android - Why do defaultsharedpreferences get but saved when I exit my app? -


i have simple activity consisting of main activity, second activity , preferenceactivity.

what do:

  1. i run app, mainactivity triggers oncreate
  2. oncreate fetches sharedpreferences , prints value console
  3. i go settings, change value of amount , press back.
  4. oncreate triggers again , logs newly set value (good)
  5. the oncreate triggers repeating alarm. in receiver class log sharedpreferences.
  6. the problem: value logged in receiving class still old value!
  7. next close app. alarm keeps running (as should) , receiver starts logging new, correct value.

so, change preference value picked in main activity other classes requires app exit / restart pickup change.

i've been reading google documentation preferences, followed tutorials, ... been struggling 3 evenings.

advice appreciated.

edit: found problem, had in manifest

<receiver android:name="alarm" android:process=":remote" />

because on process preference changes not detected

opencv - DataType<cv::detail::deriv_type>::depth what is it used for -

i wondering why line used in lucas kanade tracker in opencv: datatype<cv::detail::deriv_type>::depth can explain me? in opencv, depth of mat refers type of data contained in mat 's data buffer. represented integer values correspond given data type. these integers commonly abstracted appropriate macro definition (e.g. uchar data represented macro cv_8u ). cv::datatype type-traits class provides method obtain corresponding integer value without having memorize macro means data type. there few cases user code needs use datatype::depth . more common datatype::type . a simple example shows 1 possible use of datatype::depth : cv::mat uchar_data = cv::mat::ones(3, 3, cv_8uc1); cv::mat float_data; uchar_data.convertto(float_data, cv::datatype<float>::depth); // ^^ equivalently replaced // cv_32f macro float_data.at<float>(0,1) += 0.5f; std::cout << float_data << std::endl;...

python 3.x - Mapping specific letters onto a list of words -

can please suggest approach write piece of codes automatically maps letter in letter_str onto dic_key (a dict key string type contains dashes match length of words in word_lst)? so, mapping occurs if letter appears in every words in list @ same position no matter how many words in list. if no letter appears @ position words in word list new_dic_key '----'. please see examples below thanks word_lst = ['ague', 'bute', 'byre', 'came', 'case', 'doze'] dic_key = '----' letters_str ='abcdefghijklmnopqrstuvwxyz' new_dic_key = '---e' if word_list = ['bute', 'byre'] new_dic_key = 'b--e' or word_list = ['drek', 'drew', 'dyes'] new_dic_key = 'd-e-' if words in word_list of same length code give want: word_list = ['drek', 'drew', 'dyes'] cols = [] in range(len(word_list[0])): cols.append([]) word in ...
