I am making a simple video call app by using Jitsi Android SDK after completion when i build my signed APK its size is too big i.e, 101 MB when i check that apk it shows the type **.nox apk**.

Another problem is when i tried to install that 101MB apk into Mobile it says **App Not Installed**
for this i checked mobile settings **Unknown Sources** after that it stick to the same message (App not installed).

this is my App's **build.gradle(app)** file
