Binary XML file line #22: Error inflating class fragment

Question

I'm doing a training program in which there is a list of questions that can be answered Yes or no. Depending on the answer text to the question changes color. The results should be displayed in a separate activity. I suggested to use fragments to save what is the color of the text issue but I have them an error Binary XML file line #22: Error inflating class fragment

Here is the code:

        setContentView(R.layout.activity_main);

        {
            iResult = savedInstanceState.getIntArray(KEY);
        }
        mResult = (Button) findViewById(R.id.result);
        mResult.setOnClickListener(new View.OnClickListener() {

Answer 1

So after several weeks I found the problem. While updating to Sceneform SDK 1.16 there's a breaking change you guys. Minor version bump but that causes those crashes I cite in my question. The solution is:

1. Follow the steps in the README of the Sceneform SDK repo (copy over two src directories into your source code, modify two build files).
2. Remove the existing com.google.ar.sceneform.ux:sceneform-ux:1.x reference from your build.gradle file
3. Refactor those two directories from the SDK to use androidx imports in case your project is not relying on the old AppCompat ones.

See also my blog post about it: https://csaba.page/blog/sceneform-breaking-change.html

Answer 2

Fragments can't be added using xml.
You need to add it using fragment manager by doing fragment transaction in activity or some other fragment.

In your example it's unnecessary to use fragment, as it contains only single TextView.

You can replace your fragment tag in item xml with a TextView directly.
