Ionic2 - Android emulator does not show the app

Ionic Framework ionic-v3
1

I’m not able to see my app in my android emulator.

if I run cordova build android I get a successful message:

:mergeDebugJniLibFolders
:transformNative_libsWithMergeJniLibsForDebug :processDebugJavaRes
UP-TO-DATE :transformResourcesWithMergeJavaResForDebug
:validateDebugSigning :packageDebug :zipalignDebug :assembleDebug
:cdvBuildDebug

BUILD SUCCESSFUL

Total time: 23.015 secs Built the following apk(s):
C:/Dev/myProject/platforms/android/build/outputs/apk/android-debug.apk

But as soon as I run ionic run android or ionic emulate android, the emulator starts, but I cannot see my app there.

What am I missing?

EDIT:

Problem is not solved, but this might help:

I receive a few warnings:

emulator:
WARNING: Increasing RAM size to 1024MB

emulator:
WARNING: VM heap size set below hardware specified minimum of 48MB

emulator:

The problem is SOLVED!

I’m using MathJax directive and it seemns like MathJax is not supported by Chromium. It is a MathJax issue!

After removing MathJax reference, it worked fine!
