NS-free test-app

NS-free Test App Specifications: Overview 1) 2 page app with very simple UI navigation buttons and widgets 2) Native app 3) For android devices running android 4.0 and higher, with screen sizes ranging between 3" and 7" Page 1 4) UI ... Three buttons- 'Play', 'Stop', 'Next'; One count up Timer 00:00:00, hours:minutes:seconds) 4-1) When 'Play' is pressed, i) an audio file ([login to view URL]) starts looping; and ii) the timer starts counting up from 00:00:00) 4-2) When 'Stop' is pressed, the audio stops playing and the timer resets to zero (in the full app, the timer value will be saved to the device). 4-3) When 'Next' is pressed, the app loads Page 2. Pressing 'Next' does not stop the timer or audio play. 4-4) The [login to view URL] audio file is attached. 4-5) In the full app, the audio file and timer must be able to play for up to 12 hours. Therefore, the audio play must be stable after the screen goes to sleep. The Developer should have the experience to know whether to run the audio as a service, in the main thread, or through notifications etc. 4-6) The timer should be accurate but can drift by 5% to 10% from correct time. Page 2 5) UI ... Three numeric input fields (minutes), One count up timer 00:00:00, One 'Start', one 'Stop' button, and one 'Back' button. 5-1) InputField1 labelled 'time 1'. InputField2 labelled 'time 2', InputField3 labelled 'time 3'. Input fields have range from 0 to 99 minutes. Inputs are used to play audio files for different time lengths, after pressing 'Start'. 5-2) When 'Start' is pressed- 5-2-1) [login to view URL] plays in a loop for variable 'time 1', then 5-2-2) [login to view URL] loop plays for variable 'time 2', then 5-2-3) [login to view URL] plays for 'time 3' minus 'time 2', then 5-2-4) steps 5-2-2 and 5-2-3 repeat a further 3 times. 5-3) As an example, if 'time 1' = 10 minutes, 'time 2' = 5 minutes, and 'time 3' = 20 minutes ... then when start is pressed, the audio files play as follows ... ship for 10 min, birds for 5 min, filler for 15 min, birds for 5 min, filler for 15 min, birds for 5 min, filler for 15 min, birds for 5 min, filler for 15 min, then timer and audio play stops. No need to provide code that checks for incorrect numeric field input (e.g. 'time 3' less than 'time 2'). 5-4) When 'Back' is pressed, the app changes to Page 1, but the timer and audio play continues on Page 2. 5-5) Coding to handle anomalous button presses are not needed in the test app. That is, I will not press start or stop etc on one page while another page is running a function. 5-6) The timer can drift by 5% to 10% from accurate time, but it is essential that for audio play times and order of play are correct. That is, the code to play looping files for the correct time and in the correct order, must execute sequentially. If the code is buffered it can be deleted or executed out of order, messing up the audio play functions. 5-7) The [login to view URL] and [login to view URL] audio files are attached.
