Butterknife library not working with HoloEverywhere/Android bootstrap

Question

I am currently coding on the Android Bootstrap app, I want to have the new DataPickers en make use of new widgets without worrying about porting back to 2.1+ so I use the HoloEveryWhere Library. I also use the Android Bootstrap with Butterknife library

When I debug I get this exception

E/AndroidRuntime﹕ FATAL EXCEPTION: main
    java.lang.RuntimeException: Unable to start activity ComponentInfo{nl.webridge.whtsnxt.debug/nl.webridge.whtsnxt.authenticator.BootstrapAuthenticatorActivity}: butterknife.ButterKnife$UnableToInjectException: Unable to inject views for nl.webridge.whtsnxt.authenticator.BootstrapAuthenticatorActivity@40619210

I think there's a problem with the HoloEverywhere activity I use in my app.

For example I use the import org.holoeverywhere.app.Activity; in all my Activity classes.

But the Butterknife use android.app.Activity; The problem is, I can't change code in the Butterknife to use the Activity from HoloEverywhere.

Please tell me your thoughts on this I use the latest version of Butterknife and HoloEveryWhere.

Answer 1

Try to set up in your AndroidManifest.xml the holo theme:

<application
     android:theme="@style/Holo.Theme.NoActionBar.Fullscreen"

or maybe only the in activity that is happening your problem (also in the manifest)

<activity
     android:theme="@style/Holo.Theme.NoActionBar.Fullscreen"

Of course in your java class, if the component is defined as a holo component in the xml layout, in your java class you have to import that component from the holo library like you are doing:

  import org.holoeverywhere.app.Activity

or

  import org.holoeverywhere. whatever  (like button, switch, whatever)

Answer 2

Check if your @InjectViews has correct type.

I've used ImageView instead of LinearLayout.

Answer 3

Also check if you are not using other ButterKnife's injection annotations incorrectly. I've used @OnItemClick annotation for RecyclerView, which was causing RuntimeException.
