Re: import asmack source to android studio,but run App failed.

I fixed the problem. the reason is that all files of org.jivesoftware.smack and org.jivesoftware.smacx folders won't be packaged when gradle build.

I added some code in build.gradle to fix it.

task preBuild(overwrite:true) {    copy {        from('src/main/java/org.jivesoftware.smack') {            include "**"        }        into('build/intermediates/classes/debug/org.jivesoftware.smack')    }    copy {        from('src/main/java/org.jivesoftware.smack') {            include "**"        }        into('build/intermediates/classes/release/org.jivesoftware.smack')    }    copy {        from('src/main/java/org.jivesoftware.smackx') {            include "**"        }        into('build/intermediates/classes/debug/org.jivesoftware.smackx')    }    copy {        from('src/main/java/org.jivesoftware.smackx') {            include "**"        }        into('build/intermediates/classes/release/org.jivesoftware.smackx')    }
}
