Missing classes detected while running R8. Please add the missing classes or apply additional keep rules that are generated in

Question

hello guys i am currently develop android app, i have the intention to use proguard to protecting my app from reverse engineering

however, after i applied proguard to my app was an error like this :

Missing classes detected while running R8. Please add the missing classes or apply additional keep rules that are generated in mypath\app\build\outputs\mapping\debug\missing_rules.txt.

Missing class sun.security.x509.X509CertInfo (referenced from: java.lang.String org.openjsse.sun.security.ssl.SSLLogger$SSLSimpleFormatter.formatCertificate(java.security.cert.Certificate))

Missing class sun.util.logging.PlatformLogger$Level (referenced from: void org.openjsse.sun.net.www.protocol.https.HttpsClient.<init>(javax.net.ssl.SSLSocketFactory, java.net.URL, java.net.Proxy, int) and 1 other context)

Missing class sun.util.logging.PlatformLogger (referenced from: void org.openjsse.sun.net.www.protocol.https.HttpsClient.<init>(javax.net.ssl.SSLSocketFactory, java.net.URL, java.net.Proxy, int) and 1 other context)

i have try to set up the missing_rules to fix this problem, but it didn't work at all can you guys help me to find the solution of this problem ?

here is my code :

Answer 1

I got the same problem when i set minifyEnabled value to true.

        release {
        debuggable false
        minifyEnabled true // change it
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
    }

hope it will solve your problem

i intended to make it true for using the proguard, but thanks for answering ;), i've also solved the problem months ago – Briney

@Dzy, do you care to mention how you solved it? This is what StackOverflow is here for. – Schizogony

sure, you can visit this link : issuetracker.google.com/issues/330437902 if you still have a problem, you can try to ask to issuetracker, it's worth to try – Briney
