Draft: Newapp: Cwtch

• The app complies with the inclusion criteria
• The original app author has been notified (and does not oppose the inclusion): https://git.openprivacy.ca/cwtch.im/cwtch-ui/issues/141
• All related fdroiddata and RFP issues have been referenced in this merge request
• The upstream app source code repo contains the app metadata (summary/description/images/changelog/etc) in a Fastlane or Triple-T folder structure
• Builds with fdroid build
• Releases are tagged

---

Why draft? Waiting for upstream 1.9.0

Prebuild lines:

• tor-android builds a "sampleapp" by default which we don't need.
• bump build.tools.gradle to 4.0.1 else it fails with No toolchains found in the NDK toolchains folder for ABI with prefix: arm-linux-androideabi
• bump Java to 11 else it fails with unrecognized Attribute name MODULE (class com.sun.tools.javac.util.UnsharedNameTable$NameImpl
• And a lint ignore for:

/home/vagrant/build/im.cwtch.flwtch/android/app/src/main/res/layout/splash_view.xml:7: Error: LottieAnimationView must extend android.view.View [Instantiatable]
    <com.airbnb.lottie.LottieAnimationView
    ^

   Explanation for issues of type "Instantiatable":
   Activities, services, broadcast receivers etc. registered in the manifest
   file (or for custom views, in a layout file) must be "instantiatable" by
   the system, which means that the class must be public, it must have an
   empty public constructor, and if it's an inner class, it must be a static
   inner class.

1 errors, 0 warnings

What's still odd:

• I had to go get some of the libcwtch deps manually else it will fail to download some of them (see log above for info)

• set goproxy for privacy reasons, no need to inform Google we're building something
• used ndk 21e instead of libcwtch readme 22b else libtor fails: https://github.com/guardianproject/tor-android/blob/0.4.6.9/external/Makefile#L29
• bypassing libcwtch make android and running directly since $(shell ...) would fail
• upstream apk in x86 libs has only libgojni.so, in my build I (as expected?) added libtor.so too
• upstream apk in x86_64 has the other 3 libs, but not libtor.so, in my build I (as expected?) added libtor.so too
• are x86* arches not supported?
