我在 Eclipse 中使用 android。使用 phonegap 从资产文件夹运行 HTML5 组件。使用 android 4.0.3 api 的模拟器中没有 Html 组件。
无法加载顶点着色器错误消息正在 logcat 中。
下面给出了我的 Activity 类。在该类中，我使用了 droidGap 类的 loadUrl 方法。
我试图加载一个 HTML5 页面，它实际上是一个登录页面，蓝屏仅在尝试运行项目时出现。
package com.plugin.myapp;
import java.io.IOException;
import java.io.InputStream;
import org.apache.cordova.DroidGap;
import android.content.res.AssetManager;
import android.os.Bundle;
public class MainActivity extends DroidGap {
private static MainActivity instance;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
super.init();
super.loadUrl("file:///android_asset/www/tdc_tutorial.html");
//super.loadUrl("file:///android_asset/www/web/index.html",10000);
}
}
manifest.xml 在下面给出
