/**
 * Created by Sean.Ye on 2017/1/17.
 * <p>
 * 抓取原生部分全局的crash信息,打到xlog中
 * <p>
 * 从安卓处理JS传递过来的异常类{@link com.facebook.react.modules.core.ExceptionsManagerModule}，可以看到有两种异常：
 * {@link com.facebook.react.modules.core.ExceptionsManagerModule#reportFatalException}：直接抛出 JavascriptException
 * {@link com.facebook.react.modules.core.ExceptionsManagerModule#reportSoftException}：写入日志Flog.e(...)
 * 所以本类可以捕获到JS端的fatalException（即JavascriptException）
