Android 不歸路之百度地圖API學習（導航篇）

在學習百度地圖api 導航篇時 不論怎麼仿寫官方DEMO 都不能初始化導航引擎 糾結了兩天

在LBS論壇上找到同樣問題 傳送門初始化導航失敗

文中解決方法 主要有三種：

目前demo中初始化導航失敗有三種情況：

1. 調用BaiduNaviManager.initEngine接口時activity為空；

2.系統裝載so庫(loadLibrary)時失敗，請確定BaiduNaviSDKDemo\libs\armeabi\libapp_BaiduNaviApplib_v1_0_0.so檔案存在，并且不要改名；

3.其他原因導緻native層引擎初始化失敗。這種失敗會回調NaviEngineInitListener.engineInitFail()接口，請在調用initEngine指定NaviEngineInitListener參數時在接口engineInitFail中列印一下，看看是否屬于這種情況。

我的解決方案是将demo的assets檔案夾下的BaiduNaviSDK_Resource_v1_0_0png,channel檔案拷貝到自己的工程！屬于第三種情況吧。

assets檔案夾在打包會原封不動的打包進去 

官方沒有說明這個是導航功能必要的檔案，導緻初始化失敗。
