The only way to find out the package that sent the Intent seems to be via Acitvity#getReferrer() (taken from this SO post). In its docs, the following is clearly stated

Return information about who launched this activity. If the launching Intent contains an Intent.EXTRA_REFERRER, that will be returned as-is; otherwise, if known, an Intent#URI_ANDROID_APP_SCHEME referrer URI containing the package name that started the Intent will be returned. This may return null if no referrer can be identified -- it is neither explicitly specified, nor is it known which application package was involved.

Hence you can add Intent.EXTRA_REFERRER to the intents you're sending to override the default value.
