Answer 1

PackageManager pm = getPackageManager();
try {
    ApplicationInfo ai = pInfo.getApplicationInfo("package вашего приложения", 0);
    String sourceApk = ai.publicSourceDir;
} catch (NameNotFoundException e) {
    e.printStackTrace();
}

In your case, it will most likely be easier to write in the Manifest.
I remember, back in the days of old mobile phones and J2ME, in the "Dating Galaxy" chat, referral information (the id of the person who invited the friend) was stored inside the jar in the manifest. jar, respectively, was generated on the server for each person. In Android, it seems, this is also possible.
