android4.2版定制的Launcher， 有几率出现应用整个绘制成花屏、黑屏或者字体绘制成方块等问题，出现花屏问题的时候出现以上LOG

解决办法：

当View 调用destroyLayer()的时候判断如果当前的硬件加速不可用的时候，调用mHardwareRenderer的safelyRun来删除mHardwareLayer的资源

修改View.java destroyLayer(boolean valid)方法

boolean destroyLayer(boolean valid) {        if (mHardwareLayer != null) {            AttachInfo info = mAttachInfo;            if (info != null && info.mHardwareRenderer != null &&                    info.mHardwareRenderer.isEnabled() &&                    (valid || info.mHardwareRenderer.validate())) {                info.mHardwareRenderer.cancelLayerUpdate(mHardwareLayer);                mHardwareLayer.destroy();                mHardwareLayer = null;                invalidate(true);                invalidateParentCaches();            }            else if(info != null && info.mHardwareRenderer != null)            {            info.mHardwareRenderer.safelyRun(new Runnable() {@Overridepublic void run() {// TODO Auto-generated method stubmHardwareLayer.destroy();mHardwareLayer = null;if (mDisplayList != null)  mDisplayList.reset();  invalidate(true);             invalidateParentCaches(); }});            }            return true;        }        return false;    }
