Android :: Activity Can't Be Displayed From A Notification

Apr 9, 2009

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?

Android :: Make Sure An Activity Is Displayed Before Another?

Aug 19, 2010

I have some activities and I have to display a fullscreen ad image before displaying the activity... all my activities extends a custom activity and I thought it was a great idea to implement that advertisement there, so I did: code...

This works nice... the ad is displayed for 3 seconds and it closes automatically. The problem is that the activity that should be hide for the ad is being created faster, so the user can see it for a second before the ad is created. How can I avoid that behavior? How to make sure the ad activity starts before the another does?

Android :: Activity Is Displayed After User Unlocks The Screen

Mar 31, 2010

I was wondering if anyone understood how to make your application be displayed when you unlock the screen. I have an application where the user turns on a Bluetooth device, it connects to the phone, and the user should be presented with a UI. Having them hunt for the app or using the notification menu is not a workable option (too much work and not the obvious behavior).

The problem is that:
When the screen is unlocked:
- you can popup the activity from the background service when Bluetooth connects to a device
- User is happy because the UI is right there

When the screen is locked:
- The application gets started but is destroyed
- User unlocks the phone and nothing is there but the homescreen

One work around would be to disable the keyguard when the application gets woken up but the nuclear option is a pretty bad option. I know the standard Android assumption is that you shouldn't do this. In the normal case this behavior is fine, but in this case I explicitly did something I want the phone to respond without adding more work for the user to do. As per Google's guidelines if you don't like this behavior there can be an option for you to turn this off or you can not use the application.

A few more details, so after looking at this a bit more the problem isn't necessarily that you can't have an activity running when the screen is locked, unlock and expect it to be waiting. That does work if you do something like the following: lock your device run an app through Eclipse while the phone is locked/off unlock and it will be waiting for you.

But in the case the Activity is already running and I'm brining up a new window (which happens to be a transparent one, saying you're connected and asking what they want to do).

The problem is that it gets killed

CODE:..................

The setup here is as follows:

MyBackgroundService is a serivce that handles Bluetooth state (waits for connections, turns on Bluetooth if the user starts the app, etc.). It triggers a popup BackgroundPOPUP activity that runs a ViewFlipper.

MyBackgroundService starts BackgroundPOPUP through an intent.

BackgroundPOPUP is an activity with a Translucent theme (Theme.Translucent to be precise), it shows a ViewFlipper with some instructions and presents some options.

Android :: Create SPP Connection For Bluetooth - Pairing Notification Is Displayed

Mar 30, 2010

When my Bluetooth application is about to create SPP connection to the unpaired remote device, pairing notification is displayed. From the documentation I can see that pairing request can display a dialog or sent notification. I'd like to know what logic causes my app to sent notification than display a regular pairing dialog. Maybe I'm blind but the problem is I were not aware of that notification and was fighting with pairing problem for few hours :) And I'd really would prefer my app to trigger dialog display.

Android : WebView - Not Able To Go Back To My Activity Screen Once The Content Is Displayed

Apr 9, 2009

Step 1: I am subclassing WebView and rendering html content properly. The intial content is very small with a div and image /link This is displayed in a LInear Layout along with a TextView and ListView. That is my first screen/activity of the application.

Step 2: When I click on a link on this webview, it goes through the webViewclient and expands to full screen to fit the content of the requested page.

After Step 2, I am not able to go back to my activity screen once the content is displayed. When I click on the back button to getback to my activity screen close my activity and goes to the phone's applications desktop. (i.e goes out of my application).

Step 3: In order to fix this issue, I stopped setting my own subclasssed WebViewClient. After doing this, the it seems to render the clicked page in a webView as subactivity. Now When I click on backbutton, it goes back to the activity screen. But, the issue now is, I am not catch event when a link is clicked. How can I catch click events in this case.

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?

Android :: Can I Avoid Sending Notification When Activity Is Currently On Top

Sep 13, 2010

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.

Android :: Prevent New Activity Instance After Clicking On Notification

Jun 24, 2010

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 ?

Android :: Bring Activity In Background To Front Via Notification

Aug 5, 2010

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:

Android :: How To Bring Existing Activity To Front Via Notification

Jul 28, 2010

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.

Android :: Status Bar - Opening Correct Activity When Selecting Notification

May 26, 2010

I have been having a problem with a notification not opening/going to the correct activity when it has been clicked. My notification code (located in a class which extends Service):

Context context = getApplicationContext();
CharSequence contentTitle = "Notification";
CharSequence contentText = "New Notification";
final Notification notifyDetails = new Notification(R.drawable.icon, "Consider yourself notified", System.currentTimeMillis());
Intent notifyIntent = new Intent(context, MainActivity.class);
PendingIntent intent = PendingIntent.getActivity(context, 0,notifyIntent, PendingIntent.FLAG_UPDATE_CURRENT | Notification.FLAG_AUTO_CANCEL);
notifyDetails.setLatestEventInfo(context, contentTitle, contentText, intent);
((NotificationManager)getSystemService(NOTIFICATION_SERVICE)).notify(NOTIFICATION_ID, notifyDetails);

If I click the notification while the application which created the service is open, the notification disappears (due to the FLAG_AUTO_CANCEL) but the activity does not switch. If I click the notification from the home screen, the notification disappears and my app is brought to the front, however it remains on the activity which was open before going to the home screen, instead of going to the main screen. How do I specify the activity that will be pulled up?

Android :: Starting Activity Through Notification - Avoiding Duplicate Activities

Feb 24, 2010

I am currently showing a notification. When the user clicks this noticiation, the application is started. The notification persists, to indicate that the service is running in the background.

CODE:..............

However, I have detected a case where a bug appears. If the user starts the application through clicking the normal icon, and while the activity is running clicks the notification, then a new activity is started without the earlier one exiting, the later being on top of the earlier. And that is not all: Further clicks on the notification will create additional activities and place them on top of those already running. How can I prevent this? Is there a nice check to do to see if a certain activity is currently being shown or is loaded?

Android :: Droid Notification Activity Doesn't Display Occasionally / Can I Fix It

Oct 6, 2010

I have an android background Service that will occasionally post a notification to the Status Bar using the Notification class. Occasionally, when I receive a notification, pull-down the notification window, and select the notification from the list, the specified Activity doesn't start. When this happens, the screen dims (as if it were about to display the Activity), but the Activity is never shown. I included my code below...

NOTE: The UserNotification class extends Activity, and is set to a dialog theme in the manifest. This class also has its taskAffinity property set to "" in the manifest.
