Installing an external C++ program in Android
I was looking for an answer whether Google allows to install externall C++ applications together with Android Apps on Google Play. I found some information on this site: Developer Policy Center - Malicious Behavior.
They say, that the following sentence is explicitly prohibited:
Apps that install other apps on a device without the user's prior consent.
Now my question is, what exactly does mean other apps? It is about other apps in Google play or any apps like my external C++ program that I want to execute in Android app? Does I have to inform users that some C++ app will be installed in the device?

first i you want to execute an c/c++ application in android , the only right and best way is to convert that app to a static or shared library using android NDK and after that you can use it by Java Native Interface (JNI).
second , "other apps" in the sentence that you mentioned in your question , some application can install some applications in system without user permission. for example in a rooted device we can simply install application without showing any windows or getting permission. in android old release because of some security issue in non-root device we was able to install an application without asking permission.
see this link for more information :
https://paulononaka.wordpress.com/2011/07/02/how-to-install-a-application-in-background-on-android/
Update
google wont allow developers to do that because android system cannot track this executive and it could be virus or dangerous tool that may harm android system

Thanks for your response. So compiling the C++ with NDK into executable instead of library is not an option? The reason I need in to be executable is that I want to use the executable as a root user. With library I suppose I'm not able to do that.

Yes I know it, but the main question is, does Google allow it? My account has already 2 suspension, I can not allow any more ;)

google won't allow developer to do that because in android system , executive files could be a virus or harm the system because in android architecture in root-mode , you will skip the art or dalvik rules and it will have access to some files in data directory and will be able to manipulate some of the main files.
