dequeueBuffer: impossibile rimuovere i buffer multipli senza impostare il conteggio del buffer

Question

Viene visualizzato l'errore di seguito su Android 4.4.2 Moto X 2013 in un'app WebView 5.0.0 di Rhomobile. L'applicazione è compilato con SDK 19 e il livello di minAPI 17.

Dopo alcune ricerche sembra che questo è un problema con Snapdragon dispositivi GPU 800/Adreno:

https://code.google.com/p/android/issues/detail?id=63738 https://code.google.com/p/android/issues/detail?id=71742

Disabilitare l'accelerazione hardware è non proprio un'opzione, perché rende la WebView molto lenta.

Dal momento che l'errore è:

dequeueBuffer: can't dequeue multiple buffers without setting the buffer count 

Come posso impostare il conteggio buffer nel com.rhomobile.rhodes.RhodesActivity?

Answer 1

provare ad attivare più dex, si risolverebbe il problema On Gradle

android { 
    defaultConfig { 
     ... 
     minSdkVersion 15 
     targetSdkVersion 26 
     multiDexEnabled true 
    } 
} 

dependencies { 
    compile 'com.android.support:multidex:1.0.1' 
} 

Il nome attributo aggiuntivo manifesta all'applicazione

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.example.myapp"> 
    <application 
      android:name="android.support.multidex.MultiDexApplication" > 
     ... 
    </application> 
</manifest>
