Dec 1, 2009

Hello all, I am new in android developer and I would like to make a sip based application for this platform. In the signaling part I have found about jain-sip (used it) and sipdroid( any good tutorial? ) the problem starts when I want to stream data from a phone to a server. So the question is: Is there any stack for RTP? does the new SDK support this?

Android :: Bluetooth Stack Becomes Unresponsive

Apr 13, 2010

After Bluetooth connection is lost. Bluetooth stack on HTC Legend is messed up. Nothing works till Bluetooth is turned off and on. Here is the sample, the problem is blocking read on the thread but InputStream.available call always returns 0 and cannot be used to implement some ugly, busy-waiting workaround. package com.example.android.disconnectproblem; import java.io.IOException; import java.io.InputStream; import java.io.InvalidObjectException; import java.io.OutputStream; import java.util.UUID; import android.app.Activity; import android.bluetooth.BluetoothAdapter; import android.bluetooth.BluetoothDevice; import android.bluetooth.BluetoothSocket; import android.os.Bundle; import android.os.Handler; import android.os.Message; import android.util.Log; import android.view.View; import android.view.View.OnClickListener; import android.widget.ArrayAdapter; import android.widget.Button; import android.widget.ListView;

Android :: Clear Activity Stack?

Nov 3, 2009

Is there a way to clear our Activity stack? For example, a user in my app progresses through these activities, one is launched from the previous activity: ActivityA -> ActivityB -> ActivityC if the user is now looking at ActivityC, and they hit the back button, they will go back to ActivityB. Is it possible to add a menu to ActivityC where the user can clear their activity stack, and then launch a new instance of ActivityA? This would be so the user can jump to a particular activity in my application without getting confused with the back button + history,

Android :: How Do I Clear All Activities From Stack?

Jul 8, 2010

I am having trouble popping all activities off the stack using ntent.FLAG_ACTIVITY_CLEAR_TOP and android:launchMode="singleInstance". In my application activity A, launches activity B (via startActivity) which in turn launches activity C (via startActivity). On activity C the user presses a menu item to return to activity A. When they arrive at activity A, I want only A on the stack such that if they click the back button they return to the home screen (desktop). This is the code that I am currently using when the user presses a button to return to A: Intent i = new Intent(this, A.class); i.addFlags(Intent.FLAG_ ACTIVITY_ CLEAR_TOP); startActivity(i); All activities are defined as android:launchMode ="single Instance" in the project manifest. My code doesn't seem to work though. Once I'm back on activity A if I click the back button I return to activity C. Am I misunderstanding how to use Intent.FLAG_ACTIVITY_CLEAR_TOP?

Android :: Way To Tell When Task Goes To Back Of Stack?

Mar 23, 2009

Is there a way to tell when my task gets put on the back of the UI stack (user pressed "home" say?) I have some resources I'd like to free when not foregrounded. The lifecycle routines seem dicey to use to try and infer this. The "home" key does not seem to be passed to onKeyDown(), and moveTaskToBack() is never called by the system so I can hook it. I can poll the ActivityManager for running activities with my task id, but hard to find a good time to call this.

Android :: Activity Stack Not Preserved

Mar 10, 2010

My main activity A has as set android:launchMode="singleTask" in the manifest. Now, whenever I start another activity from there, e.g. B and press the HOME BUTTON on the phone to return to the home screen and then again go back to my app, either via pressing the app's button or pressing the HOME BUTTONlong to show my most recent apps it doesn't preserve my activity stack and returns straight to A instead of the expected activity B.Is there a setting I'm missing or is this a bug? If the latter, is there a workaround for this until the bug is fixed?

Android :: Traversing Activity Stack

Sep 1, 2010

how can I assure I always go back clicking on custom menu option to previous activity. I think it is a good idea to start new activities by startActivity(context, XActivity.class) but then when option is selected I should call finish on that activity or again call startActivity(this, previousActivityName)?on the other hand android has all activities on a stack so clicking goback button on a phone I will always go back to previous view, so how can I get this stack.

Android :: Resetting Activity Stack

Sep 22, 2009

Activities: A & B are activities that once you have navigated away from them it's not logical that you can get back to them using the back button. C X are activities that follow the usual "can go back to where you came from" flow.App flow: * Launch app from Home -> starts A * From A start B * Finish A (removes it from stack) * From B start C * Finish B (removes it from stack) * From C start D * From D start E.Once the user has reached E, the activity stack looks like this: C -> D -> E. Can I somehow reset the whole stack so it starts again at A so it's as the user just launched it from Home (so that C... E are removed from the history stack)?

Android :: Not Understanding Activity Stack?

Dec 3, 2009

I'm having trouble with my activities when they go in the background. I have two activities, A and B. Only A can launch B (manifest copied below).This is very confusing. It's like Android knows my app is running, and puts a new instance of A on top of the old B instance running. I'd just expect that the application gets paused in-place, and whenever the user hits the app icon again, it just picks up where it left off (in this case, just show B again!) Below is the manifest, and the activity classes for this test are completely empty (except A which has a button to launch B).

Android :: How To Reuse Activity On Top Of Stack

Jun 16, 2010

My app has a single entry activity called "Main". In "Main" I call one of three other activities A, B, or C (based on a preference) and then immediately exit/finish"Main" so that only A, B, or C are active.I also have a permanent notification in the notification bar that users can pull down (at any time) to conveniently restart my App (calls intent with "Main" component).The problem is that if my app is already running and users pull down the notification and restart, I get A or B or C running on top of the previous activity (also A, or B, or C). How can I avoid this (i.e. reuse the activity on top of the stack)?I've tried Intent.FLAG_ACTIVITY_* and nothing seems to work. I've tried launchModel in the Manifest and it also didn't seem to work.

Android :: How To Clear Current Activities In Stack?

Jul 26, 2010

Support App starts activity A, then A starts activity B and finishes itself. After that activity B starts activity C. Now the stack contains B and C, with C at the top. Then I click a button in activity C, and want it to clear B and C and start activity A, i.e. I want activity A to be the only activity in the stack. How can I make it?Edit: I made a test to use FLAG_ACTIVITY_CLEAR_TOP. But it didn't work in my case, because activity A is not running when button in activity C is clicked.

Android :: SingleTask Really Always At Root Of Activity Stack?

Sep 16, 2009

In the documentation it is stated that an activity with launchMode="singleTask" is always at the root of the sctivity stack. However, when I run my "singleTask" activity for a few scenarios and monitors behaviour with "adb shell dumpsys activity" I can see it placed both at the top of the stack (with numActivities=2) and in the middle of the stack (with numActivities=3). The activity at the root (frontOfTask=True) has a "normal" launchMode.Is the documentation incorrect or am I missing something?

Android :: SingleTask / Activity Stack Not Preserved?

Feb 18, 2010

I have an activity, ActivityA, and its launchMode is set to "singleTask".I start the application from the app tray. ActivityA launches ActivityB from a button click. ActivityB is a normal activity with no launchMode set ("standard").With ActivityB on top of the activity stack, I hit the home button, then resume the app, I see ActivityA instead of ActivityB when resumed.Shouldn't the history stack be preserved in this case, and B be showing? When I resume, I see A get onNewIntent() called, and I'm not sure why this is happening. I thought the stack would be preserved.

Android :: Enumerate Activity History Stack

Dec 17, 2009

When debugging I've sometimes wanted a tool that would list running tasks and show which activities are on the history stack for each task. I can get a list of tasks by calling ActivityManager.getRunningTasks(). Each ActivityManager.RunningTaskInfo object in the list gives me interesting information such as the base activity, top activity, and number of activities in the task. I haven't found a way to actually enumerate all the activities in the task's history stack. Is there a way to get at such information?

Android :: Passing Keyevents To The Next Activity In The Stack

Apr 4, 2009

I'm trying to create an activity which would be on top of other activities (a small dialog themed activity) and I want to get ALL key events to be ignored by my activity and handled normally by the activity beneath it. When I say all I mean the send, end and back keys too. Is this possible?I've tried setFocusable(false), setting the flag FLAG_NOT_FOCUSABLE, and adding a dummy onKeyListener but nothing doesn't seem to do the trick.
