Android uses Android Studio + Gradle or command line for APK signature Package

Official Document: Https://developer.android.com/tools/publishing/app-signing.html

1. The default is debug mode, using the signature file in: $HOME/.android/debug.keystore

2. Release Mode Signature:

build.gradle:

Android {signingconfigs {releaseconfig {keyalias ' stone ' keypassword ' mypwd ' storefile file ('/users/stone/documents/ Project_as/myapplication/stone.keystore ') Storepassword ' MyPwd '}}        buildtypes {           release {             ...             Signingconfig signingconfigs.release           }}}        

Signingconfigs is the signature configuration. Configuration name releaseconfig{//config content}

The configuration name for Signingconfigs when you specify release in Buildtypes

Execute Gradle command, $ gradle assemblerelease

Compile and publish. An unsigned apk and an already signed apk can be seen under build/outputs/apk/.

If the signature file is not used, use debug mode's debug signature. That will generate a debug signature apk

3. Signing the password is not secure in Gradle:

Signingconfigs {//gradle assemblereleasemyconfig {storefile file ("Stone.keystore") Storepassword System.console (). ReadLine ("\nkeystore Password:") Keyalias "Stone" Keypassword system.console (). ReadLine ("\nkey Password:")}}

This will require the password to be entered when the command executes the command.

4. Packaging with Android Studio signature

Menu Build > Generate signed APK

5. Automatic signature packaging using Android Studio

A. Open project structure (cmd+;)

B. Select the moudle you want to build, open signing, add Config

When execution is complete, the signingconfigs{config {...} is automatically added to the Build.gradle. of information

C. Open Build Types > Release

Select the defined configuration in the signing config

Zip align enabled defaults to True to enable optimized apk operation

D. $ gradle Build

The compilation type defined in build types is output in the build/outputs/apk/directory

Such as:

myapplication-debug-unaligned.apk
myapplication-debug.apk
myapplication-release-unaligned.apk
myapplication-release-unsigned.apk
myapplication-release.apk

6. Use the Android SDK and the JDK command signature package apk

Create a signature
keytool-genkey-v-keystore stone.keystore-alias stone-keyalg rsa-keysize 2048-validity 10000 generating signature files
Sign the APK
jarsigner-verbose-sigalg sha1withrsa-digestalg sha1-keystore stone.keystore unsigned.apk Stone does not generate new files
Detect if the APK is signed
jarsigner-verbose-certs-verify signed.apk
Optimize APK
Zipalign-f-V 4 signed_unaligned.apk signed_aligned.apk
