I can see that we can get a phonestate via the PhoneStateListener, but there is no way of telling the state of the call. OFFHOOK is a number of states combined into one. Is there a particular reason for this? Are we not allowed to see the correct state of a call?

I have an Activity, which contains a bunch of check boxes and a submit button.
When the submit button is clicked, the activity will exit (finish() will be called). Before the activity exits, I want to save the states of the check boxes in the activity, so when the activity starts again, the check boxes can stay in their previous states. What's the correct way to save these states? Should I use SharedPreference.
I have a gallery that displays TextViews where the background of each view is the following code...
This selector work just fine for the state_pressed and default (idle) states, but the selected item state is never displayed. I REALLY do not want to force the background of the selected item by changing the background of the view when the onItemSelected event is called. What is the correct state or correct way to get the TextView background to be set properly. Is the selected (center) view in the gallery not really selected? Is there some other state I should put in the selector drawable xml?
I just read from internet to maintain the state of my application by overriding the onKeyDown function as given below. And set the launch mode of my activity as singleInstance. And it is working perfectly. Just want to know if it is correct approach. And how it is different from onSaveInstanceState.

I tried PhoneStateListener but not working.
I'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 RelatedI got one question regarding the intent action "ACTION_CALL". What is the correct way of getting back to the own application/activity after the user ends the call? The only way that came to my mind uses a PhoneStateListener in a background services that waits for the CALL_STATE_IDLE event starting up the application again. But I am not quite sure if that is the correct/intended way of using the intent.

View 2 Replies View RelatedI am writing a service which listens an incoming call. I have a function but it behaves differently under these cases when i call the function in case case Telephony Manager . CALL _STATE_OFFHOOK: it works! when I call the same function in case case Telephony Manager. CALL _STATE_RINGING: it doesnt work. it seems that when an incoming call happens the system blocks some components. what should I do to prevent from this situation. Should I move my calculation to a background thread? Does it work in that way?
View 3 Replies View RelatedI 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 2 Replies View RelatedI'm writing a live wallpaper, and I'm forking off two separate threads in my main wallpaper service. One updates, and the other draws. I was under the impression that once you call thread.start(), it took care of everything for you, but after some trial and error, it seems that if I want my update and draw threads to keep running, I have to manually keep calling their run() methods? In other words, instead of calling start() on both threads and forgetting, I have to manually set up a delayed handler event that calls thread.run() on both the update and draw threads every 16 milliseconds. Is this the correct way of having a long running thread?
Also, to kill threads, I'm just setting them to be daemons, then nulling them out. Is this method ok? Most examples I see use some sort of join() / interrupt() in a while loop. I don't understand that one...
I 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 RelatedI was just working on an application that will do stuff when a call is missed or made; and am left wondering why do you have to register a listener using a long lived background service for phone state changes instead of being able to use broadcast intents?

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).
There 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");
}
Anyone know what providing an application access to "Phone calls: read phone state and identity" actually does?
View 5 Replies View RelatedI 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 2 Replies View RelatedI am trying to save some values in the onSaveInstanceState(Bundle) method of my activty by following the example here: How do I save an Android application's state?
But it doesnt seem to load it from the Oncreate(). the bundle object is always null but whenever i call another activity, it does indeed go into the onSaveInstanceState method to save my values.
Now i read that question i just posted and someone noted how they could not get it to work in an emulator? unfortunately that is all im working on. On an emulator and cant test the app on the device as i have no device available to me right now And the web services i am interacting with are in a local VM on my work machine that cannot be accesses remotely at the moment.
My question is, is it true that saved bundles dont work on emulators? I also noticed how when i do dismiss or bring up a new activity , the activity calles onPause and then onStop. when i bring back the same activty, it goes straight to onCreate?
now according to the docs here http://developer.android.com/guide/topics/fundamentals.html#actlife That is correct in terms of what the lifecycle diagram shows but if you read below that diagram on the onStop() section it says the next step it goes into is either onRestart() or onDestroy()? no mention of onCreate? Type on the docs?
Anyways here is my onSaveInstanceState() and onCreate() both in the same activity: code...
I have 3 questions about Visual Voicemail in the Incredible.
1. Is the Visual Voicemail that's in the phone the correct one, or do I need to download the app? It seems when I get a Visual Voicemail, it is showing up in with my text messages. Is that how it's supposed to work or is there supposed to be a separate app?
2. Is it just me, or do people who leave messages sound mechanical? The few voicemails that I've received so far sound terrible. They sound like their voices are synthesized or something. When I talk on the phone, people sound totally normal.
3. Do I even need to pay the $2.99 per month that I am paying Verizon for this service? Or is there a free app available that does the same thing?
I flashed my Verizon Note 2 (SCH-I605) to the SOKP Rom from a Jedi X Rom (v13 I believe). After the flash, I noticed my network was not working. Eventually I found out that the device was registering as a GT-7105. Not sure what went wrong, as the rom was flashed with no errors. I also ensured that my recovery was on the appropriate version (TWRP 2.6.3.3 in this case) and I also did a factory reset. To try and rectify the issue I wiped the phone and tried various other roms. In every one of those cases I found that the phone was constantly roaming. I had checked my network mode and tried switching between Global and LTE/CDMA which did nothing. Being completely out of options, I just installed to a stock rom through Odin (VRAMC3 4.1.2) and let it update via Wifi to 4.3 and still nothing. (I am well aware of the Knox security feature and will address this in a moment)
Here are the different ways I tried to diagnose the issue after this that led nowhere:
1. Made contact with a Tier-2 specialist from Verizon that tried various diagnostic methods and found that my phone was simply not registering on the Verizon network, or ANY other network for that matter.
2. I went to a Verizon store and got my SIM card replaced.
3. I even went to a repair shop to see if the phone possibly had a faulty connection.
I have already verified that the IMEI is correct based on the sticker behind the battery. The PRL is on 15310. The very last thing I tried was entering "getprop" inside a terminal. I'm taking a guess here, but I noticed my ril.serialnumber was all 0s. If I need to root my phone again to try something, I am more than willing to. My phone is out of warranty and not insured, I'm not really concerned about the Knox warranty trigger unless it will render my phone completely unusable.
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'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 .
