I have built an application that listen to call state changes, and I want to notify a service when the call_state became IDLE.All the components I have are functional, I just need to notify (not start) a service for this.What's the correct practice, maybe using AIDL? Because, in a PhoneStateListener, I can't bind to a service. Do I have to start an activity for that?

I have a BroadcastReceiver that listens for the BOOT_COMPLETED, that part works I know because I disabled my phone listener and displayed a Toast within. That BroadcastReceiver is supposed to start a service, that also works. I run into Force Close issues when my service attempts to tell my TelephonyManager to listen. Any one have any ideas? Here is my code StartSeviceAtStartUp.java import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent;
View 3 Replies View RelatedI'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?
View 2 Replies View RelatedThere appears to be a leak when using PhoneStateListeners. The following code simply reigsters in onResume and unregisters in onPause a PhoneStateListener. Repeatedly launch then press BACK (so the app is finished & onDestory is called before the next launch) and the number of activities reported by meminfo will equal the number of launches. For instance, here is the output I get after launching (and finishing) 11 times in sequence:

Without the PhoneStateListener, the number of activities is always 1 no matter how many times the app is launched & finished. So, am I doing anything wrong here? Or is this a bug in the TelephonyManager?
Here's the code package com.example.leak;
import android.app.Activity; import android.content.Context; import android.os.Bundle; import android.telephony.PhoneStateListener; import android.telephony.TelephonyManager; import android.util.Log;
public class LeakExample extends Activity {
private class MyPhoneStateListener extends PhoneStateListener {
@Override public void onCallStateChanged(int state, String incomingNumber) {
if ((state == TelephonyManager.CALL_STATE_RINGING)
|| (state == TelephonyManager.CALL_STATE_OFFHOOK)) {
LeakExample.this.finish();
} } }
MyPhoneStateListener phone_listener = new MyPhoneStateListener();
TelephonyManager telMgr ;
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
telMgr = (TelephonyManager) getSystemService (Context.TELEPHONY_SERVICE);
} @Override protected void onPause() { super.onPause();
telMgr.listen(phone_listener, PhoneStateListener.LISTEN_NONE);
} @Override protected void onResume() { super.onResume();
telMgr.listen(phone_listener, PhoneStateListener.LISTEN_CALL_STATE);
} @Override protected void onDestroy() { super.onDestroy();
Log.v("LEAK EXAMPLE", "onDestory");
}
I would like to know what are the main differences between TelephonyManager and PhoneStateListener, because you can do (more or less) the same things with both. For example, you could create an incoming calls register implementing a broadcastreceiver and using TelephonyManger API or extending PhoneStateListener class and registering this new listener throughTelephonyManager . Case 1 - BroadcastReceiver (TelephonyManager)
View 13 Replies View Relatedi've registered a PhoneStateListener in BOOT_COMPLETED receiver by using following call: tm.listen(new TestCallStateListener(), PhoneStateListener. LISTEN_ CALL _STATE); If the application crashes then system automatically unregisters the PhoneStateListener. Is there any mechanism of checking if particular PhoneStateLister is registered or not? Actually i'm thinking of starting a repeating service by AlarmManager which will check if PhoneStateListener is registered or not . And if it's not registered then service will register it again. Just a backup if application crashes. Is this a good approach or there is some better mechanism to make sure that PhoneStateListener is always registered even if application crashes ?
View 2 Replies View RelatedMy application process incoming/outgoing calls and shows some UI. So I use PhoneState Listener to listen changes such as CALL_STATE_IDLE , CALL_STATE_RINGING ,CALL_ STATE_ OFFHOOK. on receiving call to my BroacastReceiver for incoming/outgoing call. Most of the time things work properly. But sometimes my application does not receive events of Phone State Listener and hence it is not able to change/clear UI.From user feedback this typically occurs on HTC Hero. But I have came across this issue sometime on other devices also.My first guess is that android is killing my application in midway during call due to memory requirement. If so, is there any way to ensure that android does not my kill application under such situation .
View 1 Replies View RelatedI have a background service application that get informations through a web service. This service has to alert the user when it gets some abnormal values. I also have a UI application that is used to display these informations. Finally, the only way I found to be able to get the service and the UI application to share these informations, was to create a third application that defines a custom ContentProvider . I've tried to define the ContentProvider in the service application to have only two applications, but it didn't worked. Everything is fine with three applications.
For CPU and battery saving reasons, the background service is refreshing the informations each 5 minutes. But, the UI application needs to refresh faster than 5 minutes. So, when the UI application starts, I need it to notify the background service to start refreshing at a much faster rate. And, obviously, when it closes, the background service needs to get back to the normal refresh rate.
My problem is that I don't know how to notify the background service from the UI application. I can set a field in the database when the UI application opens and closes, and check that field every second in the background service, but it will kill the CPU and the battery! How can I set some listener in the background service and send and event in the UI application. Can I define custom Broadcast events?
Is there a way to notify an activity/service of a force-close request right before it gets killed?

I have a galaxy s2 and after I installed costom roms I dont have any signal what so ever.
I tried with like 3 roms and the same result.
I tought it was a modem problem and I tried to install some modems and see if that works. But it didnt.
My Service State says Out of service and sometimes it says Radio off.
I just want to develop a service which listens to the database and it should invoke an activity as soon as there is a change. I tried to implement Contacts listener by registering Content Observer but couldn't see the expected result. Kept log in on Change() method, observed that it is not getting called, any clue that where it might went wrong.

View 2 Replies View RelatedHere's my Python script written using android-scripting:
CODE:............
while True:
CODE:.............
It basically vibrates every minute (like a motivator). However, when the phone is locked with screen blanked out, I don't sense any vibration. Perhaps Android is freezing the script (and hence the while loop)? Note that I am indeed running this script as a service (long-tap and click 'Start as service').
Is there a way to make this script work all the time regardless of the phone suspend state?
Update 1: I do hear the vibration occasionally, not every minute .. but rather like every 5-10 minutes randomly.
Update 2: This problems occurs if I run the script normally (not as a service). Seems like "time.sleep" is not sleeping for the specified time.
I wonder if it's possible to get music player state, like which is the current music playing, title, author and so on ? Better, is it possible for an activity (or a service) to be notified on music state changements (start playing, pause, etc.)
View 3 Replies View RelatedI have a Service which tracks the location of the user. Currently, the Service boots when the application starts and stops when the application terminates. Unfortunately, if users keep the application in the background, the Service never stops and drains battery.
I would like the Service to stop when my application is not in the foreground. I was hoping the Application class would let me Override onPause and onResume handlers, but it does not have them.
I want to send an intent to my service everytime the state of Wifi connectivity changes.

What is the best calendar app? Is there a calendar app or an addon app that will utilize the alarm in the phone to notify you of upcoming meetings? So far all i can find is ways to email or sms meeting warnings. The incoming sms doesn't get enough attention.
View 1 Replies View RelatedHey, I was playing around with my Incredible today, and to my dismay I have made it so my phone does not vibrate when I receive text messages.
I looked through all the other threads and they didn't help.
I've gone through the sms settings and turned vibration "on"
I even have it in vibrate mode. that didn't work.
regular mode. didn't work.
I fixed it just in case anyone else runs into this problem:
Download "sound manager" open the app, click your "menu" button and click "vibrate options"
You'll see that vibration notifications are turned off.
I 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?

I was trying to root my samsng behold 2 earlier today using the command codes on theunlockr.com. I thought everything was going well as I went all the way to the last step where it rebooted my behold 2. Problem is, the phone kinda just turned off after doing the reboot command and didn't turn back on by itself (I gave it like 10 minutes). I eventually then just turned on the phone manually and noticed that everything was super laggy. Even when I used taskkiller to kill every task minus GDE, it said I only had 38MB ram available. I rebooted my phone a few times and it was laggy everytime so I decided to do a hard reset. The problem is that when I attempted the hard-reset, it will now get stuck on the samsung screen when trying to load up (stayed there for over 30 minutes). I can still enter the phone if I just start it up regularly without trying to hard-reset, but it will continue to be VERY laggy.
Is there anything I can do to restore this phone back to its original state? I was reading about using ODIN to flash it or something, but for some reason my computer doesn't detect my phone when I go into Download mode on startup (it does however detect the usb drivers on my phone once the phone officially startsup into its homepage).
