i need in solving issue:

i developing application transfer file application other phone using blue-tooth. when wanted transfer image file, part of code went follows:

     intent.settype("image/*");      i.putextra(i.extra_stream, uri);      //here uri has uri of image want send. 

and android manifest file went follows:

 <intent-filter>         <action android:name="android.intent.action.main"         <category android:name="android.intent.category.launcher" />        <category android:name="android.intent.category.browsable" />         <data android:scheme="file" />        <data android:mimetype="image/*" />        <data android:host="*" />    </intent-filter>

   f = file.createtempfile("card", ".xcard", getexternalcachedir());

try put file in bluetooth directory, worked me.

string root = environment.getexternalstoragedirectory().tostring(); intent = new intent(intent.action_send); i.settype("text/html"); file f = new file(root + "/bluetooth/test2.html"); i.putextra(intent.extra_stream, uri.fromfile(f)); startactivity(intent.createchooser(i, "send page"));
