Improve "Credits" activity

[0xf104a]

Credits activity currently very simple and so do not have enough information as well as being inconvinient for user. So following changes should be introduced:

• [x] Add arrow for navigating back to SettingsActivity(just like SettingActivity have exit arrow)
• [x] Add description for each contributor/component(e.g. component, contribution, license, etc.)
• [ ] Separate lists for libraries and authors of commits/resource/etc.(won't implement since it is not user-friendly)

Hello, I want to contribute to this issue as a beginner but I am unable to find the credits activity. Can anyone please help me by telling me that where it is present

Hello. Sorry for this: I just forgot to rename it since it was initially designed for only putting licenses, but now I think there should be all people who contributed to this project. So I have just renamed it in last commit :) Now you can find it by path app/src/main/java/com/polar/nextcloudservices/CreditsActivity.java

Hello, I have opened the app using android studio. But I am getting an error "Cannot access com.polar.nextcloudservices.NextcloudAbstractAPI" And even after rebuilding it again and again the issue is not solving. Please help me. I have attached the screenshots for the same

Since build is succesful(as I can see from last screenshot) it seem to be problem with an Android Studio cache. So I guess doing gradle sync would help, but if it doesn't you can try to do what Stackoverflow is suggested:

Hi, I have created a pull request after solving the first two issues of this issue #17. Please have a look over it. Also please write the last issue of issue #17 in detail please, actually I am unable to understand what to do in the 3rd issue.

The third issue was mostly about that I have not imagined way to properly place license name for everyone(so what I've imagined is two lists(inside one activity or even having separate activities),but it is not user-friendly). In fact your implementation solves this problem, because we can use \n in strings, e.g.

<item>Contribution: NumberPickerPreference\nLicense: LGPL-3.0</item>

This would place a "License:..." text under "Contribution:..." line for those people whose contribution has license. So since everything is implemented I'm closing this issue. Thank you once more for your contribution!

Thanks for the compliment. This was my first contribution to open source, and I am glad that my work was helpful to you.
