android: support for ARMv7a and Android 8+ (#2038 )

* add armv7a * disable armv6l, that is lacking SMP atomics * Add Android 8 setting (API Ver 26) * Drop x86_64-linux, this makes no sense with `pkgs' = androidPkgs`. * Drop mis-labled x86_64-linux:lib:support (it was aarch64-android) * Drop x86_64-android, these do not exist in nixpkgs The ones set up were aarch64-android anyway (pkgs' = androidPkgs) * android: support Android 8+, armeabi-v7a (32 bit) (#2012) * test * stubs for allowing to launch the app * more stubs and minSdk lowered to 26 * replaced functions that supported on higher API levels with other functions * animated images on lower API levels and write permission * updated abi filter and scripts for downloading libs * changed compression script for multiple apks * cmake changes --------- Co-authored-by: Avently <7953703+avently@users.noreply.github.com> * update haskell.nix ref * bump hackage * bump haskell.nix (again) * build-android: add armv7 * flake.nix: remove local nixconf This change to flake.nix breaks build-android.sh script by forcing user to input y/n. AFAIK, this cannot be automated and I rather not include workarounds like piping "yes n | nix build ...". * build-android.sh: update nix version * flake.{nix,lock}: testing * flake.{nix,lock}: restore to original * update android/prepare script to use zip archives * update gradle file * android: 4.6-beta.0 (104) * android: abi filter for bundle (#2075) * android: abi filter for bundle * removed log --------- Co-authored-by: Evgeny Poberezkin <2769109+epoberezkin@users.noreply.github.com> --------- Co-authored-by: Moritz Angermann <moritz.angermann@gmail.com> Co-authored-by: Avently <7953703+avently@users.noreply.github.com> Co-authored-by: shum <shum@liber.li>

+You can join either by opening these links in the app or by opening them in a desktop browser and scanning the QR code.
+
+## Make a private connection
+
+You need to share a link with your friend or scan a QR code from their phone, in person or during a video call, to make a connection and start messaging.
+
+The channel through which you share the link does not have to be secure - it is enough that you can confirm who sent you the message and that your SimpleX connection is established.
