Hey folks,
My application (Ghost SEED) makes heavy use of Linkify for an in-app help
system. I use a fairly standard setup: I linkify text on an activity
displaying help, with the links firing an intent that I filter in the same
help activity. In older versions of Android (2.1, 2.2, etc) this works
fine. On my HTC One S, which runs 4.0.3, it doesn't work. Linkify does
correctly create links, but my activity never gets called with the intent.
Does anyone have an idea what might have changed here?
I'm including the appropriate code snippets below:
-------- From the manifest ---------------------
<activity android:name=".ClientUI.HelpActivity" class="HelpActivity"
android:theme="@android:style/Theme.Dialog">
<intent-filter>
<category android:name="android.intent.category.DEFAULT"/>
<action android:name="android.intent.action.VIEW"/>
<data android:scheme="content"/>
<data android:host="com.ctenophore.gso.help"/>
</intent-filter>
</activity>
-------- From the code that calls Linkify ---------------------
public final static String helpPrefix =
"content://com.ctenophore.gso.help/";
...
public static void LinkifyText(TextView text) {
ArrayList<String> keywords = GSOHelpItems.titles();
StringBuilder sb = new StringBuilder();
boolean gotOne = false;
for (String keyword : keywords) {
if (gotOne)
sb.append('|');
else
gotOne = true;
sb.append("\\b");
sb.append(keyword);
sb.append("\\b");
}
Pattern matcher = Pattern.compile(sb.toString(), Pattern.DOTALL);
Linkify.addLinks(text, matcher, helpPrefix);
}
-------- From the activity ---------------------
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.help);
Uri data = getIntent().getData();
if (data == null) {
// Do some stuff
} else {
String url = data.toString();
// Do some stuff with the url --- NOTE: This is never reached in
Android 4
}
Cheers,
Jim
