Debug is working but release not - Kotlin receives data via Bluetooth - kotlin

I am working on Bluetooth receiving and sending data. I can send data via Bluetooth but it doesn't work the receive data. I want to get string data and split it. And the split data will show the list view. Since data import is not working, I created string data and called the split method, but it didn't work here either in a release. Can you help me?
Here are my Activity codes;
var mUUID: UUID = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB")

Log.d("mesajBT", "onCreate: mesaj gonderildi")
}
val string2: String = "deneme, deneme02K, deneme90,klm08B,bitti."
splitList(string2)
}
private fun sendCommand(input: String) {
if (mBluetoothSocket != null) {
try {
mBluetoothSocket!!.outputStream.write(input.toByteArray())
} catch (e: IOException) {
e.printStackTrace()
}
}
}
fun run() {
val LOGTAG: String ="ReadListString"
Log.i(LOGTAG, Thread.currentThread().name)
val buffer = ByteArray(8)
var bytes: Int
val text1: TextView = binding.text2
var readText : String
Log.d("mesajBt", "mesaj metodu")
//Loop to listen for received bluetooth messages
if (mBluetoothSocket != null) {
while (true) {
bytes = try {
bytes = inputStream.read(buffer) ?:0
readText = String(buffer, 0, bytes)

} catch (e: IOException) {

Log.e("TAG", "splitList: $list ")
val list2: ArrayList<String> = ArrayList(list)
textView.text = list2.toString()
}
arrayAdapter = ArrayAdapter(this, android.R.layout.simple_list_item_1, list)
listView.adapter=arrayAdapter

Since there will be commas between words in data coming from Bluetooth, I used a comma as a separator in the split method. After some research, I corrected a few mistakes. You can change the value of the bytes as 8-16-32-64 according to the incoming data type and size.
Receive method is here
private fun run() {
//Loop to listen for received bluetooth messages
if (mBluetoothSocket != null) {
val TAG: String = "ReadList-run"
Log.i(TAG, Thread.currentThread().name)
val buffer = ByteArray(1024)
var bytes: Int
var readText: String
Log.e("mesajBt", "mesaj metodu")
while (true) {
try {
bytes = inputStream.read(buffer)
readText = String(buffer, 0, bytes)
Log.e("Arduino Message", readText)
splitlist(readText)
break
} catch (e: IOException) {
e.printStackTrace()
Log.d("Else", "message alinamadi.")
break
}
}
}
}
Here is my split method
fun splitList(output: String) {
if (mBluetoothSocket != null) {
try {
val list: List<String> = output.split(",").toList()
for (it in list) {
Log.e("TAG", "splitList: $list ")
}
} catch (e: IOException) {
e.printStackTrace()
}
// [A, B, C, D]
}
}

How to save text file in a document directory with Kotlin while using Jetpack with the same format? [duplicate]

I wrote an App, in Kotlin with Android Studio that write some strings to a file.
All work, I can write and read inside the App, but I can't see the file looking in Documents folder.
How can I use the folder Documents as a storage space?
Thank you
These are the function I use:
fun saveTextFile(view: View, nomeFile: String, testo: String, contesto: Context){
var fileStream: FileOutputStream
try {
fileStream = contesto.openFileOutput(nomeFile, MODE_APPEND) // OK esegue append
fileStream.write(testo.toByteArray())
fileStream.close()
}catch (e: Exception){
e.printStackTrace()
}
}
fun readTextFile(view: View, nomeFile: String, contesto: Context): String{
var fileInputStream: FileInputStream? = null
fileInputStream = contesto.openFileInput(nomeFile)
var inputStreamReader: InputStreamReader = InputStreamReader(fileInputStream)
val bufferedReader: BufferedReader = BufferedReader(inputStreamReader)
val stringBuilder: StringBuilder = StringBuilder()
var text: String? = null
while ({ text = bufferedReader.readLine(); text }() != null) {
stringBuilder.append(text)
}
inputStreamReader.close();
return(stringBuilder.toString())
}
Thank you, Livio
For writing in Documents folder of your device , you just need to make use of MediaStore for the same. You can take input for this function anything that you want like String , bitmap , PdfDocument and other's too .
For Your UseCase you can do the following ,
Global Variable :
private var imageUri: Uri? = null
override suspend fun saveDocument(context : Context, text : String) {
withContext(Dispatchers.IO) {
try {
val collection =
MediaStore.Files.getContentUri(MediaStore.VOLUME_EXTERNAL_PRIMARY)
val dirDest = File(
Environment.DIRECTORY_DOCUMENTS,
context.getString(R.string.app_name)
)
val date = System.currentTimeMillis()
val fileName = "$date.txt"
val contentValues = ContentValues().apply {
put(MediaStore.MediaColumns.DISPLAY_NAME, fileName)
put(MediaStore.MediaColumns.RELATIVE_PATH,
"$dirDest${File.separator}")
put(MediaStore.Files.FileColumns.IS_PENDING, 1)
}
}
val imageUri = context.contentResolver.insert(collection, contentValues)
withContext(Dispatchers.IO) {
imageUri?.let { uri ->
context.contentResolver.openOutputStream(uri, "w").use { out -> out?.write(text.toByteArray())
}
contentValues.clear()
contentValues.put(MediaStore.Files.FileColumns.IS_PENDING, 0)
context.contentResolver.update(uri, contentValues, null, null)
}
}
} catch (e: FileNotFoundException) {
null
}
}
}
For Updating the already existing file , do the following . After creating file for the first time I have saved the imageUri in a global variable (If you want to store it permanently / or for a while you can use Jetpack Datastore / Shared Preference to save the same ):
suspend fun updateData(context: Context,text : String){
withContext(Dispatchers.IO) {
try {
val collection =
MediaStore.Files.getContentUri(MediaStore.VOLUME_EXTERNAL_PRIMARY)
val dirDest = File(
Environment.DIRECTORY_DOCUMENTS,
context.getString(R.string.app_name)
)
val fileName = "test.txt"
val contentValues = ContentValues().apply {
put(MediaStore.MediaColumns.DISPLAY_NAME, fileName)
put(
MediaStore.MediaColumns.RELATIVE_PATH,
"$dirDest${File.separator}"
)
put(MediaStore.Files.FileColumns.IS_PENDING, 1)
}
withContext(Dispatchers.IO) {
imageUri?.let { uri ->
context.contentResolver.openOutputStream(uri, "wa").use { out ->
out?.write(text.toByteArray())
}
contentValues.clear()
contentValues.put(MediaStore.Files.FileColumns.IS_PENDING, 0)
context.contentResolver.update(uri, contentValues, null, null)
}
}
} catch (e: FileNotFoundException) {
null
}
}
}
For Reading the File , Do the following :
suspend fun read(context: Context, source: Uri): String = withContext(Dispatchers.IO) {
val resolver: ContentResolver = context.contentResolver
resolver.openInputStream(source)?.use { stream -> stream.readText() }
?: throw IllegalStateException("could not open $source")
}
private fun InputStream.readText(charset: Charset = Charsets.UTF_8): String =
readBytes().toString(charset)
This is how the final code looks like :
class MainActivity : AppCompatActivity() {
private lateinit var btn: Button
private var imageUri: Uri? = null
private lateinit var btn2: Button
private lateinit var btn3 : Button
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
btn = findViewById(R.id.btnAdd)
btn2 = findViewById(R.id.getText)
btn3 = findViewById(R.id.updateText)
btn.setOnClickListener {
lifecycleScope.launch {
saveDocument(applicationContext, "Original ")
}
}
btn3.setOnClickListener {
lifecycleScope.launch {
updateData(applicationContext,"Appended")
}
}
btn2.setOnClickListener {
lifecycleScope.launch {
imageUri?.let { it1 ->
val data = read(applicationContext, it1)
Toast.makeText(applicationContext, "The data is $data ", Toast.LENGTH_LONG)
.show()
}
}
}
}
suspend fun saveDocument(context: Context, text: String) {
withContext(Dispatchers.IO) {
try {
val collection =
MediaStore.Files.getContentUri(MediaStore.VOLUME_EXTERNAL_PRIMARY)
val dirDest = File(
Environment.DIRECTORY_DOCUMENTS,
context.getString(R.string.app_name)
)
val date = System.currentTimeMillis()
val fileName = "test.txt"
val contentValues = ContentValues().apply {
put(MediaStore.MediaColumns.DISPLAY_NAME, fileName)
put(
MediaStore.MediaColumns.RELATIVE_PATH,
"$dirDest${File.separator}"
)
put(MediaStore.Files.FileColumns.IS_PENDING, 1)
}
imageUri = context.contentResolver.insert(collection, contentValues)
withContext(Dispatchers.IO) {
imageUri?.let { uri ->
context.contentResolver.openOutputStream(uri, "w").use { out ->
out?.write(text.toByteArray())
}
contentValues.clear()
contentValues.put(MediaStore.Files.FileColumns.IS_PENDING, 0)
context.contentResolver.update(uri, contentValues, null, null)
}
}
} catch (e: FileNotFoundException) {
null
}
}
}
suspend fun updateData(context: Context, text: String) {
withContext(Dispatchers.IO) {
try {
val collection =
MediaStore.Files.getContentUri(MediaStore.VOLUME_EXTERNAL_PRIMARY)
val dirDest = File(
Environment.DIRECTORY_DOCUMENTS,
context.getString(R.string.app_name)
)
val fileName = "test.txt"
val contentValues = ContentValues().apply {
put(MediaStore.MediaColumns.DISPLAY_NAME, fileName)
put(
MediaStore.MediaColumns.RELATIVE_PATH,
"$dirDest${File.separator}"
)
put(MediaStore.Files.FileColumns.IS_PENDING, 1)
}
withContext(Dispatchers.IO) {
imageUri?.let { uri ->
context.contentResolver.openOutputStream(uri, "wa").use { out ->
out?.write(text.toByteArray())
}
contentValues.clear()
contentValues.put(MediaStore.Files.FileColumns.IS_PENDING, 0)
context.contentResolver.update(uri, contentValues, null, null)
}
}
} catch (e: FileNotFoundException) {
null
}
}
}
suspend fun read(context: Context, source: Uri): String = withContext(Dispatchers.IO) {
val resolver: ContentResolver = context.contentResolver
resolver.openInputStream(source)?.use { stream -> stream.readText() }
?: throw IllegalStateException("could not open $source")
}
private fun InputStream.readText(charset: Charset = Charsets.UTF_8): String =
readBytes().toString(charset)
I have three buttons . With the first I create a file , then the uri gets stored in the global variable . Then onClick of second button I add to the already existing file and then read the file using the third button using the same imageUri stored in the global variable
This is the demo for the same . Check when the buttons are being pressed and the output in the form of Toast at the bottom .

Remote Mediator loads only the first page

I'm trying to add offline capabilities to my TMDB app. I've tried doing it with Room but RemoteMediator only loads the first page.
This is how I implemented the RemoteMediator class
#OptIn(ExperimentalPagingApi::class)
class MoviesPopularMediator(
private val service: ApiService,
private val database: PopularMoviesDatabase
) : RemoteMediator<Int, MoviesModel>() {
override suspend fun load(
loadType: LoadType,
state: PagingState<Int, MoviesModel>
): MediatorResult {
return try {
val loadKey = when(loadType){
LoadType.REFRESH -> {
1
}
LoadType.PREPEND -> return MediatorResult.Success(endOfPaginationReached = true)
LoadType.APPEND ->{
state.lastItemOrNull()
?: return MediatorResult.Success(endOfPaginationReached = true)
getMoviesPage()
}
}
val response = service.getPopular(
page = state.config.pageSize,
)
val listing = response.body()
val results = listing?.results
if (listing != null) {
database.withTransaction {
if (loadKey != null) {
database.popularMoviesPageDao().savePopularMoviesPage(MoviesPage(page = listing.page, results = listing.results, total_pages = listing.total_pages))
}
if (results != null) {
database.popularMoviesDao().savePopularMovies(results)
}
}
}
MediatorResult.Success(endOfPaginationReached = response.body()?.page == response.body()?.total_pages)
} catch (exception: IOException) {
MediatorResult.Error(exception)
} catch (exception: HttpException) {
MediatorResult.Error(exception)
}
}
private suspend fun getMoviesPage(): MoviesPage? {
return database.popularMoviesPageDao().getPopularMoviesPage().firstOrNull()
}
}
I get the data from this api: https://api.themoviedb.org/3/.
Any ideas on how I should change this RemoteMediator so that it will load all pages?
If you need more details please feel free to ask

Choose file in external storage and get path

i know this question has been asked several times but everything i can find is only in Java and not very relevant to me...
I'm trying to select a file when i click on a button in my app (images or videos like : /storage/emulated/0/Download/giphy.gif ) and the when the picture or video is selected, i need the path to go inside an edittext.
I have found that code in kotlin for path :
class URIPathHelper {
fun getPath(context: Context, uri: Uri): String? {
val isKitKatorAbove = true
// DocumentProvider
if (isKitKatorAbove && DocumentsContract.isDocumentUri(context, uri)) {
// ExternalStorageProvider
if (isExternalStorageDocument(uri)) {
val docId = DocumentsContract.getDocumentId(uri)
val split = docId.split(":".toRegex()).toTypedArray()
val type = split[0]
if ("primary".equals(type, ignoreCase = true)) {
return Environment.getExternalStorageDirectory().toString() + "/" + split[1]
}
} else if (isDownloadsDocument(uri)) {
val id = DocumentsContract.getDocumentId(uri)
val contentUri = ContentUris.withAppendedId(Uri.parse("content://downloads/public_downloads"), java.lang.Long.valueOf(id))
return getDataColumn(context, contentUri, null, null)
} else if (isMediaDocument(uri)) {
val docId = DocumentsContract.getDocumentId(uri)
val split = docId.split(":".toRegex()).toTypedArray()
val type = split[0]
var contentUri: Uri? = null
if ("image" == type) {
contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI
} else if ("video" == type) {
contentUri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI
} else if ("audio" == type) {
contentUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI
}
val selection = "_id=?"
val selectionArgs = arrayOf(split[1])
return getDataColumn(context, contentUri, selection, selectionArgs)
}
} else if ("content".equals(uri.scheme, ignoreCase = true)) {
return getDataColumn(context, uri, null, null)
} else if ("file".equals(uri.scheme, ignoreCase = true)) {
return uri.path
}
return null
}
fun getDataColumn(context: Context, uri: Uri?, selection: String?, selectionArgs: Array<String>?): String? {
var cursor: Cursor? = null
val column = "_data"
val projection = arrayOf(column)
try {
cursor = uri?.let { context.getContentResolver().query(it, projection, selection, selectionArgs,null) }
if (cursor != null && cursor.moveToFirst()) {
val column_index: Int = cursor.getColumnIndexOrThrow(column)
return cursor.getString(column_index)
}
} finally {
if (cursor != null) cursor.close()
}
return null
}
fun isExternalStorageDocument(uri: Uri): Boolean {
return "com.android.externalstorage.documents" == uri.authority
}
fun isDownloadsDocument(uri: Uri): Boolean {
return "com.android.providers.downloads.documents" == uri.authority
}
fun isMediaDocument(uri: Uri): Boolean {
return "com.android.providers.media.documents" == uri.authority
}
}
And this is what i'm trying :
binding.redloader.setOnClickListener {
val uriPathHelper = URIPathHelper()
val filePath: String? = uriPathHelper.getPath(this, MediaStore.Images.Media.EXTERNAL_CONTENT_URI)
val uri: Uri = Uri.parse(filePath)
val intent = Intent(Intent.ACTION_VIEW)
intent.type = "image/*"
intent.putExtra(Intent.ACTION_VIEW, uri)
startActivity(Intent.createChooser(intent, "Open file"))
binding.redgif.setText(filePath)
}
When I click on the button it automatically chooses the first picture in the storage, and then it opens google picture but I cannot do anything except watch the pictures...
I'm sorry I know they are some stupid things in my code, I think I have something to do with intent but all I see on the internet is calling private void and it is not working for me...
I'm a complete beginner and I really hope someone can help me...
Update with what i'm trying, i think i'm close :
binding.redloader.setOnClickListener {
val uriPathHelper = URIPathHelper()
intent = Intent(Intent.ACTION_GET_CONTENT)
intent.type = "image/*"
intent.addCategory(Intent.CATEGORY_OPENABLE)
intent = Intent.createChooser(intent, "Choose a file")
val resultLauncher =
registerForActivityResult(ActivityResultContracts.StartActivityForResult()) { result ->
if (result.resultCode == Activity.RESULT_OK) {
val data: Intent? = result.data
if (data != null) {
val fileUri: Uri? = data.data
Log.i(LOG_TAG, fileUri.toString())
var fileURIPathHelper: String? = null
try {
fileURIPathHelper = uriPathHelper.getPath(this, EXTERNAL_CONTENT_URI)
} catch (e: Exception) {
Log.e(LOG_TAG, "Error: " + e)
Toast.makeText(this, "Error: " + e, Toast.LENGTH_SHORT).show()
}
this.binding.redgif.setText(fileURIPathHelper)
}
}
}
resultLauncher.launch(intent)
}
I solved it ! :)
val resultLauncher =
registerForActivityResult(ActivityResultContracts.StartActivityForResult()) { result ->
if (result.resultCode == Activity.RESULT_OK) {
val data: Intent? = result.data
if (data != null) {
val fileUri: Uri? = data.data
Log.i(PackageManagerCompat.LOG_TAG, fileUri.toString())
val contentUri: String?
try {
contentUri = uriPathHelper.getPath(this, fileUri!!)
this.binding.redgif.setText(contentUri)
} catch (e: Exception) {
Log.e(PackageManagerCompat.LOG_TAG, "Error: " + e)
Toast.makeText(this, "Error: " + e, Toast.LENGTH_SHORT).show()
}
}
}
}
binding.redloader.setOnClickListener {
val intent = Intent(Intent.ACTION_GET_CONTENT)
intent.type = "image/*"
intent.addCategory(Intent.CATEGORY_OPENABLE)
startActivity(Intent.createChooser(intent, "Open file"))
resultLauncher.launch(intent)
}

Kotlin -Coroutine request won't wait till first request finish

I have 2 requests: SIGNUP and SIGNUP_UPLOAD_AVATAR
#POST(SIGNUP)
fun registerUser(#QueryMap(encoded = true) userCredentials: HashMap<String, Any>): Deferred<Response<UserResponse>>
#Multipart
#POST(SIGNUP_UPLOAD_AVATAR) //SHOULD BE A PUT, DUE TO ONLY SEND FILE.
fun uploadAvatar(#Part file: MultipartBody.Part): Deferred<Response<ResponseBody>>
currently i decided to change for the use of COROUTINES however im having an issue, that is when the first post SIGNUP_UPLOAD_AVATAR start his request, i need to wait till it finish to go with the SIGNUP process. However the second coroutine start immediately, without asking if the first request finish or is still working.
This is my function:
fun getImageUrlCoRoutine(){
val requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), profilePicture)
val body = MultipartBody.Part.createFormData("file", "android.${getFileExtension(profilePicture)}", requestFile)
val service = APIService.create()
val request = service.uploadAvatar(body)
try {
GlobalScope.launch(Dispatchers.Main) {
val response = CoroutineUtil().retryIO (times = 3){ request.await() }
val responseCode = StatusCode(response.code()).description
when(responseCode){
StatusCode.Status.OK -> {
response.body()?.let {
it.let {
println("RESULT: " + it.string())
avatarUrl = it.string()
println("Avatar: " + avatarUrl)
registrationCoroutine(this) <- here goes for the second request(registration)
}
}
}
else -> {}
}
}
}catch (e: HttpException){
val responseCode = StatusCode(e.code()).description
when(responseCode){
StatusCode.Status.NotAcceptable -> {
}
else -> {
}
}
}catch (e: Throwable){
println("Houston we got a Coroutine Problem")
println(e)
}
}
fun registrationCoroutine(suspended: CoroutineScope) {
val service = APIService.create()
val data = HashMap<String, Any>()
data["email"] = email
data["phone"] = phoneNumber
data["username"] = email
data["password"] = password
data["fullName"] = fullname
data["token"] = ""
data["appName"] = BuildConfig.APP_NAME
data["avatarUrl"] = avatarUrl
data["deviceType"] = BuildConfig.PLATFORM
data["needsVerify"] = false
suspended.launch {
val request = service.registerUser(data)
try {
val response = CoroutineUtil().retryIO(times = 3) { request.await() }
val responseCode = StatusCode(response.code()).description
when(responseCode){
StatusCode.Status.OK -> {
response.body()?.let {
it.let {
println(it)
}
}
}
else -> {}
}
} catch (e: HttpException) {
val responseCode = StatusCode(e.code()).description
when(responseCode){
StatusCode.Status.NotAcceptable -> {}
else -> {}
}
} catch (e: Throwable) {
println("Houston we have a coroutine problem")
println(e)
}
}
}
and the responses that i get...

Problems adding values to ArrayList

I'm trying to add url values (imgURL variable) taken from JSON into an ArrayList with Kotlin, but somehow when in the scope of the for loop it doesn't seem to work regardless of having my newArrayURLs array declared as a function variable. Any ideas why is this?
private fun getJsonObjectImg(Url: String): ArrayList<String>{
var paths: ArrayList<String> =ArrayList()
val params = HashMap<String, String>()
var newArrayURLs = ArrayList<String>()
val stringRequest = object : StringRequest(Request.Method.POST, Url, Response.Listener { s ->
try {
val array = JSONObject(s)
var imagesArray = array.getJSONArray("images")
for(i in 0..imagesArray.length() -1 ){
var imgURL = imagesArray.getJSONObject(i).getString("fileName")
newArrayURLs.add(imgURL)
paths.add(imgURL)
}
Log.d("pathsin TRY", paths.count().toString())
} catch(e:JSONException){
Log.d("ERROR------", e.toString())
null
}
}, Response.ErrorListener {
error: VolleyError? ->
try {
Log.d("ERROR======","V")
} catch (e: JSONException){
e.printStackTrace()
}
}) {
override fun getParams(): Map<String, String> = mapOf("uploadedBy" to id)
}
val requestQueue = Volley.newRequestQueue(this)
requestQueue.add<String>(stringRequest)
return newArrayURLs
}
