i want insert records table multiple number of times, have choice either use compilestatement or use db.insert shown below. string tablename = "table"; //fields in table: id, name sqlitestatement statement = db.compilestatement("insert "+tablename+" values(?,?);"); statement.bindlong(1,666); statement.bindstring(2,"john"); statement.executeinsert(); or string tablename = "table"; contentvalues values = new contentvalues(); values.put("id", 666); values.put("name", "john"); db.insert(tablename, null, values); which 1 should optimal? edit:- application running single threaded. insert() compiles sql on each invocation while compilestatement() approach compiles sql once. when same sql different bind arguments used more once, compilestatement() approach less work , faster. in addition, consider wrapping inserts in transaction reduce time spent waiting on i/o.

we have developed ios app makes use of push notifications. our client wants distribute app through own mdm server. means they'll compile , sign app , have appropriate apns certificate, include in our server-side application. far, good. now, client wants distribute app other devices aren't connected mdm server. mean different (adhoc, app store, ...) distribution channel different certificate chain. how should handle on our server side send push notifications apns? can send every push notification twice, once each certificate? need determine app installation requires device (depending on distribution channel)? this dependent on way distribute app. when distributing if application identifier same refer same app. if different install multiple times. means if have same app id in both cases enough send 1 notification no matter how distribute send notification. in case if have changed app ids yes have send multiple times. thing may change app id , introduce wildca...

i writing program find prime numbers using ol' sieve of eratosthenes algorithm (although twist). in order halve size of byte-array needed, don't represent numbers, , stick odd (calculating position in array integer division two). i have 1 problem, however. program doesn't seem recognize 17 or 113 prime numbers, although indeed prime numbers. here code: public class eratosthes { byte[] checklist; int range; public eratosthesconcurrent(int range) { this.range = range/2; this.checklist = new byte[this.range]; this.initallchecked(); this.findprimesseq(); this.printprimes(); } private void initallchecked(){ for(int = 1; < checklist.length; i++){ checklist[i] = 1; } } private void crossout(int i){ checklist[i/2] = 0; } private void findprimesseq(){ int curr = 3; outer: while(curr < range*2){ for(int = curr*curr; < range*...

im fixing bugs when app not main active app. devices pause message, lost messages etc. these expect. thing dont on moto g device destroy message when returning app menus etc, or device put sleep. is there reason this? fixing up, seems harsh have destroy app because phone call or sleep device, not im loading complex game or anything the moto g appears have rather aggressive memory management. android has low memory killer, determines processes kill depending on device configurations. while moto g have 1gb of ram, minfree settings applied motorola seem kill apps on background. there instructions on web how address user, developer, best save state when backgrounded in onpause(). http://m.androidcentral.com/fine-tuning-minfree-settings-improving-androids-multi-tasking http://developer.android.com/reference/android/app/activity.html#processlifecycle

i new jasmine testing , not solid picture how unittest controller. controller assignments , want test following: mock service calls. mock data in scope. test behaviour of particular method in controller. verify that: service has been invoked once. verify that: service passed correct data. i need have complete possible example how write test, , declarations use mock methods. controller method in question looks this: .controller('projectconfigurationctrl', function($scope, $routeparams, infraservice, projectconfigurationservice) { // pre-init... $scope.clickupdate = function() { if ($scope.projectdata.id === 0) { projectconfigurationservice.save(angular.tojson($scope.projectdata), function(project) { $scope.projectdata = project; $scope.newproject = false; $scope.info = "project " + project.projectname + " created successfully."; }, function() { $scope.info = "project " + $scope.proje...
