加固後，上傳play store， 在 google play store 下載應用安裝後，打開簽名校驗失敗

在Google Play Console.

(Google Play App Signing )簽署您的應用

在建立應用時：

會有個「 Google Play App Signing」 的東西，提示使用。

這個東西會有兩個密鑰：應用簽名密鑰和上傳密鑰

當您準備發佈應用時，使用上傳密鑰簽署您的應用並將它上傳到 Google Play。而後，Google 使用上傳證書驗證您的身份，並使用您的應用簽名密鑰從新簽署 APK 以進行分發。

因此加固後，防止了二次打包後，這個方法就用不了。

 

(Google Play App Signing) 管理應用簽名密鑰

重要提示：選擇加入 App Signing 是永久性操做

Google Play App Signing 是一個自願加入的計劃。若是您願意，也能夠選擇繼續自行管理密鑰。

一旦在 Google Play App Signing 中註冊了應用，您就沒法撤消了。爲了確保應用簽名密鑰的安全，咱們不能從安全服務器上移除密鑰。

 

因此想本身管理本身的密鑰，就要選擇退出 「App Signing」。

1. "CREATE APPLICATION" having the same name which you want to upload before.
2. Click create.
3. After creation of the app now click on the "App releases"
4. Click on the "MANAGE PRODUCTION"
5. Click on the "CREATE RELEASE"
6. Here you see "Google Play App Signing" dialog.
7. Just click on the "OPT-OUT" button.
8. It will ask you to confirm it. Just click on the "confirm" button.

You are ready to Drop your APK file with your signing key. 

這樣就能上傳咱們本身的包，而Google Play 不作處理。

 

應用一旦發佈：

請注意，系統不支援刪除應用程式或重複使用套件名稱。凡是在 Google Play 發佈的應用程式，使用者均可以無限次地從新安裝。

所以，即便將應用程式取消發佈，只要使用者曾安裝過該程式，就能夠不受影響地繼續使用。

不過您能夠藉由取消發佈應用程式，阻止新使用者安裝使用。

 

應用發佈範圍：

1.  選擇應用

2. 選擇 「Store presence」

3. 選擇 「Pricing & distribution」

4. 在 「Countries」 欄目中，「Manage Countries」，管理髮布範圍。

 

Publishing status

Near the top of individual apps’ pages on your Developer Console, you can see your app’s latest publishing status. Whether you’re publishing an app for the first time or making an update, you can use your publishing status to understand your app’s availability on Google Play.

Here are the different statuses that can be displayed for your app:

• Draft: App hasn’t been published on Google Play.
  • Note: If the Publish app option isn’t available, click Why can’t I publish? for more information or check your app’s pages on the left menu to make sure you’ve included all required information for your app.

• Pending publication: App is currently being processed for publishing.

• Published: App is published and available on Google Play.
• Rejected: App has been rejected and wasn’t published due to a violation of Google Play policies. More information about the violation is available near the top of your app’s pages on the Developer Console. Once you make a change to your app to address the violation, you can submit it again.
• Suspended: App is suspended due to a violation of Google Play Policies (Content Policy, Developer Distribution Agreement). An email with details about the suspension is sent to the account owner.
