java.lang.RuntimeException: Unable to destroy activity {com.cntaiping.life.ehome/com.cntaiping.life.ehome.ui.greenlife.PostIssueActivity}: 

java.lang.NullPointerException: Attempt to invoke virtual method 'void android.graphics.Bitmap.recycle()' on a null object reference

问题发生代码处：

    protected void onDestroy() {
        super.onDestroy();
        for (Bitmap imageItem : thumbnails) {
            if(imageItem!=null){
            imageItem.recycle();
            imageItem=null;
            System.gc();
            }
        }

图片为空 加入了非空判断 if(imageItem!=null)
