For me, it was because the layout was using android:theme="@style/AppTheme" in parent Linear Layout. The App theme was defined as:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="actionBarTheme">@color/colorAccent</item>
        <item name="android:textColorPrimary">@color/white</item>
        <item name="android:textColorHint">@color/white</item>

I removed it and everything worked fine.

It might be cause of using high resolution drawable resources.check out drawable file resolutions.

I had the same problem,

problem was that I used a DrawerLayout and that my minSDK was set to below 14. changing that fixed the problem. The android support and appcompat packages for some reason allow you to use the DrawerLayout, but the DrawerLayout definitions for layouts are missing.

changing the minSDK to 14 fixed the issue.

All your @dimens should be defined

for example

<resources>
    <!-- Default margins, per the Android Design guidelines. -->
    <dimen name="activity_horizontal_margin">16dp</dimen>
    <dimen name="activity_vertical_margin">16dp</dimen>
</resources>

You might have added those in for example these folders

  • values-sw600dp
  • values-sw600dp-land
  • values-v19
  • values-xxhdpi

Or any other folder of course where they could belong
But don't forget that those also have to be in

  • values

They have to be also defined there

if that isn't the problem try to create a value-XXXX folder for every layout-XXXX folder you have

  • layout-xhdpi
  • values-xhdpi

And

  • layout-large
  • values-large

for example
