Room SQLite query doesn't return any results, even though there are rows in the database that match

I am using this command to get data from a Room database:
select * from location_search_results where searchQuery = "wilmington"
Here is what the database looks like:
And here are the search results:
I have verified that the name of the table is correct and everything, and there's no spelling errors that I can find, so why would this query not return any of the three rows that it should match?
EDIT for code:
The source code is publicly available here, I am working in the mvvm branch, so if you pull it, make sure you're there. Below are the relevant classes:

override suspend fun searchForLocation(query: String): LiveData<out LocationSearchResponse> {

}
}
}
private fun refreshWeather(latitude: Double, longitude: Double) = launch {
weatherViewModel.refreshWeatherWithCoordinates(latitude, longitude)
}
}

It turns out there was a space being added to the end of the searchQuery that I wasn't able to see. Once I figured out where my code was adding that space, I removed it and now everything looks good.

try something like this
it`s a dao interface example
use big letters in your query
#Query("SELECT * FROM person WHERE favoriteColor LIKE :color")
List<Person> getAllPeopleWithFavoriteColor(String color);

Android Coroutines block UI click listener

I'm using MVVM as architecture, also the repository pattern. I have a Web service, a room database also. Using coroutines block any button I click.
There's a list/detail implemented with a fragment and an activity respectively.
I can figure out what's wrong in the way I implemented the coroutines and Viewmodel.
class BuySharedViewModel(application: Application) : AndroidViewModel(application) {
private val repository: BuyRepository
var allBuys: LiveData<List<Buy>>
init {
val buyDao = KunukRoomDatabase.getDatabase(application, viewModelScope).buyDao()
val buyRemote = BuyRemote()
repository = BuyRepository.getInstance(buyDao , buyRemote)
//Use async because it return a result
viewModelScope.launch { getAllBuys() }
allBuys = buyDao.loadAllBuys()
}
private suspend fun getAllBuys() {
repository.getBuys()
}
}
Here's is the Repository, it take data from web service and add it to the room database, while ViewModel get's data from room database.
class BuyRepository (private val buyDao: BuyDao, private val buyRemote: BuyRemote) {
private val job = SupervisorJob()
private val scope = CoroutineScope(Dispatchers.Default + job)
companion object {
//For singleton instantiation
#Volatile private var instance: BuyRepository? = null
fun getInstance(buyDao: BuyDao, buyRemote: BuyRemote) =
instance ?: synchronized(this) {
instance ?: BuyRepository(buyDao, buyRemote)
.also { instance = it}
}
}
suspend fun getBuys(){
refresh()
}
private suspend fun refresh(){
try {
val list = scope.async { buyRemote.loadBuys() }
list.await().forEach { buy -> insert(buy) }
} catch (e: Throwable) {}
}
#WorkerThread
private fun insert(buy: Buy) {
buyDao.insertBuy(buy)
}
}
The fragment work, data are displayed, when i click on an item from that fragment(recyclerView) it work, the activity display details data. But none of the click on that activity works, like it doesn't detect the clicks. I guess it got something to do with the coroutines because when I comment out the code viewmodelScope.launch { getAllBuys()} from the BuySharedViewModel it works, because it load data from the previous call from room database, and the clicks works.
Here's the code in the detail view:
class BuyDetailActivity : AppCompatActivity() {
private lateinit var sharedViewModel: BuySharedViewModel
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
lateinit var buy: Buy
sharedViewModel = ViewModelProviders.of(this).get(BuySharedViewModel::class.java)
val position = intent.getIntExtra("position", 0)
sharedViewModel.allBuys.observe(this, Observer<List<Buy>> { buys ->
buy = buys[position]
val binding: com.example.drake.kunuk.databinding.ActivityBuyDetailBinding =
DataBindingUtil.setContentView(this, com.example.drake.kunuk.R.layout.activity_buy_detail)
binding.buy = buy
val agentNumber = buy.agentNumber?:"+50937438713"
bnvContactAgent.setOnNavigationItemSelectedListener { item ->
when (item.itemId) {
com.example.drake.kunuk.R.id.action_call -> {
val callNumberUri = Uri.parse("tel:$agentNumber")
val callIntent = Intent(Intent.ACTION_DIAL, callNumberUri)
startActivity(callIntent)
}
com.example.drake.kunuk.R.id.action_sms -> {
val smsNumberUri = Uri.parse("sms:$agentNumber")
val smsIntent = Intent(Intent.ACTION_SENDTO, smsNumberUri)
startActivity(smsIntent)
}
com.example.drake.kunuk.R.id.action_email -> {
val uriText = "mailto:drakecolin#gmail.com" +
"?subject=" + Uri.encode("I'm interested in $agentNumber") +
"&body=" + Uri.encode("Hello, ")
val uri = Uri.parse(uriText)
val sendIntent = Intent(Intent.ACTION_SENDTO)
sendIntent.data = uri
startActivity(Intent.createChooser(sendIntent, "Send email"))
}
}
false
}
This is the code of my fragment:
class BuyFragment : Fragment() {
companion object {
fun newInstance() = BuyFragment()
}
private lateinit var viewModel: BuySharedViewModel
private val buyList = ArrayList<Buy>()
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
// Get a new or existing ViewModel from the ViewModelProvider.
viewModel = ViewModelProviders.of(this).get(BuySharedViewModel::class.java)
// Add an observer on the LiveData returned by loadAllBuys.
// The onChanged() method fires when the observed data changes and the activity is
// in the foreground.
viewModel.allBuys.observe(this, Observer<List<Buy>> { buys ->
// Update the cached copy of the words in the adapter.
buys?.let { (rvBuy.adapter as BuyAdapter).setBuys(it) }
progressBar.visibility = View.GONE
})
}
override fun onCreateView(
inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
return inflater.inflate(R.layout.buy_fragment, container, false)
}
override fun onActivityCreated(savedInstanceState: Bundle?) {
super.onActivityCreated(savedInstanceState)
rvBuy.layoutManager = LinearLayoutManager(context)
rvBuy.adapter = BuyAdapter(activity!!.applicationContext,
R.layout.buy_card, buyList)
progressBar.visibility = View.VISIBLE
}
}
This is the code for the BuyDao:
#Dao
interface BuyDao {
#Insert(onConflict = OnConflictStrategy.REPLACE)
fun insertBuy(vararg buys: Buy)
#Update
fun updateBuy(vararg buys: Buy)
#Delete
fun deleteBuys(vararg buys: Buy)
#Query("SELECT * FROM buys")
fun loadAllBuys(): LiveData<List<Buy>>
#Query("DELETE FROM buys")
suspend fun deleteAll()
}

viewModelScope by default uses Dispatchers.Main and it is blocking your UI.
Try this:
viewmodelScope.launch(Dispatchers.IO) { getAllBuys()}
Edit:
The problem is your setting listner on BottomNavigation when your livedata is updated which is causing this weird issue.
Replace your BuyDetailActivity code with this:
class BuyDetailActivity : AppCompatActivity() {
private lateinit var sharedViewModel: BuySharedViewModel
private var agentNumber = ""
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
val binding: ActivityBuyDetailBinding =
DataBindingUtil.setContentView(this, R.layout.activity_buy_detail)
binding.buy = Buy()
lateinit var buy: Buy
sharedViewModel = ViewModelProviders.of(this).get(BuySharedViewModel::class.java)
val position = intent.getIntExtra("position", 0)
sharedViewModel.allBuys.observe(this, Observer<List<Buy>> { buys ->
buy = buys[position]
binding.buy = buy
binding.executePendingBindings()
agentNumber = buy.agentNumber
// set animation duration via code, but preferable in your layout files by using the animation_duration attribute
expandableTextView.setAnimationDuration(750L)
// set interpolators for both expanding and collapsing animations
expandableTextView.setInterpolator(OvershootInterpolator())
// or set them separately.
expandableTextView.expandInterpolator = OvershootInterpolator()
expandableTextView.collapseInterpolator = OvershootInterpolator()
// toggle the ExpandableTextView
buttonToggle.setOnClickListener {
buttonToggle.setText(if (expandableTextView.isExpanded) com.example.drake.kunuk.R.string.more else com.example.drake.kunuk.R.string.less)
expandableTextView.toggle()
}
// but, you can also do the checks yourself
buttonToggle.setOnClickListener {
if (expandableTextView.isExpanded) {
expandableTextView.collapse()
buttonToggle.setText(com.example.drake.kunuk.R.string.more)
} else {
expandableTextView.expand()
buttonToggle.setText(com.example.drake.kunuk.R.string.less)
}
}
//Open photoView activity when clicked
ivHouseDetail.setOnClickListener {
applicationContext
.startActivity(
Intent(
applicationContext,
ViewPagerActivity::class.java
)
.putExtra("imageList", buy.propertyImage)
.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
)
}
})
findViewById<BottomNavigationView>(R.id.bnvContactAgent)?.setOnNavigationItemSelectedListener { item ->
when (item.itemId) {
R.id.action_call -> {
Log.e("BIRJU", "Action call")
val callNumberUri = Uri.parse("tel:$agentNumber")
val callIntent = Intent(Intent.ACTION_DIAL, callNumberUri)
startActivity(callIntent)
}

And the ApiInterface class to receive it. Being the url I want to get is:
#GET("server.php?action=getResultados&cmp=328{jor}tmp=2018/2019") fun
getTodasJuvenil(
#Path("jor") jornada: String ): Call<List<TodasModel>>
The url I want to get is:
"server.php?action=getResultados&cmp=328&jor=1&tmp=2018/2019"
this is the error:
java.lang.IllegalArgumentException: URL query string
"action=getResultados&cmp=328{jor}&tmp=2018/2019" must not have
replace block. For dynamic query parameters
at com.myapplication.Jornadas.FragJornadas.getData(FragJornadas.kt:91)
at
com.myapplication.Jornadas.FragJornadas.onViewCreated(FragJornadas.kt:87)

Using #Path you're telling retrofit to replace that variable in the path of the url, but you want in the query string. The path is the bit after the domain and before the query string - in your case would be server.php and maybe some bits that come before, which I can't say without seeing the full url.
To add a parameter to the query string you want to use #Query and you don't want to specify it in the query string in the #GET annotation. So you could change things to:
#GET("server.php?action=getResultados&cmp=328&tmp=2018/2019") fun
getTodasJuvenil(
#Query("jor") jornada: String ): Call<List<TodasModel>>)
You've removed {jor} from the query string and replaced #Path with #Query.
Now, retrofit should add a query parameter with the desired jornada.

#Fred thanks for your answers, my mistake was not the previous one, I was not deleting the list, it was added at the end, the solution is:
dataList.clear()
override fun onResponse(call: Call<List<TodasModel>>?, response: Response<List<TodasModel>>?) {
dataList.clear()
dataList.addAll(response!!.body()!!)
recyclerView.adapter!!.notifyDataSetChanged()
}

How can i refrence variable inside outer class (kotlin)

How can i reference the SongName variable in my other object? I am building my first app with Kotlin so I am really beginner.
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
SpotifyService.connect(this) {
spotifyAppRemote?.let {
it.playerApi.subscribeToPlayerState().setEventCallback {
val track: Track = it.track
Log.d("MainActivity", track.name + " by " + track.artist.name)
ALabel.text = track.name
Blabel.text = track.artist.name
var SongName = track.name
var SongArtist = track.artist.name
}
}
}
GeniusApi.PrintSomething()
}
}``` ```object GeniusApi {
val BASE_URL = "https://api.genius.com"
val SEARCH_URL = BASE_URL + "/search"
var DATA = SongName#MainActivity
fun PrintSomething() {
Log.e("GeniusApi", DATA)
}
}```

On your Kotlin file you will need to place any functions or variables inside a
Companion Object {
lateinit var myobject
}
And then reference it like
TheObject.Companion.myobject
