Android 2.2 Webview causa OpenGL ES API senza contesto corrente (registrato una volta per thread)

Question

Prima di tutto, grazie per aver letto questo post e in anticipo per avermi aiutato in questa materia. Attualmente sto creando un webshell per Android per eseguire Webapps, questo è in esecuzione su Android 2.2 SDK.

Il problema si presenta quando il debug la mia domanda (questo viene fatto su un Android 4.0 Phone tramite usb):

09-28 11:32:32.415: D/dalvikvm(25629): Debugger has detached; object registry had 576 entries

Questo è il mio codice della mia classe principale:

package com.android_api8_webshell; 

import android.os.Bundle; 
import android.app.Activity; 
import android.util.Log; 
import android.view.Menu; 
import android.webkit.WebView; 
import android.webkit.WebSettings; 

public class Main extends Activity { 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     WebView myWebView = (WebView) findViewById(R.id.webView1); 

     WebSettings webSettings = myWebView.getSettings(); 
     webSettings.setJavaScriptEnabled(true); 

     Log.v("StringUrl", "String: " + getResources().getText(R.string.url)); 

     myWebView.loadUrl(getResources().getText(R.string.url).toString()); 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     getMenuInflater().inflate(R.menu.main, menu); 
     return true; 
    } 
} 

E per ultimo ma non meno importante, è l'im xml in esecuzione con:

<resources> 
    <string name="title_activity_main">Main</string> 
    <string name="url">http://www.cidesign.nl</string> 
    <string name="app_name">Android_API8_WebShell</string> 
    <string name="menu_settings">Settings</string> 
</resources> 

Sono a conoscenza di questa configurazione che ha aiutato altri rs:

<application android:hardwareAccelerated="true" ...> 

Questo è comunque per lo SDK di sopra 2.3.3, l'SDK sto correndo con il supporto doesnt questa funzione.

Spero davvero che tu possa aiutarmi in questa faccenda.

Grazie in anticipo,

David

Answer 1

Per ottenere android:hardwareAccelerated proprietà e ancora sostenere API 8 (2.2), impostare targetSdkVersion-11 ma lasciare minSdkVersion così com'è:

<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="11" /> 
<application android:hardwareAccelerated="true" ... 

Quando run su dispositivi pre-API 11, hardwareAccelerated verrà semplicemente ignorato.
