Android 2.2 Webview導致OpenGL ES API沒有當前上下文（每個線程記錄一次）

Question

首先，感謝您閱讀本文並提前幫助解決此問題。 我目前正在爲Android創建一個webshel​​l來運行Webapps，這是在Android 2.2 SDK上運行的。

這是我在我的主類代碼：

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; 
    } 
} 

而在去年

當我調試我的應用程序（這是通過USB在Android 4.0手機完成）出現的問題但不是最不重要的是運行的xml im：

<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> 

我知道這個配置幫助了其他rs：

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

但是，這是SDK的2.3.3以上，我運行的SDK不支持此功能。

我真的希望你能幫助我解決這個問題。

由於提前，

Answer 1

要獲得android:hardwareAccelerated財產，還支持API 8（2.2），設置targetSdkVersion至11，但離開minSdkVersion，因爲它是：

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

當運行在API 11之前的設備上，hardwareAccelerated只會被忽略。
