Errore Proguard durante la generazione dell'APK con firma protetta

Question

Ho provato negli ultimi 2 giorni a generare l'apk firmato sicuro per la mia applicazione, ma non ho ancora ottenuto alcun risultato.

Ho controllato tante risposte di StackOverflow e ho provato ogni soluzione, ma per me non ha funzionato. Quindi eccomi qui se qualcuno mi può aiutare, sarà davvero grato e apprezzerà davvero l'aiuto.

Di seguito è riportato l'errore che sto ricevendo durante la generazione dell'apk firmato sicuro.

Modificato:

Ho alcuni cambiamenti nel mio file Proguard ed ora sto ottenendo sotto l'errore

Proguard returned with error code 1. See console 
Note: there were 209 duplicate class definitions. 
You should check if you need to specify additional program jars.

Per favore aiutatemi ogni aiuto sarà apprezzato.

Answer 1

Ho risolto il problema aggiungendo le due righe seguenti nel mio file proguard.cfg.

-keep class android.support.v4. ** {; }
-dontwarn android.support.v4. *

Answer 2

uso

-dontwarn android.support.v4.** 

un altro tentativo:

scaricare il Proguard tardive (ho scaricato 4.9) e cambia la cartella lib

un altro un altro tentativo:

voi può usare un proguard standard. per esempio vedi here

Recentemente ho anche affrontato diversi problemi e progettando di apprendere in profondità il meccanismo progruard. Ma al momento non ne ho idea. Ma la precedente soluzione tre mi ha salvato più volte
