Possible to hide used third party libraries files in .aar file?

    I am developing an Android library (APIs). As part of this, I am using some other third party library (free) too. I will provide the detailed documentation to the developers who want to use my APIs also. When developer want to use my library, the developer will import my library .aar file and use the APIs. Eventhough I am providing .aar file, the developer is able to see the source code of my library. I am aware about pro-guard. I didn't want to expose my source code to the end developers. At lease, I didn't want to expose to the outside people about the third party library that I am using. Can anybody suggest me how to do this?

    Thanks in advance.

    The best you can do is obfuscate your source code, or bytecode, using a tool such as ProGuard.

    Thank you for your Suggestion ,

    I did changes but i am facing some issue please look into my code.
    buildTypes {
    release {
    minifyEnabled true // shrink
    useProguard false // obfuscate
    proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    debug {
    minifyEnabled true // shrink
    useProguard true // don't obfuscate

    proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
