アセットをロードするコードは次のとおりです。ファイル名以外のコードは変更していません。
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);
}
MBtilesファイルのアセットフォルダーを読み込めない理由を誰かが確認できるかどうか私の質問はありますか?
