I added the request premissions for reading files tried this method inside my activity but nothing shows,like there is no images in real devices and emulator,what am i doing wrong?
fun storaheread() {
val imageProjection = arrayOf(
MediaStore.Images.Media.DISPLAY_NAME,
MediaStore.Images.Media.SIZE,
MediaStore.Images.Media.DATE_TAKEN,
MediaStore.Images.Media._ID
)
val imageSortOrder = "${MediaStore.Images.Media.DATE_TAKEN} DESC"
val cursor = contentResolver.query(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
imageProjection,
null,
null,
imageSortOrder
)
cursor.use {
it?.let {
val idColumn = it.getColumnIndexOrThrow(MediaStore.Images.Media._ID)
val nameColumn = it.getColumnIndexOrThrow(MediaStore.Images.Media.DISPLAY_NAME)
val sizeColumn = it.getColumnIndexOrThrow(MediaStore.Images.Media.SIZE)
val dateColumn = it.getColumnIndexOrThrow(MediaStore.Images.Media.DATE_TAKEN)
while (it.moveToNext()) {
val id = it.getLong(idColumn)
val name = it.getString(nameColumn)
val size = it.getString(sizeColumn)
val date = it.getString(dateColumn)
val contentUri = ContentUris.withAppendedId(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
id
)
// add the URI to the list
// generate the thumbnail
// val thumbnail = (this as Context).contentResolver.loadThumbnail(contentUri, Size(480, 480), null)
Log.d("image name",name)
}
} ?: kotlin.run {
Log.e("TAG", "Cursor is null!")
}
}
}
