问题 I have been trying to get the backup of my sharedpreferences file in my Android app working and so far it is not. I am using the simple Google code from the developer's guide. Below is the code for the MyPrefsBackup class. public class MyPrefsBackup extends BackupAgentHelper { // The name of the SharedPreferences file static final String PREFS = "UserDB"; // A key to uniquely identify the set of backup data static final String PREFS_BACKUP_KEY = "prefs"; // Allocate a helper and add it to the

问题 I have implemented a BackupAgent following the guidelines for Data Backup. The code behaves as expected until StrictMode.VmPolicy is set to detect leaked closeable objects. After a backup is performed and GC occurs, CloseGuard reports a leaked ParcelFileDescriptor with this stack trace: 06-28 21:47:39.683 25072-25081/com.qbix.nub E/StrictMode﹕ A resource was acquired at attached stack trace but never released. See java.io.Closeable for information on avoiding resource leaks. java.lang

问题 I am using the BackupManager to backup SharedPreferences to the cloud. Now this works as expected when I use it on a single device and only perform a reinstall not a full uninstall. To do that I am clearing data which wipes prefs and than reinstalling the app from eclipse. If I first uninstall the app and after reinstall it the restore call reports no data to restore.
