在哪里存储标记的描述数据以避免外部存储错误？

我有1700个带有字符串的标记，其中包含地图上每个标记的描述。我收到内存不足错误，因为我为每个标记“点击更多信息”下一个屏幕活动持有这么多字符串。如何才能更好地保存这些数据并在标记点击时共享它而不会出现此内存问题？我从基于XML的文件中提取数据。

这是我崩溃后的错误日志：

我将它们发布在地图上，如下：

BitmapDescriptor icon = BitmapDescriptorFactory
                        .fromResource(R.drawable.snotel_marker);
                int nsize = visibleMarkers.size();
                for (int i = 0; i < nsize; i++) {
                    MapMarkers marks = new MapMarkers();
                    String title = visibleMarkers.valueAt(i).getTitle();
                    String desc = visibleMarkers.valueAt(i).getDesc();
                    Float latitude = visibleMarkers.valueAt(i).getLat();
                    Float longitude = visibleMarkers.valueAt(i).getLon();

                    m = map.addMarker(new MarkerOptions()
                            .position(new LatLng(latitude, longitude))
                            .title(title).icon(icon));

                    marks.setTitle(title);
                    marks.setDesc(desc);

                    m.setData(marks);

在信息窗口中单击下一个活动填充如下：

getSupportActionBar().setTitle(extras.getString("name"));
            webview.loadDataWithBaseURL(null, extras.getString("description"),
                    "text/html", "utf-8", null);

应用程序在我的GNex上正常运行，但在我的旧Droid上，它填充了地图，然后点击3或4个标记并移动地图后我得到了内存不足错误。我可以分享任何其他输出来试图解决这个问题吗？
