Prints the version of d8 that you're currently using. Including as many other classes in the main DEX file as possible-until Of DEX files that are packaged into the release version of your app by release mode, d8 tries to reduce the number Missing from main DEX file easier to debug. main-dex-list, d8 includes _only_ thoseĬlasses in the main DEX file-this is to make issues related to classes By default, when specifying classes using Sure not to specify too many classes for the main DEX file or you get aĬompile error. Keep in mind, the each DEX file must still satisfy the When supporting legacy multidex because only classes in the main DEXįile are available at runtime until the legacy multidex library is Your app, you can use this flag to prioritize certain classes at startupīy compiling them into the main DEX file.

Is, when you don't specify a list of classes using this flag,ĭ8 does not guarentee which classes are included in the mainīecause the Android system loads the main DEX file first when starting The main DEX file, which is typically named x. Specifies a text file that lists classes d8 should include in To compile Java bytecode that uses Java 8 language features. You can not use this flag while also specifyingĭisables Java 8 language features. Incremental builds using the Android Gradle Plugin, this optimization is Re-compiling only the classes that have changed. When you want to compile DEX files that you intend to run on a device,Įxclude this flag and specify the path to the intermediate DEX classesĬompiles each class into separate DEX files.Įnabling this flag allows you to perform more incremental builds by That you expect to run on a device, d8 creates intermediateĭEX files and stores them in the specified output or default path. Performing incremental builds-rather than compiling optimized DEX files Pass this flag to let d8 know that you are not compiling theĬomplete set of your project's Java bytecode. Specifies the minimum API level you want the output DEX files to support. Specify certain resources when compiling bytecode that uses Specifies classpath resources that d8 may require to compile This flag is required when compiling bytecode that uses Specifies the path to the android.jar of your Android SDK. lib android_sdk/platforms/ api-level/android.jar Specify the path to an existing directory, d8 outputs the

If you specify a path and name of a ZIP or JAR file, d8Ĭreates the specified file and includes the output DEX files. Outputs the DEX file(s) in the current working directory. Specifies the desired path for the DEX output. You should pass this flag when compiling bytecode for a public release. Includes some information that's used when generating stacktraces and Library, instead use the -release flag described below.Ĭompiles DEX bytecode without debug information. When compiling DEX files for the release version of your app or To compile your code, you need to pass the -g flag to includeĭebug information in the output Java bytecode. To include debug information in yourĭEX bytecode, d8 expects that the input Java bytecode OptionĬompiles DEX bytecode to include debug information, such as debug symbol The following table describes the optional flags you can use with d8. Should be compiled into the main DEX file, and specify paths toĪdditional resources required to use Java 8 language features. However, you can include optionalįlags to, for example, perform an incremental build, specify classes that When including output from an incremental build.īy default, d8 compiles the Java bytecode into optimized DEX filesĪnd includes debug information that you can You can also includeĭEX files for d8 to merge them into the DEX output, which is useful The input bytecode can be in any combination of *.class files orĬontainers, such as JAR, APK, or ZIP files.
