Welcome to StackOverflow!

Somewhere in your code, you are trying to allow users to upload files from their phone. The ImageView shouldn't be causing the problem, and the complete error message should say Missing android.support.FILE_PROVIDER_PATHS meta-data

And in order to make that go away, you need to add this in your AndroidManifest file

<meta-data
    android:name="android.support.FILE_PROVIDER_PATHS" 
    android:resource="@xml/provider_paths" />

Answer 2

have you miss the configration in your AndroidManifest.xml :

<provider
   android:name="android.support.v4.content.FileProvider"
   android:authorities="packagename.fileProvider"
   android:grantUriPermissions="true"
   android:exported="false">

   <meta-data
      android:name="android.support.FILE_PROVIDER_PATHS"
      android:resource="@xml/file_paths" />
</provider>
