if (mCopyMap != null) {
        List<Integer> list = this.a(mCopyMap);
        if (list != null) {
            if (isBackupPlay) {
                if (list.size() > 1) {
                    this.a((Integer)list.get(1));
                }
            } else {
                this.a((Integer)list.get(0));
            }
        }
    }
}

能否改为如下： if(list.size() > 0){ this.a((Integer)list.get(0)); }
