Bitcoinj will not compile onto Nexus 5 with Android Studio

Question

I am building an app using Bitcoinj and I am trying to run it on a Nexus 5. When using grade to build Bitcoinj - compile \'org.bitcoinj:bitcoinj-core:0.12\' - and subsequent

Answer 1

When trying to run an android app that uses the BitcoinJ library for Nexus 5, with the latest android version 5.0 (Lollipop) you will get this error message "INSTALL_FAILED_NO_MATCHING_ABIS". The main reason is that you are trying to install an app that has native libraries and it doesn't have a native library for your cpu architecture.

The native library that did the problem was Scrypt.jar so I excluded it

    compile('com.google:bitcoinj:0.11.3') {
    exclude module: 'scrypt'
}

and instead of using

com.lambdaworks.crypto.SCrypt;

just use another scrypting library for instance,

org.spongycastle.crypto.generators.SCrypt;

Good Luck
