    <p>The problem is with <code>Database file</code> size. You can make a <code>Zip</code> of your <code>Database</code> file and then copy it to your local path from <code>Assets</code>.</p> <p>Here is the link: <a href="https://stackoverflow.com/questions/5945059/how-to-use-sqlite-connection-from-asset-folder/5950967#5950967">Copy Db File From Assets</a></p> <p>Now, in that code replace the <code>copyDataBase()</code> function with the below one.</p> <pre><code>private void copyDataBase() throws IOException { try { InputStream mInputStream = mContext.getAssets().open(DB_NAME_ZIP); String outFileName = DB_PATH + DB_NAME_ZIP; OutputStream mOutputStream = new FileOutputStream(outFileName); byte[] buffer = new byte[1024]; int length; while ((length = mInputStream.read(buffer)) &gt; 0) { mOutputStream.write(buffer, 0, length); } ZipFile mZipFile = new ZipFile(DB_PATH + DB_NAME_ZIP); InputStream nInputStream = mZipFile.getInputStream(mZipFile.getEntry(DB_NAME)); OutputStream nOutputStream = new FileOutputStream(DB_PATH + DB_NAME); while ((length = nInputStream.read(buffer)) &gt; 0) { nOutputStream.write(buffer, 0, length); } nOutputStream.flush(); nOutputStream.close(); nInputStream.close(); // Close the streams mOutputStream.flush(); mOutputStream.close(); mInputStream.close(); } catch (Exception e) { e.printStackTrace(); } finally { //Delete Zip file to minimize memory usage final String mPath = DB_PATH + DB_NAME_ZIP; final File file = new File(mPath); if (file.exists()) file.delete(); } } </code></pre> <ul> <li>Here <code>DB_NAME_ZIP</code> is the <code>Database Zip</code> file what you put in <code>Assets</code> folder like <code>Android.zip</code> but it actually contains <code>Android.sqlite</code> or <code>Android.db</code>.</li> </ul> <p>I hope this one can help you.</p>

    1. COI need the adapter class too? I didn't need it when I used the DataBaseHelper class from this link: http://www.reigndesign.com/blog/using-your-own-sqlite-database-in-android-applications/ It seems like a lot of extra work to use the adapter. Is it possible to use your method with the code I'm using?

    2. CO@rar Yes It is possible to use my method inside your code but please be careful as I separated all methods among two class `DatabaseHelper` and `DBAdpater`.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
