本文介绍了如何在Android应用中实现异常捕获和自动重启功能，通过设置全局异常处理器，当应用遇到未处理的异常时，能够触发重启并重新启动指定的Activity，确保用户体验不受严重影响。

public class BaseApplication extends Application implements
		UncaughtExceptionHandler {
	private static Context context;
	private PendingIntent restartIntent;

	@Override
	public void onCreate() {
		// TODO Auto-generated method stub
		super.onCreate();
		BaseApplication.context = getApplicationContext();
		Thread.setDefaultUncaughtExceptionHandler(this);
		init();
	}

	private void init() {
		Intent intent = new Intent(getApplicationContext(), ExceptionActivity.class);
		restartIntent = PendingIntent.getActivity(getApplicationContext(), 0,
				intent, Intent.FLAG_ACTIVITY_NEW_TASK);
	}

	public static Context getContext() {
		return context;
	}

	public static void startActivity(Class<?> activity) {
		Intent intent = new Intent(context, activity);
		intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
		context.startActivity(intent);
	}

	@Override
	public void uncaughtException(Thread thread, Throwable ex) {
		// TODO Auto-generated method stub
		System.out.println("uncaughtException");
		AlarmManager mgr = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
		mgr.set(AlarmManager.RTC, System.currentTimeMillis() + 500,
				restartIntent); // 0.5钟后重启应用的指定Activity
		System.exit(2);//结束当前遇到线程出错的应用。
	}
}
