Just released a brand new version of MediaDroid.  Thanks to some reverse engineering of the Android Image Gallery, I’ve been able to greatly increase the performance and stability of the app.  Hopefully I’ll be able to get into the specific changes (for all the Android developers out there) in a later post when I get a little more time.  Also, improved the button icons thanks to my son’s (OK…they where mine first) Crayons (TM).

Already have plans for some more features (filtering the image buckets shown in the Image Gallery) and with this re-write out of the way I think I’ll be able to get the next version out sooner.

Cheers, and thanks for all the support from the current users of MediaDroid, it’s great to hear all your feedback…good and bad!!

As I’ve been alluding to in my Twitter feed, I’m on the cusp of deploying a new version of MediaDroid, huge re-write to image gallery, but hopefully I’ll get a post about that out later.  Anyway, the previous way I was marking the images to be included in the albums was to have a combo view with a check box and a thumbnail of the image.  Although this works, it takes up a lot of screen real estate and isn’t terribly efficient.  The next version of the image gallery I wrote extended the Android ImageView class and although this solution isn’t much more efficient (the solution for that is in my newest version), it certainly increases the number of images viewed at a time.

Here’s a quick code snippet to determine if the GPS is on, and if it isn’t go to the Setting screen allowing the user to turn it on.  Android does not allow a 3rd party app to automatically turn the GPS on/off as of 1.5, a “feature” discussed extensively on the Android Developers Forum.

I posted a new version of both MediaDroid and Message Drop to the Android Market this morning.

The new version of MediaDroid fixes the reboot bug.  It’s not as elegant as a fix as I’d like but it does work.  FYI to any developers, the SD Card isn’t necessarily mounted when the ACTION_BOOT_COMPLETED event is broadcast.  I used a CountDownTimer to wait 30 seconds after my BroadcastReceiver is called, then I’m able to access the files on the SD Card.

I added a couple features to Message Drop and fixed a few bugs.  The new features are spelled out on the Message Drop page  and include a new Setting for assigning the “Blank Tag” and a mode helping you build bulleted item lists.

My plan is to switch back to MediaDroid and perform some much needed polishing, and I ran into a Force Close that I haven’t been able to track down yet.  Always more to do!

I’ve been playing around with searching for contacts on the Android platform and thought I’d pass along a couple things I’ve learned.

One thing I’ve found out is that some of the classes from the books I’ve been using as reference have been deprecated.  Apparently, instead of using People.NUMBER, which has been deprecated for future support of multiple accounts, I should use the ContactsContact set of interfaces to get the contacts name and number.  Guess I’ll be upgrading to the Android 2.0 sdk sooner then I thought.  Although according to this forum thread the previous interfaces used to specify contact column, such as People, are still supported and will access contact information from the “primary” account.

Another cool thing I figured out was how to have the phone pad soft keyboard attached to an EditText widget.

It’s one of those, it was so easy I’m ashamed I didn’t know it, but then again, the SDK is large enough to where it’s hard to know ALL of it.  Anyway, all you need to do is define the “inputType” attribute value for the EditText widget which captures the phone number.

   	<EditText android:id="@+id/phone_nbr"
		android:layout_width="fill_parent"
		android:layout_height="wrap_content"
		android:inputType="phone"
		android:singleLine="true" />

Now, when the phone_nbr EditText box is entered, the phone pad comes up for data entry instead of the default Android soft keyboard.

There’s still many aspects of the Contacts API I haven’t investigated yet, but hopefully with the new apps I have the opportunity to work on, I’ll have lots of time to learn more about them.

I’ve finally got Message Drop to a point where I feel it deserves a release.  Message Drop is a re-branding of Note To Me with a built in email client and a couple new features.  I’ll be getting screen shots up soon on the Message Drop page along with some more information, but just wanted to put the word.

There’s a trial version available, but if you find it useful I’d greatly appreciate it if you’d help my development effort and purchase the 1.99 version.  By the way, if you purchased Note To Me already, I’d be more then happy to refund your money if you email me an address that I can send the refund to.  I promise not to use your email for spamming!

I would greatly appreciate any comments you may have about Message Drop, Cheers!

Are you utilizing the full potential of AlertDialog?  I had no idea it was so versatile until I starting playing around with it recently.  I knew you could use it for a yes/no dialog for your mobile application, but I didn’t know it could also be an About dialog.  The API makes it really easy, although it doesn’t seem like the setPositiveButton() method is in the Android documentation.  The code snippet below cuts it down to the bare minimum.  It appears that a null can be passed instead of an empty OnClickListener and the action simply closes the window…which is the desired effect.

AlertDialog.Builder ad = new AlertDialog.Builder( this );
ad.setTitle( "About My Mobile Application" );
ad.setMessage( "This text explains My Mobile Application, thanks for " +
                       "purchasing it from the Android Market!" );
ad.setPositiveButton( "OK", null );
ad.show();

I’ve recently cleaned up a bunch of my code with this simple Dialog. And next I may have to look into the FrameLayout feature mentioned in the Android documentation.

With the successful completion of my latest contracting gig, I find myself with the opportunity to investigate freelance work.  I’ve decided to take a couple of weeks to see if I can move into freelance development for the Android framework instead of looking for a full time position.  I have no idea if this will work and in the end I may have to start pushing my resume again, but I’m willing to try.  Don’t get me wrong, if the right opportunity for a full time position cames along, I’m certainly interested.

So, if you or someone you know needs a Android developer, I’d love to hear from you.  Email me at michael@mgmblog.com and I can send you my resume and let you know the initial rates I’m looking for.

Also, if you are currently freelancing (for either the Android or iPhone market) I’d be grateful to hear what has worked for you when it comes to looking for gigs or working with your clients.

Here’s some links I still have laying around in my RSS reader I still need to get to, hopefully you may find some of them useful.

How to Defeat Burnout and Stay Motivated  from Zen Habits

I’ve been meaning to get a post out about the Android apps I’ve purchased since I first asked people to buy more Android apps.  I put out a couple emails to companies and developers who’ve built apps for the Android Market and Bendroid was the first ones to respond.  I’m not sure if I’m going to request questions for all the apps that I review, but I thought it’d be a cool way to start.  It also gives me a way to ask successful Android developers questions that will hopefully help me be more successful also.

Onto the review!
