How to get the number of unread gmail mails (on android)

by

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 protected]";
    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());
    }
}

Requires permission

<uses-permission android:name="com.google.android.gm.permission.READ_GMAIL"/>
