无法在内部目录中创建文件夹

Question

I am trying to create folder in Android internal storage. For that I am using below code

val path = File(getExternalFilesDir(null),"MyFolder")  

But it is creating folder in Android directory inside app package name under files directory like this: Android/data/com.app.myapp/files/MyFolder . I don't want to create folder like this rather I want to create folder in internal storage like WhatsApp creates.

How can I do this?

Answer 1

So easy, for API level 29 or later :

binding.createFolderButton.setOnClickListener {
    val values = ContentValues()

    values.put(MediaStore.MediaColumns.RELATIVE_PATH, "${Environment.DIRECTORY_DOCUMENTS}/myFolder/")       //folder name

    contentResolver.insert(MediaStore.Files.getContentUri("external"), values)

    Toast.makeText(this, "\"myFolder\" created", Toast.LENGTH_SHORT).show()
}
