How to implement multithreaded for both graphic animation and media player in bootanimation

[Faye Lynn]

Hi Droid-expert

 

For stock bootanimation in JB, there is a single threaded animation process/class inside. If I'd like to implement the power-on sound/tune as well. What's the best programming scheme/model it could be?

 

So far, by my understanding, I did something in BootAnimation.cpp in the following:

 

Did I do wrong? The handset boots up, it shows the animation first, and then the sound is played.

 

However, in a normal AOS adb shell session, try to run bootanimation, and it works fine (I mean both animation and sound are played at the same time)

 

Does the init is multi-threaded?

        mp->seekTo(0);

    sp<PlayerListener> player = new PlayerListener();

    player->run("BootAnimatedMelody", PRIORITY_AUDIO);

    if (mAndroidAnimation) {
        r = android();
    } else {
        r = movie();
