Android Studio API 22 gives an error Unfortunately, “App Name” has stopped working after successful build

Question

I created material design in Android Studio version 1.2.1.1 API 22. Build is successful with zero errors and zero warning. When I run the app it gives runtime error "Unfortunately, “App Name” has stopped working".

My styles.xml

<resources>

    <style name="MyMaterialTheme" parent="MyMaterialTheme.Base">

    </style>

    <style name="MyMaterialTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="android:windowNoTitle">true</item>
        <item name="windowActionBar">false</item>
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:textColorPrimary">@color/textColorPrimary</item>
        <item name="android:windowBackground">@color/windowBackground</item>
    </style>

</resources>

Updated styles.xml -

<resources>

    <style name="MyMaterialTheme" parent="MyMaterialTheme.Base">

    </style>

    <style name="MyMaterialTheme.Base" parent="Theme.AppCompat">
        <item name="windowNoTitle">true</item>
        <item name="windowActionBar">false</item>
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:textColorPrimary">@color/textColorPrimary</item>
        <item name="android:windowBackground">@color/windowBackground</item>
    </style>

</resources>

This is my logcat:

I have tried every possible solution. Still unable to run the app. Please help.

I have tried making changes in styles.xml as per the existing answer but no luck so far. — Rishika Kapur, May 28 '15 at 09:13

Try removing the android prefix in <item name="android:windowNoTitle">true</item> i.e replace it with <item name="windowNoTitle">true</item>.

Also replace <style name="MyMaterialTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar"> with <style name="MyMaterialTheme.Base" parent="Theme.AppCompat"> , the Light.DarkActionBar part is unnecessary as you are specifying windowActionbar as false and windowNoTitle as true and setting action bar in activity.

Also one more thing, ActionBarActivity is deprecated in revision 22.1.0 of the Support Library and so AppCompatActivity should be used instead of ActionBarActivity. This has nothing to do with issue, but is just a suggestion.

Hope this will help you resolve the issue as all other parts of your code look ok.

Thank you so much @AlokNair. App is running fine now. However a little issue there is rendering problems with `activity_main.xml` - `Rendering Problems java.lang.NullPointerException at com.android.layoutlib.bridge.impl.RenderSessionImpl.isThemeAppCompat(RenderSessionImpl.java:1203) at com.android.layoutlib.bridge.impl.RenderSessionImpl.findStatusBar(RenderSessionImpl.java:1066)` – Rishika Kapur May 28 '15 at 09:55

Try changing app/src/main/res/values/styles.xml from:

<resources>
    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
    </style>
</resources>

to:

<resources>
    <!-- Base application theme. -->
    <style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
    </style>
</resources>
