[英]Activity Not FOund Exception While Opening File android
I'm getting this exception 我收到这个例外
06-28 21:00:48.792: W/System.err(10272): android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=file:///mnt/sdcard/01 - 3G - Kaise Bataaoon [SongsPK.info] (2).mp3 typ=audio/mpeg }
I'm trying to open this file via these code : 我正在尝试通过以下代码打开此文件:
File sdCard = Environment.getExternalStorageDirectory();
Intent intnt = new Intent(Intent.ACTION_VIEW);
String ext = fileToOpen.substring(fileToOpen.lastIndexOf('.')+1) ;
//Intent j = Intent.createChooser(intnt, "Choose an application to open with:");
//startActivity(j);
File fl = new File(sdCard.getAbsolutePath()+"/"+ fileToOpen);
if(fl.exists())
{
Log.d("FILEMANAGERACTIVITY",fl.getPath() + "0"+ ext);
MimeTypeMap mim = MimeTypeMap.getSingleton();
String type= mim.getMimeTypeFromExtension(ext);
intnt.setDataAndType(Uri.fromFile(fl) , type);
startActivity(intnt);
}
Make sure the data and type you are sending in intnt.setDataAndType(Uri.fromFile(fl) , type);
确保要发送的数据和类型为intnt.setDataAndType(Uri.fromFile(fl) , type);
is correct, seems like the Intent.ACTION_VIEW do not have any match for that intent data and hence there's no activity to handle that intent... 是正确的,似乎Intent.ACTION_VIEW与该Intent数据不匹配,因此没有活动可处理该Intent ...
Regards! 问候!
将活动添加到mainfist.xml可能会帮助您
