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

    <application
      ...
      android:requestLegacyExternalStorage="true"
    </application>

Code

first, you must to check user permissions:

private val REQUEST_EXTERNAL_PERMISSION_CODE = 666
    private var PERMISSIONS_EXTERNAL_STORAGE =
        arrayOf(READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE)

    private fun checkPermission(permissions: Array<String>) {
        if (ContextCompat.checkSelfPermission(
                this@AutoUpdateExample,
                permissions[0]
            ) == PackageManager.PERMISSION_DENIED
            || ContextCompat.checkSelfPermission(
                this@AutoUpdateExample,
                permissions[1]
            ) == PackageManager.PERMISSION_DENIED
        ) {

            ActivityCompat.requestPermissions(
                this@AutoUpdateExample,
                PERMISSIONS_EXTERNAL_STORAGE,
                REQUEST_EXTERNAL_PERMISSION_CODE
            )
        } else {
            Toast.makeText(this@AutoUpdateExample, "Permission already granted", Toast.LENGTH_SHORT).show()
            runUpdater()
        }
    }

override fun onRequestPermissionsResult(
        requestCode: Int,
        permissions: Array<out String>,
        grantResults: IntArray
    ) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults)
        if (requestCode == REQUEST_EXTERNAL_PERMISSION_CODE && grantResults[0]==PackageManager.PERMISSION_GRANTED) {
            runUpdater()
        }
    }

runUpdater():

    private fun runUpdater(){
        val autoUpdate = AutoUpdate("url", BuildConfig.VERSION_CODE, null, null)
        autoUpdate.getUpdate(supportFragmentManager,false)
    }

for run check function and runUpdater(), call checkPermission(PERMISSIONS_EXTERNAL_STORAGE)

Modify

you can replace old dialog. For do this, you need put your dialog layout id in constructor ``` AutoUpdate("url", BuildConfig.VERSION_CODE, YOUR DIALOG'S LAYOUT ID, "response") ``

** BE CAREFUL **. Your custom dialog must include this:

1. TextView (title of update) with id - update_update_title
2. TextView (version_str) with id - update_update_version
3. LinearLayout (layout with all change log texts) with id - update_update_change_log_list
4. Button (button update) with id - update_update_update_btn
5. Button (button skip) with id - update_update_skip_btn

Explanations

the first parameter takes the URL of your server, which should return such a json-string

{
      "version_str":"NEW VERSION, DOWNLOAD NOW", # - this text will be displayed under the title of the dialog
      "version":YOUR APP WERSION (1,2,19 .etc), # - this need for check build version client and apk on server, check versionCode in Gradle
      "title":"New Update", # - title of update
      "change_log":[{"title":"Title 1","text":"title 1 text"},{"title":"Title 2","text":"title 2 text"}], # - update log. The new object in the array will be shown as a new block
      "update_link":"url to new apk" 
}

last parameter takes json key, if your server send json like this:

{"response":
  {"version_str":"123",...},
...
}

using such an example of a server response, you need to specify such parameters in the constructor AutoUpdate("url", BuildConfig.VERSION_CODE, null, "response")

if your server response only

{"version_str":"123"...}

AutoUpdate("url", BuildConfig.VERSION_CODE, null, null)
