Android :: Setting Up Code For Different Runtimes
Oct 18, 2010
I am working on an Android application that is supposed to run on Android 1.5 and later devices. I am using RawContacts.CONTENT_URI enumeration for registering a ContentObserver in my application subclass. Now, RawContacts was introduced in Eclair and running this code on Android devices having runtime less than 2.0, gives java.lang.VerifyError. For older devices, I have to use Contacts.CONTENT_URI.
So to fix this, I've put something like the following in my code:
CODE:.......
I am still getting java.lang.VerifiyErrors.
How do I setup my code for different runtimes?

I was trying to make an app which also had the facility to let user select wallpaper he would like to set. I have managed this by calling the Gallery Intent. Once the user selects a specific image, the data path of the image is returned to me which then i preview to the user by setting the image onto an imageview.
The problem crops up when the image size (and/or resolution) is greater than what android expects. This results in failure of my module.
And as if this was not enough, wen the user tries to select some other wallpaper(and in my test case the "other" wallpaper was also of size >700kb) then the app crashes with the "OutOfMemoryException"...
For Gallery Intent i use:
CODE:............
For setting the wallpaper i use:
CODE:.......
So i have 2 problems to deal with:
How to crop the image before setting it as wallpaper...Cant understand y OutOfMemoryException is thrown, coz none of my image sizes exceed even 1mb... and i guess the VM budget in case Of N1 is 24Mb if m not mistaken...

I have read about using a 'dip' scale rather than just px, this is straightforward to implement in XML. But how do I adjust values accordingly in the java code? For example:
tv.setTextSize(20)
will result in text of size 20 px right? What's the quickest way of making this 20 dip, other than adding a resource?

I'm trying to have my home-screen application register itself as the default home-screen so the user is not prompted with the IntentResolver's list of all the available home-activities.
This is my code:
CODE:.................
I have the android.permission.SET_PREFERRED_APPLICATIONS set in the manifest. After executing the code above, the logs claim things have been added like expected (same logs as when I tick off "Make default" from IntentResolver's list). However, when I proceed by clicking home, the list still shows up and the logs say:
CODE:.....................
So it seems the resolver deletes the default entry. Am I doing something wrong, or is this a security measure? What are the ideas behind this?

I'm playing with the alternative Home app that comes with the SDK.
I can set this as default for 'Home' action.
I can unset this by -->Setting->Manage Application->My Alternative Home-> "clear defaults"
Question:
How to do this "clear defaults" by code?
I've browsed the forums but cannot find an answer.

I'm currently learning android and java, and I am having some issues with importing a java file.
I am working with the time and date example in the android api demos, and I want to put all the code relating to creating the time and date dialogs setting the values etc into a separate java file, and in my main java file run when the application starts, just declare the buttons and onclick events.
What is the best way to do this? Do I need to put all the code inside a class(that extends activity) or method? How do I use this inside my main class. Code...

In an effort to reduce duplication, I have my app's workspace split into 3 projects:
Main (A library project, where all of the common code lives)
Free (To make the free version)
Paid (To make the paid version)
Behavior in the free version and the paid version must differ sometimes. How can I "call into" the final projects from the library project? Here is some sample psuedo-code to illustrate my question: Code...

I can't, for the life of me, figure out how to set this up. I don't know what I'm supposed to put in the "Hostname or IP" field and I have no clue what my port is. And this also has a place to put a username and password. Do I just put anything?

I'm having trouble setting up the Android SDK. I've set up Eclipse before but it didn't work, so I uninstalled it, but I'm trying again.
Does Eclipse need to be extracted to a particular folder for it to work? Where should I extract to?

I recently switched computers, so im trying to reinstall it and im doing so by following the steps in the Pre-requisite section of this guide: http://androidforums.com/all-things-root-eris/53963-guide-stock-1-5-latest-root-2-1-a.html
It says that I should be getting a "#" when i type adb shell since I'm already rooted. Instead, I'm getting "sh-3.2#". Is it safe to continue?

This seems like an obvious thing, but I can't find any way to do it.When I put my phone in the car dock, instead of auto-launching the official "car dock" application, I want to launch an app of my own choosing. (in this case vlingo)I can find various apps that specifically replace the car dock app, but that's not what I want, I want to use vlingo (which doesn't seem to have that option by default)Just to be clear, I don't want an app that gives me an icon I can click to launch vlingo, that would defeat the purpose as I can already click the icon on my home screen to launch it if I want.So how can I set what program launches when I drop it in the car dock?
