T303 AIDLでプロセス間通信 データ送信（暗黙的intent:implicit）

暗黙的はimplicit

問題点は

サービス開始->データ送信
これはOK
で、サービス停止->データ送信
これも、動作してしまう・・

Manifest.xml

service にintent-filterを記述する

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.efolab.t303"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="17" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"

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

        </activity>

            </intent-filter>
        </service>
    </application>
