The API call is in a sample application to demonstrate that Android
probably does not have an extension to MIME-type mapping for this
particular MIME-type.
The main application I am working on does register itself for the
MIME-type in question (via AndroidManifest.xml) but still does not
receive the intents and I think that's because of the lack of mapping
for this MIME-type in Android.
Is there a way I can add this mapping to Android?
For example, add a mapping for *.xyz to application/xy+z and vice
versa so that when the user taps on ABC.xyz in a 3rd-party file
explorer, an intent with MIME-type application/xy+z is sent to
applications who register for it in their AndroidManifest.xml.
Thanks,

what AndroidManifest.xml is for.

Hi,
I want to register my application for files of a certain popular and
well-documented MIME-type.
The problem is that Android does not seem to recognize this MIME-type.
The following sample code demonstrates this:
package com.example.helloandroid;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.widget.TextView;
public class HelloAndroid extends Activity {
/** Called when the activity is first created. */
�...@override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView tv = new TextView(this);
tv.setText(Hello, Android);
setContentView(tv);
String extn =
android.webkit.MimeTypeMap.getFileExtensionFromUrl(/data/a.xyz);
String xyzMimeType =
android.webkit.MimeTypeMap.getSingleton().getMimeTypeFromExtension
(extn);
Log.d (HelloAndroid, extn: + extn + | xyzMimeType: +
xyzMimeType);
}
}
The MIME-type returned by this API is NULL although it correctly
returns the extension (extn = xyz).
So in my main application, if I skip the data android:mimeType=...
/ line in the manifest file, the application does not receive the
intent which means it is not launched.
And there seems to be no way to specify android:mimeType as NULL.
I also tried using data android:mimeType=* /, but with that, I get
an error saying Malformed XML.
(Read about it here:

Could someone please throw some light on this?
Thanks,
