1. Reason: Today I will talk about multi-channel fast packaging- Python script multi-channel packaging .
2. Background: Why do you want to talk about this? I believe that we all have the same troubles in Android development. When the project is launched, if the business of the project is large enough, the app requires dozens or even hundreds of channels to support these businesses. There are two types of traditional packaging:
1. AS's gradle configuration channel (channel) packaging. 2. Use the reinforcement tool (360 reinforcement tool) to create the channel package.
But what they all have in common is slowness . Not generally slow. It takes more than an hour to type out dozens of packages, and there is no guarantee that every package will be successful.
3. Solution: At first, we used Meituan’s Waliduo channel to package, but it requires gradle configuration, and it cannot be taken out as an independent tool.
Then I found out that another Python script package provided by Meituan is very fast, so it is necessary to talk about it.
4. Python script implementation:
-
First look at the directory:
-
Put the company's keystore file in the doc folder
-
lib into CheckAndroidV2Signature.jar and walle-cli-all.jar files.
-
ApkResiger.py is the configuration for running signatures, signature checks, write channels, alignment, etc.
-
channel is a collection of channel numbers.
-
config.py is the signature and path configuration.
-
Doumijagubao.apk is the apk package that you need to write to the channel. This apk needs to be reinforced without re-signing.

6. Operation mode:
Open the command line --> cd to the parent directory of the script --> run python ApkResigner.py.
After success, you can send the first parent directory with an additional channels folder, which contains all channel packages. Is it soon?
If it works quickly, give it a thumbs up.
