What is the package of your BroadcastReceiver class which is Main.java?

<receiver android:name=".Main" >
    <intent-filter>
        <action android:name="android.content.Intent.ACTION_BATTERY_CHANGED" />
    </intent-filter>
</receiver>

It should not com.cy.headset right? Since it will be a conflict with your main activity which is Main.java

I think there are two solutions on this one specify the package of your receiver in the manifest.

example:

<receiver android:name="com.package.name.Main" >
    <intent-filter>
        <action android:name="android.content.Intent.ACTION_BATTERY_CHANGED" />
    </intent-filter>
</receiver>

Or if you want your receiver to be at the same package of your main activity which is Main.java rename your receiver

example:

<receiver android:name=".BatteryChange" >
    <intent-filter>
        <action android:name="android.content.Intent.ACTION_BATTERY_CHANGED" />
    </intent-filter>
</receiver>

<activity
    android:name="com.cy.headset.Main"
    android:label="@string/app_name" >
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />

        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

Another way to do it is.

<receiver android:name="com.cy.headset.BatteryChange" >
    <intent-filter>
        <action android:name="android.content.Intent.ACTION_BATTERY_CHANGED" />
    </intent-filter>
</receiver>

<activity
    android:name="com.cy.headset.Main"
    android:label="@string/app_name" >
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />

        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>
