Android :: Resuming An Activity From Notification
Mar 5, 2010
I have a notification in the status bar for my app.The problem with this is that when you press the home button from the app (pushing it to the background) then press on the notification in the list accessed from the status bar, it starts a fresh copy of the activity. All I want to do is resume the app (like when you longpress the home button and press on the app's icon). Is there a way of creating an Intent to do this?

I am trying to solve an issue sort of similar to what was done here (link text)Except in my case where Activity A, started Activity B, started Activity C, when the user resumes the app after pressing the home button - I want C, the last Activity, to be displayed. Instead what is happening is I am back to A.Also on a side note I have discovered that even when I exit the application, if I hold down the Home button, my app is still listed as an active app even though in the LogCat I can see that it exited OK.Also, in case it matters, I did recently add android:launchMode ="singleTask" in order to make some notification logic work correctly. I was seeing the Home button behavior before that though.
Activity B actually has several Activities that it chooses from (it has a list of Intents) to display based on input it receives but launches them all the same way as Activty A launched B. Once the first Activity is displayed the user swipe the screen to navigate to the left or right screen. When the user swipes left or right, the current activity puts info in its return Intent that Activity B uses to display the next Activity. Also since logic outside of the user's control could prompt a change in the screen displayed, each Activty calls finish on itself in onStop to avoid back-button issues.

I have two activities running: MainActivity and ChildActivity. Whenever the user clicks in the button in MainActivity, the ChildActivity is launched. What I want to do is this:When the active activity is the ChildActivity and the user clicks the home button then relaunch the application (like opening from the beginning), I want to see the ChildActivity instead of MainActivity that is launched. However; This is happening only when the user clicks from recent activities window. (the window opened when you long press the home button).I had some suggestions actually work arounds and I tried to manipulate onStart, onRestart, onResume, onStop, onDestroy events. But, they didn't fully solve the problem. There should be a smart way out there.

I have an application that I have running a media player and I want to resume the activity from my applications home activity. I can successfully do this by adding the following flags to the startActivity Call:
myIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);
I am worried that this is not an ideal way to do things since it took me a long time to find it. It made me think that no one uses it very much. Are there any pitfalls to using this method?

My application uses a single activity to switch between different views. I premise I'm loading a good amount of bitmaps in one of this view (say the gamescreen view) constructor but I recycle everything on the onDetachedFromWindow method.All the Bitmaps are static and most of them loaded with BitmapFactory. decodeResource method.Furthermore I'm using a gallery wich content is a simple layout with eight imagebuttons.I know all the complications using this widget and all the risks of using static bitmaps, but, I guess my problem does not entail them because my application is running well if I try to switch between these two view (and I've tried to do it about 30 times without crashes!!!) but when I pause and resume the application two times (pause->resume->pause->resume) I run out of memory, and often without the crash message (it just stays on the actual view).

I am stuck.My main activity creates and starts a SurfaceView.My app needs to access a listview via the options menu to change properties of the items shown in the view.Two strange things occur:
1.) When I scroll the listview quickly, the list sometimes gets farklempt.Words overlap each other.
2.) When I select the item and the app returns to the main activity, the thread is no longer alive.
If someone out there can offer help I will post the code.This will take a little effort.My code is loosely based upon LunarLander and the GLSurfaceView examples.If there is a good example (more recent example) someone can point me to, that would be boss.

We are developing an application that needs to suspend and resume threads like a debugger (meaning in a non-safe way like Object.wait() and Object.notify()).In the Java SDK the methods Thread.suspend() and Thread.resume() are deprecated but we can still use them. Also there is the Java debugger API which allows one to do that if you connect to the VM as a debugger. Is there some API for android we can use? Is there a published Java Debugger API we can apply for Android?

I'm having some difficulty figuring out the best ways to pause and resume my application. Is there any comprehensive tutorial or something similar that would help me make sure that I'm not missing any important steps?Mostly I'm just worried about not dealing with the memory being used by my application. There's a few apps I own that when you minimize them slow down the rest of the phone to a stand still and I want to make sure to avoid that.

I am trying to implement the functionality to resume a large file download, but have not found how to start downloading from a position that is not at the beginning of an InputStream.I am currently using the InputStream.skip() method to go to the position where I want to resume the download, but have found that this method actually reads all the data over the network and then throws it away.I would appreciate some help in learning the correct way to start reading from the resume offset of the internet file being downloaded, so that I can avoid wasting the phone network bandwidth, and also avoid the extra time delay caused by re-downloading all the data that was already previously downloaded.

I've run into a very strange problem regarding OpenGL texture outputs, which only occurs when the app is resumed (particularly when leaving after pressing Home, and going back into the app).I'm not sure how or why, but it appears to be that it's reading bitrate of the pixels incorrect, or something else entirely. Furthermore, this issue only occurs on the device itself (testing on my G1/Dream), not on the emulator.Code as well as example screenshots in the zip file show exactly what I'm talking about. And to completely replicate the issue I've included the 2D sprite object framework I've developed for OpenGL so the situation is exactly the same as what I've run across when developing my game, so if it's somehow an issue in my framework you may be able to spot it.

I have one simple question regarding Java TimerTask. How do I pause/resume two TimerTask tasks based on a certain condition? For example I have two timers that run between each other. When a certain condition has been met inside the task of first timer, the first timer stops and starts the second timer, and the same thing happens when a certain condition has been met inside the task of second timer.how do I pause timer1 while running timer2 and vice versa while timer2 is running? Performance and timing is my main concern as this needs to be implemented inside another running thread. By the way I am trying to implement these concurrent timers on Android.

When MountService received event from HAL and start a notification, it would display an AlertActivity after user's click. However, I found the AlertActivity is created and can't be displayed.
I got some log as below:
CODE:........
Is it related to "FLAG_ACTIVITY_NEW_TASK"? however, how to solve it?
I've tried to use "launchmode as singleTask", but is doesn't work.
Is there anyone give me a hand? Why my activity can be created but can't be displayed?

Is there a way of recieving a notification of some sort when a activity is launched. I'd like to monitor which applications are used and how often. Is is possible to register for some broadcast telling me when an application is launched, installed, unistalled etc? I believe I found a discussion or solution to this yesterday when I was looking for something else, but I'm not able to find it today.

I am launching a mail activity by
//Sending mail final int SENT_MAIL = 1;
startActivityForResult(Intent.createChooser(i, "Send mail"),SENT_MAIL);
and in
onActivityResult(int req, int res,Intent data)
I am trying to find the result of email sending, so as to confirm if my mail was sent or was discarded by the user. I am receiving null for Intent data.
i.e. data =null
parameter in onActivityResult(int req, int res, Intent data), res is always 0.
ie. res = 0;

I have a server socket bound to a port and I want to send notifications using NotificationManager when a client connects. This all works well.
What I want to avoid is sending notifications if a specific activity is currently being used by the user. E.g., I'm trying to avoid something like GMail notification if I'm already reading email.

Application (non-wanted) behavior - application is started, some text is put into text-box and notification is created through button action. user "clicks" the home button, application is "minimized", notification is available in bar user selects the notification and the application is "maximized"
BUT - instead of the original instance, new instance is started (e.g. in the newest instance is missing the original text; when the latest instance is closed there is still the original instance with original text ) .
The code of the notification method
CODE:.....
I have also in the manifest xml file following tag android:launchMode="singleTask"
But it is still the same...The main problem is double/triple initialization of the application, i know that there are other means to preserve the values in resumed applications. Also it is needed that the applications stays running in background as the main functionality is the streaming of internet radio.
What is missing in the code ? What kind of information from my side is missing for to troubleshoot the issue ?

I create an application which displays the notification when the service starts. If an user navigates to HOME screen (without exiting the application), the user could still go back to the previous application by pressing on the notification icon. This is very similar case as the track recording service in Google application "My Track".
I want the existing activity as Single Top activity since it has associated service running. However when my application tries to bring the existing activity to front via notification, the existing activity's onDestroy has been called which causes problem. How can I skip this onDestroy method? Here is my current codes:

I have one Android application, when it runs a service, I want to show the notification on the status bar. Then the user could navigate to other application by pressing HOME key. However when I try to bring the previous running application back to Front via notification icon, there is some problem with the existing activity. Even I declare it as "Single Top" mode (I want to run the existing activity since there is an associated service running) , somehow that activity's OnDestroy has been called before OnResume. Here is my code of creating the notification object.

I like to download podcasts to my hero which can take a while because they're pretty big files. If I get an email or text while downloading it pauses my download and says waiting for data connection. The same thing happens sometimes when it bounces from WiFi to Ev. The only way I can get it to start downloading again is to start another download. This is annoying so does anyone know a better way to resume a download or is there some setting I can change?

Is there any way for an activity to register for being notified if a wait/force close dialog is shown or alternatively if the user selects force close, a way to detect that in ondestroy()?
