unable to sign the unsigned APK
You need to remove the -
in front of the keystore
file and add the flag -keystore
:
$ jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my-release-key.keystore F:\mobile\moto\whatever_the_path_is_to_your_apk_file\HelloCordova-release-unsigned.apk alias_name
Generally I use these commands to generate a release build apk
that I will publish in the Google Play Store:
cd ~/Projects/myappname/
cordova build android --release
jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore certificates/myappname-cert.keystore -storepass myappname -keypass myappname platforms/android/ant-build/CordovaApp-release-unsigned.apk myappname
jarsigner -verify -verbose -certs platforms/android/ant-build/CordovaApp-release-unsigned.apk
~/android-sdk-macosx/build-tools/21.1.2/zipalign -v 4 platforms/android/ant-build/CordovaApp-release-unsigned.apk releases/android/myappname1.0.0.apk
Note that I created the dir. certificates
with the .keystore certificate, and the dir. releases/android
where I save all signed apk releases.
To generate a new keystore
file with a new password
:
keytool -genkey -v -keystore certificates/my-release-key.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 10000
Steps to sign Corodva apk using keytool, jarsigner and zipalign are:
1. Generate keystore for your app using keytool:
keytool -genkey -v -keystore android.keystore -alias android_app -keyalg RSA -keysize 2048 -validity 10000
2. Next create a certificate into a pkcs12 keystore format with keytool
keytool -importkeystore -srckeystore android.keystore -destkeystore android.keystore -deststoretype pkcs12
It will create two files in Project_root_dir as android.keystore (with pkcs12) and android.keystore.old (without pkcs12)
3. Sign apk with jarsigner:
jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore android.keystore app-release-unsigned.apk android_app
First time you'll get below error as:
jarsigner: unable to open jar file: app-release-unsigned.apk
Then you just need to move .apk file from
/Project_root_dir/platforms/android/app/build/outputs/apk/release/app-release unsigned.apk
in to Project_root_dir/
Then again run the jarsigner command above, it will sign apk successfully.
4. Finally verify apk:
zipalign -v 4 app-release-unsigned.apk app-release.apk
Your apk is signed successfully, you can publish it in play store.
I hope this will help you.
