我有一个基本上存储在用户手机上保存的gpx文件列表的Android应用程序。当用户点击应用程序中的文件名时,它应该提示用户使用他手机上的任何路由应用程序打开gpx文件。现在我正在用Osmand打开文件进行测试。问题是,奥斯曼德正在开放,但随后立即崩溃。从另一个应用程序在Osmand中打开gpx文件
,试图打开该文件中的代码是这样的:
File gpxFile = new File(Path);
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
Uri gpxUri = FileProvider.getUriForFile(view.getContext(), AUTHORITY, gpxFile);
intent.setDataAndType(gpxUri, "application/gpx+xml");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
在GPX文件都这个样子:
<?xml version="1.0"?>
<gpx creator="{CREATOR}" version="1.1" xmlns="http://www.topografix.com/GPX/1/1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.topografix.com/GPX/1/1 http://www.topografix.com/GPX/1/1/gpx.xsd">
<wpt lat="{LAT_1}" lon="{LON_1}">
<name>{WPT_NAME_1}</name>
</wpt>
...
<wpt lat="{LAT_N}" lon="{LON_N}">
<name>{WPT_NAME_N}</name>
</wpt>
<trk>
<name>{TRACK_NAME}</name>
<trkseg>
<trkpt lat="{LAT_1}" lon="{LON_1}"></trkpt>
...
<trkpt lat="{LAT_N}" lon="{LON_N}"></trkpt>
</trkseg>
</trk>
</gpx>
起初我以为这是一些错误的格式gpx文件,但如果我手动打开Osmand并尝试使用“配置地图” - >“Gpx轨道”导入文件,则轨道在地图上显示得很好,包括航点。
LE:这是我的错误时Osmand试图启动:

感谢您的回答,我已检查了所有建议,并且所有内容似乎都是按顺序排列的,但仍然无法正常工作。这些文件是绝对保存的,因为我的应用程序也打开它们并在地图上显示路线,而且这种方式工作得很好。只有当我点击按钮在osmand中打开它们,然后osmand崩溃。 –
有趣。当它崩溃时,Osmand会记录LogCat的任何内容吗? –
我添加了Osmand试图打开时收到的错误 –
