user interface - How to design android UI depending on different android OS versions -

-

i have 2 different android tablets have different os versions.

one kitkat(4.4.2) sdk 19 , other jelly beans(4.1.6) sdk 16.

my question how design ui in manner fits both os. designed ui based on sdk 19 kitkat. company says distribute app on jelly beans(sdk 16). when run app same code on lower version(sdk 16), see images not fit on screen. see images stretched out. way designed didn't provide ui images ldpi, mdpi, hdpi, , on used hdpi since assume jelly beans tablet(galaxy tab 2 10.1) has same resolution(1280x 800) galaxy tab 4 10.1) has. isn't there ways can write designer code(xml) able fit ui both versions? or should write separate ui layout fit both versions? according research android developer site, recommended should provide different size of images(ldpi,mdpi, hdpi, , on). since not differentiating size of tablet(10 inch screen), assume using 1 size feature enough.

would please me on this?

thanks,

i want check scene image against 2 train images. that, detect features , compute descriptors of both training images. before detecting, computing , matching scene image, delete matches of train1 , train2. because these matches won't facilitate matching of scene image train1 , train2. so, match train1 train2 , vector of matches trainidx , queryidx. how can delete these matches in keypoints-vector , descriptor matrix of train1 , train2? best regards, dwi i have done below: std::vector<cv::keypoint> keypoints[2]; cv::mat descriptor[2]; std::vector< cv::dmatch > matches; /* write code generate keypoints, descriptors , matches here... keypoint[0] -> train image 1 keypoints keypoint[1] -> train image 2 keypoints descriptor[0] -> train image 1 descriptors descriptor[1] -> train image 2 descriptors matches -> matched between train image 1 , 2 */ // logic keep unmatched keypoints , corresponding descriptor

i used nvidia sdk bitonic sort , works great me. 32 bits (uint) need ulong keys. have typically 2^14 keys @ time , power of 2. searched on not find kernel designed ulong. i tried modified nvidia sdk bitonic sort using ulong keys not work. kernel not crash after de call clenqueuendrangekernel got error : cl_invalid_command_queue can tell me how modify bitonic sort or radixsort, or can sort ulong keys? i running nvidia quadro 4000 opencl 1.1 cuda 6.5.20 full_profile used original nvidia sdk bitonicsort.cl i used"ulong" keys , value input , ouput instead of "uint" thanks helping i made work-around suit need. used 30 bits of key , 18 high bits of value sorting. changed comparators (2 lines): '#define mask 0xffffc000 // suit need from this: if( (*keya > *keyb) == dir ) this: if(((*keya > *keyb)||((*keya == *keyb)&&((*vala & mask)> (*valb & mask)))) == dir ) it works fine. but, still, it's work-a
