OOM bitmap size exceeds VM budget 处理

我在从widget 多次进入程序，再退出到桌面，再通过widget进入程序，反复操作，出现如下异常
 启动activity的代码 
 MailListBindData mailData = ServiceForWidget.getWidgetData()
                        .get(curPosition);
                Intent showEmailDetail = new Intent();
                showEmailDetail.setClass(context,
                        MailDetailAndDoneActivity.class);
                showEmailDetail.putExtra(MailListActivity.extraKey_ThreadMode,
                        false);
                showEmailDetail.putExtra(MailListActivity.extraKey_accountId,
                        mailData.getMessageInfo().getAccountId());
                showEmailDetail.putExtra(MailListActivity.extraKey_folderId,
                        mailData.getMessageInfo().getFolderId());                showEmailDetail.putExtra(
                        MailListActivity.extraKey_groupPosition, curPosition);
                showEmailDetail.putExtra(
                        MailListActivity.extraKey_childPosition, 0);
                showEmailDetail.putExtra(MailListActivity.extraKey_editType,
                        MailListActivity.EDITTYPE_NONE);
                showEmailDetail.putExtra(MailListActivity.extraKey_objectView,
                        Constants.MAIL_DETAIL_VIEW);                showEmailDetail.putExtra("messageInfo",
                        mailData.getMessageInfo());                showEmailDetail.putExtra(MailListActivity.extraKey_MailCount,
                        ServiceForWidget.getWidgetData().size());
                showEmailDetail.putExtra(Constants.ACTIVITY_NAME_KEY,
                        MediumMailWidget.class.getSimpleName());
                showEmailDetail
                        .putExtra(
                                MailListActivity.extraKey_MailTypeTitle,
                                context.getString(R.string.unified_account_receive_folder_name));
                showEmailDetail.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                showEmailDetail.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);                context.startActivity(showEmailDetail);
