Eclipse中的appcompat_v7错误

Question

I am a newbie at android development.I created a new project but along with it appcompat_v7 also got created.Now my project does not run since appcompat_v7 has errors. The error is only in the appcompat_v7-> res-> values-v21-> style_base.xml on the following line

<style name="Base.Widget.AppCompat.ActionButton"
           parent="android:Widget.Material.ActionButton">
  </style>

with the description

Error retrieving parent for item: No resource found that matches the given name 'android:Widget.Material.ActionButton'

I have tried cleaning and rebuilding the project but the error persists.How do I fix this?

Here is the appcompat_v7 -> res -> values-v21 -> styles.xml This file is the one with the error on line 75: Error:

<style name="Base.Widget.AppCompat.ActionButton"
           parent="android:Widget.Material.ActionButton">
    </style>

This is the file

Answer 1

Check you Build targets in both your project and appcompat. Your project must not be less than the target of appcompat which, I think needs SDK 10 or newer:

In Eclipse go to Project->Properties->Android (Project Build Target)

Answer 2

Somebody else had the same problem, you need to install Java 1.8

See this link: https://stackoverflow.com/a/26642124/2767703

Answer 3

when Android Lollipop has launched, eclipse and sdk manager also upgraded but

SDK 5.0(Lollipop) has issues about v7 (appcompat, cardview ... ) - doesn't found resource or matched.

or this will help you

Answer 4

To resolve this issue,

1. Right Click on appcompat_v7 library and select Properties
2. Click on Android Option,
3. Set Project Build Path as Android 5.0 (API level 21)
4. Apply Changes.
5. Go to file under appcompat_v7 library,
6. Set the project target as : target=android-21
7. Clean + Build appcompat_v7 library and your projects

See here

Answer 5

Right-Click on the appcompat project folder and open "properties". Go to "Android" section and check "Android 5.0" as the project build target apply it and enjoy :)

Answer 6

Hope this approach will help you.

Update the project.properties file of appcompat v7 , which has: target=android-19 to target=android-23 . Always target to upper version .
