State Transitions
Feb 8, 2009I'm a little confused by what I'm seeing with regards to phone state transitions via the PhoneStateListener. When I receive a call, this is what happens: (call comes in) RINGING -> IDLE (I pick up) OFFHOOK (I hang up) IDLE It's that first transition from RINGING to IDLE without any interaction from me (not ending the call, not answering the call) that confuses me. Do I really have to implement an idle counter to know that an incoming call has really ended? Seems like the reported phone state represents some sort of phone state that isn't the obvious one.Is this a bug or am I just not in tune with the paradigm here?

Oct 6, 2010I know this has most likely been discussed many times. But I am looking for a decent email widget.
At the moment I am using the default htc email widget, however when ever I read an email from my gmail account it doesnt update the read status so it still shows as unread.

Android :: Screen On/Off State?
Nov 3, 2009I have an app that runs in the background indefinitely provided there is work to be done. I want the app to go to sleep if there is no work to be done and the user is idle. The second part has me stumped. On Windows Mobile I was able to poll the power state to determine user idleness. On BlackBerry I was able to poll the device idle time. However, there does not appear to be a way to determine user idleness on Android.
Instead of polling for user idleness directly, I thought I might be able to use the on/off state of the screen. There are 2 intents ACTION_SCREEN_OFF and ACTION_SCREEN_ON and I was able to setup a listener for these (BroadcastReceiver). The problem is that I do not know how to determine the current state of the screen at the time I register the listener, therefore I have to wait until the next screen on/off change to know anything. The docs speak of some intents that are "sticky" and thus will allow the current state to be determined, but the screen events do not appear to have that property. What am I to do?
In general, I find the lack of support for polling system state properties (e.g. screen state, power state, signal strength) in Android to be annoying. It's cool that one can listen for changes in system state rather than constantly polling for them, but one still needs to know the current state of the property at the time the listener is registered.
Android :: Restore Instance State
Aug 24, 2010I need to save some state when the user leaves my game during game play. Saving the state doesn't seem to be an issue, but I can't figure out how to restore it. The onCreate function isn't called when the Activity is resumed (only when it is first created), so I can't get my state back there. Logically, I would use onRestoreInstanceState, but it isn't being called.
CODE:..........
I see log output from onSaveInstanceState, onResume, onCreate, etc, but I never see a log message from onRestoreInstanceState and savedState is always null. Why isn't onRestoreInstanceState being called, and is there another way to get my state back?
Android :: Usability / State Vs Verb?
Feb 26, 2010My business partner and I have a small disagreement, and I'm trying to figure out the best way to resolve it. First, I should say I started out his way, and switched after reviewing a lot of applications. The background is this -- we have an app, with some controls which can be locked. A lock/unlock icon is put next to the lockable controls. You can long-click the icon, and it brings up a context menu with several items, including the item for the lock state.Currently, it brings up a "Locked [X]" or "Locked [ ]" item -- that is, a menu item with a checkbox that can be checked or unchecked, and the lock state is changed accordingly.He would like me to change it to reflect the action being taken. I.e. the menu item would say "Lock" if it is currently unlocked, and "Unlock" if it is currently locked.It would be acting as a toggle in either case; the only difference is how it is presented to the user.

Aug 30, 2010I am writing an app where I get all the data from the rest call and display all the data in a custom component list(based on Linear Layout) which is added to a LinearLayout. I write this code in onCreate of the activity. The problem is when I switch activity using startActivity, and come back to the calling activity (using startActivity) then onCreate is called again. I see onPause, onStop called when I call other activity. Is there any way that I can save the application's state?
View 1 Replies View RelatedAndroid :: How To Get Pressed State Of Preference
Sep 10, 2009There is know problem in all the Android phones. Go to Bluetooth Settings->Turn ON bluetooth->Click on bluetooth discovery->Then timer will start in summary->Long press on Bluetooth device discovery-> observe Bluetooth ON/OFF title start to toggle with Bluetooth Discovery toggle. I analyzed the issue. Blueooth ON/OFF is CheckBoxPreference. Bluetooth Discovery is also CheckBoxPreference which has dependency on Bluetooth ON/OFF. When we click on Bluetooth discovery then On thread will run at every second to update summary in Bluetooth Discovery preference. When we change the Bluetooth discovery to OFF then thread will be removed/ killed. When i press the Bluetooth discovery for long time when its already in ON State then still the thread will be updating the summary (remaining time from 120 to 00) till i press it. When i leave the Thread will stop. As it has dependency on Bluetooth ON/OFF, its making to the title invisible. But it should not happen. Solution: When i touch the Device Discovery i should kill the update summary thread then i guess, that problem will be solved. But in prefence i dont have any listener to know the pressed state. I hope somebody can give me solution.
View 2 Replies View RelatedAndroid :: Saving Application State?
Jan 11, 2010I understand how to save an application's state by using SharedPreferences, onSavedInstanceState() & onRestoreInstanceState(), etc as outlined in a similar post ( http://stackoverflow.com/questions/151777/how-do-i-save-an-android-applications-state ), but how do I save the last activity?
To be more specific, my application starts up and goes to a login screen. Once a user logs in and navigates through several activities, lets say he or she leaves the app using the home button or in some other way. Next time the user starts the app, it will go back to the login screen and do a login again. Instead, I want the app to start up and go to the last activity that was on top of the stack when the user left the app in the previous session.
How is the last activity saved so that it can be restored on app startup?
Android :: Get Current Sensor State?
Feb 7, 2010Yes, I can get sensor update events with SensorEventListener. But this approach has 2 drwwbacks:
1) For some sensors I have to wait for the state to update. For example, temperature may update after a minute!
2) In some cases I can get incorrect readings. For example, the phone lies on a flat surface and does not move. I receive first orientation update event after listener registration. When only a part of the orientation vector changes, other parts may be 0. And it is no way to determine, is it a true 0 degree azimuth or just an incomplete vector. If I move the phone a little, the correct non-zero azimuth appears.
To solve this problems it's possible to create a separate thread that constantly monitors sensors. After some time it will certainly contain true values. But I think that it is an overhead for such simple task.
Is it any other way to get current sensor data?
Android :: ImageButton With A Selected State?
Apr 9, 2010If I was using an ImageButton with a selector for its background, is there a state I can change which will make it change its appearance?

Here's my XML, it only changes appearance when pressed.

Android :: Saving And Restoring State?
Jul 15, 2010I have searched through this and a few other sites for the answer, but I have been unable to find it. I am trying to save a boolean and an int using onSaveInstanceState and onRestoreInstanceState, but I can't seem to get it to work. It doesn't crash or anything, but it either isn't saving it or it isn't restoring it, or I am stupid and have no idea what I am doing.
Here is what I have for my activity, do I need to have it in my onCreate somewhere or something?
CODE:..............
I tried putting stuff in the onStop, but it crashes, which is why its empty, in case that matters, thanks in advance

Aug 9, 2010I've encountered a problem wile using my own subclass of android.app.Application. I have numerous activities in my application and I'm running a custom ROM which consumes quite a lot of memory. What happens is when I launch a third party activity (Camera) my Application is killed. My Application subclass stores vital data for the whole app so it can't work without it. android.app.Application doesn't have any methods for saving or restoring application state. Activity does have them but they are not suitable.
How to perform save/restore state on Application subclass?
UPDATE I've managed to do so by filling a Bundle obtained from onSaveInstanceState and restoring values in onCreate. But is there any better way?
