推荐答案

您将不得不使用意图过滤器，下面

You will have to use intent filters, Sample code below

    PackageManager packageManager = getPackageManager();

    Intent baseIntent = new Intent(ACTION_PICK_PLUGIN);
    baseIntent.addCategory("matching.catagory");

    List<ResolveInfo> activities = packageManager.queryIntentActivities(baseIntent, PackageManager.GET_RESOLVED_FILTER);

然后使用以下火的意图，

Then fire intent using the following,

Intent baseIntent = new Intent(activities.get(indexOfChild).filter.getAction(0));
baseIntent.addCategory(activities.get(indexOfChild).filter.getCategory(0));     
baseIntent.setComponent(newComponentName(activities.get(indexOfChild).activityInfo.packageName,activities.get(indexOfChild).activityInfo.name));
startActivity(baseIntent);

我希望它能帮助。
