I am trying to get a phone object so that I can call and conference two numbers from within my application.
I have tried using the static PhoneFactory.makeDefaultPhones((Context)this) but have not had any luck.
CODE:.......
Error - Caused by java.lang.RuntimeException: PhoneFactory.getDefaultPhone must be called from Looper thread

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 RelatedAnybody know an easy way for an app to find all the instances of all the Activities currently alive in the current process?
Yes, I could register each one into a static List<> someplace from the constructor of each Activity, but that requires developers to remember to put that code into every Activity constructor, which is going to eventually miss one or two (not to mention keep the Activity alive longer than it should be, though that could be fixed by holding WeakReferences instead of strong ones, but that still misses the point), and that's going to mean one or two escape the list. I'd prefer to have a way to see all of them from Android's/Dalvik's point of view.
IIUC, there should only be one instance of a given service, it is a singleton. However, my (audio engine) service gets instantiated multiple times, although I do nothing for it. When the service crashes (for example when I uninstall the app through adb), it gets scheduled for restart ("Scheduling restart of crashed service.. "). I understand this is an effect of the service being sticky. After that, when my app starts, it calls startService() and bindService(), and the service gets appropriately started and bound. But the service is then reinstantiated and onCreate() is called repeatedly, as many times it was scheduled for restart.
Each instance then wait for clients to bind and register, but onBind() is only called in the "main" service instance. The additional instances wait a bit for client to bind, and since that doesn't happen, they call stopSelf(). But stopSelf() has absolutely no effect in these "dead" instances, onDestroy() is never called.
The "main" service instance does work as expected, and when it decides to call stopSelf(), onDestroy() is indeed called. Worse, all these dead instances accumulate, they never gets destroyed. Therefore, their only possible end is a crash (which happen every time I launch/install through adb), and thus scheduled restart.
So that in the end I get many of these dead instances, which are restarted progressively once by minute approximately.
I got a null pointer exception in an Activity onCreate() while trying to access my Application object (extended from android.app.Application).This exception occurred very rarely and i have no way to reproduce this again.My App starts a service on BOOT_COMPLETED intent and the null pointer exception seems to have occurred during boot up. Can somebody please throw some light on this issue? Application should have been created before creating any activities.
View 2 Replies View RelatedI've thought of some less than elegant ways to solve this, but I know I must be missing something.
My onItemSelected fires off immediately without any interaction with the user, and this is undesired behavior. I wish for the UI to wait until the user selects something before it does anything.
I even tried setting up the listener in the onResume, hoping that would help, but it doesn't. How can I stop this from firing off before the user can touch the control?

I want to do some automated testcase with Instrumentation . Suggest that my AUT has 2 Activity. After clicking the button in ther first Activity, the second one will be shown with new content base on what we enter in the first Activity.) Instrumentation provides us the function called startActivitySync() and return the Activity object for processing. My question is how we can get the pointer of the second Activity after the it is shown by clicking the button on the first activity.?

I am using the Telephony class to get messages ( Telephony.Sms.Intents.getMessageFromIntent(Intent intent)). But I can't find the class Telephony from its package(android.provider), there is an error named "The import android.provider.Telephony cannot be resolved" when import android.provider.Telephony.Sms.Intents, the sdk version I'm using is android-sdk-windows-1.0_r2, how can I use this with the new implementation of Telephony?
View 2 Replies View RelatedI have low expectations that this message will get any response as it seems that Google developers do not like to address issues too close to the Android core and to strategic mobility applications. However, as they say, hope is the last to die.
I am really puzzled by the lack of response to queries about issues with some TelephonyManager functions.
Specifically, there have been a number of requests in the past, including mine, about
getNeighboringCellInfo()
As per the link below, getNeighboringCellInfo() is a documented TelephonyManager function available to application developers.
http://developer.android.com/reference/android/telephony/TelephonyMan...()
Yet, getNeighboringCellInfo() does not work. Any attempt to call it in an application results in application failure.
What is the problem here? If Google does not want application developers to use this function (I cannot fathom why that would be the case), then please remove it from TelephonyManager, and save all of us time and frustration.
It's really puzzling that for such an open platform Android has so many secrets and rules.
There are a number of network types defined in TelephonyManager:
NETWORK_TYPE_GPRS
NETWORK_TYPE_EDGE
NETWORK_TYPE_UMTS
NETWORK_TYPE_CDMA
NETWORK_TYPE_EVDO_0
NETWORK_TYPE_EVDO_A
NETWORK_TYPE_1xRTT
NETWORK_TYPE_HSDPA
NETWORK_TYPE_HSUPA
NETWORK_TYPE_HSPA
Is there any info out there that describes what range of speeds you can expect on each of these? If that isn't available, it would be nice to be able to order them based on speed.
I was wondering if there is a way to manipulate the emulator to simulate telephony signal strength changes.
I would like to test code that uses TelephonyManager.listen() with LISTEN_SIGNAL_STRENGTHS.
I am currently working on porting a application written in C in android platform. I need to know that can i invoke/call the getSystemService from the C application using invocation interface by JNI.

I'm confused about the concept of the Context class. I see that it's a base class of Activity, but the Android docs also mentions the Context storing global information about the app environment. So in my app which has 3 activities, does that mean I have 3 distinct Context objects, or do they actually refer to 1 entity? Also, what is the lifetime of a Context object- does it live until the last component of this activity's process is garbage collected?

View 3 Replies View RelatedAs part of my widget, I use an instance of the Camera object.
This is what I want to do. The user will click on my widget, I get an instance of the Camera(if it's not already stored), use it, then store it. If they click the widget again, I want to use that same instance that I used previously.
I can't release the Camera(android.hardware.Camera) until the user clicks on the widget the second time. So the user clicks on the widget the first time, I get the camera and hold on to it until they click the widget again.
The problem I am running into is on the second click, I am trying to get the Camera again, which I can't because I currently have it in use.
