MediaPlayer and prepareAsync() method about sound with NativeAudioService for Android

Context: The play method of the NativeAudioService interface has been overloaded for a Real Time reason:

I have created one thread and one task by sound. The aim is to avoid disturbing the real time of the main cyclic thread, performed each 110 ms. These thread+task are performed where there is nothing else to do, in these 110 ms.
I have alse allowed to prepare sounds asynchronously

Consequence: for easily modifying the play() method, I have added two booleans: . bThreadTask for using one thread and its task, by sound OR not . bPrepareAsync for using asychronous sound OR not

The combination of these two booleans allow to test three interesting cases (the case "no thread" and "no asynchronysm" is the original configuration with Real Time problem).

Below, you can see these three results. Some explanation before reading them. And, sorry about some french words in the traces (even if I have translated some useful of them).

Time is in milliseconds

trace type n°1: "Beginning traitementCyclique": beginning of the cyclic processing that must be theorically done each 110 ms

trace type n°2: "End traitementCyclique - SUPER IMPORTANT - Execution time traitementCyclique : / tExec:" it is the real duration of this cyclic processing, provided at the end of it (INCLUDING the sound methods execution)

trace type n°3: "End traitementCyclique - Phase n°4 / tExec MAX in the phase" : it is execution duration of this cycle, WITHOUT taking into account the sound methods execution

trace type n°4: "AndroidNativeAudio - play xx: / noTask: yy / tExec:" audio trace of the play() method - See the code for the signification of numbers xx and yy

Analysis of results: SOLUTION1: with thread and without asynchronysm

1st case: all sounds are done at the end of the cycle (trace type n°4) and "push away" the reactivation of the next cycle ("tExec: 243") . The 110ms rate is not respected. . You can see that he duration of the processing without sounds is less than 110 ms ( "MAX in the phase : 95"). Sounds (with tasks from 43 to 45) disturb the Real Time See traces: "End traitementCyclique - SUPER IMPORTANT - Execution time traitementCyclique : / tExec: 243" and "I/System.out(28026): trace CPU - heure : 42400 ms --- tExec: End traitementCyclique - Phase no 4 / tExec MAX in the phase : 95"
2nd case: "AndroidNativeAudio - play 4a: / noTask: 57" related to mediaPlayer.start() is done at the end of the cycle BUT inside of it. That is correct. The next cycle begins at the right time.

Conclusion: when the user lightly practice the game (one touchScreen each second), the sound processing does not disturb the Real Time BUT, when he commonly practice it, sounds disturb it.

SOLUTION2: with thread and with asynchronysm Asynchronism systematically disturbs the cyclic task of 110 ms Tasks 36 and 37 disturb the real time because they are done inside during the cyclic processing

The rate is 200 ms (31451 - 31251)

SOLUTION3: without thread and with asynchronysm Same remark with task from 43 to 47

Note: You can also use this code in your own tests, if you want.
