How do you get the default value of an Android preference defined in XML?
Context: I don't want to repeat the definition of the default value in both the code and the preferences XML.

implicit intent with class name as action defined in intentfilter. is not working. Only it it is defined as "android.intent.action." it is picked up ? is it so ?
I have app A with the following in manifest.xml file
CODE:.............
In app B, i tried to call the activity in A using below code.
CODE:.............
This code works. But not above line.
By default, when in DialogPreference you press back button, it mimics that you've pressed NegativeButton. I'd like to override that but can't find an easy way except to recreate DialogPreference from scratch (which at the moment seems like an overkill), because I'd like that PositiveButton set something, NegativeButton to unset something, and back key to leave things as they were (i.e. to not unset something). I've even tried to override showDialog() but: a) its not simple, b) I don't think I should mess too much with internals of OS supplied code like a bunch of private "m" variables.

Where is the right place to specify general user-defined properties, like a host address or a service mail address ? The properties should be accessible from my activities.
I would like to specify such attributes within the AndroidManifest.xml, but there seems to be no elements available for user-defined properties. So the only way may be to put such properties into a resource file as strings or to hide them into the source code...
I would like to use self defined Environment variables in my source code.
I use System.getenv() to do this and the code line looks like this. Log.d("MyTest","== MyEnv " + System.getenv("AP") + " ANDROID_ASSETS:" + System.getenv("ANDROID_ASSETS"));
Before I execute my code I define my AP variable with export: export AP="12345" and the this is my output of set command
ANDROID_ASSETS=/system/app
ANDROID_BOOTLOGO=1
ANDROID_DATA=/data
ANDROID_PROPERTY_WORKSPACE=9,32768
ANDROID_ROOT=/system
AP=12345
Then I execute my code and I get this line from logcat
D/MyTest( 5363): == MyEnv null ANDROID_ASSETS:/system/app
The value for my defined Environment variable is null. Any suggestions on why it didn't work?
In my android application that is now working fine, I am sending custom SMS from a user to other one.
Once I detect the SMS come from my application, I do my stuff with the message and everything work fine.
But now, I do not want the SMS application to detect this message as it is totally useless for the user.
So what I would like to do:
As soon I receive it, I get the text and avoid the system to get it ( or at least stop the notification for this message)
Any Idea on how to do? code....
I am working on an application where I am saving the state of an application in an ArrayList. Now, to save this state, I tried to use Serialization. But, somewhere in the user defined object, I am using Button, which is not letting me serialize the entire object. I wanted to know, is there any other way of saving this array list between onPause and onResume? I even tried onSaveInstanceState, but it doesn't have support for Array List.
View 1 Replies View RelatedI defined a white color in mycolors.xml under res/values as below:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="my_white">#ffffffff</color>
</resources>
In my code, I set the text color of a TextView as the white color I defined:
TextView myText = (TextView) findViewById(R.id.my_text);
myText.setTextColor(R.color.my_white);
But the text in the TextView turned out to be a black color. When I use @color/my_white in layout xml files, it works fine. I check the generate R.java, and see: public static final int my_white=0x7f070025;
I have to dynamically add a list of views (the views use RelativeLayout). Can I do this by specifying the view definition in xml and instantiate multiple objects off it? This gives the usual benefits of separating the view part from the code (for e.g., making it easy for the UI guys to alter things) or Is going the ArrayAdapter the suggested/only route?
View 1 Replies View RelatedI have a service that is running within the context of my application. It gets invoked at the start of the activity and then gets update when new data is inserted or deleted from the database. The problem is that everytime I start the activity , it restarts the service. As you may have guessed - not a very intuitive design. Therefore I was wondering if there is a way to determine if the service is already running before starting it. I know I can bind to the service but I do not want that since the main activity needs to exits after the database operation is completed. I know for system services, you can get the service details from the application context. How do you do it for user defined service?
View 3 Replies View RelatedI'm developing an Android application that I'd like to be compatible with 1.5 (SDK version 4).
I'm testing the application on 2.2 (SDK version 8).
To do this, I'm including in the manifest file the line <uses-sdk android:minSdkVersion="4" android:targetSdkVersion="8" />
I thought this would allow me to use the newest manifest elements and APIs, but I'm getting a compile error whenever I try to use them. For example, I try to define the element installLocation to allow the app to be installed on the SD card, but Eclipse gives me the error
No resource identifier found for attribute 'installLocation' in package 'android'
Is there something else I have to do to get this to work? If I can't get this to work, what benefit is defining targetSdkVersion?
I'm trying to use a color defined in a stlyle in a selector but it is causing a Resources$NotFoundException.
First I added a new attribute to attr.xml:
CODE:..........
Then I defined that attr value in styles.xml:
CODE:..........
Then I tried to use that attr in my selector definition:
CODE:................
Lastly, the activity uses the ThemeNoTitleBar style theme in the manifest.
I've also tried creating a color in colors.xml and having it use the new attr but that also fails.
I'm obviously missing something but am not sure what to do to fix it. My intent is to create multiple themes and have the selector use the color in the currently selected theme.
I'm currently developing a simple 2D game for Android. I have a stationary object that's situated in the center of the screen and I'm trying to get that object to rotate and point to the area on the screen that the user touches. I have the constant coordinates that represent the center of the screen and I can get the coordinates of the point that the user taps on. I'm using the formula outlined in this forum: How to get angle between two points?
-It says as follows "If you want the the angle between the line defined by these two points and the horizontal axis:
double angle = atan2(y2 - y1, x2 - x1) * 180 / PI;".
-I implemented this, but I think the fact the I'm working in screen coordinates is causing a miscalculation, since the Y-coordinate is reversed. I'm not sure if this is the right way to go about it, any other thoughts or suggestions are appreciated.

View 3 Replies View RelatedHave been a long time user of Outlook and Blackberry and store a lot of information in the User Defined Fields. Those fields seem to have been eliminated from all of the Android Contact Apps. I don't see them in Motorola Corporate Sync, Touch Down or Moxier Mail. Am I missing something, can't believe the developers of Android apps would just skip those fields. Any App that I can store and sync those fields. Google Contacts has the fields. I have just upgraded from a Blackberry Bold to a Verizon Droid Maxx. Love the big screen on the phone, struggling with the touch keyboard and really struggling with losing half of my contact information.

I am writing a adapter for a specific app, the problem I met is:
I have only 1 listview in main.xml, and the row style is defined in file_row.xml. If I simply use list.setAdapter(new ArrayAdapter<String>(this, R.layout.file_row, R.id.file_name, items)); where items is a ArrayList<String>, everything works well.
But if I use my custom Adapter, say, list.setAdapter(new MyOwnListAdapter(this, filename)); and in the class of MyOwnListAdapter, the code has been simplified as
CODE:................
But I always met the problem which is:
CODE:.........
I thought the self-defined Adapter class actually has only one line of valid execution, which is super(context, R.layout.file_row, R.id.file_name, filename_list); It's essentially identical to direct calling of list.setAdapter(new ArrayAdapter<String>(this, R.layout.file_row, R.id.file_name, items)); Then why I always got this error if I call my own Adapter?

I have a PNG file that is 32x32 pixels. I use 8 of these as drawables in a row for my app. These drawables are not in the hdpi, mdpi, or ldpi folders. I've found that when starting any of the 3 standard size emulators, the screen view with all 8 drawables looks pretty much the same.
I note that the ldpi emulator I'm using (QVGA) has a resolution of 240x320. 8 x 32 = 256, so since I can see all my drawables (and space in-between) I'm betting something is changing their size.
I've read the Supporting Multiple Screens document at the Android developers page, but I still don't understand what is actually happening. Could you put your own words to explain what is happening to the size of my drawables and how the SDK knows to automatically modify them?
I am building a web app, which is intended to run on the Android browser. When I have a webpage that contains any kind of viewport meta tag, like this:
<meta name="viewport" content="width=400"/>
My webpage crashes on ajax calls. It happens when using the emulator, the actual browser on my nexus one, and on a droid (all running Android 2.1). Without the meta tag, the ajax calls run as they should.
I would automate some simple task (such start BT every day at 1 PM...and so on) some times ago I had an App that does it. But I don't remember the name.
