In an Activity, I have some snippet of code that fires off a Message...
Why is the Bundle not preserved in the Message ? Who is resetting the values of the Bundle ?

Can someone do a favor for me: open the stock Messages app, open up one of your ALREADY EXISTING threads (dont click "new message"), and try to type really fast. Is there keyboard lag? For me, there is a lot of keyboard lag. It's so slow that, sometimes the autocorrect box does not pop up in time, and I'm just typing freely without corrections.

I've been a couple of days trying to solve this thing but I can'f figure it out.The problem is, simple activity, with simple layout, ScrollView -> LinearLayout -> and a lot of buttons inside the layout (within the scroll content). Everything works just fine but one tricky thing. When I click a button let's say at the top of the scroll content and inmediatelly I scroll down to the bottom of the content and I click other button there, nothing happens until I click a second time and all come to normal again.This can be reproduced anytime and it's code independent (i've tried more than 20 scenarios). I've not much experience in android yet but looks like the scroll listener stops the onclick listener or something like that.
View 1 Replies View RelatedSo I've been extremely frustrated by this for a long time now.I've posted before, but can't seem to find a good solution. My goal is to have something pretty much exactly like the installed application details page in the Android Market.I need a list of items displayed along with other content above the list, and would like the content above to scroll up along with the list (exactly like the application details does for the "My Review" and other descriptive info).Due to responses to my previous posts, I came to believe that it really wasn't possible to do this with a ListView.So rather than using a ListView, I refactored my code to use a simple LinearLayout and add individual View items to the list, thinking I could just set each View as clickable and add an OnClickListener to each View in the LinearLayout.That's not working at all though, and now I'm getting even more frustrated.If someone can help me get the OnClickListener working, then I think it'll work, but I do need a separator for the LinearLayout.How do I add a separator like the one used for ListView to my LinearLayout?

Is it possible to use bundle and save the data in OnPause() lifecycle method? The scenario is i have 2 edit text and have entered some data i want to retain the data when the activity is killed and started again. his can be achieved using onSaveInstanceState() but as documentation says, this method is not a lifecycle method and hence the callback is not guaranteed. So i wanted to know if there is a way to save it using Bundle in onPause().
View 5 Replies View RelatedI'm well aware of onSaveInstanceState(Bundle b) and the corresponding onCreate and onRestore. What I want to do is persist the bundle somewhere simple where I'll only ever have one at a time. The functionality is to be able to resume a game from its previously stored state - not to be confused with restoring the activity during its lifecycle. I want to restore it AFTER it's been destroyed (think of turning the phone on and having a button on the game that says, "resume last game". My thoughts are that if I can just persist the bundle that I normally use for the instance state, then I should be able to reload it later upon user request. I don't want to use a provider because they seem way too over the top for what I'm doing.
View 4 Replies View RelatedI'd like to serialize a Bundle object, but can't seem to find a simple way of doing it. Using Parcel doesn't seem like an option, since I want to store the serialized data to file. Any ideas on ways to do this? The reason I want this is to save and restore the state of my activity, also when it's killed by the user. I already create a Bundle with the state I want to save in onSaveInstanceState. But android only keeps this Bundle when the activity is killed by the SYSTEM. When the user kills the activity, I need to store it myself. Hence I'd like to serialize and store it to file. Of course, if you have any other way of accomplishing the same thing, I'd be thankful for that too.

View 4 Replies View RelatedI've gone through the Notepad Tutorials and they are all working on my virtual device. I am now stuck in the midst of trying to write my own Android app.
My setup:
Windows 7 SP 1 64-bit
Eclipse Indigo Service Release 2
Android Development Tools 16.0.1.v201112150204-238534
Android Virtual Device Platform 2.3.3, API Level 10, CPU/ABI ARM (armeabi)
The app is about as simple as they come - you enter a number, it divides it by another number and displays the result.Here is the code involved:
AndroidManifest.xml:
Code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.android.driving"
android:versionCode="1"
android:versionName="1.0" >
[code]...
By the time DrivingTimeEstimator's onCreate() method gets executed, the Bundle object (savedInstanceState) is null (which I'm guessing is what leads to mMiles being null, which throws a NullPointerException and kills everything).
My app launches the camera to allow the user to capture a picture. Sometimes this causes the OS will kill my App to free up memory for the camera. Once the picture is taken, my app starts back up where it left off using the Bundle I saved in onSaveInstanceState(). My app had a bug where in the code that restores the state. Is there anyway that I can simulate or test this case to make sure I am restoring correctly now? It seems I am having trouble making this happen when I want to test it.
View 4 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 RelatedJust upgraded my phone firmware to 1.6, and it looks like Location objects don't have satellite counts in them any more:
locMan = (LocationManager)con.getSystemService (Context.LOCATION_SERVICE); Location loc = locMan.getLastKnownLocation (LocationManager.GPS_PROVIDER); Bundle extraBundle = loc.getExtras();
extraBundle is null. So, I can't call
extraBundle.getInt("satellites").
I am trying to use Android's LocationManager requestLocationUpdates. Everything is working until I try to extract the actual location object that in my broadcast receiver. Do I need to specifically define the "extras" to my custom intent so that the Android LocationManager before I pass it to requestLocationUpdates so it knows how to add it into the intent, or will it create the extras-bundle regardless when it passes the fired intent to the broadcast receiver?
View 1 Replies View RelatedI have an application that uses a service to create an ArrayList of custom objects (MyObject) every x seconds. I then want my Activity to obtain this ArrayList. I'm currently planning on having the Service send a message to the Activity's handler every time it finishes the query for the data. I want the message to the Handler to contain the ArrayList of MyObjects. When building the method in the Activity to get this ArrayList out of the message, I noticed that I couldn't.
View 1 Replies View RelatedMy android app fetches a JSON structure from the net. It's somewhat large, maybe 2,000 characters in length. I need to store it away when my app gets killed so I can recover it quickly. I've tried saving it to an sqlite database, but that takes about 400ms, kind of long. I wonder if it's bad practice to just dump it into the save bundle:or are we really only supposed to be putting the smallest of items in bundles?
View 3 Replies View RelatedThis is a bit complicated to explain (and my first post), so bear with me please: I am currently trying to figure out the best way of saving my application's state in a bundle on the onSaveInstanceState event (working on a game). My application's state is based on a "world" class which contains various objects. Among these objects there is a creature object which contains bitmaps (Bitmap object)(allowing me to draw the various sprites of the creature when it's walking with more flexibility and accessibility).
Bit of creature constructor Java:
CODE:.................
After looking around for a few hours I found that serializing the world object (and all its sub-objects) was an acceptable way of saving it in the bundle. Unfortunately it appears that we can't serialize bitmaps and considering they're a part of my "creature" I can't seem to see a workaround.
Here come my questions: 1- Am I doing something fundamentally wrong? (not supposed to save bitmaps in objects? supposed to handle bitmaps in a separate class which I don't pass on the bundle and reload my bitmaps when restoring the application? ...) 2- Is there another way of passing my "world" object into my bundle (would using Parcelable work?)
I would like to pass a considerable sized amount of data (~1500 bytes) between two applications in Android where performance and resource allocation is a priority. The data is basically key-value pairs. The rate at which it needs to be passed from one application to another can vary from a trickle to ~50 packets within a second. I figure I can either:
Wrap all the data inside a bundle, and pass the bundle via an Intent from one application to another. I worry about the performance implications of allocating and de-allocating all that memory to store the bundles.
Write all the data to a SQLite database and provide it to the other application via a content provider. Here I worry about the performance implications of writing all that data to disk, and then having to read it back from disk when it is requested. So, which is the lesser of two evils?
When implementing an ActivityInstrumentationTestCase, how do you start the activity with a Bundle of saved state?
View 2 Replies View RelatedI'm trying to prevent the situation where an updated version of my app restores using a bundle written from a previous version of my app. In other words:
1) app v1 stops and calls onSaveInstanceState
2) app v1 saves the bundle
3) user goes to marketplace and updates the app to v2
4) user starts the v2 version of the app
5) v2 version calls onCreate passing the bundle with v1 data
Is that even possible? Do I need to worry about it?
I've recently done quite a bit of work on saving instance state and restoring using parcelables for custom data structures. My problem is that I don't know how to test this functionality on the emulator. I can trigger calls to onPause and onStop for my activity (if I navigate out of it) but never onDestroy. So, whenever my app starts up, it starts with a null bundle. I've never had onCreate with a non-null bundle and I've never had onRestoreInstanceState getting called. how I can test the restore state functionality from the emulator?
