在集成了统计SDK(友盟统计，百度统计等)之后，有一个非常有利于测试的功能：错误分析！此功能能够将程序在运行中碰到的崩溃(runtimeException)问题反馈到服务器，帮助开发者改善产品，多适配机器。然而在公司android开发中不集成这些SDK，那应该怎么实现这样的功能呢？下面让我们来看下如何使用UncaughtExceptionHandler来捕获异常。

在Android开发中，常常会出现uncheched Exception 导致程序的crash，为了提供良好的用户体验，并对出错的信息进行收集，以便对程序进行改进，提高程序的健壮性。因此，常使用Thread.UncaughtExceptionHandler来进行处理。

首先在CrashHandlerApplication中进行初始化

CrashHandler crashHandler = CrashHandler.getInstance();
		crashHandler.init(this);

然后我们看看在CrashHandler做了什么操作？

public void init(Context context) {
		mContext = context;
		// 获取handler
		mDefaultHandler = Thread.getDefaultUncaughtExceptionHandler();
		// 实现接口
		Thread.setDefaultUncaughtExceptionHandler(this);
	}

Android系统的“程序异常退出”，给应用的用户体验造成不良影响。为了捕获应用运行时异常并给出友好提示，便可继承UncaughtExceptionHandler类来处理。通过Thread.setDefaultUncaughtExceptionHandler()方法将异常处理类设置到线程上即可。

在本例中第一个界面启动第二个界面之后，在第二个界面有一个bug如下,没有setContentView(R.layout.activity_XXXX);

	super.onCreate(savedInstanceState);

		findViewById(R.id.tv).setOnClickListener(new View.OnClickListener() {

			@Override
			public void onClick(View v) {
				Toast.makeText(SecondAty.this, "onClick", Toast.LENGTH_SHORT)
						.show();
			}
		});

所以启动项目后，点击进入第二个界面，会有崩溃现象，此刻，在CrashHandler就可以捕获全局异常，捕获之后，会在接口方法uncaughtException中去做处理操作，那么我们是怎么处理的呢？

1、mDefaultHandler.uncaughtException(thread, ex);是说如果用户没有处理，则让系统默认的异常处理器来处理

2、我们会对异常做哪些处理操作？存到sd卡手机log信息，然后将log信息封装为json，然后传入到服务器，去做反馈收集

3、处理完之后呢？一般app退出会给用户良好体验，如果直接退出会感觉很low，我们可以友好的定位到某一个界面或者重启app

// android.os.Process.killProcess(android.os.Process.myPid());
			// System.exit(1);

			// 重新启动程序
			Intent intent = new Intent();
			intent.setClass(mContext, MainActivity.class);
			intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
			mContext.startActivity(intent);
			android.os.Process.killProcess(android.os.Process.myPid());

4、然后我们回过头来，看看如何进行log日志处理的？

（4-1）我这个例子是封装为json字符串，传给服务器的，首先根据需求，我们需要构造请求头、请求体

private JsonParameters headParameters = null;
private JsonParameters bodyParameters = null;

（4-2）JsonParameters中就是构造键值对信息，我们这个例子就简单收集下手机信息即可

if (devicemodel != null)
			headParameters.add("devicemodel", CrashHandlerApplication
					.getInstance().getDevice());
		if (appversion != null)
			headParameters.add("appversion", CrashHandlerApplication
					.getInstance().getVersion());
		if (osversion != null)
			headParameters.add("osversion", CrashHandlerApplication
					.getInstance().getOsVersion());

（4-3）log产生后，可以将log日子，输出，在保存到sd卡的同时，进行封装请求体信息

以下代码是将log信息，输出字符串

	Writer writer = new StringWriter();
		PrintWriter printWriter = new PrintWriter(writer);
		// 输出 printStackTrace 堆栈信息
		ex.printStackTrace(printWriter);
		Throwable cause = ex.getCause();
		// 循环着把所有的异常信息写入writer中
		while (cause != null) {
			cause.printStackTrace(printWriter);
			cause = cause.getCause();
		}
		printWriter.close();
		// 将log信息输出字符串
		String result = writer.toString();

如下就是本例子的错误日志输出结果：

 result==>java.lang.RuntimeException: Unable to start activity
	 *         ComponentInfo
	 *         {com.example.crashhandler/com.example.crashhandler.SecondAty}:
	 *         java.lang.NullPointerException: Attempt to invoke virtual method
	 *         'void android.view.View.setOnClickListener(android.view.
	 *         View$OnClickListener)' on a null object reference

（4-4）然后存到sd卡saveCrashToFile方法就不介绍了

（4-5）然后就封装为json的项目需要格式，工具类就不介绍了，一下就是日志log的Json格式

String requestJson = ProtocolUtil.buildJSONPacketBody(headParameters,
				bodyParameters);

		 *   }

（4-6）在JSONUtil才是封装为json对象，而ProtocolUtil只是我公司代码中的数据格式

（4-7）最后就传服务器，判断网络，接受服务器反馈成功即可
