android - Add / Remove App Drawer Shortcuts -

-
i trying programmatically add , remove application shortcuts app drawer. understand app drawer knows applications should presented using intent filter launcher category. i able add/remove shortcuts specific activities in application, according dynamic conditions, why can't have them in manifest file. thank you. as far know, not possible. unfortunately, current android api level there no way add intentfilter s activity objects through code. check out this doc on intent filters. relevant quote: an intent filter instance of intentfilter class. however, since android system must know capabilities of component before can launch component, intent filters not set in java code, in application's manifest file (androidmanifest.xml) elements. (the 1 exception filters broadcast receivers registered dynamically calling context.registerreceiver(); directly created intentfilter objects.)

android - Refactor > Move overlaps the location of another project -

-
i trying move android project difference directory in workspace, using refactor > move. the problem "move project" dialog box keeps ok button disabled, while issuing following message in red: \winshare\sandbox\workspace\newdirname overlaps location of project: newdirname the funny thing is... directory named newdirname doesn't exist! (i later tried creating such directory outside of eclipse didn't help) any idea why is? i using eclipse 3.6.1 64-bit latest android sdk 9 (under windows 7). delete project. not delete resources filesystem. you can rename project folder outside of eclipse (using command line or file manager gui) now import project workspace (file -> import -> existing project workspace. the error message you're getting misleading. refactoring operations not intended projects. problem plugin should remove refactor options when selected item project rather package or class.

ruby - How to return an object from two tables form a rails web serivce? -

i have 2 activerecord models: event , place. event has property name place_id points place. place has column named place_name. how write web service returns json of events each event holds associated place_name value. i tried adding attr_accessor field name place_name event model , populate manually after selecting events. when do: render :json => events_collection_result the place_name doesn't appear in json. all of logic falls under activerecord associations . it's fundamental piece of rails functionality, it's documented. guide should more suffice. you'll want invoke belongs_to :place if event class definition. there, can access event's place name via @event.place.place_name , although i'd recommend rename place_name name . json won't display association default. there plenty of ways remedy this, basic of overwrite event#to_json , method called default when rails attempts produce json representation of activerecord instance.

c# - FFT on WP7 shows two mirrors -

-
hello i'm exploring audio possibilities of wp7 platform , first stumble i've had trying implement fft using cooley-tukey method. result of spectrogram shows 4 identical images in order: 1 normal, 1 reversed, 1 normal, 1 reversed. code taken c# project (for desktop), implementation , variables seem in place algorithm. can see 2 problems right away: reduced resolution , cpu wasted generate 4 identical spectrograms. given sample size of 1600 (could 2048) know have 512 usable frequency information leaves me 15hz resolution 8khz frequency span. not bad, not either. should give on code , use naudio? cannot seem have explanation why spectrum quadrupled, input data ok, algorithm seems ok. this sounds correct. have 2 mirrors, can assume 1 real part , other image part. standard fft. from real , image can compute magnitude or amplitude of each harmonic more common or compute angle or phase shift of each harmonic less common. gilad.

sql - Is it possible to JOIN on the NEW/OLD tables inside a trigger -

i want join incoming data (in new virtual table) other database tables inside instead of insert trigger. possible in sqlite? pseudo-ish code: create trigger vtablec_oninsert instead of insert on vtablec begin insert tablea (column1, column2) select new.column1, b.column2 tableb b join new n on b.vtablec_id = n.id end i tried, error: "no such table: main.new". i guess answer no, since according docs sqlite supports each row triggers, there's no virtual new table, array of fields each iteration.
