Signing Your App Manually
You do not need Android Studio to sign your app. You can sign your app from the command line using standard tools from the Android SDK and the JDK. To sign an app in release mode from the command line:

Generate a private key using keytool. For example:

1, keytool -genkey -v -keystore my-release-key.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 10000
2,jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my-release-key.keystore my_application.apk alias_name
3,jarsigner -verify -verbose -certs my_application.apk
4,zipalign -v 4 your_project_name-unaligned.apk your_project_name.apk

 

This example prompts you for passwords for the keystore and key, and to provide the Distinguished Name fields for your key. It then generates the keystore as a file called my-release-key.keystore. The keystore contains a single key, valid for 10000 days. The alias is a name that you will use later when signing your app.
Compile your app in release mode to obtain an unsigned APK.
Sign your app with your private key using jarsigner:
$ jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1
-keystore my-release-key.keystore my_application.apk alias_name
This example prompts you for passwords for the keystore and key. It then modifies the APK in-place to sign it. Note that you can sign an APK multiple times with different keys.
Verify that your APK is signed. For example:
$ jarsigner -verify -verbose -certs my_application.apk
Align the final APK package using zipalign.
$ zipalign -v 4 your_project_name-unaligned.apk your_project_name.apk
zipalign ensures that all uncompressed data starts with a particular byte alignment relative to the start of the file, which reduces the amount of RAM consumed by an app.

jarsigner是工具名稱，-verbose表示將簽名過程中的詳細資料列印出來；
-keystore /yourpath/demo.keystore 之前產生的認證
-signedjar demo_signed.apk 簽名後的apk
demo.apk 需要簽名的apk
demo.keystore 認證的別名

附：查看apk的簽名

Mac下，把apk的尾碼改為zip開啟，然後查看META-INF下的.RSA檔案
Windows下，用winner開啟apk，同樣查看.RSA檔案
執行命令

keytool -printcert -file META-INF/CERT.RSA
1
注意後面檔案的名稱與路徑即可，可以查看到簽名資訊，主要是查看Certificate fingerprints下的MD5與SHA1，這兩個不同就代表著簽名不同。
