问题 I need to save image in sd_card's pictures directory below Android 10.I have implemented scoped storage & This code works in sdk 29 & above, because MediaStore.getExternalVolumeNames was added in sdk 29. Below sdk 29 how to get getContentUri of sd_card . val values = ContentValues().apply { put(MediaStore.Images.Media.DISPLAY_NAME, destinationFileName) put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg") put(MediaStore.Images.Media.RELATIVE_PATH, Environment.DIRECTORY_PICTURES + File

问题 I am updating my app to use Scoped Storage feature introduced in Android 10. My app works with MediaStore and displays images, videos and audio files and provides ability for user to delete item. What I did earlier to delete file: Got path from MediaStore.MediaColumns.DATA Used new File(path).delete() to delete that file Manually updating MediaStore Now that MediaStore.MediaColumns.DATA is not available I migrated to deleting items from MediaStore using ContentResolver.delete() For example I

问题 In Android 10 apps that need to access storage need to ask permission to concrete path. But apps like file explorer can ask permission for root storage and gain permission to read/write all storage. That is what I am trying. According to Android we must use "ACTION_OPEN_DOCUMENT_TREE" for this. The problem I have is that everything seems correct, but the permission is finally not granted to the app. private void askAndroid10Perm() { Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT_TREE)

问题 Background After migrating to Android Q I can no longer find a suitable way to gain write access to the documents folder ( /storage/emulated/0/Documents ) And before anyone mentions the many other questions on scoped storage I've read through many of them and from what I've seen so far all of the solutions use a app specific directory or accessing a media directory only (not documents folder access). From what I understand in Android Q I can either choose: Use a app specific directory that is

问题 Is there a simple API call that would tell me if an app running on Android 10 or later must use Scoped Storage access, that is, if the normal file access, a.k.a. "Legacy External Storage" is disabled? Note that even if the app in AndroidManifest.xml, section declared: android:requestLegacyExternalStorage="true" the file access may still be denied due to Google policy changes in the future, so testing this value is useless. The only way I found is to test if the external storage root directory

问题 I know it seems like a very basic question, but it's specifically for Android Q. I just want to get an image from Gallery and compress it and send to the server. But because of the Android Q's Scoped Storage, it's harder than I thought. I'll first explain what I did with code: First I send out the intent to pick the image. fun openGallery(fragment: Fragment){ val intent = Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI) intent.type = "*/*" val mimeTypes = arrayOf(
