Building the “old” android mobile feathercoin-wallet-2
feathercoinj - build staus : SUCCESSFULLY built
I got further last night - using the maven build or Ubuntu 16.10, I was able to compile feathercoinj – SNAPSHOT/feathercoinj-tools-0.97-SNAPSHOT.pomfeathercoin-wallet-2 - build status : FAILED
feathercoin-wallet-2 build crashed looking for The POM for com.google:feathercoinj:jar:0.98-SNAPSHOT is missingBuild status :
Awaiting advice on the Feathercoin jar version mismatch / further research on POM adjustments or other way forward, push fix.Feathercoin-wallet-2 - How to build
For comparison / research to fork the latest mobile wallet, these are the “old” maven instructions to build the android wallet. The new wallet will use the “gradle” build system.
Build feathercoinj
Open a Terminal
sudo apt install maven
git clone https://github.com/wellenreiter01/feathercoinj
cd feathercoinj
git checkout v0.99
cd wallet
mvn clean install -DskipTestsBuild feathercoin-wallet-2
Open a Terminal
git clone https://github.com/wellenreiter01/feathercoin-wallet-2
cd feathercoin-wallet-2
mvn clean install -
I need to check, what I have changed in feathercoinj-0.98-SNAPSHOT
could take a day or two…
quite busy at the moment ;)

@Wellenreiter looks like feathercoinj master was set to v0.97 ,
Build Feathercoinj
git clone https://github.com/wellenreiter01/feathercoinj
compile feathercoinj
‘mvn clean install -DskipTests’ (No space after the -D )`I’m just trying git checkout v0.98 now on feathercoinj - see if that compiles :

You’re working with some old NeoScrypt code base of 2015 or so. I suggest to update first.

Cheers @ghostlander
Feathercoin-wallet-2 ~~Build now works~~
I have cloned your new neoscrypt from here:
git clone https://github.com/ghostlander/NeoScrypt.gitThen :
Copied the neoscrypt.c and .hinto : /feathercoinj/core/jni/ ,
and recompile feathercoinj

Further work
Push 3 commits need to get this far.I’ll continue to look at what went wrong (error and warning messages) with the maven build for feathercoin-walet-2
feathercoin-wallet v5 build environment
Move on to getting the bitcoin-wallet android wallt to compile - ready to start looking at the best way to reintroduce the needed litecoin / feathercoin specific settings.Litecoin wallet status
I note the Litecoin-wallet is also stuck at version 3 - so it would be interesting / good to try and form some collaboration / brance that does both? or could be pushed upstream, to build either, bitcoinj, litecoinj or feathercoinj … -
feathercoin-wallet-2 build environment, Fixing / research on
Research / experiment with Homebrew to install old version of Maven
**Build status : failed
The feathercoinj does compile and appears to be installed in maven2 correctly.
feathercoin-wallet-2 won’t compile, with the instructions provided. A couple of additional instructions / settings have helped, or may be necessary, have been identified.
Possible cause needs specific maven version to build
Information so far shows a change in the development environment, like the version of the build system Maven, is a likely area to cause the problem.

Importing the feathercoin wallet 2 a maven build into gradle to make it an android-studio project
The feathercoin-wallet-2 android wallet won’t compile. The most efficiency way forward is to fork the latest android wallet code and re add FTC specific settings.
However, on going development and knowledge of other potential fixes that can be applied to the mobile wallet, make it expedient to try to compile the old version.
Although, compiling the old wallet (v2) in a later (v5) environment has been shown to be very complicated. That experience is useful, when trying to duplicate undocumented one off work.
https://developer.android.com/studio/intro/migrate.html
Are these the correct settings?
When the wallet is imported or the new wallet forked, there are some default settings :Phone / Tablet
Minimum SDK (15) : Android 4.0.3 Ice cream sandwich Was 14 was old setting?Do we need to release different versions for TVs smart boxes etc very popular?
Wear : SDK (21)
TV : (21)
Auto : (21)
Glass : (gdk 19) -
Development of Feathercoin Mobile Wallet.

@wrapper said in [Dev] feathercoin-wallet - Version 5 Development - Mobile / Android wallet:
@Wellenreiter has fixed the compile issue with the mobile wallet and updated the current wallet to be compatible with 0.6.0 wallet.
To be clear, the actual Android app is the feathercoin-wallet-2 which uses feathercoinj as a library/dependency.
The gradle settiings I implemented for feathercoinj need to be transfered/adapted to the feathercoin-wallet-2 -
I managed to compile the feathercoinj with the gradle command :
cd feathercoinj
gradle clean :native-scrypt:copy test buildI was then able to run gradle init on feathercoin-wallet-2
gradle initThat seems to be the first step in updating to gradle. Maven compiled to a common directory where feathercoinj was available.
note: The Thread how to was followed to install dependancies.
Most of the notes are irrelevant (failed ways forward / info), especially with the the less work on the old version as possible, but looking back over, the neoscrypt update may be use-able.note: not assuming this actually built.

Further to Privacy policy (Link) for mobile wallet and Forum guidelines / policy.
The mobile wallet needs to point to a privacy statement. Whilst a clone, or even the original Bitcoin Mobile privacy policy is what the (Feathercoin) app does. It has got to be our policy to follow the (paid for) advice Bitcoin wallet uses …
We may wish to update a more full Forum policy. this seems a succinct version or FTC guidelines.
I note this project has a very good, and resonably generic policy statement :
https://hackforums.net/misc.php?action=help&hid=12
Also, slightly related, they had a good joining statement, we could do that and add a line about saying hello in New Members as your first post …
