Default AndroidManifest contains android:configChanges value introduced in high api level, which will break the compile against lower api level

https://developer.android.com/guide/topics/manifest/activity-element#config
Density is introduced api level 24.

Confirmed that building with default AndroidManifest in 5.12.11 using android-18 or in 5.15.5 using android-21 will break. The workaround is to create the android template and modify AndroidManifest.xml manually by removing "density" from the android:configChanges tag.

Note: when compile in 5.15.5 using android -21, another extractNativeLibs tag also needs to be removed
