I am not able to update MediaStore columns of an audio file like title, album , artist of the song, though I request for uri permission using MediaStore.createWriteRequest() and user grants. When I do ContentResolver.update , noOfRowsUpdate is 1, but no changes are applied.
private fun requestWritePermission(uri: Uri){
if (VERSION.SDK_INT >= VERSION_CODES.R) {
val uriList = mutableListOf<Uri>(uri)
val pi = MediaStore.createWriteRequest(contentResolver, uriList)
try {
startIntentSenderForResult(
pi.intentSender, REQUEST_PERM_WRITE, null, 0, 0,
0
)
} catch (e: SendIntentException) {
}
}
}
override fun onActivityResult(requestCode: Int, resultCode: Int, intentData: Intent?) {
if(requestCode == REQUEST_PERM_WRITE && resultCode == Activity.RESULT_OK){
updateAudioTags
}
super.onActivityResult(requestCode, resultCode, intentData)
}
private fun updateAudioTags() {
val uri = ContentUris.withAppendedId(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,
trackId)
val contentValues = ContentValues()
if (hasQ()) {
contentValues.put(MediaStore.Audio.Media.IS_PENDING, 1)
application.contentResolver.update(uri, contentValues, null, null)
}
contentValues.clear()
if (hasQ()) contentValues.put(MediaStore.Audio.Media.IS_PENDING, 0)
contentValues.put(MediaStore.Audio.Media.TITLE, "New title")
contentValues.put(MediaStore.Audio.Media.ALBUM, "New album")
contentValues.put(MediaStore.Audio.Media.ARTIST, "New artist")
val rowsUpdated = application.contentResolver.update(uri, contentValues,
null, null)
Log.i(TAG, "updateAudioTags() :: no of rowsUpdated : $rowsUpdated")
}
(Have raised the issue for the same in google issue tracker - https://issuetracker.google.com/issues/173134422)
