Package Restructure

Chat SDK V6 brings some package changes that need to be addressed in order to successfully complete the transition from v5 to v6.

Android Manifest

First of all, let's look at the AndroidManifest.xml changes. The following changes are required to be made in the AndroidManifest.xml file in case you've used the Stream's classes directly in your manifest:

Was: io.getstream.chat.android.ui.common.ChatUIInitializer
Now: io.getstream.chat.android.ui.initializer.ChatUIInitializer

Was: io.getstream.chat.android.ui.gallery.AttachmentGalleryActivity
Now: io.getstream.chat.android.ui.feature.gallery.AttachmentGalleryActivity

Was: io.getstream.chat.android.ui.gallery.AttachmentMediaActivity
Now: io.getstream.chat.android.ui.feature.gallery.AttachmentMediaActivity

Was: io.getstream.chat.android.ui.gallery.AttachmentActivity
Now: io.getstream.chat.android.ui.feature.gallery.AttachmentActivity

Was: io.getstream.chat.android.ui.channel.ChannelListActivity
Now: io.getstream.chat.android.ui.feature.channels.ChannelListActivity

Was: io.getstream.chat.android.ui.message.MessageListActivity
Now: io.getstream.chat.android.ui.feature.messages.MessageListActivity

// UI Common
Was: com.getstream.sdk.chat.view.activity.AttachmentDocumentActivity
Now: io.getstream.chat.android.ui.common.feature.documents.AttachmentDocumentActivity

View Components

Second of all, any XML layouts that were using the Stream's classes directly should be updated to use the new package names along with imports in a codebase.

note

If you forget to update the XML layouts, you may get an error at compile time, something like this:

Type mismatch: inferred type is ChannelListView but 
io.getstream.chat.android.ui.feature.channels.list.ChannelListView was expected

Alternatively it may crash at runtime with the error similar to this:

android.view.InflateException: Binary XML file line #58 
  in io.getstream.chat.ui.sample.debug:layout/fragment_channels:
    Binary XML file line #58 in io.getstream.chat.ui.sample.debug:layout/fragment_channels: 
      Error inflating class io.getstream.chat.android.ui.search.list.SearchResultListView

Here you can find elaborated examples of the changes that are required to be made:

Was: io.getstream.chat.android.ui.avatar.ChannelAvatarView

ChatUI customization

Thirdly, you may need to update imports of Stream's classes in case you've used them while customizing ChatUI:
