bad apk when using bitcoinj from maven central

I just tried to switch from a local bitcoinj jar to a version pulled from maven central and face a strange problem. The resulting apk's device compatibility marking is broken.

enter image description here this section shows the change I tried:

// compile "com.google:bitcoinj:0.11.1"
// the above looks like a really good idea, but unfortunately the apk resulting from this
// is broken in the way that it is marked as available only for x86_64 - which are 0 devices
// in google play at the moment - something strange gets pulled in there 

compile files('libs/bitcoinj-0.8.jar')

before investigating what unwanted thing is pulled in here I just wanted to ask here if somebody faced the same thing. Strange only that this seems to be a jar dependency and I do not expect things like this to be pulled - there should be no native code ..

Solution

  • I digged a bit deeper. Bitcoinj pulls in libscrypt. From the bitcoinj pom:

    <dependency>
<groupId>com.lambdaworks</groupId>
<artifactId>scrypt</artifactId>
<version>1.3.3</version>
</dependency>

    and libscrypt contains native code for x86_64 only:

    $> unzip -l scrypt-1.4.0.jar | grep libsc
21708  2013-05-26 12:20   lib/x86_64/darwin/libscrypt.dylib
22140  2013-05-26 12:20   lib/x86_64/freebsd/libscrypt.so
21306  2013-05-26 12:20   lib/x86_64/linux/libscrypt.so

    this seems to cause the problem
