A quick multi-threaded GUI signer tool that will build with the demo version of purebasic. Not tested on Linux or OSX but you can just add forward slash support. It needs to be ran as admin because of modern Windows file system sandboxing.

UPDATE 6/11/17:
  • Added UI for -dname so no more manual CLI stuff
  • You can now save field values across sessions by checking bottom-left checkbox

Code: Select all

;Android .apk signer

;get paths for JDK and SB
Global path$
Global jdk$
sb$=GetEnvironmentVariable("HOMEDRIVE")+GetEnvironmentVariable("HOMEPATH")+"\AppData\Roaming\SpiderBasic\"
If FileSize(sb$)=-2
  ReadFile(0,sb$+"SpiderBasic.prefs")
  While Eof(0)=0
    line$=ReadString(0)
    If StringField(line$,1," ")="JDK" : jdk$=Mid(line$,FindString(line$,":\")-1,9999999) : EndIf
    If StringField(line$,1," ")="Path" : path$=Left(StringField(line$,3," "),FindString(StringField(line$,3," "),"\Ex")) : EndIf
  Wend
  CloseFile(0)
  If Len(jdk$)=0 : MessageRequester("Error","JDK Path not set in  SB") : End : EndIf
  If Len(path$)=0 : MessageRequester("Error","SB Path not set in  SB prefs file") : End : EndIf
Else

tj1010, just trying out your App Signer (PB5.6), I hit a problem.
After inputting a KeyStore Password and hitting 'Sign', a command window pops up and requests the Password but does not let me edit/paste it.
I assume this is because there are rules regarding password length, acceptable characters etc?

Here is an interesting looking signer app: APK Signer from Hai Bison

Well, apk-signer seems to work well enough but it is a pitta to use! However, it does seem to cover more ground than tj1010's signer, requesting developer's name and location for example, similar to Windows OS digital signature info.

My tool no longer requires manual CLI input(I just had to add -dname fields in UI). It already did everything the mentioned tool does. That just set -dname with UI fields so no CLI popup and input.

FYI if the container already exists keytool just gracefully fails and jarsigner just uses existing container. You can delete containers using the -delete command with keytool.

I've read the full Oracle docs and this is about all there is to do with Android APK signing. I guess I could improve UI/UX later but it's efficient now. There is also v2 signing with 7.0+ but 7.0+ still has legacy support.

fixed

I don't know about anyone else, but when I use -list command I get a .keystore missing error even though the keystore exists and I get error on duplicate -genkeypair and success on -delete. This doesn't effect this tool, but I was thinking of making a keystore manager using CLI output instead of just remembering from sessions. It's likely a environment variable error even though I have a unmodified install..

Re: How to sign a release APK

Post by AMpos »

I am trying this thing. It installs on my Android 8.0 mobile. Signed with the purebasic app.

Currently I am uploading it to Google Play console, but google says this error:
Has subido un APK con una firma no válida (más información sobre la firma de aplicaciones). Error de apksigner: ERROR (Jar signer D*******.RSA): JAR signature META-INF/D*******.RSA uses digest algorithm SHA-256 and signature algorithm RSA which is not supported on API Level(s) 16-17 for which this APK is being verified
(I changed letters with *)

Any hint?
