Question

I am trying to make use of spongycastle and followed all the help I could get to include it but when the application execute it crashes at the code where I add it as a provider:

static {
    Security.addProvider(new org.spongycastle.jce.provider.BouncyCastleProvider());
}

I add scprov-jdk15-1.46.99.3-UNOFFICIAL-ROBERTO-RELEASE.jar as an external JAR to my project and eclipse does not report any errors.

Any ideas?

The stacktrace:

Was it helpful?

Solution

The NoClassDefFoundError thrown here suggests that the SpongyCastle classes are not being included in your deployed apk file - try unzipping the apk to check this). This could be caused by a few things, make sure you do a clean build (are you builiding with ant or eclipse?) and if the problem persists, it's likely a proguard issue - ProGuard may be stripping out classes it thinks are unused - could you post your proguard.cfg?
