android开发异常信息收集程序代码

首先创建全局的Application ，此Application全局通用。

package com.demo.utils;

import com.demo.exception.CrashHandler;
import android.app.Application;
/**
 * 全局的context,任意位置调用
 * @author Administrator
 *
 */
public class GlobalApplication extends Application
{
    private static GlobalApplication instance;

    public static GlobalApplication getInstance()
    {
        return instance;
    }

    @Override
    public void onCreate()
    {
        super.onCreate();
        instance = this;
        CrashHandler crashHandler = CrashHandler.getInstance();//这是收集异常信息的单例类，具体代码请看下文
        crashHandler.init(getApplicationContext());//初始化
    }
}
