OpenSense SDK Update Available for Download

It’s hard to believe it’s been over three months since Mobile World Congress in Barcelona where we announced some exciting new updates to the HTC OpenSense Software Development Kit (SDK).  Based on your response to that post it’s clear that you’re excited about the chance to build more applications that run on our platform.

Well, the time is here and we’re excited to announce these new APIs are available in the latest release of the SDK at htcdev.com!  Now you can download the update and begin implementing your own innovative new apps that plug into features like the Sound Enhancer, Lock Screen, new Common Controls or Media Link HD (coming soon).

For example, if you want to your app to check for the Sound Enhancer API and then set a click handler to start it up, you can do this with only a few lines of code:

* Sets the click listener of passed in View to launch HTC Sound Enhancer if possible.
* @param enhanceSoundButton View to set click listener on
* @return true if the click listener was set

private boolean setHtcSoundEnhancerOnClick(final View enhanceSoundButton) {
final Intent enhanceSoundIntent = new Intent(

// Check if API is supported.
final List<ResolveInfo> activities = getPackageManager()
.queryIntentActivities(enhanceSoundIntent, NO_FLAGS);

if (activities.isEmpty()) {
return false;

// Call it on click.
enhanceSoundButton.setOnClickListener(new OnClickListener() {
public void onClick(final View view) {
return true;


This is really the essence of the API.  It’s clear, concise, and won’t take a lot of development cycles to bring a nice differentiating feature to your app when it runs on an HTC device.

We’ve also updated the Developer Center section of the HTCdev website to include new sample code, like the one above, and tutorials to help kick-start your development process.  If you’re starting from ground zero and want to know how to get started with Android development, you can always begin with the Orientation to Android Training as a launch point for your development needs!

At HTCDev our goal is to provide resources for those with development experience, but also to create new developers out of many of you who have been ‘thinking about writing an app.’ We know there’s a lot of you out there eager to start coding and put your creative juices to work.  Our enthusiastic group of Developer Evangelists is here for all your mobile development needs, so don’t be afraid to reach out to us!  Follow us on Twitter at @htcdev and any comments or suggestions are welcome.

Once you’re finished coding, click here to tell us about the awesome app you’ve built!

    The currently public APIs don’t support complete custom skinning at the moment. They do allow apps to offer users customization to the lock screen appearance and behavior, however. User choose to use these from their settings app, in the personalization section.

      Hi Narendrea. Nothing has been announced re changing the One V from Sense 4.0a. I’ll forward that it is being requested to the right people, though. Thanks for the interest!

    Hello HTC Guys,
    I ready somewhere that “Media Link HD” won’t work with HTC One V. Is that true, that would be sad. 🙁

    You guys could allow just the Mirror mode (whatever comes on phone comes on big screen)… Leave Dual Mode if that is too intensive.


    • Lance Nanek

      Hi Ramu. Some basic functions like playing movies, music, and pictures to the MediaLink HD will be supported on One V in the future, although not mirror mode.

    After updating my HTC One V, Sound Enhancer for Beats Audio is disappeared. No more presets. Why did you remove this feature?

    Hi, the day I bought a HTC phone back a few months ago, I have fallen in love with the user interface and the style symbol u people provide to this phone . Not only hardware but the software say sense is of top notch. Well could you guide me as I want to pursue my career as an app developer is there any way I could develop apps For HTC, I’m serious about it and would love to work with HTC in near future. I would definitely check new open sense SDK ,

    When will ICS be available for Vivid?

    • http://twitter.com/LanceNanek Lance Nanek

      Hi Michelle, ICS update for Vivid is already out. Have you tried the “Check for Updates” option in your phone’s software settings? Are you sure you aren’t using a custom ROM?
