Is it legal to decompile an apk and use part of it's code? (more specifically: a URL connector (I haven't learned that yet)).
The rest of the app (layouts and such) is made by me. Can I publish this app without being concerned on the legal front?
回答1:
Decompiling is absolutely LEGAL, regardless of what the shills say. At most, you can be sued for unauthorized activity relating to software unless you're redistributing it. Courts in the U.S. have always upheld the right of users to know exactly what code is being installed on their systems by programs they have legitimately obtained.
People REALLY need to quit saying "ILLEGAL" unless they know what they're talking about. There is absolutely NO law in the U.S. that states you cannot copy for private purposes or decompile software. Companies have tried to sue to stop it, but; a) that's only civil, not criminal, and therefore not ILLEGAL; and b) they've only won when the content was given to an outside party from whom the companies did not receive payment. IE the person has been shown to break the law.
回答2:
It depends on the application license but in general, if decompilation is necessary that means that the author does not allow the use of its code.
回答3:
If you want to know in simple words"It absolutely LEGAL decompiling apks,but it is ILLEGAL to use that code in making something identical to the original one".
You can learn from the code but who can't copy there work..(It sometimes depends on publishers Copyrights).
回答4:
Decompiling is both illegal and wrong, unless it's your own work.
You can learn what you need on Google, or find open-source stuff using it and learn from that.
It's illegal to decompile ANYTHING without permission.
