Question

I have been trying from last 2 days to generate the secure signed apk for my application but still not get any success in it.

I have check so many answers of StackOverflow and tried every solution but nothing worked for me. So here i am if anyone can help me out it will be really grateful and will really appreciate the help.

Below is the error which i am getting while generating the Secure signed apk.

EDITED:

I have some changes in my proguard file and now i am getting below error

Please help me out any help will be appreciated.

Thanks.

Answer 1

I have resolved my issue by adding the below two lines in my proguard.cfg file.

-keep class android.support.v4.** { ; }
-dontwarn android.support.v4. *

Answer 2

use

-dontwarn android.support.v4.**

another try:

download the lates proguard ( i downloaded 4.9) and changes the lib folder

another another try:

you can use a standard proguard. for example see here

Recently I also faced several problems and planning to learn progruard mechanismn in depth. But at present I have very little idea about this. But the previous three solution saves me several time
