Am trying to call a custom dialog box but the app crashes on this line:
cd.show()
This is how I'm calling it:
val cd = CustomDialog(this, applicationContext)
cd.show()
This is the error:
java.lang.IllegalArgumentException: Parameter specified as non-null is null: method kotlin.jvm.internal.Intrinsics.checkParameterIsNotNull, parameter savedInstanceState
I followed this example and it works in java but fails after converting to kotlin
From your linked example:
@Override
protected void onCreate(Bundle savedInstanceState) {
In Kotlin, this should have become
override fun onCreate(savedInstanceState: Bundle?) {
Note the question mark, judging by your error message it's probably missing in your Kotlin code. The type Bundle does not accept null as a legal value (it's non-nullable) and adding a question mark to it broadens it to accept null values.
The activity can be started with no saved instance state, such as when first starting it after installation.
You just need to pass context when initializing CustomDialog.
For example, try this code:
val cd = CustomDialog(this@YourActivity) //Assuming you are initializing it in Activity.
cd.show()
