Android Question Problem after upgrading SDK files.

Use a real device. The emulator is slow and unreliable

Emulator is working nicely now when using intel atom based emulator.

Black screen continues when installing it to the real phone.

Android Support Library, revision 22.1.1

It is something related to appcompat ??

Yes I got it sorted... because I use appcompat and support library was updated:

From appcompat thread:

1. Copy the android-support-v4.jar and android-support-v7-appcompat.jar which can be found in <Android SDK-Base>\android-sdk\extras\android\support\v7\appcompat\libs to your custom libs folder

1. Important Information about Support library version 22.1 and up
   If you upgrade to the support library v22.1 or above you may run into the following exception:
   
   Causedby: java.lang.IllegalArgumentException:AppCompat does not support the current theme features
   at android.support.v7.app.AppCompatDelegateImplV7.ensureSubDecor(AppCompatDelegateImplV7.java:360)
   at android.support.v7.app.AppCompatDelegateImplV7.setContentView(AppCompatDelegateImplV7.java:246)
   at android.support.v7.app.AppCompatActivity.setContentView(AppCompatActivity.java:106)
   This is because AppCompat in this version (and above) is more strict than before. I think it happens only if you set a ToolBar as ActionBar. The solution is to use a NoActionBar theme as a parent in your custom theme or disable the ActionBar in the theme:
   
   1. Use a NoActionBar theme like Theme.AppCompat.NoActionBar
   
   2. Use something like this in your Theme:
   
   Code:
   <?xml version="1.0" encoding="utf-8"?>
   <resources>
   <style name="MyAppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
   <item name="colorPrimary">#FF9800</item>
   <item name="colorPrimaryDark">#F57C00</item>
   <item name="colorAccent">#FFA726</item>
   <item name="windowNoTitle">true</item>
   <item name="windowActionBar">false</item>
   </style>
   </resources>
   This should fix the issue.
