I'm implementing n-layer PreferenceActivities 1st layer
PreferenceActivity is loaded from preference-headers.
First header creates fragment of settings which is a
PreferenceFragment. Second is a browser activity (2nd is an example
from developer.android.com) which opens specified Url. The third one I
want to be a next level of PreferenceAtivity that also will be loaded
from preference-headers.
First two work fine but 3rd is crashing an app with the exception:
"android.content.ActivityNotFoundException: No Activity found to
handle Intent { act=android.intent.action.VIEW
dat=com.mycompany.myapp.ui.MyPreferenceActivity} "
MyPreferenceActivity declared in the manifest file. Probably
declaration of activity in main_headers.xml is wrong, but I didn't
find in references any tip how to do it correct. Tried several
variations, they didn't work.
Example I used:
http://developer.android.com/reference/android/preference/PreferenceActivity.html
Any thoughts why it doesn't work for me or how the next
PreferenceActivity can be called? Basically I just need to start an
activity from header, that should be really simple but I'm missing
something.
public class MySettings extends PreferenceActivity
{
@Override
public void onBuildHeaders(List<Header> target)
{
loadHeadersFromResource(R.xml.main_headers, target);
}
}
main_headers.xml:
<?xml version="1.0" encoding="utf-8"?>
<preference-headers
xmlns:android="http://schemas.android.com/apk/res/android"; >
<header android:title="Custom Settings"
android:fragment="com.mycompany.myapp.ui.SettingsFragment" />
<header android:title="Intent"
android:summary="Launches an Intent.">
<intent android:action="android.intent.action.VIEW"
android:data="http://www.android.com"; />
</header>
<!-- and something like this -->
<header android:title="Another Preference Activity">
<intent android:action="android.intent.action.VIEW"
android:data="com.mycompany.myapp.ui.MyPreferenceActivity" />
</header>
</preference-headers>
