Earthquake is a natural phenomenon with great harm to human beings and usually causes heavy casualties and economic losses. In particular,when an earthquake happens late at night,the consequence will be tragic,for people who are asleep often cannot feel the quake.The quick earthquake report software based on Android perceives the changes of the surrounding environment by invoking the direction sensor and acceleration sensor in smartphones themselves without adding extra hardware devices,and alerts users the occurrence of an earthquake.At the same time,the software can timely obtain the seismic information with official authority released by China Seismic Information Website when the smartphones are connected to the Internet,which is convenient for users to query.The software integrates the correlated earthquake knowledge that can give users guidance and help in either normal time or after being stranded.In addition,the software also realises the function of obtaining users'GPS geographic positioning information and sending short massages of SOS and safety to specified contacts.The whole system is developed and operated using the model of Java +Eclipse +Android,and tested on real mobile phones as well, it achieves the functions of earthquake information,information setting,earthquake monitoring and earthquake knowledge,etc.%地震是一种对人类危害较大的自然现象，常常造成重大的人员伤亡和经济损失。尤其当地震发生在深夜时，人们由于在熟睡中往往意识不到地震的发生，因而更容易导致惨剧的发生。基于 Android 的地震速报软件不需增加额外硬件设备，通过调用智能手机自带的方向传感器、加速度传感器，感知周围环境的变化情况，提醒用户震动的发生。同时软件在手机连接互联网时，可以实时获取中国地震信息网发布的官方权威地震信息，方便用户查询。软件集成了相关的地震常识，可以在平时和被困后给予用户指导和帮助。此外，该软件还实现了获取用户的 GPS 地理位置信息，并给指定联系人发送求救短信和平安短信的功能。整个系统利用Java ＋Eclipse ＋Android 模式开发运行，并使用真机进行测试，实现地震信息、信息设置、地震监测和地震常识等功能。
