Compiling from command line

Currently you cannot compile from command line.

It is not possible to modify an existing APK file without resigning it.

Re-signing an apk

Hi Erel!

I managed to understand the process to edit an apk (I first unzip it, change an xml config file I have in my assets folder, and rezip it).

Now I am in the process to re-sign it ... I am using the .keystore that apps4android created with my key. But I wonder, on jarsigner sintax (the signing util inside the java sdk, which is used in every tutorial on re-signing an apk) .... What is the "alias_name" given by basic4android to the key it created for me ?

I tried lots of strings, including the three strings I typed when creating the key in basic4android, but it seems that you are not using any of those as the "alias name".

I might also be needing the keystore password (I dont know if you leave it in blank, or you just use the same passwords that basic4android asks for the key itself)...

The sintax and error is:

C:\prueba>C:\"Archivos de programa"\Java\jdk1.6.0_25\bin\jarsigner -keystore mis
llaves.keystore -storepass <dontknow> -keypass <secret> prueba_u.apk alias_name
jarsigner: Certificate chain not found for: alias_name. alias_name must reference a valid
KeyStore key entry containing a private key and corresponding public key certif
icate chain.

C:\prueba>

Thanks,

Enrique

Nevermind .... I found out

Erel,

You used the "b4a" alias name for the key inside basic4android keystore. I could see it by using a freeware util called KeyStore Explorer (version 4.0.1) And the keystore password is the same as the key password, which is the one that is on clear view on the option about signing key under the basic4android IDE "tools" menu

Well done
