Secure your android java codes from decompile or reverse engineering

One Idea, If you implement JAVA 8 library with your android projects, then it is impossible to decompile by any tools available. I will show you how you implement that.

There is 2 types of gradle files:
1. Project's gradle.build and
2. App's gradle.build

For point. 1 you make changes like:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'

        // ADD THIS
        classpath 'me.tatarka:gradle-retrolambda:3.2.5'        

}

Then For point 2, there are some additions are required like:

apply plugin: 'com.android.application'
// ADD THIS
apply plugin: 'me.tatarka.retrolambda'

android {
// ADD THIS
compileOptions {
targetCompatibility 1.8
sourceCompatibility 1.8    }
}

Yupp, thats all. My friend. Your codes are secured from any type of reverse engineering.

Note: Plus point is you can use LAMBDA with your logic now. And addition with
compile 'com.annimon:stream:1.0.9'
You can use JAVA STREAM as well.. ;)
