• for googleplay without ads
• for googleplay without ads , customjarsdk
• for amazonstore ads
• for amazonstore ads , customjarsdk
• for amazonstore without ads
• for amazonstore without ads , customjarsdk
• for samsungapps ads
• for samsungapps ads , customjarsdk
• for samsungapps without ads
• for samsungapps without ads , customjarsdk

it quite difficult answer question. depends resources different in flavor.

currently you can't extend flavors or merge them.

however can use use tips improve project.

for example can use common sourceset resources different flavors.

something that:

+ app // module |- src    |- common // shared srcdir       |- java    + flavor1       |- java    + flavor2       |- java    + flavor3    + flavor4 

then can define somenthing this:

 sourcesets {                     flavor1.java.srcdir 'src/common/java'         flavor2.java.srcdir 'src/common/java'         flavor3.java.srcdir 'src/common/java'     } 

in case should evaluate if flavors:

• for googleplay ads
• for googleplay ads , customjarsdk
• for googleplay without ads
• for googleplay without ads , customjarsdk

can use common block:

 sourcesets {             flavor1.java.srcdir = ['src/common/java', 'src/flavor1/java']             flavor2.java.srcdir = ['src/common/java', 'src/flavor2/java']             flavor3.java.srcdir = ['src/common/java', 'src/flavor3/java']         } 

each flavor can use same sourceset defined in flavor.
somenthing that:

flavor2{         java.srcdirs = sourcesets.flavor1.java.srcdirs         res.srcdirs = sourcesets.flavor1.res.srcdirs         resources.srcdirs = sourcesets.flavor1.resources.srcdirs         aidl.srcdirs = sourcesets.flavor1.aidl.srcdirs         renderscript.srcdirs = sourcesets.flavor1.renderscript.srcdirs         assets.srcdirs = sourcesets.flavor1.assets.srcdirs     } 

also each flavor can define multiple resource folders. instance:

android.sourcesets {    flavor1.res.srcdirs = ['src/main/res', src/main/res2'] }
