So I came up with what I thought was a great solution which worked
initially -
Intent resolveIntent = new Intent(Intent.ACTION_VIEW,
Uri.fromParts("http", "", null));
PackageManager pm = context.getPackageManager();
ResolveInfo ri = pm.resolveActivity(resolveIntent,
PackageManager.MATCH_DEFAULT_ONLY);
String packageName = ri.activityInfo.packageName;
String activityName = ri.activityInfo.name;
Intent webIntent = new Intent();
webIntent.setComponent(new ComponentName(packageName, activityName));
context.startActivity(webIntent);
This worked! Yea. But then I thought what if there was ANOTHER
activity on the system that services http data? Which activity would
be selected? So I created one to try it out. My dummy activity has
this intent filter -
<intent-filter android:label="Dummy HTTP Activity">
<action android:name="android.intent.action.VIEW" />
<category
android:name="android.intent.category.DEFAULT" />
<category
android:name="android.intent.category.ALTERNATIVE" />
<category
android:name="android.intent.category.SELECTED_ALTERNATIVE" />
<data android:scheme="http" />
</intent-filter>
I tried it without the ALTERNATIVE and SELECTED_ALTERNATIVE categories
also. Either way I now get an intent for
com.android.internal.app.ResolverActivity and a chooser dialog that
says "No application can perform this action". Darn. There are TWO
apps that can perform the action. Why does it say there are none?
Any tips on what I should be doing differently here?
