<p dir="auto">What's the purpose of this, or is one of them just an outdated relict ?<br>
Who knows it ?</p>
<p dir="auto">If it's a pointless double code, I vote for a deletion to reduce confusion. But which one ?</p>
<h2 dir="auto">Eclipse ?</h2>

<p dir="auto">For me it looks like the one with **/<strong>gradle</strong>/AndroidManifest.xml is the right one</p>

<p dir="auto">When I was trying to look for the header files for different OpenCV functions via Google, I really had some troubles as a beginner. I wish the OpenCV manual could be more like what CPP reference website have so that users could know what header files to use immediately. For example, on <a href="https://en.cppreference.com/w/cpp/io/basic_stringstream" rel="nofollow">https://en.cppreference.com/w/cpp/io/basic_stringstream</a>, it specifically tells you the function is "Defined in header ". While for OpenCV functions, it is very vague. For example, on <a href="https://docs.opencv.org/trunk/d4/da8/group__imgcodecs.html#ga288b8b3da0892bd651fce07b3bbd3a56" rel="nofollow">https://docs.opencv.org/trunk/d4/da8/group__imgcodecs.html#ga288b8b3da0892bd651fce07b3bbd3a56</a>, the module name was hidden in the url, which was not so obvious to the new users.</p>
