Android: Marking text message (SMS) unread

Question

For some reason, NO sms app on android seem to offer the very basic feature (that even old dumb-phones have) of marking an SMS unread.

I am considerinng writing such an app myself, but before I begin I would like to know a little bit about how to do it and why it hasn't been done before. Surely it is not impossible?

Answer 1

NOTE: Firstly, just to let you know in Android it is little typical to work with Messaging System in Android(2.3 or lower) as to work with things like SMS requires to query with Content Providers which is officially not available and also Android guys have warned about it. You can check about it in the below URL: http://android-developers.blogspot.in/2010/05/be-careful-with-content-providers.html

Further for your solution and just for everybody's concern would like to divide my explanation according to Android OS versions:

- Version 2.3 or lower: Yes application is as simple to make as guided by Pankaj Kumar and it will work for the above mentioned Android OS version and lower.

- Version 4.0 & up: Application will fail and not work. Yes, as warned by Android Dev Guys, from this version and up, you will not be able to read Messaging contents as I have tried it so your application will not work on coming Android releases. You can only get the numbers of them like: inbox, sent, outbox failed etc... but you cannot modify or read contents.

- Version > 3.0 & < 4.0 : Never tested and tried.

Hope this information helps you and saves your time for going on a dead end route :)))

Below snippet marks all SMS as Unread you can chnage it to match the id and only make unread that SMS

package org.vipul;

import android.app.Activity;
import android.content.ContentValues;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;

public class SMSSampleActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Uri uri = Uri.parse("content://sms/inbox");
        Cursor cursor = managedQuery(uri, null, null, null, null);

        for (int i = 0; i < cursor.getColumnCount(); i++) {
            Log.i("vipul", cursor.getColumnName(i));
        }

        if (cursor.moveToFirst()) {
            do {

                String id = cursor.getString(0);

                ContentValues contentValues = new ContentValues();
                contentValues.put("read", false);
                getContentResolver().update(uri, contentValues, "_id=?",
                        new String[] { id });
                contentValues.clear();
            } while (cursor.moveToNext());

        }
    }
}

Finally add android.permission.READ_SMS ans android.permission.WRITE_SMS in manifest
