Try Using WorkManager to make sure it cleans up the temp files even after the app is closed.

    override fun doWork(): Result {

            return try {
                applicationContext.cacheDir?.let {
                    if(it.exists()){
                        val entries = it.listFiles()
                        if (entries != null){
                            for (entry in entries) {
                                Timber.i("My file: ${entry.name}")
                                entry.delete()
                            }
                        }
                    }
                }
                Result.success()
            } catch (e: Exception) {
                Timber.e(e)
                Result.failure()
            }

        }
