java - unable to find class referenced in signature (Lorg/shaded/apache/log4j/Logger;) after upgrading Firebase for Android -

-

when save firebase data storage, getting following errors email , password registration fine in login&auth section. using java, android. spent 3 hours cannot fix problems (maybe new firebase android update?).

here proof email/pass working:

            firebase f = new firebase("https://myapp.firebaseio.com/");              firebase userdata = f.child("user");             //save login&auth of email , password success             userdata.createuser(emailaddr.gettext().tostring(), passwd.gettext().tostring(), new firebase.valueresulthandler<map<string, object>>() {                 @override                 public void onsuccess(map<string, object> result) {                     system.out.println("successfully created user account uid: " + result.get("uid"));                 }                 @override                 public void onerror(firebaseerror firebaseerror) {                     // there error                 }             });              firebase set_user = userdata.push();             string user_id = set_user.getkey();             //save database failed             map<string, object> save_user = new hashmap<string, object>();             save_user.put("disp_name", dispname.gettext().tostring());             save_user.put("real_name", rl_name.gettext().tostring());             save_user.put("email_addr", emailaddr.gettext().tostring());             save_user.put("user_pwd", passwd.gettext().tostring());             save_user.put("id",user_id);             set_user.setvalue(save_user);

enter image description here

the following errors running code above.

vfy: unable find class referenced in signature (lorg/shaded/apache/log4j/logger;)

and

vfy: unable resolve static field 9561 (warn) in lorg/shaded/apache/log4j/priority;

these warnings shaded version of apache httpclient library firebase includes , affect logging disabled default. caused reflection not working shading. should not prevent firebase library working , can ignore these warnings now.

c++ - Delete matches in OpenCV (Keypoints and descriptors) -

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
