I am trying to understand why the Android SDK needs the JDK.
Thanks
The general process for a typical build is outlined below:
- The Android Asset Packaging Tool (aapt) takes your application resource files, such as the AndroidManifest.xml file and the XML
files for your Activities, and compiles them. An R.java is also
produced so you can reference your resources from your Java code.- The aidl tool converts any .aidl interfaces that you have into Java interfaces.
- All of your Java code, including the R.java and .aidl files, are compiled by the Java compiler and .class files are output.
- The dex tool converts the .class files to Dalvik byte code. Any 3rd party libraries and .class files that you have included in your
project are also converted into .dex files so that they can be
packaged into the final .apk file.- All non-compiled resources (such as images), compiled resources, and the .dex files are sent to the apkbuilder tool to be packaged into an .apk file.
- Once the .apk is built, it must be signed with either a debug or release key before it can be installed to a device.
- Finally, if the application is being signed in release mode, you must align the .apk with the zipalign tool. Aligning the final .apk decreases memory usage when the application is running on a device.
From here
The Android SDK uses the JDK to compile your .java
files to .class
bytecode.
