Gradle buildConfigField with integer variable

Question

I would like to define a build config filed where I can use a variable defined in the gradle script it self:

def someVar = 512 android { ...     buildConfigField 'int', 'SOME_INT_FIELD',  someVar } 

But this produces following error:

Error:(25, 0) Gradle DSL method not found: 'buildConfigField()'

Possible causes:

The project 'PROJECT' may be using a version of Gradle that does not contain the method.

The build file may be missing a Gradle plugin.

I could use quotes like:

def someVar = 0 android { ...     buildConfigField 'int', 'SOME_INT_FIELD',  '"' + someVar + '"' } 

But this comes to a compiler error in BuildConfig

// Fields from default config. public static final int SOME_INT_FILED = "512"; 

---

So for now I stay with:

def someVar = 0 android { ...     buildConfigField 'String', 'SOME_INT_FIELD',  '"' + someVar + '"' } 

and use it like:

final int value = Integer.valueOf(BuildConfig.SOME_INT_FIELD);

Does anybody has better solution or do I use buildConfigField wrong?

(I also tried using parentheses in combination with any of possibility above.)

Answer 1

I found a solution, so maybe this answer will help somebody in future.

def String globalVersionCode  defaultConfig {     applicationId "com.test.gradle.build"     minSdkVersion 15     targetSdkVersion 22     versionCode 1     versionName "0.1"      globalVersionCode = versionCode }  buildTypes {     release {          buildConfigField ("int", "DatabaseVersion", globalVersionCode)     } } 

And now in java I can get DatabaseVersion variable:

public static final int DB_VERSION = BuildConfig.DatabaseVersion;
