There is one library, the use of which is free of charge, provided that the application is not loaded into google play.

There was a question: can google play show something to me?

The same will have to dig in the code of the obfuscated APK to roll out a lawsuit.

Or you can safely use and save $ 3000 without fear of falling under the ban?

PS: Everything is legal - the source code of the library is open and licensed under the GNU GENERAL PUBLIC LICENSE, what are you minusing? Despite the GPL, the authors for some reason prohibit the use of commercial products and sell it as a .jar file.

Of course, the bonus is 24/7 support, but why then the ban is not clear.

If the source code of the application in which it is used under GPL v3 is open, then there is no problem.

    This question should be closed, because the legal issues are not related to the resource. - Eugene Krivenja

    @EugeneKrivenja; People here share experiences, not tediousness! Just to close something, but to prohibit. - Evgeniy

    Rather, even Google Play itself will not produce anything, but the author of the library may very well, and DMCA takedown in GP may be one of the means of influence, as a result of which the application will disappear from the store, and it will not be easy to return it back. - D-side

    @Evgeniy, cool experience: I will steal $ 3k, will they catch me? :-D Have you ever bothered to ask a neutral question and technically. - Eugene Krivenja

It's not just a bath. You can be sued and sued significantly more than the cost of use, depending on the contract. In fact, when using proprietary libraries, you agree to this agreement and it will not be difficult for rightholders to confirm this fact of its violation in court.

Such companies that develop libraries with their sale for $ 3000, it seems to me that several specialists in reverse engineering can afford to find out if this library is used in your code.

A completely different question is how things will be in general, the actions of companies on this score are unpredictable, on the one hand it’s not a fact that your application will become so popular that the right holders of the library will research it, but what the hell is not joking is possible that even it will not become popular, you can be sued.

  • The best answer! The license is there GNU GENERAL PUBLIC LICENSE, the source code is open. At the same time prohibit to fill in the application with their application in the market. Very strange. - Evgeniy

    But this is an interesting amendment, according to the GPL, you can set a fee for using the library, but you can’t oblige users to pay for its use, and it should be borne in mind that most likely some or all of your program must also comply with the GPL. But these questions are already too difficult, garbage is determined by eye, in each case it is necessary to understand separately. - Komdosh
  • Yes, with this license everything is not easy: you can open the application code that uses this or under GPL V3 and there will be no problems. At the same time, opening a part of the code will inevitably require opening the rest of the code that uses this :) - Evgeniy
  • Yes, that is right. - Komdosh
