Steps to build and install a release APK in C3 with Mobile Advert , and without Android studio
I have got the banner, interstitial, and rewarded videos to work, with this method below.
Test OS, Windows 10 64 bit
Choose export >-android 6.0+
I did not minify.
Then I chose >-unsigned release build.
Sign your APK, with a .Keystore file
Use an existing .Keystore or make a new one, with appropriate software e.g https://shatter-box.com/knowledgebase/a ... pk-signer/
Download Java, if it is not already installed i have java jdk 1.8.0_131 installed.
Download your apk, and put it in Program files>Java Bin directory
I signed with jarsigner from the Program files>Java Bin directory, also I made sure that I had my .Keystore file and my C3 APK in the same directory, to save any lengthy file pathnames.
When in the Java Bin Directory hold down SHIFT & Right Click your mouse and choose Open powershell window .
Use this Command at the prompt>
Replacing below with your the details from your .Keystore file , where appropriate.
.\jarsigner -verbose -keystore yourkeystorefilenamehere.keystore -storepass yourstorepasshere -keypass yourkeypasshere yourAPKhere.apk yourALIAShere
Then Align your APK
Then the only way I could Align it was from a program called apk-signer, found here https://shatter-box.com/knowledgebase/a ... pk-signer/
Then I sent the signed and aligned file to my mobile phone, by gmail attachment, you must enable developer mode, and enable download from unkown sources.
You should now be prompted to install.
Following these steps seemed to work for me, without the need of Android Studio.
Hope this helps
Cheers
