Bump minSDK to API 15

[nhachicha]

We need to bump theminSDK to 11 as the lib is not usable under API < 11

createAllFromJson target an API 11 which is fine to avoid compile/install error under lower SDK but the implementation of Dalvik on lower API fails when the dependencies fails during classloading
(even if this deps is not used). This issue is highlighted by CommonWare
here

Huh? The lib does work on API < 11, the referenced post said that API level 4 didn't allow it but API level 8 did. Otherwise I'm sure this would have come up a long time ago.

Don't forget, API level 8 is Froyo. The SO question worked for him on Froyo.

Here is a sample project that demonstrate the issue. https://www.dropbox.com/s/wnkgbrfpzxu9hr6/RealmHelloWorld.zip?dl=0

Trying to run this under Genymotion 2.3.7 API 10 will fail

I'm pretty sure we could run 0.82.2 which already had the JSON API on a Genymotion 2.3.7 emulator.

I think this issue is bogus, and the issue is the armeabi support: #3506

The API 10 crash is because of #3726 . And I am fixing it. Close this now.

Although with #3726 fix, our tests don't run well on API 10 devices. It could be another issue than #3726. Reopen this for tracking it.

API 9 is now gone from https://developer.android.com/about/dashboards/index.html
API 10 is still at 1%, after that we can bump to 15

This is part of #6460

With NDK 21 MinSdk is now 16
