Error:execution failed for task ':app:transformclasseswithdexfordebug'

Question

Problem :

I am new to Android Programming. I have started working on it recently. Now I am facing below error message.

Error:Execution failed for task ':app:transformClassesWithDexForDebug'. com.android.build.transform.api.TransformException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/usr/lib/jvm/java-8-oracle/bin/java'' finished with non-zero exit value 1

I think above error is caused because I have added too many Gradle dependencies, but all those dependencies are important for my project.

Have anybody faced this issue?

I have faced this problem. I can help you in fixing your problem.

Your Android application files always have the executable bytecode files which are in the form of the Dalvik Executable or DEX files, these files have the compiled code which is used to run your app. Now Dalvik Executable specification is limiting a total number of methods those can be referenced within your single DEX file to 65,536 including your Android framework methods and library methods and also the methods in your own code. To avoid this limit it requires you to configure your app build process such as to be able to  generate more than one your DEX file it is known as a multidex configuration.

So you must format your code with the help of libraries to remove the excess classes and also not to exceed the limit methods. Then you need to Sync Gradle in AndroidStudio and just check if it runs
