Android :: Creating Background Android Process Using Html 5 API
Nov 22, 2010Just wondering if is there a way to create background task in Android using HTML5 API instead of using native Java SDK?

View 1 RepliesI've been tasked with creating an html form to process SSO login requests for an app. The app developer used webapp, I believe, to load the URL I gave him.
The page loads fine, but for some reason I can not click on any of the input fields or submit buttons. Href links work fine.why the app would not be recognizing the touches/clicks for those html elements, but still allow hrefs to work.
Unforutnately, the app developer is slow to respond and I am wanting to put this project behind me and this is the one thing standing in the way.
The app widget documentation indicates that the "widget provider"being a receiver of a broadcast service may not exist (the process) beyond the completion of the call.If I want to maintain state between two broadcast events, such as say widgetProvider.onUpdate(), can I start a local service and leave it hanging there until my widgets are disabled? If I didn't explicitly stop that service will it be loaded again and resumed when the device wakes up.

View 2 Replies View RelatedI am using a TabActivity (Main) with 3 TabSpecs
I am using Intents for the content of the 3 Tabs
TabA, TabB, TabC for example.
All these tab activities use common data that is stored in SharedPreferences
In the Main TabActivity I have an options menu which has a refresh option.
CODE:.............
This refresh uses an AsyncTask (updateCommonDataFromWeb) to reload the common data from the web.
I need a way to tell the 3 tab activities to refresh their views and rebuild their content from the newly downloaded data.
When the tab activities are first created they load the data from SharedPreferences like so:
CODE:..............
I thought about making a common method on each of the tab activities
like.... reloadViewData()
I thought maybe I could use the activity manager from the Main TabActivity to get the activity of the current tab like so:
CODE:.............
Unfortunately i cant get this approach to work, whilst activity is the correct instance its an Activity instead of a TabA,TabB or TabC
Maybe i've completely taken the wrong approach to the whole thing.
I have also read alot about not using Activities for tab content instead using views.
However I dont know what view to use to replace my <RelativeLayout /> as i cant use my R.layout.* as views.
I have an application that has a widget. In the main application, I have an ad framework (cannot be edited due to license) that is accumulatively leaking approx 1MB every time I exit the application. It appears one of its threads are running in the background (unnecessarily) that will keep its process and these threads will be created again when I launch the application. Is it a good idea to call:
android.os.Process.killProcess(android.os.Process.myPid());
In the onDestroy method of my main activity? Also, would doing this kill my widget's service as well?
Viber itself seems to work fine, however there is a background process it tries to run which keeps crashing. Relevent log info:
Code:

[code].....
Everytime it crashes it causes lots of lags and also audio pops. I'm using Cyanogenmod 10.1RC2 with the Galaxy S I9000.
I am trying to get the list of process running in the background.
View 4 Replies View RelatedI have heavily edited the original text and instead of the how question I am posting the code that produces the effect I wanted, namely a floating menu on top that stays fixed as I scroll whatever is in the middle with a lower menu at the bottom of the screen. Ain't life sweet - Might even work on the iPhone as well.
Why I posted was like I said in the original question. I'm fiddling with creating the initial lay out for a "mobile" application for the disabled, have tonnes of data, dictionary files, icons for the purpose etc. I want to have the app running as HTML to make it as portable as possible, i.e. make it runnable on Android, Iphone, Maemo... whatever.
I got some hints by looking at the example at http://www.quackit.com/css/codes/css_floating_menu.cfm as well as a lot of trial and error and finally minor edits by a paid freelancer.
Below you can find some crude (to put it mildly) HTML/CSS (cut the CSS part and load a style instead in the HTML's you create for cleaner code) but for now, let's look at the prototype concept.
CODE:...........
You can see the working example on your Android device or in your Android emulator http://globability.org/webapp/aaa.html
Need to get the sound working though - but nearly there :)Links to the different web based version and thoughts behind application can be found on:
The project this application springs from can be found on [url] - Look under prototypes (it is the top one under the heading protypes).
I;ve been trying to create a custom button in android using this tutorial - http://www.gersic.com/blog.php?id=56
It works well but it doesn't say how to change the font size or weighting. Any ideas?
There was another question on here and the only answer was to use html styling but you can't change a font size in html without using css (or the deprecated font tag). There must be a better way of setting the pixel size of the font used on buttons?
Sometimes the DDMS in the Eclipse not listing the process.
To do the debug in this condition,
1) Is their any way force the DDMS to list the process?
2) Any command to attach the process from the command line?
At a certain point in my program, when I'm completely done with my service, my activity executes unbindService() and stopService() -- yet the process persists. I can tell that it persists because I run "ps" in "adb -e shell":
CODE:.............
"adb logcat", I can show you the sequence of events:
ACTIVITY: context.unbindService(serviceConnection);
SERVICE: onUnbind();
ACTIVITY: stopService(serviceIntent); & returns true!
SERVICE: onDestroy();
First, my activity calls unbindService(serviceConnection). According to the documentation, unbindService() will "Disconnect from an application service. You will no longer receive calls as the service is restarted, and the service is now allowed to stop at any time." So that is fine, and it is happening.
Appropriately, we see the onUnbind() call happen on the service side. According to the documentation, onUnbind() is called when "all clients have disconnected from a particular interface published by the service." So this confirms the correct service connection is being passed, and that the service is responding accordingly.
Next, my activity calls stopService(serviceIntent), and returns true. According to the documentation, stopService() does the following: "If there is a service matching the given Intent that is already running, then it is stopped and true is returned; else false is returned." Again, this is happening and returning true.
In response, the service's onDestroy() method is called. According to the documentation, onDestroy() is "Called by the system to notify a Service that it is no longer used and is being removed. The service should clean up any resources it holds (threads, registered receivers, etc) at this point. Upon return, there will be no more calls in to this Service object and it is effectively dead."
At this point I expect the process to disappear from the process table. Yet it remains indefinitely. But why?
Also, the process is so persistent that I can bind to it again, and I see that it is the same exact process responding because the PID (process ID) is the same!
So, I decided to give Tridents ROM a try about 10-minutes ago.
I used ROM Manager, backed-up my old ROM, then downloaded Velocity 0.2.
Now, my phone will do nothing, it turns on and shows the red Droid eye, then when it's time to go to the home screen I get pop-up after pop-up saying that "The process com.android.phone has stopped unexpectedly. Please try again."
I have no way of getting on my phone at all, what can I do?
I Just installed a new theme (Live Wire) for my Lithium Mod Rom. Don't know if there is a connection, but when I need to update an app, I get the message something like "process android media process stopped unexpectedly" and it will not allow the update. Everything else works well. I have turned it off for awhile, and have done a battery pull.
View 1 Replies View RelatedEvery 5 minutes this error pops up "Sorry! the process android.process.acore has stopped unexpectdly. please try again." It doesnt actually close anything. It pops up even when im not in an app. So it's more annoying than anything.

Whenever I try to add a contact to my phonebook, before clicking save this message appears: "The process android.process.acore has stopped unepectedly. Please try again."

Another thing is, even though my contacts' names appears in the messages in my inbox, when I click on the phonebook icon, the phonebook is empty...

I'd like to design a security application without having to modify the firmware, if possible (yes I know about "security through obscurity"...).
So since I got the phone on Thursday, at random, I'll get these popup crash messages, that say "The process com.google.process.gapps has stopped unexpectedly" it has a "Force Close" button, which doesn't seem to change anything other than to acknowlege the message.It will happen at random, sometimes while I'm on the home screen, or sending a text message, but more recently, as I was trying to manage & link contacts. When I searched for this message it seemed to be related to people using Gmail, but I always get this message when I'm doing other things and not even touching my Gmail account.

I get the following information: "Sorry! The process com.google.process.gaps has stopped unexpectedly. Please try again".
I've searched around the forums (here and SDX forums) and although it seems the few people that had this issue were able to solve it, my case seems a bit different.
It's different because of the people I've read solving the issue, it was a problem with something they changed / removed with gmail / gmail storage or talk / talk storage. And when they cleared the cache or re-installed the problem went away. Also, it seemed that the same people had a problem with downloading from the market...
Neither of the above apply to me, but yet I'm still getting this FC error all the time!
I was helping a friend with their CL14 Moment out of the box...and went from stock 1.5 CL14 to 2.1 DD03 w/Joey recovery to EclairDD10 and v5 root. I then did the streaming media fix, and then the private app (build.prop) fix (all previously done with my phone no problems). I did all of these update right in a row, and after my last re-boot the FC error (process com.google.process.gapps has stoped unexpectedly) started showing up and won't go away.
The only .apk / odex files I removed were the preloaded Sprint apps
Does anybody have any other ideas on how I can get this FC error to stop? I've tried clearing the cache / data for all the mail / talk apps, rebooted, cleared dalvik cache...
Keep getting this message "The process com.google.process.gapps has stooped working unexpectedly. Any thoughts on what this is and how to resolve?
