## Dependencies used
```groovy
// Kotlin Coroutine
implementation 'androidx.activity:activity-ktx:1.4.0'
// Image Cropper
api 'com.theartofdev.edmodo:android-image-cropper:2.8.0'
```
### Integration Step Used Binding in Kotlin
1. Add **viewBinding `true`** `build.gralde (Module)`
```groovy
android {
...
buildFeatures {
viewBinding true
}
}
```
2. Activity Kotlin Class
```kotlin
class MainActivity : AppCompatActivity() {
/** Add this */
private lateinit var binding: ActivityMainBinding
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
/** Add this */
binding = ActivityMainBinding.inflate(layoutInflater)
/** Change this */
setContentView(binding.root)
/** Without findViewById */
binding.textView.text = "Bye bye findViewById"
}
}
```
3. Activity Java Class
```java
public class MainActivity extends AppCompatActivity {
/** Add this */
private ActivityMainBinding binding;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
/** Add this */
binding = ActivityMainBinding.inflate(getLayoutInflater());
/** Change this */
setContentView(binding.getRoot());
/** Without findViewById */
binding.textView.setText("Bye bye findViewById");
}
}
```
**binding** in kotlin can be used directly without initializing **findViewById** on widgets in layout xml
