Choose file in external storage and get path - kotlin

Question

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)
}
