解决方案:  

       <provider ....  />   习惯性的使用这种方式结束 provider,  导致 <meta-data 没有被包含到 provider中,(细节问题)

报错前:

<provider
    android:authorities="com.gdvictor.ivhelmet.fileprovider"
    android:name="android.support.v4.content.FileProvider"
    android:exported="false"
    android:grantUriPermissions="true"/>
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/file_paths" />

解决后:

<provider
    android:authorities="com.gdvictor.ivhelmet.fileprovider"
    android:name="android.support.v4.content.FileProvider"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/file_paths" />
</provider>
