ButterKnife error: cannot find symbol method bind(MyActivity)

Question

I recently switched to ButterKnife version 7.0.1 and I keep getting this error. It points to this part of the code:

Here's the exact part of the code:

public class SupportedBanksActivity extends AppCompatActivity {


 @Bind(R.id.activity_supported_banks_lv)
    ListView mListView;

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_supported_banks);
        ButterKnife.bind(this);
    }
}

and the error:

error: cannot find symbol method bind(SupportedBanksActivity)

I don't understand why it says that. I can go into this method of the ButterKnife library and I see that's it's there. I have made the following changes to my code:

build.gradle

lintOptions {
  disable 'InvalidPackage'
}

packagingOptions {
  exclude 'META-INF/services/javax.annotation.processing.Processor'
}

dependencies {
    compile 'com.jakewharton:butterknife:7.0.1'
}

proguard-rules.txt

-keep class butterknife.** { *; }
-dontwarn butterknife.internal.**
-keep class **$$ViewBinder { *; }

-keepclasseswithmembernames class * {
    @butterknife.* <fields>;
}

-keepclasseswithmembernames class * {
    @butterknife.* <methods>;
}

@Coeus Yep, multiple times. It seems to me though that the problem lies in ButterKnife somehow not recognizing my Activity as an Activity. It says 'cannot find symbol method bind(SupportedBanksActivity )' so as far as I understand it thinks that SupportedBanksActivity does not extend Activity — nsmirosh, Nov 25 '15 at 22:36
@nsmirosh Mmmm then try to extends your activity from AppCompatActivity — LordCommanDev, Nov 25 '15 at 22:38
You do not have any field with bind annotated - this might be the problem — ligi, Nov 25 '15 at 22:47
@ligi Sorry, didn't post the full code. There are actually annotated methods with '@Bind' — nsmirosh, Nov 25 '15 at 22:53
@nsmirosh what is shown when you auto-complete in AS after ButterKnife ? — ligi, Nov 25 '15 at 23:02
If there is no problem its just a suggestion try removing AppCOmpatActivity and just add Activity in it — Hardy, Nov 26 '15 at 04:44
