    <p>I am trying to save a Bitmap List to a file. Basically, I want to store it for future reference so that when a user selects an image from gallery it stays there even when app closes.</p> <p>This is what I am trying to do? But getting a number of Exception- BufferUnderFlowException, OutOfMemoryException. The problem seems to be very large memory of Bitmap List. Is there any better way to do this?</p> <pre><code> final List&lt;Bitmap&gt; bitmapcontent=new ArrayList&lt;Bitmap&gt;(); ImageView imageView; Gallery gallery; private static byte[] bytesar; ByteBuffer dst; private void savethebitmap() throws IOException, ClassNotFoundException { try { FileOutputStream fos = openFileOutput("bitmapimage", Context.MODE_PRIVATE); ObjectOutputStream out=new ObjectOutputStream(fos); out.writeInt(bitmapcontent.size()); for(int i=0;i&lt;bitmapcontent.size();i++){ out.writeInt(bitmapcontent.get(i).getRowBytes()); out.writeInt(bitmapcontent.get(i).getHeight()); out.writeInt(bitmapcontent.get(i).getWidth()); int bmSize = bitmapcontent.get(i).getRowBytes() * bitmapcontent.get(i).getHeight(); if(dst==null || bmSize &gt; dst.capacity()) dst= ByteBuffer.allocate(bmSize); out.writeInt(dst.capacity()); dst.position(0); bitmapcontent.get(i).copyPixelsToBuffer(dst); if(bytesar==null || bmSize &gt; bytesar.length) bytesar=new byte[bmSize]; dst.position(0); dst.get(bytesar); out.write(bytesar, 0, bytesar.length); } } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } } private void loadthebitmap() throws IOException,ClassNotFoundException{ try { freeBitmaps(); FileInputStream fos = openFileInput("bitmapimage"); ObjectInputStream in=new ObjectInputStream(fos); int size=in.readInt(); for(int i=0;i&lt;size;i++){ int height=in.readInt(); int width=in.readInt(); int bmSize=in.readInt(); if(bytesar==null || bmSize &gt; bytesar.length) bytesar= new byte[bmSize]; int offset=0; while(in.available()&gt;0){ offset=offset + in.read(bytesar, offset, in.available()); } if(dst==null || bmSize &gt; dst.capacity()) dst= ByteBuffer.allocate(bmSize); dst.position(0); dst.put(bytesar); dst.position(0); Bitmap myVideoScreenshotBm=Bitmap.createBitmap(width, height, Bitmap.Config.RGB_565); myVideoScreenshotBm.copyPixelsFromBuffer(dst); bitmapcontent.add(myVideoScreenshotBm); } } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
