App crash when i use VideoUIKit-Android Agora

when i build smaple project , app has been crashed
when i see logcat , i see this:
90-30676/io.agora.agora_android_uikit E/agora.io: jni_generator_helper.h: (line 131): android.view.ViewRootImpl$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views.
what do i do ?

} else {
val joinButton = Button(this)
// this#MainActivity.runOnUiThread(java.lang.Runnable {
runOnUiThread {
Runnable { joinButton.text = "Allow Camera and Microphone, then click here" }
}
// })
joinButton.setOnClickListener {
if (AgoraVideoViewer.requestPermission(this)) {
// (joinButton.parent as ViewGroup).removeView(joinButton)
agView!!.join("test", role = Constants.CLIENT_ROLE_BROADCASTER)
}
}
// joinButton.setBackgroundColor(Color.GREEN)
// joinButton.setTextColor(Color.RED)
this.addContentView(
joinButton,
FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, 300)
)
}
}
i want to solve my issue

Please wrap with function and make annotations there instead of mentioning in the main content view and wrap using UI thread.And refer sample github agora sdk github for reference - https://github.com/AgoraIO-Community/VideoUIKit-Android

(Kotlin) Number guessing game doesn't register the correct userInput. Any tips?

Super new to kotlin. My code seems to be bugging out at this line:
else if (userInput == randomNumber){
message = "Horray! You got it!\n Play again?"
}
Seems like a quick fix but I'm not sure...When I input according to the hint, it doesn't register the correct answer at all. It's stuck on "higher/lower" and gives no option for the game to end. I'll attach the entire thing if it helps:
Thanks so much in advance.

Login button needs to be clicked twice to login

i'm making an app on AndroidStudio and I need to verify credentials when they log in to the app. The app works with an API and to verifiy credentials i created this function in the database to check someones email and password:
(postgresql)
create or replace function login (emailf text, passwordf text)
returns boolean
language plpgsql
as
$$
declare pp text;
begin
pp = (select pass_w from utilizador where utilizador.email = emailf);
if (pp = passwordf) then return true;
else return false;
end if; end
$$
I'm parsing the data through this CheckLoginas function:
var bola: Boolean? = null
fun CheckLoginas(c: Context?, email: String, pass: String): Boolean? {
var mQueue: RequestQueue
mQueue = Volley.newRequestQueue(c);
var url = "https://myurl.com" + "/utilizador/login/" + email + "/" + pass
val request = JsonArrayRequest(Request.Method.GET, url, null, Response.Listener {
response ->try {
var jsonArray = JSONArray()
jsonArray = response.getJSONArray(0)
for (i in 0 until jsonArray.length())
{
val jsonObject : JSONObject? = jsonArray.getJSONObject(i)
//val user = jsonArray.getJSONObject(i)
//val bool = jsonObject.getBoolean("login")
val boo : Boolean = jsonObject!!.getBoolean("login")
println("im inside CheckLoginas boo $boo\n\n")
bola = boo
}
} catch (e: JSONException) {
e.printStackTrace()
}
}, Response.ErrorListener { error -> error.printStackTrace() })
mQueue?.add(request)
return bola
}
'bola' variable is a global variable because I needed to return a boolean from the function so I can know if the credentials check (or not) in another activity.
The Problem:
To login when the credentials are correct, I have to press twice in the login button. If the email and password are correct, the first time I press it gives me the "Wrong credentials" error and in the second time it logs in. I already tried to do it with a while(), I checked it step by step and it seems fine, nothing seems to work to fix this error... The function works, the API too, and the app itself kinda works too, it just has this bug of clicking twice on the button... This is the activity code:
package com.example.crowdzero
import CheckLoginas
import Database
import android.content.Intent
import android.os.Bundle
import android.view.View.OnFocusChangeListener
import android.widget.Button
import android.widget.Toast
import androidx.appcompat.app.AppCompatActivity
import com.google.android.material.textfield.TextInputLayout
import java.lang.Thread.sleep
class Login : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_login)
val log_in_btn_log_in = findViewById<Button>(R.id.log_in_btn_log_in)
val log_in_btn_registar = findViewById<Button>(R.id.log_in_btn_registar)
log_in_btn_log_in.setOnClickListener {
verificacao()
}
log_in_btn_registar.setOnClickListener {
val intent = Intent(this, Registo::class.java)
startActivity(intent)
}
}
private fun verificacao() {
val log_in_input_text_email = findViewById<TextInputLayout>(R.id.log_in_input_text_email)
val log_in_input_text_password = findViewById<TextInputLayout>(R.id.log_in_input_text_password)
val string_email = log_in_input_text_email?.getEditText()?.getText().toString()?.trim()
val string_password = log_in_input_text_password?.getEditText()?.getText().toString()?.trim()
if (string_email.isNullOrEmpty())
{
log_in_input_text_email.setError(" ")
}
else if (string_password.isNullOrEmpty())
{
log_in_input_text_password.setError(" ")
}
else
{
val email = log_in_input_text_email.editText?.text.toString()
val password = log_in_input_text_password.editText?.text.toString()
//var baca = CheckLoginas(this,email,password)
println(email)
println(password)
var baca: Boolean? = null
baca = CheckLoginas(this, email, password)
//baca = CheckLoginas(this,email,password)
if (baca == false) {
//Toast.makeText(this, "Esta conta não está registada", Toast.LENGTH_SHORT).show();
println("Im inside if in login baca $baca")
} else if (baca == true) {
Toast.makeText(this, email, Toast.LENGTH_SHORT).show();
Toast.makeText(this, password, Toast.LENGTH_SHORT).show();
val intent = Intent(this, Home::class.java)
startActivity(intent)
finish()
}
}
}
}
When I test this with an actual email and password from the database, baca variable stays false when it should be true, since CheckLoginas boo var is true. This is what is causing the problem.
image that shows it
I'm fairly new to the Database-API-App thing, so please forgive me if its a trivial thing

You are calling baca = CheckLoginas(this, email, password)
baca will not update immedietly, the next line if (baca == false) will be executed before you API response arrives, so after you got some response baca becomes true. This is why you need to click twice.

SOLVED:
I pretty much inserted the CheckLoginas function inside the login.kt file. It works now! It looks like this now:

PowerMock `thenReturn` doesn't return expected data for mocked static method?

I am able to tun my test but it fails. The problem is, mocked method is still returning wrong data. This is my method that I want to test it:
fun getTextByLanguage(list: List<TitleModel>) : String {
val deviceLanguage = Locale.getDefault().language
var default = ""
for (item in list) {
if (item.culture.contains(deviceLanguage, true)) return item.value
if (item.culture.contains("en", true)) default = item.value
}
return default
}
And this is how I am testing the method:
import junit.framework.TestCase.assertEquals
import org.junit.Test
import org.junit.runner.RunWith
import org.powermock.api.mockito.PowerMockito.*
import org.powermock.core.classloader.annotations.PrepareForTest
import org.powermock.modules.junit4.PowerMockRunner
import java.util.Locale
#RunWith(PowerMockRunner::class)
#PrepareForTest(Locale::class)
class AppConfigUtilityByPowerMockTest {
#Test
fun `getTextByLanguage, test en`() {
mockStatic(Locale::class.java)
val mockedLocal = mock(Locale::class.java)
`when`(Locale.getDefault()).thenReturn(mockedLocal)
`when`(mockedLocal.language).thenReturn("en")
val list = listOf(TitleModel("en-ca", "Home"), TitleModel("fr-ca", "HomeFr"))
val actual = getTextByLanguage(list)
assertEquals("Home", actual)
}
#Test
fun `getTextByLanguage, test fr`() {
mockStatic(Locale::class.java)
val mockedLocal = mock(Locale::class.java)
`when`(Locale.getDefault()).thenReturn(mockedLocal)
`when`(mockedLocal.language).thenReturn("fr")
val list = listOf(TitleModel("en-ca", "Home"), TitleModel("fr-ca", "HomeFr"))
val actual = getTextByLanguage(list)
assertEquals("HomeFr", actual)
}
}
The first test cases without problem but the second one fails. This is the out put:
junit.framework.ComparisonFailure: expected:<Home[Fr]> but was:<Home[]>
Expected :HomeFr
Actual :Home

One way to answer the question is to get rid of Local class from the method and do stuff in Kotlin way. So, what I did is to change my original method like this:
fun getTextByLanguage(list: List<TitleModel>, deviceLanguage: String = getDeviceLanguage()) : String {
var default = ""
for (item in list) {
if (item.culture.contains(deviceLanguage, true)) return item.value
if (item.culture.contains("en", true)) default = item.value
}
return default
}
fun getDeviceLanguage(): String {
return Locale.getDefault().language
}
Now my test class looks like this:
import junit.framework.TestCase.assertEquals
import org.junit.Test
import org.junit.runner.RunWith
import org.powermock.core.classloader.annotations.PrepareForTest
import org.powermock.modules.junit4.PowerMockRunner
import java.util.Locale
#RunWith(PowerMockRunner::class)
#PrepareForTest(Locale::class)
class AppConfigUtilityByPowerMockTest {
#Test
fun `getTextByLanguage, test en`() {
val list = listOf(TitleModel("en-ca", "Home"), TitleModel("fr-ca", "HomeFr"))
val actual = getTextByLanguage(list, "en")
assertEquals("Home", actual)
}
#Test
fun `getTextByLanguage, test fr`() {
val list = listOf(TitleModel("en-ca", "Home"), TitleModel("fr-ca", "HomeFr"))
val actual = getTextByLanguage(list, "fr")
assertEquals("HomeFr", actual)
}
}
Although my test passes, I am still willing to see your recommendation and down to accept your answer to my question.
