Ionic Android emulator error INSTALL_FAILED_OLDER_SDK
So, basically it means that the installation has failed due to having an older SDK version than the targetSdkVersion specified in your app (it's a Gradle issue). Just edit the AndroidManifest.xml file and add the following code:
<uses-sdk android:minSdkVersion="19" android:targetSdkVersion="14"/>

After days looking for the solution, that's it.
Works fine for me!
