this game similar 1 of try survive long possible, hell-shooter games. so wish record amount of time user can survive after pressing "start". similarly, continue update frames @ time. thinking using handler or timer or animation updating frames (the activity) , mathematically manipulating simpledateformat. however, i'm not sure how 1 go it. as start, have of fruitninja survival mode, though smaller times recorded too. thanks! you can use timer or thread handler timer = new timer(); timer.schedule(new timertask() { @override public void run() { own code ///////schedule timer, after first 100ms timertask run every 1000ms } }, 1000, 1000); can use handler handler handler = new handler(); handler.postdelayed( new runnable() { public void run() { afficher(); } }, 1000l);

i trying add library project because want change in class there. why adding dependencies in gradile setting not enough. i know in library says "if want use library, have download materialdesign project, import workspace , add project library in android project settings.". mean, should copy files , put them in libs folder ? quoting the documentation : if want use library, have download materialdesign project, import workspace , add project library in android project settings. step #1: download project, whether via zip file github gives or using git clone repository step #2: move materialdesign/ directory project directory, peer of existing app/ module step #3: modify settings.gradle in project directory include :materialdesign in list of modules build step #4: in app module's build.gradle file, add compile project(':materialdesign') dependencies
