Problem with changing sound alarm in Kotlin when I already reselect audio from external storage

I want to try to make alarm Android app experiment in Kotlin so it can change audio sound from external storage, say that I already set the "A" audio sound for alarm sound from the external storage. Then, I want to change audio input sound that set into "B" audio sound for alarm sound from the external storage by reselecting it. The problem is, when I already change the audio input for alarm sound from audio "A" to audio "B" by reselecting it, audio "A" (previous audio) still playing the alarm sound instead of audio "B".
So this is the select audio button : (ignore the requestPermission(), supposse the permission is granted)
binding.selectAudio.setOnClickListener()
{
if (checkPermission())
{
openAudio()
}
else
{
requestPermission()
}
}
This is when the app redirected into selecting audio sound and get the path on it:
private fun openAudio()
{
//soundPath = null
onStop()
val openFileIntent = Intent(Intent.ACTION_GET_CONTENT)
openFileIntent.type = "audio/*"
getResult.launch(openFileIntent)
}
private val getResult =
registerForActivityResult(ActivityResultContracts.StartActivityForResult())
{
soundPath = null
if (it.resultCode == RESULT_OK)
{
val uri: Uri? = it.data!!.data
File(uri!!.getPath())
val path = getRealPath(this, uri)
soundPath = path
if (soundPath != null)
{
Toast.makeText(this, "Audio file has been set", Toast.LENGTH_SHORT).show()
}
}
}
This is the set alarm button :
binding.setAlarmBtn.setOnClickListener()
{
createNotificationChannel(soundPath)
setAlarm()
Log.e("notif", "soundpath" + soundPath.toString())
Log.d("soundPath", soundPath.toString())
}
This is the process of setting alarm into certain time :
private fun setAlarm()
{
try
{
alarmManager = getSystemService(ALARM_SERVICE) as AlarmManager
val intent = Intent(this, AlarmReceiver::class.java)
pendingIntent = PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_IMMUTABLE)
alarmManager[AlarmManager.RTC_WAKEUP, calendar.timeInMillis] = pendingIntent
Toast.makeText(this, "Alarm set successfully", Toast.LENGTH_SHORT).show()
}
catch (e: Exception)
{
Toast.makeText(this, "Time is not been set", Toast.LENGTH_SHORT).show()
}
}
And finally this is when alarm is playing through notification as well as get audio uri path after input audio sound :
private fun createNotificationChannel(path: String?)
{
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)
{
val uri = getUri(path)
val attributes = AudioAttributes.Builder().setUsage(AudioAttributes.USAGE_ALARM).build()
val name : CharSequence = "AlarmReminderChannel"
val description = "Channel For Alarm Manager"
val importance = NotificationManager.IMPORTANCE_HIGH
val channel = NotificationChannel("alarmManagerDemo", name, importance)
channel.description = description
channel.setSound(uri, attributes)
Log.e("notif", "uri" + uri.toString())
Log.e("notif", "uri from channel" + channel.sound.toString())
val notificationManager = getSystemService(NotificationManager::class.java)
notificationManager.createNotificationChannel(channel)
}
}
private fun getUri(path: String?) : Uri?
{
Log.e("notif", "path: "+path )
if(path == null)
{
Log.e("notif", "null" )
return Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://" + this.packageName + "/raw/music")
}
else
{
Log.e("notif", "tidak null" )
return Uri.parse(path)
}
}
Also, this is the onReceive sound from BroadcastReceiver :
class AlarmReceiver : BroadcastReceiver()
{
override fun onReceive(context: Context?, intent: Intent?)
{
val bundle : Bundle? = intent!!.extras
val i = Intent(context, DestinationActivity::class.java)
intent!!.flags = Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TASK
val pendingIntent = PendingIntent.getActivity(context, 0, i, PendingIntent.FLAG_IMMUTABLE)
val builder = NotificationCompat.Builder(context!!, "alarmManagerDemo")
.setSmallIcon(R.drawable.ic_launcher_background)
.setContentTitle("Demo")
.setContentText("Bla bla bla bla bla bla bla bla")
.setAutoCancel(true)
.setDefaults(NotificationCompat.DEFAULT_ALL)
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setContentIntent(pendingIntent)
val notificationManager = NotificationManagerCompat.from(context)
notificationManager.notify(123, builder.build())
}
}
So, how do I solve this to make the alarm sound changed when the alarm is playing new input sound instead of previous input sound?

Android doesn't permit updating the sound of the notification channel by recreating it. You should first delete exist channel, and after create the new.
So, try it:
private fun createNotificationChannel(path: String?) {
...
val notificationManager = getSystemService(NotificationManager::class.java)
notificationManager.deleteNotificationChannel("alarmManagerDemo")
notificationManager.createNotificationChannel(channel)
}

Android Package Manager install not showing

I'm trying to build an auto updater via github. The app so far detects new available versions and downloads the apk file. I however cannot get it to install the apk file.
There are no crashes or Log messages indicating an error. The install dialog just does not show up.
This is my code:
fun downloadAndInstall(link: Uri, fileName: String){
val downloadManager = context.getSystemService(Context.DOWNLOAD_SERVICE) as DownloadManager
val downloadUri = link
val request = DownloadManager.Request(downloadUri)
request.setMimeType(MIME_TYPE)
val destination = context.getExternalFilesDir(Environment.DIRECTORY_DOWNLOADS).toString() + "/" + fileName
val destinationUri = Uri.parse("file://$destination")
request.setDestinationUri(destinationUri)
fun showInstallOption(destination: String) {
val onComplete = object : BroadcastReceiver() {
override fun onReceive(
context: Context,
intent: Intent
) {
val contentUri = FileProvider.getUriForFile(
context,
BuildConfig.APPLICATION_ID + ".provider",
File(destination)
)
val installer = context.packageManager.packageInstaller
val resolver = context.contentResolver
resolver.openInputStream(contentUri)?.use { apkStream ->
val length =
DocumentFile.fromSingleUri(context, contentUri)?.length() ?: -1
val params =
PackageInstaller.SessionParams(PackageInstaller.SessionParams.MODE_FULL_INSTALL)
val sessionId = installer.createSession(params)
val session = installer.openSession(sessionId)
session.openWrite("INSTALL", 0, length).use { sessionStream ->
apkStream.copyTo(sessionStream)
session.fsync(sessionStream)
}
val intent = Intent(context, InstallReceiver::class.java)
intent.action = "com.blazecode.tsviewer.util.updater.SESSION_API_PACKAGE_INSTALLED"
val pi = PendingIntent.getBroadcast(
context,
3,
intent,
PendingIntent.FLAG_UPDATE_CURRENT or PendingIntent.FLAG_IMMUTABLE
)
session.commit(pi.intentSender)
session.close()
}
Toast.makeText(context, "done", Toast.LENGTH_LONG).show()
}
}
context.registerReceiver(onComplete, IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE))
}
showInstallOption(destination)
downloadManager.enqueue(request)
Toast.makeText(context, context.getString(R.string.downloading), Toast.LENGTH_LONG).show()
}
I tested this on Android 13 and 8, both with the same result. Android 13 is a physical device. Android 8 is an emulator.

How to open a file in another app via an Intent using an URI?

In my app, I have several file Uri (NOT URI) store. These are of the form:
content://com.android.providers.downloads.documents/document/427
My intention is, once I click a button, open one of these Uri in a file reader (may it be MS Word, Excel, PDF Reader... depending on the extension and device).
I am currently trying this snippet:
val file = File(Uri.parse(uri).path!!)
val myMime: MimeTypeMap = MimeTypeMap.getSingleton()
val newIntent = Intent(Intent.ACTION_VIEW)
val mimeType: String = myMime.getMimeTypeFromExtension(file.extension).toString()
newIntent.setDataAndType(
FileProvider.getUriForFile(applicationContext, "${applicationContext.packageName}.provider", file), mimeType)
newIntent.flags = Intent.FLAG_ACTIVITY_NEW_TASK
newIntent.flags = Intent.FLAG_GRANT_READ_URI_PERMISSION
try {
startActivity(newIntent)
} catch (e: ActivityNotFoundException) {
}
But every time I try to open it, I get:
java.lang.IllegalArgumentException: Failed to find configured root that contains /document/427
Could you please tell me what am I missing? No answers I've found here targeted my problem. Thanks in advance!
UPDATE
Thanks to #CommonsWare help, I managed to avoid an Exception, my code now looks like this:
val newIntent = Intent(Intent.ACTION_VIEW)
newIntent.addCategory(Intent.CATEGORY_OPENABLE)
newIntent.data = Uri.parse(uri)
newIntent.flags = Intent.FLAG_ACTIVITY_NEW_TASK
newIntent.flags = Intent.FLAG_GRANT_READ_URI_PERMISSION
try {
startActivity(newIntent)
} catch (e: ActivityNotFoundException) {
Toast.makeText(this, e.toString(), Toast.LENGTH_LONG).show()
}
I'm getting the Uri from here:
val fileResultLauncher = registerForActivityResult(ActivityResultContracts.StartActivityForResult()) { result ->
viewModel.uploadFile(result, false)
}
fileFab.setOnClickListener {
val intent = Intent()
intent.type = "application/*"
intent.action = Intent.ACTION_OPEN_DOCUMENT
fileResultLauncher.launch(intent)
}
Unfortunately, I'm getting a NoActivityFoundException

Get rid of:
val file = File(Uri.parse(uri).path!!)
...and replace your setDataAndType() call with:
newIntent.setDataAndType(Uri.parse(uri), mimeType)

Kotlin - How can open a csv file via Intent using default apps?

My android app flow is as follows:
Creates a csv file.
Store it in the default app folder.
Generates a notification of succesful creation
Open the csv in the default app.
I can not be able to open the csv via Intent or other methods so far.
With the following code I'm able to open the explorer but not in the folder path.
var path = this.applicationContext.getExternalFilesDir(null)?.absolutePath.toString()
println("Hey my path is $path")
val csvWriter = CSVWriter(
fileWriter,
CSVWriter.DEFAULT_SEPARATOR,
CSVWriter.NO_QUOTE_CHARACTER,
CSVWriter.DEFAULT_ESCAPE_CHARACTER,
CSVWriter.DEFAULT_LINE_END
)
csvWriter.writeAll(data.toMutableList())
csvWriter.close()
val intent = Intent(Intent.ACTION_OPEN_DOCUMENT).apply {
addCategory(Intent.CATEGORY_OPENABLE)
type = "application/*"
}
startActivityForResult(intent, 2)
Also, I tried to develop a function but without effective response:
fun open_file(filename: String?) {
val path = File(filesDir, "dl")
val file = File(path, filename)
// Get URI and MIME type of file
val uri = FileProvider.getUriForFile(this, "$PACKAGE_NAME.fileprovider", file)
val mime = contentResolver.getType(uri)
// Open file with user selected app
val intent = Intent()
intent.action = Intent.ACTION_VIEW
intent.setDataAndType(uri, mime)
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
startActivity(intent)
}
I saw some possible solutions developed in java but there are deprecated and / or does not work converted in Kotlin.
Edit:
Given the suggestion of #CommonsWare, I'm trying to save the file in the path given but the user. However, I get the error : No Activity found to handle Intent
val FILE_EXPORT_REQUEST_CODE = 12
val exportIntent = Intent(Intent.ACTION_CREATE_DOCUMENT)
exportIntent.addCategory(Intent.CATEGORY_OPENABLE)
exportIntent.type = "text/csv"
val uri = Uri.parse("$path/file.csv")
exportIntent.data = uri
val filename = "file.csv"
exportIntent.putExtra(Intent.EXTRA_TITLE, filename)
startActivityForResult(exportIntent, FILE_EXPORT_REQUEST_CODE)
Thanks in advance.

Please help me anyone i spent more time for this issue.

I found that desktop shortcut is not created in default launcher of vivo devices. When I changed default launcher to some other launcher It's let me create desktop shortcut. So as far I did R&d I found below solution it's not complete solution but you can redirect to allow Desktop shortcuts screen using below code.
val sintent = Intent()
sintent .addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
sintent .component = ComponentName("com.bbk.launcher2", "com.bbk.launcher2.installshortcut.PurviewActivity")
activity.startActivity(sintent )
I tried to get result if user allowed or not but it's not work for all VIVO devices.
var uri = Uri.parse("content://com.bbk.launcher2.settings/favorites")
var query = activity.contentResolver.query(uri, null, " itemType = ?", arrayOf("30"), null);
if (query != null && query.count > 0) {
var idIndex = query.getColumnIndexOrThrow("_id");
var intentIndex = query.getColumnIndexOrThrow("intent");
var shortcutPermissionIndex = query.getColumnIndexOrThrow("shortcutPermission");
while (query.moveToNext()) {
val long = query.getLong(idIndex)
val intent = query.getString(intentIndex)
val shortcutPermission = query.getInt(shortcutPermissionIndex)
var unflattenFromString = ComponentName.unflattenFromString(intent)
Log.e("bhavin->", "initView: getShortcutPerBtn id=$long packageName= ${unflattenFromString!!.packageName} shortcutPermission= $shortcutPermission")
if (unflattenFromString!!.packageName == activity.packageName && shortcutPermission != 0 && shortcutPermission != 16){
val intent = Intent()
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
intent.component = ComponentName("com.bbk.launcher2", "com.bbk.launcher2.installshortcut.PurviewActivity")
activity.startActivity(intent)
query.close()
return#ensureBackgroundThread
}
else{
Log.e("bhavin->","abcd")
}
}
query.close()
}
For more details you can check this I found this git
Note: I found exception some devices vivo 1902 and Z3
java.lang.SecurityException: Permission Denial: opening provider
com.bbk.launcher2.data.LauncherProvider from ProcessRecord{f8f30af

If any one found how to check desktop permission is allowed in Vivo devices please add into this answer.
