I want to load all the pictures from the galley to my app by using MediaStore.MediaColumns.DATA , but it is deprecated. So, what is the other way to load them?
I use this
Loading images from internal store.Reading all folders which has images and videos using MediaStore class.
And returning result as ArrayList.
private fun getAllShownImagesPath(activity: Activity): ArrayList<Albums> {
val uri: Uri
val cursor: Cursor
var cursorBucket: Cursor
val column_index_data: Int
val column_index_folder_name: Int
val listOfAllImages = ArrayList<String>()
var absolutePathOfImage: String? = null
var albumsList = ArrayList<Albums>()
var album: Albums? = null
val BUCKET_GROUP_BY = "1) GROUP BY 1,(2"
val BUCKET_ORDER_BY = "MAX(datetaken) DESC"
uri = android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI
val projection = arrayOf(MediaStore.Images.ImageColumns.BUCKET_ID,
MediaStore.Images.ImageColumns.BUCKET_DISPLAY_NAME,
MediaStore.Images.ImageColumns.DATE_TAKEN,
MediaStore.Images.ImageColumns.DATA)
cursor = activity.contentResolver.query(uri, projection, BUCKET_GROUP_BY, null, BUCKET_ORDER_BY)
if (cursor != null) {
column_index_data = cursor.getColumnIndexOrThrow(MediaStore.MediaColumns.DATA)
column_index_folder_name = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.BUCKET_DISPLAY_NAME)
while (cursor.moveToNext()) {
absolutePathOfImage = cursor.getString(column_index_data)
Log.d("title_apps", "bucket name:" + cursor.getString(column_index_data))
val selectionArgs = arrayOf("%" + cursor.getString(column_index_folder_name) + "%")
val selection = MediaStore.Images.Media.DATA + " like ? "
val projectionOnlyBucket = arrayOf(MediaStore.MediaColumns.DATA, MediaStore.Images.Media.BUCKET_DISPLAY_NAME)
cursorBucket = activity.contentResolver.query(uri, projectionOnlyBucket, selection, selectionArgs, null)
Log.d("title_apps", "bucket size:" + cursorBucket.count)
if (absolutePathOfImage != "" && absolutePathOfImage != null) {
listOfAllImages.add(absolutePathOfImage)
albumsList.add(Albums(cursor.getString(column_index_folder_name), absolutePathOfImage, cursorBucket.count, false))
}
}
}
return getListOfVideoFolders(albumsList)
}
// This function is resposible to read all videos from all folders.
private fun getListOfVideoFolders(albumsList: ArrayList<Albums>): ArrayList<Albums> {
var cursor: Cursor
var cursorBucket: Cursor
var uri: Uri
val BUCKET_GROUP_BY = "1) GROUP BY 1,(2"
val BUCKET_ORDER_BY = "MAX(datetaken) DESC"
val column_index_album_name: Int
val column_index_album_video: Int
uri = android.provider.MediaStore.Video.Media.EXTERNAL_CONTENT_URI
val projection1 = arrayOf(MediaStore.Video.VideoColumns.BUCKET_ID,
MediaStore.Video.VideoColumns.BUCKET_DISPLAY_NAME,
MediaStore.Video.VideoColumns.DATE_TAKEN,
MediaStore.Video.VideoColumns.DATA)
cursor = this.contentResolver.query(uri, projection1, BUCKET_GROUP_BY, null, BUCKET_ORDER_BY)
if (cursor != null) {
column_index_album_name = cursor.getColumnIndexOrThrow(MediaStore.Video.Media.BUCKET_DISPLAY_NAME)
column_index_album_video = cursor.getColumnIndexOrThrow(MediaStore.Video.Media.DATA)
while (cursor.moveToNext()) {
Log.d("title_apps", "bucket video:" + cursor.getString(column_index_album_name))
Log.d("title_apps", "bucket video:" + cursor.getString(column_index_album_video))
val selectionArgs = arrayOf("%" + cursor.getString(column_index_album_name) + "%")
val selection = MediaStore.Video.Media.DATA + " like ? "
val projectionOnlyBucket = arrayOf(MediaStore.MediaColumns.DATA, MediaStore.Video.Media.BUCKET_DISPLAY_NAME)
cursorBucket = this.contentResolver.query(uri, projectionOnlyBucket, selection, selectionArgs, null)
Log.d("title_apps", "bucket size:" + cursorBucket.count)
albumsList.add(Albums(cursor.getString(column_index_album_name), cursor.getString(column_index_album_video), cursorBucket.count, true))
}
}
return albumsList
}
I managed to come up with the following solution, its kind of an addition to the previous answer
but there I still couldn't load images with the obtained Uri. Documentation suggested to use openFileDescriptor() which I did and then decoded images' bitmaps from it:
override fun loadImagesFromStorage(): List<AdapterImage> {
val uri: Uri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI
val cursor: Cursor?
val columnIndexId: Int
val listOfAllImages = mutableListOf<AdapterImage>()
val projection = arrayOf(MediaStore.Images.Media._ID)
cursor = context.contentResolver
.query( uri, projection, null, null, null)
if ( cursor != null ){
columnIndexId = cursor.getColumnIndexOrThrow(MediaStore.Images.Media._ID)
while (cursor.moveToNext()){
val contentUri = ContentUris.withAppendedId(uri, cursor.getLong(columnIndexId))
//here I open FileDescriptor and then decode it into Bitmap
var image: Bitmap
context.contentResolver.openFileDescriptor(contentUri, "r").use { pfd ->
if( pfd != null ){
image = BitmapFactory.decodeFileDescriptor(pfd.fileDescriptor)
listOfAllImages.add(AdapterImage(image))
}
}
}
cursor.close()
}
return listOfAllImages
}
P.S. My method will return a list of AdapterImage objects that I use later in app but you can put anything you need there at this point
I was able to replace MediaStore.MediaColumns.Data with its own file ID (incredibly, files have IDs) and correctly constructing its URI, like this:
fun getAllShownImagesPath(activity: Activity): MutableList<Uri> {
val uriExternal: Uri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI
val cursor: Cursor?
val columnIndexID: Int
val listOfAllImages: MutableList<Uri> = mutableListOf()
val projection = arrayOf(MediaStore.Images.Media._ID)
var imageId: Long
cursor = activity.contentResolver.query(uriExternal, projection, null, null, null)
if (cursor != null) {
columnIndexID = cursor.getColumnIndexOrThrow(MediaStore.Images.Media._ID)
while (cursor.moveToNext()) {
imageId = cursor.getLong(columnIndexID)
val uriImage = Uri.withAppendedPath(uriExternal, "" + imageId)
listOfAllImages.add(uriImage)
}
cursor.close()
}
return listOfAllImages
}
and then with Uri you build it in your Views!
I finally solved the problem by creating this class
class FileHelper {
val mediaType = "multipart/form-data".toMediaTypeOrNull()
fun getPartBodyFromUri(context: Context, uri: Uri): MultipartBody.Part {
val realPath = getPathFromURI(context, uri)
val fileImage = createFile(realPath)
val requestBody = createRequestBody(fileImage)
return createPart(fileImage, requestBody)
}
private fun createFile(realPath: String): File {
return File(realPath)
}
private fun createRequestBody(file: File): RequestBody {
return file.asRequestBody(mediaType)
}
private fun createPart(file: File, requestBody: RequestBody): MultipartBody.Part {
return MultipartBody.Part.createFormData("imageFile", file.name, requestBody)
}
private fun getPathFromURI(context: Context, uri: Uri): String {
var realPath = String()
uri.path?.let { path ->
val databaseUri: Uri
val selection: String?
val selectionArgs: Array<String>?
if (path.contains("/document/image:")) { // files selected from "Documents"
databaseUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI
selection = "_id=?"
selectionArgs = arrayOf(DocumentsContract.getDocumentId(uri).split(":")[1])
} else { // files selected from all other sources, especially on Samsung devices
databaseUri = uri
selection = null
selectionArgs = null
}
try {
val column = "_data"
val projection = arrayOf(column)
val cursor = context.contentResolver.query(
databaseUri,
projection,
selection,
selectionArgs,
null
)
cursor?.let {
if (it.moveToFirst()) {
val columnIndex = cursor.getColumnIndexOrThrow(column)
realPath = cursor.getString(columnIndex)
}
cursor.close()
}
} catch (e: Exception) {
println(e)
}
}
return realPath
}
}
Media.DATA it's deprecate and "MediaStore.Images.Media._ID" to get the correct column, not working so I create column I need
val column = "_data"
val projection = arrayOf(column)
then I use getColumnIndexOrThrow() method to get correct index
val columnIndex = cursor.getColumnIndexOrThrow(column)
realPath = cursor.getString(columnIndex)
