Resource Not found exception while opening Unity Project in Android studio

Since Google warned us to provide support to 64-bit architecture, I am migrating my existing Unity Project from version Unity 5.6.6f to Unity 2018.4.1f

Upon running my project app crashes with log,

2019-06-02 20:08:27.869 14987-14987/com.example.myapplication:unityplayer E/AndroidRuntime: FATAL EXCEPTION: main Process: com.example.myapplication:unityplayer, PID: 14987 java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.myapplication/com.example.myapplication.UnityActivity}: android.content.res.Resources$NotFoundException: String resource ID #0x0 at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2747) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2808) at android.app.ActivityThread.-wrap12(ActivityThread.java) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1541) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:165) at android.app.ActivityThread.main(ActivityThread.java:6375) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:912) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:802) Caused by: android.content.res.Resources$NotFoundException: String resource ID #0x0 at android.content.res.Resources.getText(Resources.java:347) at android.content.res.MiuiResources.getText(MiuiResources.java:97) at android.content.res.Resources.getString(Resources.java:393) at com.unity3d.player.UnityPlayer.a(Unknown Source) at com.unity3d.player.UnityPlayer.(Unknown Source) at com.example.myapplication.UnityActivity.onCreate(UnityActivity.java:52) at android.app.Activity.performCreate(Activity.java:6845) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1119)

What i have done is,

I have changed the scripting back-end configuration to IL2CPP to support 64-bit architecture. After exporting, I have pasted the Library folder, Asset folder and JniLibs folder contents (which I got from exported Unity Android project) to my Android project respective folders.

Can anyone please help me to sort out this issue.
