Solution 1:

Given a ResolveInfo named launchable:

ActivityInfo activity=launchable.activityInfo;
ComponentName name=newComponentName(activity.applicationInfo.packageName,
                                     activity.name);
Intent i=newIntent(Intent.ACTION_MAIN);

i.addCategory(Intent.CATEGORY_LAUNCHER);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK |
            Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
i.setComponent(name);

Solution 2:

Create an new Intent by this way.

    intent.setClassName(resolveInfo.activityInfo.applicationInfo.packageName,
            resolveInfo.activityInfo.name);
    startActivity(intent);
