donations to open source projects

[tomholub]

I would like to make donations to open source projects that we rely on (on Android) to support their effort which we benefit from.

This could be libraries we use, other type of software, a free web service, whatever you find most useful in your work.

Total budget: $500 USD

Please help me make a list of projects that accept donations (or if they don't have any public info, you can ask them if they will accept a donation - they should give us a paypal email).

Example:
project a: $XX USD donation url: ...
library b: $XXX USD donation email: ...
library c: $XX USD donation url: ...
.. . ... .
total: 500

Thanks!

Last time I was trying to put together a list:

acra
androidx.test.espresso
com.squareup.leakcanary
com.squareup.retrofit2
Apache foundation
nodejs-mobile

But I'm sure I skipped many

The most useful libs in the project:
Retrofit - doesn't have info about donations at all. It created by a big development company (Square). I think it has enough investment
ACRA - doesn't have PayPal(but has https://flattr.com/@KevinGaudin) - 20%. I can ask about PayPal
JavaMail - https://www.eclipse.org/donate/ - 50%
bouncycastle - https://www.bouncycastle.org/donate/ - 20%
apache commons-io - https://www.apache.org/foundation/contributing.html - 10%
