java.lang.ClassNotFoundException in dalvik.system.BaseDexClassLoader.findClass

Question

Questo errore mi sta facendo impazzire. La mia app si blocca all'avvio quando scaricato da Google Play Store con l'errore:

java.lang.ClassNotFoundException 
in dalvik.system.BaseDexClassLoader.findClass 

mia app non va in crash quando costruire da Eclipse sulle nostre due dispositivi. Tuttavia un mese fa un cliente usava il suo telefono per costruire la nostra app e poi si bloccava anche all'avvio. Ho ignorato il problema perché stava lavorando sui nostri dispositivi e ho pensato che avesse qualcosa a che fare con le chiavi di Google Maps o Keystore.

Ora la nostra app si blocca su tutti i dispositivi quando scaricati dal Play Store. Capisco che non esiste un modo semplice per risolvere questo problema, ma sarebbe gradita una spinta nella giusta direzione.

Inoltre, trovo difficile eseguire il debug di questo problema perché l'app funziona alla grande quando compilato da Eclipse sui nostri dispositivi!

Ecco il log di errore completo che ho riportato:

java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.denederlandsewateren.winkeloord/com.denederlandsewateren.views.StartScreenActivity}: java.lang.ClassNotFoundException: com.denederlandsewateren.views.StartScreenActivity

Ancora una volta I dont tranne una risposta dritto in avanti per questo problema, ma forse qualcuno può far luce su questo problema fornito con questo registro errori.

Answer 1

Quindi è stato davvero ProGuard a strappare il codice dal mio progetto.Io uso ActionBarSherlock e facebook e questo è ciò che ho aggiunto in modo che avrebbe funzionato:

# ActionBarSherlock 

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

-keep interface android.support.** { *; } 

-keep class com.actionbarsherlock.** { *; } 

-keep interface com.actionbarsherlock.** { *; } 




# Keep line numbers to alleviate debugging stack traces 

-renamesourcefileattribute SourceFile 

-keepattributes SourceFile,LineNumberTable 

Questo per Facebook:

-keepclassmembers class * implements java.io.Serializable 
{ 
    private static final java.io.ObjectStreamField[] serialPersistentFields; 
    private void writeObject(java.io.ObjectOutputStream); 
    private void readObject(java.io.ObjectInputStream); 
    java.lang.Object writeReplace(); 
    java.lang.Object readResolve(); 
} 

Answer 2

Bene, ti suggerisco di concentrarti sulla differenza tra la build che stai facendo da Eclipse e la build che stai fornendo al Play Store.

Se riesci a riprodurre l'errore che vedi dal PlayStation, mentre lo crei con Eclipse e lo collaudi, troverai sicuramente la risposta.

Quello che posso pensare sono i certificati che l'app viene firmata, ma non sembra essere così. Tuttavia dovresti pensare di più alla differenza tra i due .apk: la build per sviluppatori e la build per playstore.

Come .apk sono fondamentalmente archivi, è possibile decomprimerli entrambi, vedere le differenze tra di loro. È necessario utilizzare un dedexer per provare e decompilare le due istanze di classes.dex (vedere decompiling DEX into Java sourcecode). Probabilmente sarà un codice altamente offuscato, ma dovresti cercare classi mancanti o qualcosa del genere.

Spero che tu abbia capito bene.

Fai clic destro sulla cartella del progetto => Proprietà => Java Build Path => Ordine ed esportazione => seleziona la casella "Librerie private Android" se non selezionata. E funziona!
