How to fix android.defaultConfig.versionCode is set to -1, but it should be +ve error

Rahulkumar2020 · December 28, 2020, 8:20pm

Hello team, i don’t know coding just try to learn and do by watching videos or tutorials,
Though i have cryptomator but i want to build it myself with provided source code.
So i simply download cryptomator source code zip and extract it. Then select “open an existing project” in android studio and select these source code folder.
Everything goes fine then i tried to install it on my mobile but it told me that " android.defaultConfig.versionCode is set to -1 it should be +. "
Would someone like to help me here please?
Thankyou

I think you downloaded the source code instead of cloning the git repository?

github.com

cryptomator/android/blob/develop/build.gradle#L22-L39


def getVersionCode = { ->
	try {
		def branchName = new ByteArrayOutputStream()
		exec {
			commandLine 'git', 'rev-parse', '--abbrev-ref', 'HEAD'
			standardOutput = branchName
		}
		def appBuild = new ByteArrayOutputStream()
		exec {
			commandLine 'git', 'rev-list', '--count', branchName.toString().trim()
			standardOutput = appBuild
		}
		return Integer.parseInt(appBuild.toString().trim()) + 1958 // adding 1958 for legacy reasons
	}
	catch (ignored) {
		return -1
	}
}

To fix this you can clone the repo and use it as it is or you can set

github.com

cryptomator/android/blob/develop/build.gradle#L44


		return Integer.parseInt(appBuild.toString().trim()) + 1958 // adding 1958 for legacy reasons
	}
	catch (ignored) {
		return -1
	}
}
allprojects {
	ext {
		androidApplicationId = 'org.cryptomator'
		androidVersionCode = getVersionCode()
		androidVersionName = '1.5.11-SNAPSHOT'
	}
	repositories {
		mavenCentral()
		maven {
			url "https://maven.google.com"
		}
		flatDir {
			dirs '../libs'
		}

to something > 0, e.g. androidVersionCode = 1

Yes, 1.5.11 is currently beta software. Google didn’t review this version yet but it will be in the Playstore beta channel soon.

If you are talking about Dropbox and Onedrive: You have to provide API keys to access this cloud services. In case of Dropbox, also have a look into this issue: Cannot authenticate inside Dropbox · Issue #242 · cryptomator/android · GitHub

Press ctrl + shift + n and enter secrets.properties or scroll in your left panel down to the file.
