5. Built in photo pickers in OS. Using this picker doesn’t require READ_STORAGE permission. Photo Picker
6. photo_picker.kt //If version > 13 val intent = Intent(MediaStore.ACTION_PICK_IMAGES) //Setup picker config //Launch Picker startActivityForResult(intent, PHOTO_PICKER_REQUEST_CODE)
7. photo_picker.kt //If version > 13 val intent = Intent(MediaStore.ACTION_PICK_IMAGES) //Setup max count int maxCount = 5; intent.putExtra(MediaStore.EXTRA_PICK_IMAGES_MAX, maxCount) //Launch Picker startActivityForResult(intent, PHOTO_PICKER_REQUEST_CODE)
8. photo_picker.kt //If version > 13 val intent = Intent(MediaStore.ACTION_PICK_IMAGES) //Setup max count int maxCount = 5; intent.putExtra(MediaStore.EXTRA_PICK_IMAGES_MAX, maxCount) //Set to video only intent.type = "video/*" //Launch Picker startActivityForResult(intent, PHOTO_PICKER_REQUEST_CODE)
9. photo_picker.kt override fun onActivityResult(...) { //if result ok when (requestCode) { REQUEST_PHOTO_PICKER_SINGLE_SELECT -> { val currentUri: Uri = data.data // Do stuff with the photo/video URI. } REQUEST_PHOTO_PICKER_MULTI_SELECT -> { // Get photo picker response for multi select. data.clipData.forEach { clipData -> val uri = clipData.uri // Do stuff with the photo/video URI. } } } }
10. photo_picker.kt override fun onActivityResult(...) { //if result ok when (requestCode) { REQUEST_PHOTO_PICKER_SINGLE_SELECT -> { val currentUri: Uri = data.data // Do stuff with the photo/video URI. } REQUEST_PHOTO_PICKER_MULTI_SELECT -> { // Get photo picker response for multi select. data.clipData.forEach { clipData -> val uri = clipData.uri // Do stuff with the photo/video URI. } } } }
11. photo_picker.kt override fun onActivityResult(...) { //if result ok when (requestCode) { REQUEST_PHOTO_PICKER_SINGLE_SELECT -> { val currentUri: Uri = data.data // Do stuff with the photo/video URI. } REQUEST_PHOTO_PICKER_MULTI_SELECT -> { // Get photo picker response for multi select. data.clipData.forEach { clipData -> val uri = clipData.uri // Do stuff with the photo/video URI. } } } }
