3、build tools

• aapt	android asset packaging tool, take resources and Androidmanifest.xml and compile them, provide R.java.
  aidl	converts any .aidl interfaces that you have into Java interfaces, output .java
  javac	compile java code, output .class
  dex	converts the .class files to Dalvik byte code
  apkbuilder	package non-compiled resources (images), compiled resources, and the .dex files into an .apk file
  jarsigner	sign the apk with a debug or release key
  zipalign	Aligning the final .apk decreases memory usage
  proguard	optimizes, and obfuscates your code by removing unused code and renaming classes, fields, and methods with semantically obscure names
  dex-preopt	input the .jar or .apk, output .odex
  dexopt	optimize dex with byte-swapped and struct-aligned
  zip/unzip	compress and uncompress tool
  jar	java package tool
