java.lang.NoSuchMethodError saving SimpleDatabase on Android

[lubbo]

When I save the SimpleDatabase

        val basePath = ContextWrapper(context).filesDir
        val credentials = KdbxCreds(credentials.toByteArray())
        val db = secureDatabase ?: return
        FileOutputStream("$basePath${File.separator}$database.kdbx").use { outputStream ->
            db.save(credentials, outputStream)
        }

I get this error:

java.lang.NoSuchMethodError: No static method encodeBase64String([B)Ljava/lang/String; in class Lorg/apache/commons/codec/binary/Base64; or its super classes (declaration of 'org.apache.commons.codec.binary.Base64' appears in /system/framework/org.apache.http.legacy.boot.jar)

any suggestion?

Is this project still alive?

[jorabin]

sure, why do you ask?

[jorabin]

You are picking up Base64 from /system/framework/org.apache.http.legacy.boot.jar rather than commons-codec.1.11.jar - you'll need to find a way to exclude the first from your classpath

[ivanovpv]

Please include in your build.gradle following reference to base64 support:

implementation group: 'commons-codec', name: 'commons-codec', version:'1.10'

[jorabin]

Thanks Pavel - NB it's 1.11

[ivanovpv]

Workable example for Android is here

Though it's a bit outdated, but still usable

I haven't see commits since 2018 ... sorry.

I tried but the error persists ... trying resetting AndroidStudio cache... Nope. It doesn't work.

I'm not able to open it in AndroidStudio ... Have you used Eclipse?

[jorabin]

Coming back to review, this still looks as though there are multiple JARs on the classpath and that an out of date version is being picked up - see earlier comment - I will close unless there is more discussion needed.

[jorabin]

closing as no longer a live issue
