Android error: AAPT: error: resource color/colorPrimary not found

Question

I upgraded my project ( Ionic Framework ) from Android to AndroidX. After that, my project started throwing errors while rebuilding. It is giving "AAPT: error: resource color/colorPrimary (aka io.aide.aide:color/colorPrimary) not found." from file "{Project}\android\app\src\main\res\values\styles.xml".

Here is my styles.xml file

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

    <style name="AppTheme.NoActionBar" parent="Theme.AppCompat.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
        <item name="android:background">@null</item>
    </style>


    <style name="AppTheme.NoActionBarLaunch" parent="AppTheme.NoActionBar">
        <item name="android:background">@drawable/splash</item>
    </style>
</resources>

The folder of styles.xml is as below

In the below post, they suggested to create a color file. Error:(387, 5) error: resource color/colorPrimary (aka com.example.kubix.r3vir3dv3:color/colorPrimary) not found

I am beginner and I do not know what should be in the color file.

Can any one give me any suggestions to overcome this problem?

can you share colors.xml file?

In your project, you need to create color.xml file

Right click on values > New > Values Resource File > Enter File Name "color.xml"

Path:

 res/values/color.xml

This is how your color.xml will look like:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="colorPrimary">@color/blue_1</color>
    <color name="colorPrimaryDark">@color/blue_1</color>
    <color name="colorAccent">@color/blue_5</color>

    <color name="blue_1">#00101f</color>
    <color name="blue_5">#0078ff</color>

</resources>

Thank you so much. It solved my problem. Finally, I am able to upgrade my project to AndroidX and build it without errors.

for me, the color.xml had to go straight to /values folder

You need to define the color resources in res/values/colors.xml to avoid the error.

Example :

for @color/colorPrimary write the following code in res/values/colors.xml <color name="colorPrimary">#3F51B5</color>
for @color/colorPrimaryDark write the following code in res/values/colors.xml <color name="colorPrimaryDark">#303F9F</color>
for @color/colorAccent write the following code in res/values/colors.xml <color name="colorAccent">#FF4081</color>
