Android Question Second apk in same package

[Zeev Goldstein]

I might be dreaming...
In pc I can add an exe file to my app package so it contains 2 or even more exe files.
This way I can pack the entire solution as I want it.
The user runs the main exe and if and when needed the main exe can run another exe.

Is it possible in Android?
Is it possible with B4A?

The second apk is completely independent but must be with the main apk in same package or in same apk so the user sees one package

Or should I wake up?

If yes - how?
2 apks?
Or what?

Tanks

Is it possible in Android?

No. There is no .exe in android.

Is it possible with B4A?

No. B4A does not create exe files. Only APK. And you can NOT install two APK with the same packagename in Android.

Thanks
Exe was to explain my idea, I know that there is no exe in Android.
The idea was to put 2 apps in same package so I don't need to install 2 app but only one that will contain the second

no such thing in android

 

[Zeev Goldstein]

Thank you
As I suspected I will have to wake up...

Any idea how to overcome such a problem?
I can create another app, upload to Google layout store etc...
But I'm trying to avoid it

 

[DonManfred]

I don´t see how you would overcome that as it is not possible in Android.
Create a second app with a new packagename and start this app if you want to.

Yes, seems like the path to go to
I wanted to avoid the need to send the user to install another app...
That's the reason for me getting 'crazy'
I want to simplify the user's life...
In pc I just pack 2 or more exe files and run them internally if and when needed
One setup

you can use Intent to install an apk file however you need to have target phone enable "install app from unknown sources" turned on

It will be easier and simpler to do it the right way through the store...

you can also use intent to open an app in play store (leaving it on the user to install it from there)

Yes, that's the idea
If I can't avoid it and I must force the user to do it, at least do it the right way

 

[Zeev Goldstein]

If I want to pass some info between my app and the second one that will be invoked as intent - how do I do it?
So the second app will get some input?

And, how if possible to return info to the calling app?

Thanks

If it is in same apk. you can get on dreaming.
Put the second apk into asset folder of your 1st app. while the 1st app running you can check the package if it is installed ? and then you may do what you want to do

If you want to create something like the B4A-Bridge, check the source code.
In B4A-Bridge, the app checks if you have B4A-Designer installed. If it is not, it will prompt you to install the designer app which has a different package name.

Create a second app with a new packagename and start this app if you want to.

Or you realize the two programs with one B4XPages in which you only initialize the necessary B4Xpages you need, based on your user's choice. Or just throw away pages you no longer need. You just have to think much more modular and realize functionality in reusable and program shareable B4XPage that you can add at will in programs you create.

An additional advantage: you can use the global variable in the B4XMainPage to exchange information between the two programs within your program without being hindered by the Android data restrictions.

By the way, storing and reading a Global variable in the B4XMainPage is a good reason to free up memory space by, for example, removing a B4XPage and a read-out or to write all variables between to program and a file.
