Butterknife: Null View

[hanhmh1203]

Hi friends,
I get problem.
In first time I call ButterKnife.bind(this); in onCreate activity, it ok.
after that, I finish activity and then I call it from other activity. and I get error null view child. I don't know why!.
Plz help me.

I'm getting the same issue since switching over to 8.0.0. Changed my @Bind to @BindView and now those Views are null

Did you added the new apt dependency?

[ncapdevi]

I tried adding it, but I'm not sure if it's actually being included. I get the same results whether it's there or not.

I have encountered this problem too.

add apt...

[supercairos]

This will generate the Binding classes that will be called by reflexion by ButterKnife.bind(...)

[simpleton]

plz check below snippet in your build.gradle

dependencies {
  compile 'com.jakewharton:butterknife:8.0.0'
  apt 'com.jakewharton:butterknife-compiler:8.0.0'
}

Hi,

Why we need apt here, any particular reasons?

[JakeWharton]

So that the generated code is created. The compiler is no longer embedded in the runtime.

[JakeWharton]

Look for *$$ViewBinder.java classes in the build/ folder. If they're not there, code generation isn't happening. You can also call ButterKnife.setDebug(true) to see whether it can find the generated classes or not.

It would be nice if bind() caused an exception if the apt dependency is missing.

Is there any option to use ButterKnife with Jack? AFAIK jack doesn't support apt, and I can't compile the project with the plugin :/

No
