I have an application where I navigate from Activity A to Activity B and back to A and then B. I want to resume the activity B (which has a Bundle passed to it ) from Activity A. The documentation says that OnSaveInstance() is called only when the activity is killed, so how do i use OnPause which does not have the Bundle to resume the activity B.

View 1 Replies View RelatedI tried the following from an activity:
@Override public void onPause() { super.onPause();
postDelayed(new Runnable() { public void run() { mTextView.setText("I am paused!"); }, 10000); }
The activity, while in the background, still executes the runnable. Is this incorrect? Should we absolutely call removeCallback() from our onPause() handler to ensure that no postDelayed() runnables execute if we get paused? Or is it necessary to do this only in onDestroy()?
I have a webview and when I do some java-script processing on it. I click on a link to play a video, after the video finishes in full screen. I want to return to my webpage in the same state I left it before clicking to play the video. How can I do it? Any snippets?
View 1 Replies View RelatedI have a small test application I am working on which has a timer that updates a textview to countdown from 100 to 0. That works fine, but now I am trying to pause the application if the user presses the back button on the phone and then restart the timer from where they left off when they reopen the app.
From the Log.v() prints I see that the _timer_time_remaining variable has the correct number of seconds stored when onPause is called, but it is set back to 0 when onResume starts. Why does the variable get reset? I thought that the application would continue to run in the background with the same values. Am I missing something? This is all declared in a class that extends Activity.
I'm not sure why onPause() is not called in the following scenario.

View 1 Replies View RelatedI'm currently working with a two-activity application. The first activity allows the user to choose options for their upload, and the second activity displays a ListView of their results once processed.I have code in place that performs the uploads/downloads in the background, regardless of whether the application is currently in focus or not (thanks to Matthias Kaeppler's Droid-Fu).I would like to have my application Resume into my second (results) activity when a user clicks on the icon from the top-level launcher, regardless of how long they have been away from the app. I thought that the 'alwaysRetainTaskState' flag in the Manifest would do it, but I've not had success with that. Can anyone tell me how I need to set up my Manifest to get this functionality?

View 2 Replies View RelatedSo I have a MapActivity that runs an asynchtask that occasionally updates what exactly it's displaying on the map (via a string). I originally pass this string in from the intent when the activity is first created. And then if you click on one of the drawables on the map, it opens a new activity, which can then create a new mapview (same class) with a different string setting. The problem I have is that I only want one instance of the mapview to be running at once. Thus I set android:launchmode="singletask" in the manifest. This works in that it brings the mapactivity to the front, but is there any way to send it a new intent bundle to get a new setting for the string it needs? I tried regetting the extras from the bundle, but it seems to retain the old bundle, not the new intent that was passed to it. I'm not sure I want to do startActivityForResult because the 2nd activity may or may not want to update the original activity. I hope that made sense. I can post code if necessary, but I think that should explain my situation.
View 2 Replies View RelatedI have an activity that is showing a video and when the user clicks a button, a new activity is launched. When the video activity stops, I pause the video view. When the video activity starts up again, I try to resume the video view videoView.start(), however, the video starts over from the beginning. I'm thinking that the buffer must be lost somewhere, so I now try to capture the current position via videoView.getCurrentPosition(), however, this is always returning 0.
Anybody know how to resume video playback when an activity starts up again?
Can someone tell if why when starting an activity with startActivity(intent) , calling getParent() in onCreate() of the new created activity returns a nul ?
Also how could I obtain the parent of an activity created in such a way ? Can a reference of the activity below the current activity in the activity stack be obtained ?

I've got an activity that calls a helper class called DownloadManager. DownloadManager spawns a thread that downloads a mp3 to the sdcard. I'm having some trouble finding the best design for resuming the initial activity and starting the MediaPlayer. Does it make the most sense to use a BroadcastReceiver that receives a message that download is complete, then start a new Intent of my activity? Think I saw something that I can't use an Intent to start an Activity from BroadcastReceiver because it is a background process.

View 5 Replies View RelatedI have a notification that starts my activity and passes a messages using the intent's putExtra() function. The message is then displayed to the user in the activity's onCreate function. When the application is restarted due to a orientation change, the message is shown again as it is still in the intent's bundled data.
How can I remove the extra data?
I tried the following:
Bundle bundle = getIntent().getExtras();
if (bundle.getBoolean("showMessage")) {
// ... show message that is in bundle.getString("message")
// remove message
bundle.remove("showMessage");
}
But the message will still be shown after the orientation changed, seems like the intent used is not the one I changed, but the original one. The only workaround I found is to save the showMessage additionally in onSaveInstanceState(). Is there another way? Or is this the way to go?
I have tried to freeze orientation: setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
But thought screen stays in portrait orientation, the activity is still recreated.
I'm using an intent-filter on URLs for my activity:
CODE:...............
the launchMode attribute is set to "singleTop", but it looks like a new activity is created every time I click a matching url. I thought that if the activity is already alive somewhere, it would simply be brought to the front of my activity stack?
I tried this on the emulator/device, same behavior, a new activity instance is always created.
I am checking to see if my app has a network connection Whenever I rotate my screen between landscape and portrait this method returns false. It makes me wonder if Network connections are getting killed during the rotation?
View 1 Replies View RelatedI am trying to apply an animation to a view in my Android app after my activity is created. To do this, I need to determine the current size of the view, and then set up an animation to scale from the current size to the new size. This part must be done at runtime, since the view scales to different sizes depending on input from the user. My layout is defined in XML. This seems like an easy task, and there are lots of SO questions regarding this though none which solved my problem, obviously. So perhaps I am missing something obvious. I get a handle to my view by: ImageView myView = (ImageView)getWindow().findViewById(R.id.MyViewID);
This works fine, but when calling getWidth(), getHeight(), getMeasuredWidth(), getLayoutParams().width, etc., they all return 0. I have also tried manually calling measure() on the view followed by a call to getMeasuredWidth(), but that has no effect. I have tried calling these methods and inspecting the object in the debugger in my activity's onCreate() and in onPostCreate(). How can I figure out the exact dimensions of this view at runtime?
I am launching the VideoCamera activity from my main activity but not able to get a callback to read the file created.

View 1 Replies View RelatedI'm using an AsyncTask in my activity. Looks like:So if the user is rotating the device, onPause() will get called, but I don't want to cancel the task just because of that. I know there's a way to tell the system to not actually destroy my activity on rotation, but is that recommended for this problem? Should I instead put the AsyncTask in a static global class that won't be bound to the Activity?
View 3 Replies View RelatedI have created a simple game for Android; I want to prevent users from sending the game to the background by pressing the home or back buttons accidentally. I planned on using a dialog to confirm the user's action. What I want is similar to what Sirius does with their app, if you need an illustration.
I tried adding this action to an overridden onPause(), but the activity vanishes right after the dialog is displayed, so I don't think I'm going about this the right way. How can I fix this?

My main activity listens for GPS fixes, which I want to continue working when switching to another screen/activity. Therefor I cannot unregister my LocationListener in the activity's onPause().

Any ideas?
I'm having a hard time figuring out the best way to pass simple values from onPause and onResume in the Android activity lifecycle.
