KeePassJava2 java.lang.NoSuchMethodError saving SimpleDatabase on Android

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)

Is this project still alive?

Mar 25 '20 07:03 lubbo

sure, why do you ask?

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

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

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

Thanks Pavel - NB it's 1.11

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Though it's a bit outdated, but still usable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?

Coming back to review, this still looks as though there are multiple JARs on the classpath and that an out of date version is being picked up - see earlier comment - I will close unless there is more discussion needed.
