Probably the simplest thing is to write the data you want to pass to a file on the device in /data/data; your Android app can read the device trivially (perhaps make it a .properties file and use java.util.Properties to read it in). To write it out, use this kind of task in your build.gradle file (and use the correct path to the adb command for your setup):

task writeValue(type:Exec) {
    commandLine '/usr/local/bin/adb', 'shell', 'echo \'API_SERVER=http://10.0.2.2/myapp/\' > /data/data/values.properties'
}

There's documentation on Gradle exec tasks at http://www.gradle.org/docs/current/dsl/org.gradle.api.tasks.Exec.html

You can execute this task manually from Android Studio by using the Gradle tasks view:
