java.lang.NoSuchFieldError: org.apache.http.message.BasicLineFormatter.INSTANCE

Question

Buona giornata!

Ho bisogno di aiuto!

Sviluppo app per Android con integrazione IIS (SharePoint). E quando ho eseguito questo codice (codice 2), ottengo l'errore

java.lang.NoSuchFieldError: org.apache.http.message.BasicLineFormatter.INSTANCE

corro questo codice in firstActivity nel metodo onCreate (codice 1)

Versione httpclient - 4.3;

Codice 1

new Thread(new Runnable() { 
      @Override 
      public void run() { 
        new HttpsClietn(); 
    } 
}).run(); 

Codice 2

Grazie per qualsiasi aiuto.

Answer 1

Google Android viene fornito con un fork estremamente obsoleto (pre BETA 4.0) di Apache HttpClient. A causa della presenza di classi vecchie sul classpath, la versione di HttpClient non viene inizializzata correttamente a meno che tutte le classi non vengano spostate in un altro spazio dei nomi ('org.apache.http' -> 'thank.you.google.http')

Un modo per assicurarsi che la versione originale di Apache HttpClient non si sovrapponga al suo spazio dei nomi originale è il riconfezionamento con lo Maven Shade plugin, utilizzare the port sviluppato da Dirk Boye o lo official port of Apache HttpClient to Google Android.

Per rimuovere Android tutti HttpClient e httpcore dipendenze e aggiungere

compile group: 'org.apache.httpcomponents' , name: 'httpclient-android' , version: '4.3.5.1' // gradle depedencies 

nel file build.gradle
