I have two android project with same source code only app icon change in both app. But i don't have use product flavor. now i need to merge source code and use product flavor. so it is possible?
What you are looking for has been answered here, basically what you need to do is to create a folder structure that mirrors the main->res->mipmap structure replacing main with your flavour name like this:
-src
-main
-res
-app_one
-res
-mimap-*
-ic_launcher.png
-app_two
-res
-mimap-*
-ic_launcher.png
EDIT
After merging the source code of the 2 projects you need to create 2 different product flavours in your gradle configuration and use the manifest placeholders for things like the app name and package:
productFlavors {
app_one {
applicationId "xxx.yyy.zzz"
}
app_two {
applicationId "aaa.bbb.ccc"
}
}
And in your manifest:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="${applicationId}">
If the code content is the same you shouldn't have any issue, just select the right buildVariant and keystore when preparing the release apk.
