 <receiver android:name="com.hanuman.sensor.receiver.SensorReceiver" >
            <intent-filter
                android:enabled="true"
                android:exported="false" >
                <action android:name="android.intent.action.USER_PRESENT" />
            </intent-filter>
        </receiver>

String action = intent.getAction();
        if (action.equals(Intent.ACTION_USER_PRESENT)) {
            System.out.println("User is present");
            Intent s = new Intent(context, MainActivity.class);
            s.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(s);
        } else {
            System.out.println("User is not present");
        }
