Android File Picker🛩️


Well, it doesn’t have a name like Rocky, Cosmos or Fish. Android File Picker, like its name, is a local file selector framework. Some of his characteristics are described below:

  • Launcher in Activity or Fragment
    • Start with a single line of code
  • Browse and select all files in local storage
    • Custom Root path to start
    • Built-in default file type and file discriminator
    • Or you can implement the file type yourself
  • Built in Single Choice mode and Multiple Choice mode.
  • Custom list filter
    • Just want to show pictures(Or videos, audio…)? No problem!
    • Of course, you can just display the folder
  • Custom item click event: only need to implement the listener
  • Apply different themes, including four built-in themes and custom themes
  • More to find out yourself

It depends on your targetAPI:

  • targetAPI <= 28, you are fine ;)
  • targetAPI == 29, please enable requestLegacyExternalStorage feature for your project :D
  • targetAPI >= 30, don’t use this lib. We don’t support scope storage for now :(
    • Unless Google release new external permission or other new feature, we would not consider support scope storage. (or says: “I can’t do this”)
    • Or, ofcouse, you are welcome for give us some ideas. Just create a new issues.



In your project build.gradle:

allprojects {
    repositories {
    	maven { url '' }

In your module build.gradle:

dependencies {
    implementation 'me.rosuh:AndroidFilePicker:$latest_version'

This lib now support AndroidX, check the version below.

Check out releases page to see more versions.

Usage 📑


The library requires two permissions:

  • android.permission.READ_EXTERNAL_STORAGE
  • android.permission.WRITE_EXTERNAL_STORAGE

If you do not have permission to apply, this framework will check and apply at startup.

Launch 🚀 (Kotlin)


Now that you have taken off 🛩️ … ( there are really only two lines )

You only need to add .INSTANCE to use it:


Receive Result

In onActivityResult() callback of the starting Activity or Fragment:

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    when (requestCode) {
        FilePickerManager.instance.REQUEST_CODE -> {
            if (resultCode == Activity.RESULT_OK) {
                val list = FilePickerManager.instance.obtainData()
                // do your work
            } else {
                Toast.makeText(this@SampleActivity, "You didn't choose anything~", Toast.LENGTH_SHORT).show()

The result is a path list of the selected file (ArrayList<String>()).

proguard-rules(For pre v0.5.1)

-keepnames class kotlinx.coroutines.internal.MainDispatcherFactory {}
-keepnames class kotlinx.coroutines.CoroutineExceptionHandler {}
-keepnames class {}
-keepnames class {}

-keepclassmembernames class kotlinx.** {
    volatile <fields>;

Starting with 0.5.2, we removed the coroutine library and implemented it using native threads, so there is no need to add proguard-rules.
