package com.example.jy110;

import org.apache.cordova.DroidGap;

import android.annotation.TargetApi;
import android.os.Bundle;


public class Jy110Activity extends DroidGap {
    private int retryCount = 0;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        super.setIntegerProperty("splashscreen", R.drawable.splash);
        super.init();
        if(android.os.Build.VERSION.SDK_INT > android.os.Build.VERSION_CODES.ICE_CREAM_SANDWICH_MR1) {
            fixJellyBeanIssues();
        }
        super.loadUrl("file:///android_asset/www/index.html",5000);
    }

    @TargetApi(16)
    protected void fixJellyBeanIssues() {
        System.out.println(super.appView.toString());
        try {
            super.appView.getSettings().setAllowUniversalAccessFromFileURLs(true);
        } catch(NullPointerException e) {
            System.out.println(e.toString());
        }
    }

    @Override
    public void onReceivedError( int errorCode, String description, String failingUrl)
    {
        if(retryCount < 3) {
            retryCount++;
            super.loadUrl("file:///android_asset/www/index.html");
        } else {
            super.loadUrl("file:///android_asset/www/fail.html");
