There’s not that much else to practice, as you’ve mastered nearly everything in Android networking.
Demo
Alright, this request is very similar to how the register or complete note requests work. Start by creating a new class called DeleteNoteResponse, in the model package:
@Serializable
class DeleteNoteResponse(val message: String)
@DELETE("/api/note")
fun deleteNote(@Query("id") noteId: String): Call<DeleteNoteResponse>
fun deleteTask(taskId: String, onTaskDeleted: (Result<String>) -> Unit) {
apiService.deleteNote(taskId).enqueue(object : Callback<DeleteNoteResponse> {
override fun onFailure(call: Call<DeleteNoteResponse>, error: Throwable) {
onTaskDeleted(Failure(error))
}
override fun onResponse(call: Call<DeleteNoteResponse>,
response: Response<DeleteNoteResponse>) {
val completeNoteResponse = response.body()
if (completeNoteResponse?.message == null) {
onTaskDeleted(Failure(NullPointerException("No response!")))
} else {
onTaskDeleted(Success(completeNoteResponse.message))
}
}
})
}
networkStatusChecker.performIfConnectedToInternet {
remoteApi.deleteTask(taskId) { result ->
if (result is Success) {
taskOptionSelectedListener?.onTaskDeleted(taskId)
}
dismissAllowingStateLoss()
}
}
