https://devzone.nordicsemi.com/f/nordic-q-a/1538/can-t-compile-uart-appI downloaded the source for the Android UART app, hoping to hack it into something I can use to test my gadget. But it&#39;s incomplete: it fails with the message: Missing required library: &#39;C:/Nordic Semiconductor/Android/adt-bundle-windows-x86_64-20130729en-USTelligent Community 13Fri, 07 Feb 2014 18:46:58 GMThttps://devzone.nordicsemi.com/thread/6827?ContentTypeID=1Fri, 07 Feb 2014 18:46:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f5a9539b-a5e0-44d5-b477-9dc00b30bdcbLee Daniel Crocker<p>Ah...found it in sdk/extras/...</p> <p>I should have known that...I&#39;m not, as you may have guessed, an experienced Android developer (though I am a sane one :-)</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/6826?ContentTypeID=1Fri, 07 Feb 2014 15:13:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7bbebb6a-71b0-49da-8c59-82408c02794bHung Bui<p>Hi Lee,</p> <p>I got your question on support portal, but I would suggest we continue here since it maybe useful for others.</p> <p>[i]android-support-v4.jar library is needed to use the LocalBroadcast class.You can find the library in the Android SDK by default at: adt-bundle-windows-x86_64-20131030\sdk\extras\android\support\v4</p> <p>Where adt-bundle-windows-x86_64-20131030 is the folder you get when installing Android SDK. [/i]</p> <p>In your case you don&#39;t use windows but the library should be included in the SDK bundle for other platforms.</p><div style="clear:both;"></div>
