Security exception in binding service in android from an activity in separate app mentioning permission denial

Question

I have developed a bounded service app in android to get data from a Glucose meter device over USB serial port.I have developed another activity in a different app from where I am launching the service to get data in the activity screen.

I am getting following error when I am trying to install the activity app on my device

I have declared following permissions in manifest files of both my activity and service app.

This is the manifest file for my Service app

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

            android:resource="@xml/device_filter" />
    </service>
</application>

This is the manifest file for my Activity app

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.tcs.cto.omronglucoseui"

    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.tcs.cto.omronglucoseui.OmronGlucoseUIActivity"
        android:label="@string/app_name"
        android:permission="android.hardware.usb.host">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
          <intent-filter>
            <action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" />
        </intent-filter>
         <meta-data
            android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED"
            android:resource="@xml/device_filter" />
    </activity>
</application>

I have added

  android:permission="android.hardware.usb.host">

in both my apps.

When I am installing the service app first,it is getting installed But then I am trying to install the activity app,and it is throwing the error

     java.lang.SecurityException: Permission Denial: starting Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10000000 cmp=com.tcs.cto.omronglucoseui/.OmronGlucoseUIActivity } from null (pid=12170, uid=2000) requires android.hardware.usb.host

I am getting following error (in logcat) when I am trying to call

    bindService(intent,serviceconnection,Context.BIND_AUTO_CREATE)

from the activity

 java.lang.SecurityException: Not allowed to start service Intent { act=com.tcs.cto.omronglucoseservice.GlucoseService } without permission android.hardware.usb.host

I am not getting any solution from existing questions in this site.

Any answer to this question is appreciated.
