本文主要是介绍android开发异常信息收集程序代码，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
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;}@Overridepublic 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}
}
注意：上面的代码需要在注册清单文件中注册。部分清单如下:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"package="com.demo.test"android:versionCode="1"android:versionName="1.0" ><uses-sdkandroid:minSdkVersion="8"android:targetSdkVersion="18" /><!-- 网络 --><uses-permission android:name="android.permission.INTERNET" /><!-- 访问sdcard --><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /><!-- 获取mac需要的网络状态 --><uses-permission android:name="andorid.permission.CHANGE_CONFIGURATION" /><uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" /><uses-permission android:name="android.permission.CHANGE_WIFI_STATE" /><uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /><applicationandroid:name="com.demo.utils.GlobalApplication"android:allowBackup="true"android:icon="@drawable/app_icon"android:label="@string/app_name"android:theme="@style/AppTheme" ><activityandroid:name="com.demo.activity.MyActivity"android:launchMode="singleTask"android:screenOrientation="landscape"android:theme="@android:style/Theme.NoTitleBar" ><intent-filter><action android:name="android.intent.action.MAIN" /><category android:name="android.intent.category.LAUNCHER" /></intent-filter></activity></activity></application></manifest>crashHandler
