Android :: OTA Configuration Supported By OS?

Oct 6, 2010

I would like to know if the Android handsets can be configured Over-The-Air; in other words, if they can be configured for settings (such as GPRS , WAP or MMS ...) using OTA. If yes, do they support OMA CP provisioning? Is there an XML example that can be used to configure the Android devices?

Android :: Best Way To Add Configuration UI To Application?

Nov 24, 2010

I have a simple Android application that loads a page in a WebView, then most of the real work is done by the server-side scripts. Everything is working great, except that I currently have the page URL hard-coded in the Android application, sort of like this:

This was fine until this morning when I was asked to to make it so that the user is prompted to enter the URL the first time the application run, and the URL that is entered by the user is then saved and used automatically by the application from that point onward. I was also asked to make it so that the user can change the URL if they choose to do so. The reason I was asked to do this is so that users can install the server side of the application on their own servers and my Android application will be able to connect without me having to write a custom version for each user, with their URL hard-coded into the application.

I am unsure what is the best way to handle this in Android. It seems that I probably need to add some type of configuration interface to the application that is shown by default on the first run, then only when the Menu button is pressed on the following runs. From this configuration interface I guess I would then get the URL from the user and serialize it for future use. What is the best way to accomplish this?

Android :: Juice Defender Configuration?

Jul 19, 2010

I've only owned an Android for 6 days (Samsung Galaxy S i9000) and one of the first things I installed was Juice Defender, having used iPod Touch extensively, I know how heavy on battery things like WiFi can be. Anyway, JD makes the phone really really leggy. It can take a minute sometimes (literally, 45-65 seconds) for the JD screen to come up when launched. Similarly when waking from sleep it takes ages for the data connections to become active again. Have I misconfigured JD? Is it really this slow and creates this much lag? Does it just not like the (fairly new) i9000? I've just uninstalled it there right now (left Ultimate Juice on) and the phone is much snappier. It's like using it for the first time. Which, considering JD was installed in the first half hour of my owning the phone, it kind of is. What I really wanted was the WiFi on/off according to cell tower location data so I can have it go on and off when I leave the house. Guess it's no real biggie. Having limited background data (e.g. the 2 mins per 15) is handy too. Are there any other apps which have JD functions - even if more limited in scope - that I can try?

Android :: How To Retrieve Current Keyboard Configuration?

Feb 16, 2009

How can I detect if the G1 keyboard is hidden or open at application startup? My app always runs in landscape mode, but I can only find how to detect keyboard configuration *changes* (through onConfigurationChanged()). So how can I retrieve the current keyboard configuration (open or closed) at application startup?

Android :: Force An Update In A Configuration Activity

Sep 29, 2010

I'm writing a widget with a configuration activity which calls the following method when its OK button is clicked:


This is almost verbatim from the documentation. widget_id holds the widget ID that was dug up during the activity's onCreate().

When I place an instance of the widget on the home screen, I've verified that I get the expected sequence of events:

onReceive() gets an ACTION_APPWIDGET_ENABLED if it's the first one.
onUpdate() gets called (in which I detect that the widget isn't configured and draw something as a default action).
The configuration activity appears.
When I press OK, the ok() method above gets called.

The method gets all the way through to the finish() and the configuration activity goes away, but there's no call to onUpdate() or onReceive() after this point. (The widget itself has no updatePeriodMillis.) I end up with a widget on the screen that has the results of my default action but never gets updated.

If I set the widget up without a configuration activity, it gets updated when created and everything works as expected (just without the configured bits).

I am still learning bu find Android the cool platform for allot of useful applications. I have written a Service for doing GPS tracking and it consists of a Service and a Control activity to manage, monitor and configure the service. I am looking for the preferred way for the Control Activity to define settings for the Service, things like IP address and Update interval. I envision something like a Registry on windows where these settings can be shares and updated.

Android :: Smartphone Memory Configuration - Inbuilt ROM And RAM

Jul 17, 2010

Smart-phones have built in ROM and RAM separately. Also a few phones has virtual memory support too. I would like to know what these memories are basically used for. I understand that RAM is available to user processes. But why do they have a big chunk of ROM? E.g. The wiki page for Droid Incredible says

1 GB ROM (748 MB free to user) - what's this free to user?
plus 8 GB moviNAND - typically used for data storage

Android :: Keeping Service Alive Across Configuration Changes

Apr 7, 2010

The default way configuration changes (i.e., rotates) are handled is to destroy the activity & recreate it with a new one. What is the recommended way to handle these changes in an activity that binds / unbinds to a service (that is possibly heavy/slow to start)? When the activity gets destroyed, it unbinds & causes the service to be destroyed. When the new activity is created, it binds & recreates the service.

The only choices seem to be:
-- override onConfigurationChanged in the activity. Feels ok, but non - conformant.
-- explicitly start the service & only stop it when the last activity gets an onDestroy that's not due to a config change (i.e., there was no call to onRetainNonConfigurationInstance). Feels icky.
-- explicitly start the service & don't stop it until some amount of time after the last unbind. Ickier.

On a related note, what happens between activity switches within a process, where the first activity (A) starts the next activity (B) & then calls finish() -- is there a guarantee that B.onCreate is called before A.onDestroy? If not, and the activities share a service, the same issue of keeping the service alive during this window exists, but with only the icky workarounds.

Android :: Deploying Custom Configuration With Application

Aug 2, 2010

I have developed an App that talks to a set of web services. Because the App is used in different environments and for different purposes, I would like to provide a way to automatically deploy a configuration alongside the App that contains the settings for the environment (url of the locally hosted web services for example) and App settings (such as a timer period for talking to the web services). It would be tedious to have a UI for this and have to do it on every device post installation. Things I have tried and why they didn't meet my requirements:

*Raw Resource: If I unzip the apk and change the settings file, it becomes invalid as I need to resign the apk.
*Reading straight from the apk with ZipFile/ZipEntry: Device complains upon installation that the config file is not signed.
*PreferencesActivity: Requires device side UI; It would be tedious to have a UI for this and have to do it on every device post installation.

Android :: Dialog Survival Over Configuration Change

Mar 4, 2009

Flipping between landscape and portrait is causing me a problem with dialogs that are active at the time of config change. The dialogs survive (which I think is good), but I have the problem that some of my dialogs contain dynamic content which would need to be refreshed in the dialog views. All that content disappears from the dialog views after the config change.

I thought it would be easier to do a dismissDialog() on restoration in onCreate(), letting the user press the button that shows the dialog. I successfully save and recover the dialog id, but when I attempt to dismissDialog(id) I get an IllegalArgumentException: no dialog with id 1 was ever shown via Activity$showDialog. Ok, so that doesn't work, and I still have that messed up dialog up on the screen that I want to get rid of. How can I do that? Are there any other reasonable alternatives?

Android :: Icon Configuration Like Crazy Home

Aug 25, 2010

I was wondering if anyone who has tried Crazy Home knows of any application that allows you to switch icons from theme to theme like the Crazy Home launcher. I know of and have Bettercut, but that only allows you to create your own, or replace using a downloaded icon pack. But the crazy home app allows you to choose a theme, then use icons from another theme which bettercut does not allow. It also lets u change and icon to the theme icon. For example the gmail icon is default, but the email icon is themed, it offers the ability to change the gmail to themed.

Android :: Configuration Changed And Destroying Activities

Jan 9, 2010

I read up on how Android handles "configuration changes" - by destroying the active Activity.The first question I really want to know from Android Team - why? I would appreciate an explanation on how the reasoning went, cause I dont get it =)In any case, the fact that it acts in that way puts us all, as I see it, in a world of pain.Lets assume you have a Activity which presents a number of EditText:s, checkboxes etc. If a User starts to fill that form with text/data and then changes orientation (or get a Phonecall), then all input the User made is gone. I havent found any way to preserve state. That forces us to make extremely painful coding to not loose all data.

Android :: Add Widget Configuration Activity To Launcher?

Oct 17, 2010

I have a widget with a configuration activity.

Currently the configuration launches when you click on the widget.

I want to add the configuration as an app icon to the launcher.

The problem is that when the configuration launches on click, I get a specific widget id , so each widget instance can have a different configuration.

What will happen if I start the activity from the launcher?

I wont be able to show multiple configurations on the same activity.

Android :: Instance-specific AppWidget Configuration

Android :: Configuration Changed / Orientation From Portrait To Landscape?

Nov 10, 2010

While working on orientation change I have found that the onConfigurationChanged is not getting called when changing the orientation from portrait to landscape.But when I am changing from landscape to portrait the method is getting called. Is it the correct behavior because the onConfigurationChanged should by called whenever we are changing the orientation. (android:configChanges="orientation")? I have also found one strange behavior or error, When we are changing from portrait to landscape orientation the string value is displayed correctly(automatically by android system) but when in am changing the orientation from landscape to portrait the same string is displayed(i.e the string in landscape mode).The expected behavior is the string id specified in the portrait mode should be displayed.Is it an platform bug or something wrong in my code/programming.

Android :: Widget Configuration Activity - Update Request

Sep 18, 2010

I'm having an issue with a config activity for a widget. According to the dev docs, if I specify a configuration activity than the onUpdate method of the AppWidgetProvider doesn't get called until after you request an update once you've completed the configuration activity. For me its happening in reverse, the onUpdate method of the AppWidgetProvider gets called first, followed by the configuration activity. Then the onUpdate method is never called after completion of the config activity even though I request it explicitly. I tried with level 4 and level 7 API, same result. Here is some of the source:

<?xml version="1.0" encoding="utf-8"?> <manifest
android:versionCode="1" android:versionName="1.0">
<application android:icon="@drawable/app_icon" android:label="@string/app_name">
<activity android:name=".SWidgetConfigure">
<intent-filter> <action android:name="android.appwidget.action.APPWIDGET_CONFIGURE" />
</intent-filter> </activity>
<receiver android:name=".SWidgetProvider" android:label="@string/ widget_name">
<meta-data android:name="android.appwidget.provider" android:resource="@xml/swidget_info"/> <intent-filter> <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
</intent-filter> </receiver>
<service android:name=".service.PUpdateService" />
</application> <uses-sdk android:minSdkVersion="4" />
<uses-permission android:name="android.permission.INTERNET" />

swidget_info.xml: <?xml version="1.0" encoding="utf-8"?> <appwidget-provider
android:minWidth="294dp" android:minHeight="72dp"
android:configure="" >

I can include source of the onUpdate method from the AppWidgetProvider activity and the onCreate method of the configuration activity if necessary, but they are both being called find its just the order they show up on the emulator is wrong.

Android :: Save Configuration Value As Integer In Preference Activity?

Sep 16, 2010

Is there a way how I can tell the Preference Activity that value should be saved as integer? So far my all values are saved as strings... I can limit input to integers via XML easy:

<EditTextPreference android:key="SomeKey" android:numeric="integer" />

but it is still saved as string and later trying to getInt("SomeKey") on preferences object I always get java.lang.ClassCastException: java.lang.String.

Is there a way that EditTextPreference value would be saved not as string? Or maybe I should use some other type of Preference for numeric input?
