        </intent-filter>
    </activity>

    <activity android:name="com.example.careandcure.MapsViewActivity" >
    </activity>
    <activity

        <meta-data
            android:name="android.app.searchable"
            android:resource="@layout/searchable" />
    </activity>
    <!-- declare the default searchable Activity for the whole app -->
    <meta-data
        android:name="android.app.default_searchable"
        android:value=".MySearchAbleActivity" />
 </application>

 </manifest>

和得到以下错误：

推荐答案

您的元数据标签是在＆LT内部;活动> 标记。取出，并把它应用标签之后：

Your metadata tag is inside the < activity> tag. Remove and place it right after the application tag:

<application
android:allowBackup="true"
android:icon="@drawable/logo"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
    <meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />
    <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="AIzaSyBOhdOOMI_ZMYlvSyi7DVeRe_bo9ckxehM" />
    <meta-data
        android:name="android.app.searchable"
        android:resource="@layout/searchable" />
<activity>//not activity tags
