MBTilesOsmDroidExample未能從資產文件夾加載MBTiles文件

我正在編譯MBTilesOsmDroidExample https://github.com/djcoin/MBTilesOsmdroidExample我收到以下錯誤。MBTilesOsmDroidExample未能從資產文件夾加載MBTiles文件

mbtile文件位於assest文件夾中。

以下是加載資產的代碼。我沒有更改文件名以外的代碼。

private void mapBeginConfig(){ 
    mResourceProxy = new DefaultResourceProxyImpl(getApplicationContext()); 
    SimpleRegisterReceiver simpleReceiver = new SimpleRegisterReceiver(this); 

    File f = new File(Environment.getExternalStorageDirectory(), "military-bene-and-tacan-routes.db"); //change from map.mbtiles 

    IArchiveFile[] files = { MBTilesFileArchive.getDatabaseFileArchive(f) };   
    MapTileModuleProviderBase moduleProvider = new MapTileFileArchiveProvider(simpleReceiver, MBTILESRENDER, files); 

    mProvider = new MapTileProviderArray(MBTILESRENDER, null, 
      new MapTileModuleProviderBase[]{ moduleProvider } 
    ); 

    this.mOsmv = new MapView(this, 256, mResourceProxy, mProvider); 

}

我的問題是否有人可以檢查爲什麼無法加載MBtiles文件資產文件夾？

Environment.getExternalStorageDirectory（），「軍事好處，和塔康-routes.db」

這種說法是指沒有SD卡的資產。將您的.db文件放在SD卡上，它將運行

它沒有工作。 – user914425 2015-04-25 16:41:34

OSMDroid只會從資產文件夾執行原始圖像。數據庫必須位於/ sdcard/osmdroid或設備上的其他位置。爲了使瓷磚加載ITileSource名稱必須與數據庫中瓷磚圖層的名稱相匹配。你可以編寫採用現有的數據庫加載器來刪除該檢查，這可能會簡化你的工作
