    <p>I'm trying to connect to a FTP using Apaches FTPSClient but I keep getting this error:</p> <p>06-15 09:15:14.749: W/System.err(29451): java.io.IOException: Could not initialize SSL context</p> <p>This happens with the following code, the error comes on the second line (connect).</p> <pre><code>ftpsClient = new FTPSClient("SSL"); ftpsClient.connect(host); int reply = ftpsClient.getReplyCode(); if(!FTPReply.isPositiveCompletion(reply)) { ftpsClient.disconnect(); } ftpsClient.login(user, password + nl); ftpsClient.setFileType(FTP.BINARY_FILE_TYPE); ftpsClient.enterLocalPassiveMode(); </code></pre> <p>Any suggestions of what I might be doing wrong?</p> <p>EDIT:</p> <p>full stacktrace</p> <pre><code>06-15 09:15:14.749: W/System.err(29451):

    2. COFor some reason it's not finding a valid KeyManager. On what device/Android version are you running this? Also try `new FTPSClient("TLS");` to see if it makes a difference.

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.
