Establishing the project

  1. Download HBuilderX and log into your dclould account (required)
  2. New project

Local package

The packaged file

Go back to the previous two levels

You will need to copy the entire \_\_UNI\_\_354F6F0 directory later

Generate the offline packaging Key

The specific methods:…

Generate a certificate

Enter the following commands after installing the JDK

Command format:

Keytool -genkey-alias certificate alias -keyalg rsa-keysize 2048 -validity of the certificate -file name of the keystore certificate


  1. This is the password for the certificate and must be recorded. Let’s say the password is “leonardpwd”.
  2. And then after you type in a bunch of information he’ll ask you if you’re correct, and at that point you have to manually type “yes”
keytool -genkey -alias leonard-app -keyalg RSA -keysize 2048 -validity 36500 -keystore leonard-app.keystore

Check the certificate

-list-v-keystore -app.keystore -app.keystore -app.keystore -app.keystore -app.keystore -app.keystore -app.keystore

The information displayed is similar to the text below, where the SHA1 of the certificate fingerprint will be needed later

Enter keystore password: keystore type: PKCS12 keystore provider: SUN Your keystore contains 1 entry alias: leonard-app Date created: May 31, 2021 Entry type: privateKeyEntry Certificate Chain Length: 1 Certificate [1]: CN=Unknown, OU=Unknown, O=Unknown, L=Unknown, ST=Unknown, C=Unknown CN= UNKNOWN, OU= UNKNOWN, O= UNKNOWN, L= UNKNOWN, ST= UNKNOWN, C= UNKNOWN SERial number: A2AC5FD0886B0130 Mon May 31 10:51:26CST 2021, Expiry Time: Wed May 07 10:51:26CST 2121 Certificate Fingerprint: SHA1: 99:23:00:18:40:20:D1:F3:41:D5:70:6D:38:94:56:58:68:C3:1E:33 SHA256: A9:8 f: 17:63:3 a: shower: 15:1 C: 6 f: B8:30: D7: A4:59:42:99: F8:04:6 0:8 6:8 enter C: 83: B3:1 e: C4:2 e: F3: AA: EB: name of 07 signature algorithm: SHA256Withrsa Principal Public Key Algorithm: 2048-bit RSA Key Version: 3 Extension: #1: ObjectId: Criticality= False SubjectKeyIdentifier [KeyIdentifier [0000: 88 41 F4 2F A9 C5 F4 68 86 D7 6E E9 D5 3D A9 F1 .A./...h..n..=.. 0010: A2 DF 3B 89 ..;. ] ]

  2. Then fill in the relevant information inside SigningConfigs-> Config

    KeyAlias' certificate alias' keyPassword 'certificate password' storeFile file(' certificate path, note double slash ') storePassword 'certificate password'
  3. Click on the top right and Sync Now
