Answer 1

You are getting

Removed unused resources: Binary resource data reduced from 741KB to 402KB: Removed 45%
Note: If necessary, you can disable resource shrinking by adding
android {
    buildTypes {
        release {
            shrinkResources false
        }
    }
}
:app:validateExternalOverrideSigning
:app:packageRelease FAILED
Error:Execution failed for task ':app:packageRelease'.

Resource shrinking works only in conjunction with code shrinking.

minifyEnabled is an Android tool that will decrease the size of your application when you go to build it .

android {

    buildTypes {
        release {
            shrinkResources true // This must be first 
            minifyEnabled true   // This must be after shrinkResources 
            proguardFiles getDefaultProguardFile('proguard-android.txt'),
                    'proguard-rules.pro'
        }
    }
}

If you haven't already built your app using minifyEnabled for code shrinking, then try that before enabling shrinkResources, because you might need to edit your proguard-rules.pro file to keep classes or methods that are created or invoked dynamically before you start removing resources.

Advice

Use latest version

compileSdkVersion 25
buildToolsVersion '25.0.1'
targetSdkVersion 25
compile 'com.android.support:appcompat-v7:25.1.0' // set other 25.1.0

NOTE

YouTubeRecyclerViewFragment.java uses or overrides a deprecated API.

Use Alternate Latest Version .
