Fix launching of activities that I broke.

        Intent intentToResolve = new Intent(Intent.ACTION_MAIN);

        intentToResolve.addCategory(Intent.CATEGORY_INFO);

        intentToResolve.setPackage(packageName);

        ResolveInfo resolveInfo = resolveActivity(intentToResolve, 0);

        List<ResolveInfo> ris = queryIntentActivities(intentToResolve, 0);

        // Otherwise, try to find a main launcher activity.

        if (resolveInfo == null) {

        if (ris == null || ris.size() <= 0) {

            // reuse the intent instance

            intentToResolve.removeCategory(Intent.CATEGORY_INFO);

            intentToResolve.addCategory(Intent.CATEGORY_LAUNCHER);

            intentToResolve.setPackage(packageName);

            resolveInfo = resolveActivity(intentToResolve, 0);

            ris = queryIntentActivities(intentToResolve, 0);

        }

        if (resolveInfo == null) {

        if (ris == null || ris.size() <= 0) {

            return null;

        }

        Intent intent = new Intent(intentToResolve);

        // Note: we do NOT fill in the component name; we'll leave the

        // Intent unspecified, so if there are multiple matches within the

        // package something reasonable will happen.

        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

        intent.setClassName(ris.get(0).activityInfo.packageName,

                ris.get(0).activityInfo.name);

        return intent;

    }

     *

     * 

     * @return Returns either an Intent that can be used to

     * @return Returns either a fully-qualified Intent that can be used to

     * launch the main activity in the package, or null if the package does

     * not contain such an activity.
