I'm using Gradle to compile my Android project:
buildTypes {
release {
signingConfig signingConfigs.release
applicationVariants.all { variant ->
def file = variant.outputFile
def fileName = file.name
fileName = fileName.replace(".apk", "-renamed.apk")
variant.outputFile = new File(file.parent, fileName)
}
}
}
Not all output files are renamed, it always skips 1 file. Why?
myapp-debug-unaligned-renamed.apk <-renamed, OK!
myapp-release.apk <-NOT renamed, WRONG!
myapp-release-unaligned-renamed.apk <-renamed, OK!
I solved using this code:
buildTypes {
release {
signingConfig signingConfigs.release
}
applicationVariants.all { variant ->
def apk = variant.packageApplication.outputFile;
def newName = apk.name.replace(".apk", "-renamed.apk");
variant.packageApplication.outputFile = new File(apk.parentFile, newName);
if (variant.zipAlign) {
variant.zipAlign.outputFile = new File(apk.parentFile, newName.replace("-unaligned", ""));
}
}
}
The block applicationVariants.all {...}
is now outside the release {...}
block.
I think variant.zipAlign.outputFile
makes the difference.
There should be 3 output APK files when using your build.gradle configuration: debug unsigned unaligned, release signed aligned and release signed unaligned. There are two variables for applicationVariant
to deal with output files: outputFile and packageApplication.outputFile, the former is used for zipalign and the later is used in general case.
So the proper way to rename all the files will be like this:
android.applicationVariants.all { variant ->
if (variant.zipAlign) {
def oldFile = variant.outputFile;
def newFile = oldFile.name.replace(".apk", "-renamed.apk")
variant.outputFile = new File(oldFile.parent, newFile)
}
def oldFile = variant.packageApplication.outputFile;
def newFile = oldFile.name.replace(".apk", "-renamed.apk")
variant.packageApplication.outputFile = new File(oldFile.parent, newFile)
}
