Here's some code snippet. Not sure it works and can't test it. But I hope it will help you to continue the investigation.
public static final class LabelColumns {
public static final String CANONICAL_NAME = "canonicalName";
public static final String NAME = "name";
public static final String NUM_CONVERSATIONS = "numConversations";
public static final String NUM_UNREAD_CONVERSATIONS = "numUnreadConversations";
}
public void queryLabels(){
String account="email@company.com";
Uri LABELS_URI = Uri.parse("content://gmail-ls/labels/");
Uri ACCOUNT_URI = Uri.withAppendedPath(LABELS_URI, account);
ContentResolver contentResolver=myActivity.getContentResolver();
Cursor cursor = contentResolver.query(ACCOUNT_URI, null, null, null, null);
//iterate over all labels in the account
if (cursor.moveToFirst()) {
int unreadColumn = cursor.getColumnIndex(LabelColumns.NUM_UNREAD_CONVERSATIONS);
int nameColumn = cursor.getColumnIndex(LabelColumns.NAME);
do {
String name = cursor.getString(nameColumn);
String unread = cursor.getString(unreadColumn);//here's the value you need
} while (cursor.moveToNext());
}
}
