Fork from Google MultiDex
A library for speeding up app launch at the first time when you used google multi dex for compacting some devices which system version code were below 5.0 .
Performance can be increased by 30%-65%.
The default implement of google MultiDex dex was serialization work.
- Extract every classesN.dex from apk
- Fork sub process for doing dex opt for every classesN.dex file
We can split task and work parallel in different thread to optimize MultiDex.install().
Add below code in build.gradle of your app project and nothing to do with java code.
dependencies {
compile 'com.cantalou:multidex:1.0.1'
}
configurations.all {
exclude group: 'com.android.support', module: 'multidex'
}
There three classesN.dex in test apk and every dex contains about 40000+ methods.
