POBackupManager & BackupAgent in Android 2.2
text
Body
copied!<p>I've reviewed the docs and the sample BackupRestore app and written my own test app implementing <code>android:backupAgent</code>. I extended the <code>BackupAgent</code> class because my main concern is being able to backup data from a database. I can't seem to even make a simple proof-of-concept app work with this feature.</p> <p>To make things exceptionally simple, I declared the <code>android:backupAgent</code> as <code>MyBackupAgent</code> in the manifest. I then created a class MyBackupAgent.java, extending <code>BackupAgent</code>. I then created overrides for the <code>onBackup()</code> and <code>onRestore()</code> methods within the <code>MyBackupAgent</code> class, just like in the examples and docs. I added a <code>Log.i()</code> call to the very beginning of each function so that I could identify within LogCat when the functions were being called. Likewise, I set breakpoints on both of these. I then went on to implement my code to backup the database.</p> <p>I created an emulator image using 2.2w/Google API's and even added a gmail account under Accounts & Sync. Running through the adb commands to enable <code>bmgr</code>, backup the app, run the backup, uninstall the app, reinstall the app etc.... I never once get a message in the log file from the <code>Log.i()</code> command in either of the <code>onBackup()</code> or <code>onRestore()</code> functions.</p> <p>I tried again on my Evo 4g running 2.2. Same result. It does not appear that the backup manager is calling the <code>onBackup()</code> and <code>onRestore()</code> functions in the <code>MyBackupAgent</code> class.</p> <p>The only odd message I get in my logs is one from the <code>BackupManagerService</code> stating "Backup pass but e=true p=false", I believe in response to the ADB command to backup the app.</p> <p>Any suggestions? Am I wrong to assume that a <code>Log.i()</code> statement in the <code>onBackup()</code> and <code>onRestore()</code> functions would show up in LogCat?</p>
