I'm new in Kotlin, i want to create an android mobile app.I use Android studio 3.3,the Android API level 28. I have used a swagger to get all my RESTful web service, thus, i have the android-client-generated the file that contains all the web service. As a start, I created an android interface for authentication with Email and Password". Among the web service available, "apiMobileUsersGetByFireBaseIDGet". This Ws, use the firebase Id to authenticate. I create a kotlin class AUthentication as the following
class Authentication : AppCompatActivity() {
var fireBaseAuthentication = FirebaseAuth.getInstance()
private var mobileApi: MobileApi? = null
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
JodaTimeAndroid.init(this)
setContentView(R.layout.activity_authentication)
mobileApi = MobileApi()
buttonLogin.setOnClickListener {
signIn(editTextEmail.text.toString(), editTextPassword.text.toString())
}
txtViewSignUp.setOnClickListener {
var intent = Intent(this, Register::class.java)
startActivity(intent)
overridePendingTransition(R.anim.slide_right_in, R.anim.slide_left_out)
}
}
private fun verifyAvailableNetwork(activity: AppCompatActivity): Boolean {
val connectivityManager = activity.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
val networkInfo = connectivityManager.activeNetworkInfo
return networkInfo != null && networkInfo.isConnected
}
private fun signIn(email: String, password: String) {
showMessage("Authenticating...")
fireBaseAuthentication.signInWithEmailAndPassword(email, password).addOnCompleteListener { task ->
if (task.isSuccessful) {
GlobalScope.launch(Dispatchers.IO) {
val user = fireBaseAuthentication.currentUser?.uid?.let { mobileApi!!.apiMobileUsersGetByFireBaseIDGet(it) }//////////////////////
withContext(Dispatchers.Main) {
println(user!!.fireBaseID)
println(user!!.email)
var intent = Intent(this@Authentication, MainActivity::class.java)
intent.apply {
putExtra("id", user.fireBaseID)
putExtra("email", user.email)*/
}
startActivity(intent)
}
}
} else {
showMessage("Error: ${task.exception?.message}")
}
}
}
private fun showMessage(message: String) {
Toast.makeText(this, message, Toast.LENGTH_LONG).show()
}
i added alse the internet permission in the AndroidManifest.xml. My problem is when i run my app in my mobile phone, an error. I tried to use the ThreeTenABP library and jodatime library but the error still persist java.lang.ClassNotFoundException: Didn't find class "java.time.LocalDateTime", the error is ddescribe as the following
