Android :: What Is Best Way To Stop Activity And Alert User?
Sep 2, 2010
I have an application that must create a database and if that fails, then no sense moving forward. I've built an AlertDialog and show() it but it never displays. The logic falls through and then barfs because of the missing database.What is the right/best way to throw up a message and halt the activity? The code below executes fine (meaning the show() occurs while debugging and it falls to the next line) but the UI never displays this alert.BTW I realize the throw might not be the most graceful but I'm not even getting that far so.

My Captivate has been nothing but a pain. The GPS comes and goes and the response time is horrible with the touch screen (give me old-fashioned BUTTONS any day!) Now the 'message' alert continues to go off and I can't stop it; I finally had to mute it. I have rebooted and even removed the battery and it won't stop.

Since upgrading to 2.1, I've been receiving a text alert for every voicemail I get. I've black listed these messages in the past. Since the update, the text alert comes from the individual. If I black list it, I don't get any text from that person.

This is really annoying and concerning. Anyone having this problem and not using a task killer? Obviously phone on / off fixes, but worried about missing call.

How can I disable the keyguard when a broadcast receiver is activated by screen_on, so that when it occurs the user sees an activity that I have started behind it?(The activity is running already)I have been trying the following code from a broadcast receiver triggered by screen off.It doesn't seem to be working though as it is. When I turn the screen on, I still have to manually unlock the keyguard on the phone to reveal the activity behind it.

Is there a way to reprompt the user to choose a default activity for an intent? For example, user selects his default home apk and I want him to reconsider his choice once again. I know how to do that on 2.1 and before, but is there a way to do that now on 2.2? Famous Home Switcher, which did similar thing, does not work on 2.2 anymore thanks to google team.

I would like to launch an intent when any of my activity is visible, otherwise I will put it up as a notification, and will be fired by the user. To decide this, I need to know if any of my activity is front-most, how do I that?

I'm trying to implement similar behavior as the native phone app. When a User is in the applications menu/drawer (place that lists all applications) and receives and incoming call, after the call has ended the User is returned to the Android Homescreen. How do I redirect activity to the android homescreen like the phone app for that specific case.

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.

I am creating an alternative keyboard. In order to help users understand how to set up the IME after it is installed I have added a simple Main Activity that appears in the Application Launcher with set up and usage instructions. I also have a preferences Activity and I want the user to have an option to hide or show the setup instructions Activity if they don't want to see it any more. My question is how best I can do this? I am assuming if it is possible it would require overriding the IntentFilter for the setup instruction Activity. I have experimented with this and read through the Intents and IntentFilter documentation but I can't see how to do this.

I understand that trying to capture home button clicks is a hack, but I need to atleast close my current activity when the user clicks on home button. Is there anyway I can tell the system to close this activity is the user clicks on home button? If so how can I do that? I need to do it as I am listening for location updates and I want to stop the updates and also need to trash any location that was available to me previously. I need to do this just in case any user while in that activity clicks on home button and changes the location settings.

My MAIN activity is spawning a child activity that contains a ListView. While this ListView is being populated (through an AsyncTask), an indeterminate progress bar is shown.However, assuming that I am an impatient user and I press the BACK button, the progress bar is cancelled but I am left with a blank screen. I have to press BACK one more time to go back to the MAIN activity.I would like the app to go back directly to the MAIN activity by pressing BACK only once. Can somebody point me in the right direction? I am thinking I should call finish() somewhere but I don't know where to put it.

Is there a way to retrieve Browser's user-agent without having a WebView in activity?
I know it is possible to get it via WebView:
WebView view = (WebView) findViewById(R.id.someview);
String ua = view.getSettings().getUserAgentString() ;
But in my case I don't have/need a webview object and I don't want to create it just for retrieving user-agent string.

I want dont want the activity animation that comes by default when we start a new activity (i.e. the right to left scrolling effect to new activity view) so i googled a bit and found a flag FLAG_ACTIVITY_NO_ANIMATION in the Intent class also i applied that flag to my intent via the setflags() method but somehow i still see the activity animation when a new actvity is launced ( i am developing in android 2.1 update).

My problem is: Activity A called Activity B, and in Activity B, it start a background thread to do some client-server work. But it maybe takes too much time. So i add a cancel button to call the stop() method to stop the thread, and call finish() to finish the Activity B and go back to Activity A. Although it is back to Activity A, the thread isn't stop immediately. Can i just call the finish() to go back to Activity A, and leave the thread to exit by itself? If it is not the right way, which is?

I have a START and STOP button in the main screen of an App. there are some GUI and threads that are instantiated when I click on START. When I click on stop, I want everything to be stopped and the activity should come back to its origin state. To the state that is exactly same like when launched (when we tapped on App icon in mobile).Is it possible to do this? I tried with finish() , this killed the app and exited . I don't want to exit from main screen. rather, on clicking STOP I want app to come back to origin or born state.
