Ho provato più volte ad aggiornare gli strumenti di sviluppo di Android Studio oltre 1.3.1, ma finisco sempre con questo errore di libpng. Ho risolto uno degli errori rimuovendo completamente una dipendenza di tipo Maven (poiché la console gradle indicava esattamente dove si trovava il problema), ma ora sono bloccato con lo stesso errore e nessun puntatore sul punto in cui si trova il file problematico. Mi sto perdendo qualcosa? Ecco il Gradle log della console:errore libpng: non è un file PNG

Ripristino torna a classpath "com.android.tools.build:gradle:1.3.1" sembra risolvere il problema, ma mi piacerebbe iniziare a utilizzare tutte le nuove funzionalità
provare questo http: // StackOverflow.it/a/32883231/5202007 – Tauqir
o questo http://stackoverflow.com/questions/4280398/9-patch-image-error-in-android – Tauqir
Ho preso la via corta e ho semplicemente cancellato tutti i file inutilizzati che avevo nel mio cartella drawable. Questo sembra aver risolto il problema. In futuro mi assicurerò di schiacciare qualsiasi PNG prima di metterli nella cartella dei drawable –
