MTK Android P 开机无动画，无铃声问题和开机铃声不同步，首次开机无铃声的问题

最近做Android9.0的项目定制出现开机动画铃声的问题，以下是解决方案

解决预置开机动画，铃声无效果的问题

1.device/mediatek/mt6739/device.mk

PRODUCT_PACKAGES += mtkbootanimation
PRODUCT_PACKAGES += libmtkbootanimation

2.device/mediatek/sepolicy/basic/non_plat/audioserver.te

allow audioserver bootanim:binder call;

3.frameworks/base/cmds/bootanimation/
在改文件夹下面将Android.mk文件修改为Android_disable.mk(当然删掉也是一样的)

4.vendor/mediatek/proprietary/operator/frameworks/bootanimation/
在改文件夹下面将Android_disable.mk文件修改为Android.mk

5.vendor/mediatek/proprietary/operator/frameworks/bootanimation/MtkBootanimation/
在改文件夹下面将Android_disable.mk文件修改为Android.mk

6.vendor/mediatek/proprietary/frameworks/base/services/core/java/com/mediatek/server/MtkShutdownThread.java

private boolean showShutdownAnimation(Context context) {
.................
             bootanimCust(context);
             return true;
         }
-        return false;
+        return true;
     }
 
     private static void bootanimCust(Context context) {
  ........

 public static int isCustBootAnim() {
 .........................
                 sysProp = "NONE";
                 mode = DEFAULT_MODE;
             }
+            mode = ANIMATION_MODE; //Enable Shutdown Animation
             mShutOffAnimation = mode;
             Log.i(TAG,"mShutOffAnimation: " + mode + " (" + sysProp + ")");
             return mode;
 }

7.vendor/mediatek/proprietary/operator/frameworks/bootanimation/MtkBootanimation/BootAnimation.cpp

bool BootAnimation::threadLoop()
{
.......
     // We have no bootanimation file, so we use the stock android logo
     // animation.
     sp<MediaPlayer> mediaplayer;
-    const char* resourcePath = NULL;
+    const char* resourcePath = initAudioPath();
     status_t mediastatus = NO_ERROR;
     if (resourcePath != NULL) {
         bPlayMP3 = true;
.......
}

解决完开机动画显示发现首次开机还是无铃声，而且铃声和动画并不同步

解决铃声不同步问题

1.frameworks/av/media/libstagefright/MediaCodec.cpp

void MediaCodec::setState(State newState) {
...........
     cancelPendingDequeueOperations();
 
-    updateBatteryStat();
+    //updateBatteryStat();
 }
 
 void MediaCodec::returnBuffersToCodec(bool isReclaim) {

2.frameworks/av/services/audioflinger/AudioFlinger.cpp

       mClientSharedHeapSize(kMinimumClientSharedHeapSizeBytes),
       mGlobalEffectEnableTime(0),
-      mSystemReady(false)
+      mSystemReady(true)
 {
     // unsigned instead of audio_unique_id_use_t, because ++ operator is unavailable for enum
     for (unsigned use = AUDIO_UNIQUE_ID_USE_UNSPECIFIED; use < AUDIO_UNIQUE_ID_USE_MAX; use++) {

3.vendor/mediatek/proprietary/operator/frameworks/bootanimation/MtkBootanimation/BootAnimation.cpp

 bool BootAnimation::threadLoop()
 {
 .........
     if (bPlayMP3 && mediastatus == NO_ERROR) {
         AutoMutex _l(mMyLock);
         if (!bAudioStarted) {
-            status_t err = mCondition.waitRelative(mMyLock, s2ns(4));
+            status_t err = mCondition.waitRelative(mMyLock, s2ns(40));
             ALOGD("audio started re %d", err);
         }
     }
 .......
 }
