android的一个坑

Unable to resume activity : android.database.StaleDataException: Attempted to access a cursor after it has been closed. 异常

 

ContentResolver cr = this.getContentResolver();
Cursor actualimagecursor= cr.query(uri, proj,null, null, null);

// @SuppressWarnings("deprecation")  --会导致错误
// Cursor actualimagecursor = this.managedQuery(uri, proj, null, null,
// null);
