My DetailActivity.java file shows an error by not picking ActivityDetailBinding. Other Activity files are working fine and I put;

buildFeatures{
    viewBinding true
}

in build.gradle file before start working on xml files. Only DetailActivity.java file is showing this error.

Error displaying is;

import com.example.juizeesapp.databinding.ActivityDetailBinding; ^ symbol: class ActivityDetailBinding location: package com.example.juizeesapp.databinding

Please look into this help me through this. TIA.

Here is my code.

you have not declared binding ActivityDetailBinding binding;

CodePudding user response：

It was a typo error in the manifest file. I stated .DetailActivity at the manifest file is;

<activity
        android:name=".DetailActivity"
        android:exported="false" />

But when I changed it into;

<activity android:name=".DetailActivity"></activity>

Problem solved.
