apkanalyzer

The command-line version of APK Analyzer provides immediate insight into thecomposition of your APK after the build process completes, and allows you tocompare differences between two APKs. By using APK Analyzer, you can reduce thetime you spend debugging issues with DEX files and resources within your app andreduce the size of your APK.

apkanalyzer is included in the Android SDK Tools package and located atandroid_sdk/tools/bin/apkanalyzer.Alternatively, you can access the APK Analyzer tool withinAndroid Studio as described inAnalyze Your Build with APKAnalyzer.

Syntax

  1. apkanalyzer [global-options] subject verb [options] apk-file [apk-file2]

The subject is what you want to query and can be the entire APKor a part of the APK. A subject can be any one of the following.

  • apk: Analyze APK file attributes such as application ID, version code, and version name.
  • files: Analyze the files inside the APK file.
  • manifest: Analyze the contents of the manifest inside the APK file.
  • dex: Analyze the DEX files inside the APK file.
  • resources: View text, image, and string resources.
    The verb is what you want to know about the subject. The subjects,verbs, and their options are described in Commands.

Every command requires that you specify an APK file. Only theapk compare command requires that you specify a second APK.You can shorten every option as long as the option is unambiguous. For example,the —human-readable global option can be shortened to-h. The following example analyzes the apk (subject)to get its file-size (verb), and then prints the file size in ahuman-readable format (-h option):

  1. apkanalyzer -h apk file-size myapk.apk

Global options

Option Description
—human-readable Prints sizes in human-readable format.
