This is the code for changing output application file name (.apk). The name can be configured by assigning a different value to newName
android {
applicationVariants.all { variant ->
def newName = "ApkName";
variant.outputs.each { output ->
def apk = output.outputFile;
newName += "-v" + defaultConfig.versionName;
if (variant.buildType.name == "release") {
newName += "-release.apk";
} else {
newName += ".apk";
}
if (!output.zipAlign) {
newName = newName.replace(".apk", "-unaligned.apk");
}
output.outputFile = new File(apk.parentFile, newName);
logger.info("INFO: Set outputFile to "
+ output.outputFile
+ " for [" + output.name + "]");
}
}
}
