首先是在百度地圖官網註冊賬戶，然後進行申請api，其他就不囉嗦了，獲取sha1碼方法

參考如下文章  http://jingyan.baidu.com/article/a681b0de0f860f3b184346bc.html

上程式碼

-===================================================================
需要給build.gradle中新增如下程式碼

/**
 * 目前 Android Studio不支援自動新增 .so檔案（Eclipse是支援的），所以我們需要手動載入libs下的.so的動態庫
*/
sourceSets {
    main() {
        jniLibs.srcDirs = ['libs']
    }
}
