photo picker(android developer link)

 

Before Android 13, you need to request 

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

to access photos or videos.

 

But from Android 13, you can access these media files with [photo picker] without requesting permission.

If you use it, user can choose the files app can access. if you have a experience of iPhone you are familiar with

---

1. You can use [photo picker] if the device meets the following criteria

• Android 11(Api 30) or high
• Receive changes to Modular System Components through Google System Updates

 

The first important thing is that from Android 11, you can use [photo picker] and

you need to use androidx.activity:activity  more than high or equal 1.6.1

 

You can choose either below 

• PickVisualMedia    -> select only on media file
• PickMultipleVisualMedia  -> select multiple meida files

There are examples

// need only one media file
val pickMedia = registerForActivityResult(PickVisualMedia()) { uri ->
    if (uri != null) {
        // success
    } else {
        // no choise
    }
}
// image and video
pickMedia.launch(PickVisualMediaRequest(PickVisualMedia.ImageAndVideo))

// only image
pickMedia.launch(PickVisualMediaRequest(PickVisualMedia.ImageOnly))

// only video
pickMedia.launch(PickVisualMediaRequest(PickVisualMedia.VideoOnly))

// you can set the avilable type
val mimeType = "image/gif"
pickMedia.launch(PickVisualMediaRequest(PickVisualMedia.SingleMimeType(mimeType)))

// If you need to multiple media files
val pickMultipleMedia =
        registerForActivityResult(PickMultipleVisualMedia(5)) { uris ->
.
    if (uris.isNotEmpty()) {
       // Result is list type
    } else {
       // 
    }
}

 

And you can see the result below.

Left is less than Android 13, right is Android 13

 

If you need to check app can use photo picker, you can use this code. 

This code need CompileSdkVersion is 33 or high.

import android.os.ext.SdkExtensions.getExtensionVersion

private fun isPhotoPickerAvailable(): Boolean {
    return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
        true
    } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
        getExtensionVersion(Build.VERSION_CODES.R) >= 2
    } else {
        false
    }
}

fun handlePhotoPickerLaunch() {
    if (isPhotoPickerAvailable()) {
      
    } else {
     
    }
}
