应用内更新（即时）不重启应用

Question

Facing an issue with IMMEDIATE app update mode. After successful completion of app update, everything is closed and not restarting the app. That is the issue. But android documentation says:

A full screen user experience that requires the user to update and restart the app in order to continue using the app. This UX is best for cases where an update is critical for continued use of the app. After a user accepts an immediate update, Google Play handles the update installation and app restart.

code

class MainActivity : AppCompatActivity() {

    companion object {
        const val UPDATE_REQUEST_CODE = 112
        const val TAG = "MainActivity"
    }

    private var appUpdateManager: AppUpdateManager? = null

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        findViewById<TextView>(R.id.tv_text).text = "Version " + BuildConfig.VERSION_NAME

        // Returns an intent object that you use to check for an update.
        appUpdateManager = AppUpdateManagerFactory.create(this)
    }

    private val listener: InstallStateUpdatedListener =
        InstallStateUpdatedListener { installState ->
            if (installState.installStatus() == InstallStatus.DOWNLOADED) {
                // After the update is downloaded, show a notification
                // and request user confirmation to restart the app.
                Log.d(TAG, "An update has been downloaded")
            } else if (installState.installStatus() == InstallStatus.INSTALLED) {
                Log.d(TAG, "An update has been installed")

    private fun checkAppVersionNew() {

        appUpdateInfoTask.addOnSuccessListener { result: AppUpdateInfo ->
            if (result.updateAvailability() == UpdateAvailability.UPDATE_AVAILABLE && result.isUpdateTypeAllowed(

Answer 1

I faced this issue and after 2 days I added

android:launchMode="singleTask"

to the launcher Activity And I used

ProcessPhoenix.triggerRebirth(this)

From ProcessPhoenix library And then the app restarted after updating.
