I want to know from where my app is installed (who installed my app).
I need to use getInstallerPackageName(). And This method need to android.permission.INSTALL_PACKAGES permission. But this permission is not grant by the system.
Returns null in all above methods.
What way do you suggest to solve the problem?
What other way do you suggest for this?
Thanks.
I wouldn't recommend using this permission: it probably will result in your app getting removed from google play store
You should be using REQUEST_INSTALL_PACKAGES. The INSTALL_PACKAGES permission is not allowed to be used by third party apps according to the documentation: https://developer.android.com/reference/android/Manifest.permission.html#INSTALL_PACKAGES

update (src):
Google Play restricts the use of high risk or sensitive permissions, including the REQUEST_INSTALL_PACKAGES permission, which allows an application to request installing packages. Apps targeting API level 26 or newer must hold this permission in order to use Intent.ACTION_INSTALL_PACKAGE or the PackageInstaller API.
