闪屏分析

闪屏和不闪屏的区别

闪屏有两个 animation

而不闪屏的只有一个(设置同时设置lock screen和home screen的background image)

不闪屏的:

    Slog.v(TAG, "WP target app xform: " + appTransformation);
} else {
    android.util.Log.w("jackywei","this = "+this.hashCode()+",WP target app xform: = null");
}

WP target app xform 和这个wpAppAnimator变量有关系

可以Fix的代码

void computeShownFrameLocked() {
    final boolean selfTransformation = mHasLocalTransformation;
    Transformation attachedTransformation =
            (mParentWinAnimator != null && mParentWinAnimator.mHasLocalTransformation)
            ? mParentWinAnimator.mTransformation : null;
    Transformation appTransformation = (mAppAnimator != null && mAppAnimator.hasTransformation)
            ? mAppAnimator.transformation : null;
    appTransformation = null; //jackywei is can fix the bug.这个代码可以解BUG,但是,不知道会引起其他什么问题.
    // Wallpapers are animated based on the "real" window they
    // are currently targeting.
    final WindowState wallpaperTarget = mWallpaperControllerLocked.getWallpaperTarget();
    android.util.Log.w("jackywei","this = "+this.hashCode()+",wallpaperTarget= "+wallpaperTarget+",mIsWallpaper = "+mIsWallpaper);
    android.util.Log.w("jackywei","this = "+this.hashCode()+",mService.mAnimateWallpaperWithTarget= "+mService.mAnimateWallpaperWithTarget);
            wpAppAnimator.hasTransformation = false;//jackywei is can fix the bug.we must check where is the hasTransformation value from.这个代码可以解BUG,但是,不知道会引起其他什么问题.
            if (wpAppAnimator != null && wpAppAnimator.hasTransformation
                && wpAppAnimator.animation != null
                && !wpAppAnimator.animation.getDetachWallpaper()) {
            appTransformation = wpAppAnimator.transformation;//jackywei
            if (DEBUG_WALLPAPER && appTransformation != null) {
                Slog.v(TAG, "WP target app xform: " + appTransformation);
            } else {
                android.util.Log.w("jackywei","this = "+this.hashCode()+",WP target app xform: = null");
            }
        }
    }
