I want to update my app, but when I try to generate a signed apk, I receive an error with these messages:

Warning:warning: Cannot find annotation method 'value()' in type 'GuardedBy': class file for javax.annotation.concurrent.GuardedBy not found

Error:Error converting bytecode to dex: Cause: com.android.dex.DexException: Multiple dex files define Lbolts/AppLink$Target;

Try multiDexEnabled true like this:

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"

        multiDexEnabled true
    }
}

EDIT : And if you don't know which part to exclude just add below code to your build.gradle just below defaultConfig:

packagingOptions {
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/license.txt'
    exclude 'META-INF/notice.txt'
}

Why need to enable multiDex? – LKH Apr 11 '16 at 05:07
As you have used Facebook SDK the number of methods in your project may be more than 65,000. `multiDex` solved my problem so i referred you the same. – Janki Gadhiya Apr 11 '16 at 05:09
If I enable it, I need to use multiDex library and do some config too right? – LKH Apr 11 '16 at 05:24
library for multiDex?? sorry, i haven't heard this before. I think there is no library for `multiDex`. – Janki Gadhiya Apr 11 '16 at 05:26
I'll test it and tell you – LKH Apr 11 '16 at 05:33
Yes, it work, but I also need to exclude duplicate library like @Giru Bhai commented – LKH Apr 11 '16 at 08:33
You can use it by excluding duplicate part. as explained in this question. http://stackoverflow.com/a/35550829/6127411 – Janki Gadhiya Apr 11 '16 at 09:20
