Android Studio implements code obfuscation, androidstudio

1, added in build. grandle, where rules are written in the proguard-rules.pro, you can also customize a file, replace it, such as eclipse commonly used proguard-project.txt

buildTypes {  release {    signingConfig signingConfigs.release    minifyEnabled true    proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'  }}

2, add the following code in the proguard-rules.pro, basically covering all

-Optimizationpasses 5 # specify the compression level of the code-dontusemixedcaseclassnames # whether to use case-insensitive mixture-dontpreverify # Whether to perform pre-check-verbose # Whether to log-optimizations during obfuscation!

3. When obfuscation code is implemented through Android Studio, the jar files in the lib directory have been added to the packaging script by default. Therefore, you do not need to manually add the jar files again. Otherwise, "java. io. IOException: The same input jar is specified twice "error.
