1. 用户能否评论？-是的，用户可以在应用商店中对应用进行评论和评分。

示例代码：

// 打开应用商店页面，让用户进行评分和评论 Uri uri = Uri.parse("market://details?id=com.example.android"); Intent intent = new Intent(Intent.ACTION_VIEW, uri); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(intent);

2. 他们能购买应用内购买吗？-是的，用户可以在应用内进行购买，但需要先将应用发布为正式版。

示例代码：

// 调用内购界面，用户可以进行商品购买 private static final String SKU_ITEM = "com.example.item"; // ... mBillingClient = BillingClient.newBuilder(mContext) .setListener(this) .build(); mBillingClient.startConnection(new BillingClientStateListener() { @Override public void onBillingSetupFinished(BillingResult billingResult) { if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) { List skuList = new ArrayList<> (); skuList.add(SKU_ITEM); SkuDetailsParams.Builder params = SkuDetailsParams.newBuilder(); params.setSkusList(skuList).setType(BillingClient.SkuType.INAPP); mBillingClient.querySkuDetailsAsync(params.build(), new SkuDetailsResponseListener() { @Override public void onSkuDetailsResponse(BillingResult billingResult, List skuDetailsList) { if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK && skuDetailsList != null && skuDetailsList.size() > 0) { SkuDetails skuDetails = skuDetailsList.get(0); BillingFlowParams flowParams = BillingFlowParams.newBuilder() .setSkuDetails(skuDetails) .build(); mBillingClient.launchBillingFlow(getActivity(), flowParams); } } }); } }
