현재 content provider를 공부하고 있는데요.

서로다른 어플간의 DB를 공유하는 프로그램을 짜고 있는데.....

두개의 파일에 대해서 permission을 아래와 같이 주었습니다. 

==========================================================================

Mycontent 어플의  AndroidManifest.xml파일은

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    package="com.example.test"

    android:versionCode="1"

    android:versionName="1.0" >

    <uses-sdk

        android:minSdkVersion="8"

        android:targetSdkVersion="15" />

    <uses-permission android:name="com.example.mycontentprovider.permission.read"/>

    <uses-permission android:name="com.example.mycontentprovider.permission.write"/>

    <application

        android:icon="@drawable/ic_launcher"

        android:label="@string/app_name"

        android:theme="@style/AppTheme" >

        <activity

            android:name="com.example.test.MyContent"

            android:label="@string/title_activity_main" >

            <intent-filter>

                <action android:name="android.intent.action.MAIN" />

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

            </intent-filter>

        </activity>

    </application>

</manifest>

MycontentProvider 어플의 AndroidManifest.xml파일은 

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    package="com.example.mycontentprovider"

    android:versionCode="1"

    android:versionName="1.0" >

    <uses-sdk

        android:minSdkVersion="8"

        android:targetSdkVersion="15" />

    <permission android:name="com.example.mycontentprovider.permission.read"/>

    <permission android:name="com.example.mycontentprovider.permisson.write"/>

    <application

        android:icon="@drawable/ic_launcher"

        android:label="@string/app_name"

        android:theme="@style/AppTheme">

        <provider

            android:name=".MyContentProvider"

            android:authorities="com.example.mycontentprovider"

            android:readPermission="com.example.mycontentprovider.permission.read"

            android:writePermission="com.example.mycontentprovider.permisson.write">

        </provider>

    </application>

</manifest>
