How to Check Unread Message in Android

You can check the number of unread SMS in android  in Android. You should use "content://sms/inbox".


Example Code:

public void SmsControl(){
             Uri sms_content = Uri.parse("content://sms/inbox");
             String where = "read = 0";
             Cursor c = context.getContentResolver().query(sms_content, null,where, null, null);
             c.moveToFirst();
             int Value = c.getCount();
             c.deactivate();
       }

I hope this code helps you. You can use "content://sms" or "content://sms/sent" for your needs.   
If you use "null" instead of "where" for every messages in phone.

When phone enters standby mode, activity which was recently active frozen and restored whenever needed. While this frozen time, activity doesn’t run. Because of that it doesn’t need sensor updates. And Android stop to listen some sensors for power management.

Services have this condition like classes (activity). In contrast to class, a service run every time, even when phone is in standby mode. Therefore Services needs sensor updates for some situations. But android stop to listen some sensor(accelerometer) in some different phones.

There is a solution for that. This is not an exact solution but it work with a lot of phones.

With a BroadcastReceiver listenIntent.ACTION_SCREEN_OFFand register sensor listener a…
