    No problem Ruthie, there are a lot of thing more urgent

    Yes of course. It is never obvious to work on someone else code so I would be happy if we could help each other 🙂

    Hi Ladies and Gents,

    I forked Hanks feathercoinj and patched it to report protocol version 60005 now.
    Send Hank a pull request to merge my patch.

    I also got an android developement environment set up on my pc and managed it to compile a new feathercoin-wallet apk for andriod. My tablet is syncing again 🙂 .

    Of course I have to wait until the snc has completed to be sure that it works well.

    I also figured out, that it connects to ‘normal’ clients and it seems, that the android wallet does not need a backend server.

    I have no idea jet how to get this one into google playstore, so if someone wants the apk, send me an IM so I can send you the apk file or suggest how/where I can upload the android package.

    Update:

    My Android wallet is fully synced now 🙂


  • | Tip Ilocans

    You need an android developper licence (I don’t remeber the exact name). It cost 25$.

    Then you will be able to publish the apk of the application. There are a lot of tutorial if you search on google. The process can be different regarding if you are using eclipse, ADT,…

    Thanks for the info 🙂

    I will consider a developer account, if I will develop own applications.

    I think I will not push the android wallet to the playstore, as it is written by somebody else and I just changed two lines in the source code.

    I created a pull request on Github, and I hope, that they will update the playstore, too.

    My offer to send the apk was meant just as a temporary solution until playstore has the new version available.


  • | Tip Ilocans

    Can you explain how you make it work ? I mean how did you make it compile ?

    It seems that it need dependencies but I don’t achieve to compile anything. I guess I am missing something but I don,t find what it is…

    Thanks

    I think that is brilliant work getting the mobile wallet fixed, even if it is a couple of lines, Wellenreiter. However, the mobile wallet is an open source project, I believe other coins have forked the code.

    I would suggest Peter puts a “side loader” web download on the Feathercoin download site till the App is updated in App store. Again other coins have done that.

    Having a mobile working mobile application is essential, it would be more secure if we did our own basic version with the wallet. It could be made available in F-Droid.

    kstenson for finding the bug.

    I have been running the wallet the last couple of days with an update version number, but I haven’t tested out any functions to see if there are any breaking changes between protocol versions. I need to get some time to go though the updates since the last release Hank did.

    For people that want to build the source, if you grab the feathercoin wallet app, you also need to download and build the feathercoinj code here:

    https://github.com/hank/feathercoinj

    and follow the instructions for building. Once you’ve got that installed with maven your be able to build the wallet app.

    To change the version number you need to make the change to this file in feathercoinj project:

    https://github.com/hank/feathercoinj/blob/master/core/src/main/java/com/google/feathercoin/core/NetworkParameters.java#L43

    Keith, or for me who really doesn’t have time to work out how to do all of that, but really needs the wallet app to test something else I’m working on. Is there an option where you can send me the app, I can up load it to my phone and test both it and my new project and report on the results?

    Hello,

    I tried to build feathercoinj but when i execute maven clean package, I have errors such as:

    [ERROR] /C:/feathercoin/feathercoinj/core/src/test/java/com/google/feathercoin/core/BlockChainTest.java:[159,43] cannot find symbol

    [ERROR] symbol: variable interval

    [ERROR] location: variable unitTestParams of type com.google.feathercoin.core.NetworkParameters

    And the code athe the line 159 is : for (int i = 0; i < unitTestParams.interval - 1; i++) {

    It does not like the “.”

    I am fighting against this. I guess I missed something. Did you get this error message ?

    Thanks,


  • Moderators | Tip Wellenreiter

    There is a missing variable definition in the code. I defined the variable, but got more errors in the test area.

    If you locate my fork on github and use it, it will compile, but you need to run mvn with -DskipTests, as the test area has tons of errors.

    It seems, that the tests have not been adapted for a long time.

    My username on github is wellenreiter01, so the fork’s name should be wellenreiter01/feathercoin-wallet

    Hi

    This is the unit tests in hanks code that are broken, to get around this you need to tell maven to skip the tests. so the command would be ‘mvn clean install -D maven.test.skip=true’

    This build the package succesfully for you.

    Keith


  • | Tip Ilocans

    Thanks it worked. I don’t know maven so I am a little bit lost.

    Once I did this I tried to compile the wallet with ‘mvn clean install -D maven.test.skip=true’ but it does not work because it needs feathercoinj-0.95-SNAPSHOT.jar

    After serveral attempts I solved this error by putting the file in the m2 repository in a folder I had to create repository\com\google\feathercoinj\0.95-SNAPSHOT

    Does it have to be done manually or is there another way ?

    Even if a put the file there I still have errors:

    [ERROR] Failed to execute goal com.jayway.maven.plugins.android.generation2:android-maven-plugin:3.5.1:generate-sources (default-generate-sources) on project wa

    llet: Execution default-generate-sources of goal com.jayway.maven.plugins.android.generation2:android-maven-plugin:3.5.1:generate-sources failed: A required class was missing while executing com.jayway.maven.plugins.android.generation2:android-maven-plugin:3.5.1:generate-sources: Lorg/sonatype/aether/RepositorySystem;

    Did you get this error too ?

    Thanks for your help


  • Moderators | Tip Wellenreiter

    I didn’t have these problems

    What I did:

    1. clone feathercoinj from github to a clean directory
    2. compile feathercoinj: ‘mvn clean install -DskipTests’ (yes, no space after the -D 😉 )
    3. clone feathercoin-wallet from github
    4. compile feathercoin-wallet:
    • cd to feathercoin-wallet dir
    • cd to subdir ‘wallet’
    • mvn clean install

    This did the job for me, but signing the apk file failed, because jarsigner was asking for an alias.

    I signed the apk manually:

    1. Create a keystore file with ‘keytool’ and define an alias, e.g. feathercoin-wallet
    2. copy the jarsigner call from the error message provides by the MVN output, starting with jarsigner and skipping the stuff in the beginning of the line.

    Done 😎


  • | Tip Ilocans

    Hi,

    You method does not work for me at all 😞

    If I use the ‘mvn clean install -DskipTests’, it does not skip the tests and I have the ‘cannot fin symbol’ error for feathercoinj

    And I have the same error for the feathercoin wallet.

    I am not really lucky

    Thanks for the help, maybe someone has a better idea ?


  • | Tip Ilocans

    Ok I finally find solutions.

    • First use It seems I have error with maven 3.1+ but not maven 3.0.5

    • Also I had an error it does not find aapt.exe

    To solve this, I had to execute:

    cd %ANDROID_HOME%/platform-tools
    mklink /H aidl.exe …\build-tools\19.0.0\aidl.exe
    mklink /H aapt.exe …\build-tools\19.0.0\aapt.exe

    • I had also an error with dx.jar. The solution is to search the file in the sdk subdirectory and copy it in %ANDROID_HOME%/platform-tools

    I am stuck at the final setp, signing the file beacause jarsigner ask for an alias. Wellenreiter coud you be more explicit please ?

    I use eclipse to create a keystore file with a password, an alias (feathercoin-wallet) and a password for the alias

    But I don’t understand where I have to put it. First I thought it was in …\m2\repository\org\apache\maven\plugins\maven-jarsigner-plugin\1.3.1

    but it does not work

    Thanks for the help


  • Moderators | Tip Wellenreiter

    Ok, so your problems where related to the setup of the sdk environment for Android. 😉

    The alias for jarsigner is the same you specified when creating the keystore.

    So in your case the call to jarsigner should look like

    ‘jarsigner -verbose -sigalg MD5withRSA -digestalg SHA1 ~/workspace/feathercoin-wallet/wallet/target/wallet-1.098.apk feathercoin-wallet’

    Adapt the path to the .apk file to match your system.

    In Linux the default keystore is the file .keystore in your home directory.

    If you defined another keystore file in eclipse, you must tell jarsigner the name of the file as a command parameter.

    regards

    Wellenreiter

    use jarsigner --help to get the right option.


  • | Tip Ilocans

    Most of my problems was due to maven. It seems the project is not supported by maven 3.1.1 or maven 3.1.2

    I was not able to find in the settings of the project where the keystore location is configured. There are variables for the keystore but I did not found where they are initialized.I tried to put the file in the home directoryin windows (C:\users\username\) but it didn’t work. So I sign manually the file.

    I try to understand how the whole thing work and I understood that the wallet as 2 parts:

    • feathercoinj that is a Java implementation of the feathercoin protocol, which allows it to maintain a wallet and send/receive transactions

    • feathercoin-wallet that is more the front end

    I was wondering when the feathercoin protocole will update to 0.86, does anyone will also improve feathercoinj ?

    My other interrogation: does the wallet need to download the whole blockchain and store it on the phone like the desktop version?

    Thanks


  • Moderators | Tip Wellenreiter

    Answer to your first question: yes, feathercoinj will be updated by Bushstar and myself

    For your second question I need to check.

    Also, the Andriod target for the wallet is type 14, which is a tablet, so l’m not sure, if phones are supported with the current version.

    Did you check, if playstore provides the wallet, when accessing it from a phone?


  • | Tip Ilocans

    API level 14 Is just a version of android (Android 4.0). In my opinion, it is a little bit high as min API level because almost 25% of android users still have Android 3.2 or less

    But I think the reason is actionbarsherlock needs this API.

    Anyway, It works on phone in installed it on Samsung Galaxy SIII.
