问题代码片段：



$r5 = (cn.com.opda.android.sevenkey.WidgetConfig) $r4,<cn.com.opda.android.sevenkey.SevenKeyWidget: void a(android.content.Context,android.content.Intent)>



问题java代码

private void a(Context arg8, Intent arg9) {        int i3;        int i = 3;        int i1 = 2;        int i2 = -1;        String string = arg9.getAction();        if(string != null) {            if(string.equals("com.dianxinos.optimizer.action.SW_TOGGLE")) {                Parcelable parcelable = arg9.getParcelableExtra("widget_config");                i = arg9.getIntExtra("switch_id", i2);                Object object = SevenKeyWidget.a.get(i);                Rect rect = arg9.getSourceBounds();                if(object == null) {                    return;                }                else if(parcelable != null) {                    SevenKeyWidget.a(arg8, ((kf)object), ((WidgetConfig)parcelable), i, rect);//crash
