Android: Cursor Window is full

问题

W/CursorWindow(15677): Window is full: requested allocation 2195889 bytes, free space 2096720 bytes, window size 2097152 bytes

I know there is app memory avaliable:

D/dalvikvm(15677): GC_FOR_ALLOC freed 9K, 30% free 17050K/24291K, paused 45ms

So its purely to do with the cursor size window, when Reading blob into byte[].

Im using the built in method to read blobs from a cursor.

    try
    {
        c = rdb.query("Photos", new String[]{"photo"}, "id = ?", new String[]{""+photoID}, null, null, null);
        if(c.moveToFirst())
        {
            byte[] tArray = c.getBlob(c.getColumnIndex("photo")); // THIS LINE ERRORS
        }               
    }catch(Exception e)
    {
        e.printStackTrace();
    }
    c.close();

    return tArray;

Is there a way around this? The window size seems to be limited to 2097152 bytes.

回答1:

It seems that the best way around this is to store the Photo on the SDCard, and save the URI in the DB.

While I wanted to avoid this, it's not too bad, and is much more stable.
