ProBundle price ?

I'm going to make an official announcement in the week to come about my new chargeable product: ProBundle (Pro for Professional and Protection). I'd like to know if you consider that 30 euros is a fair price for the content (in the attached archive, you will find the documentation of some libraries):

- ArchiverPlusZip v1.0
Based on the Zip4j library, this library allows to add, extract, update and remove files from a zip archive.
It supports encryption and decryption (standard and AES), Zip64 format and split zip archives.

- CallSubExtended v2.0
This library allows to run a sub in a different thread with AsyncCallSub and perform a CallSub with any number of parameters with CallSubX or AsyncCallSubX.

- DataCollection v1.03
This library wraps the ArrayDeque, BitSet, PriorityQueue, SparseArray, Stack, TreeMap and TreeSet classes.
These classes can replace your lists, maps or arrays for specific tasks. A TreeSet, for example, can maintain a sorted list of objects in a more efficient manner than a typical List class. A TreeMap is a map whose entries are sorted by their keys. A SparseArray is also a sorted map, but restricted to integer keys, that is lightning-fast.

- Error Detection + source v1.0
This library converts the OutOfMemoryError and StackOverflowError to RuntimeExceptions for a given sub, allowing to catch them. For experts only.

- F5Steg v1.0
This library implements F5, a secure steganographic algorithm, which embeds data into images. Data are encrypted with the application signature, so any tampering of the APK prevents from extracting valid data.

- Guide "Protect My App"
This PDF guide gives a brief explanation of how hackers can decompile your application and change your code, then it explains the things to avoid and how you can enforce the protection of your code.
A solution is given to secure your assets (images, db, etc.), passwords, and even pieces of critical code.

- FastIO + source v0.8
This library replaces the Read and Write functions (with their encrypted variant) of the RandomAccessFile library for arrays of bytes. These new functions are a lot faster.

- PackageUtils v2.0
This library replaces the PackageManager class of the Phone library. It gives plenty of informations on packages (activities, features, permissions, receivers, services, etc.) and can list the features available on the system (camera, gps, wifi, etc.). It allows experts to change the enabled state of components.
An application is provided with the library to show what you can get with it.

- Free bonus for the first 100 donors:
CoverFlow v1.31
This view is similar to the free Coverflow library available in the B4A forum but it uses a different approach (the same as UltimateListView) to load images.

- Planned (free for donors when available):
ArchiverPlus7z
ArchiverPlusRar

Hi @Informatix.

Your works are always excellent.

I consider the price too high, if compared with the price of B4A and some people might want to use only certain parts of the library.

I can imagine that behind this there is a lot of work (as well as knowledge and skills), of course.

I think that 20€ is the right price.


Good luck


[EDIT] b4a price is not a "fixed price", then the comparison does not make sense.
I would publish each library separately, with prices ranging between 5€ and 10€ (the possible total would be over 30€ )

May I ask if they are for B4J too? At least archiver, callsubextended and the guide...

hi fred, i think 30 euro is fair enough, only that i dont know if those libs will be useful for me at least. look like they are more for expert...
can you put some game libs in this bundle like SB Pro and others...

Sounds reasonable to me. I'm not sure that I'll have need of it but at approx £20 its a lot of added functionality and like Erel had already said, I'm sure it will be of a very high standard.

<- want to be one of the first hundret ; As already written by @RandomCoder i´m sure the libraries will be of high quality.
Additionally i´m interested in the F5Steg and the new archiver. I will donate for the probundle when the link to donate is available.

I bought your UltimateListView and it's a great-huge lib. I will buy your new ProBundle for sure. Please release it soon.

I think that 50 to 70 % of the current Ultimate Listview users will buy your new Probundle; i for sure.

[...]

I won't split it because:
- some libraries of this bundle are involved in the solution that I give in the "Protect My App" guide to secure your assets and code;
- you can get CallSubExtended (in an old but working version) and DataCollection by donating for ULV;
- I don't think that people will donate much for the other libraries of this bundle.

I think that 20€ is the right price.
I could start at 20 euros to know whether people are ready to donate but, at this price, I won't add ArchiverPlus7z and ArchiverPlusRar.

The ArchiverPlusZip library and the PDF Guide about protection are not at all for experts. Who's not concerned by the protection of his/her app?

It seems to me that games libs are a bit off-topic in this bundle. But I can create another bundle for games. I have already done CameraForLibGDX and VisionForLibGDX; VideoForLibGDX should follow, but honestly I don't know whether these libraries will be released because the code is experimental and very dirty.

SB Pro? I have no idea of what it is.

I hope so !
You just got a 30,- Euro donation from me... I hope it fit your price for the probundle incl. ArchiverPlusZip (and hopefully ArchiverPlusRar in the future). If you decide to set an higher price for the lib then please tell me and i will do an aditional donation.
