No Resource Identifier Found For Attribute 'roundicon' In Package 'android'

I'm trying to compile my Project,but in there is some error Android manifest.xml

Solution 1:

roundIcon is an attribute that was first introduced for Android Nougat 7.1 (API level 25), therefore you have two available options based on the type of device you're targeting:

• If you're building an app specifically for Android 7.1 or above, ensure that minSdkVersion and targetSdkVersion are set to 25 in your app's build.gradle:

---

defaultConfig {
    minSdkVersion 25
    targetSdkVersion 25
}

---

• Alternatively, if you want to target older API levels, you will need to remove android:roundIcon from your manifest and only use android:icon.

Solution 2:

I removed android:roundIcon from my manifest, but when compiling my project with API 24, the android:roundIcon property is still added to the AndroidManifest.xml.

In order to resolve my problem, I had to update my API to version 25 and set comileSdkversion to 25.

Solution 3:

roundIcon is an attribute that was first introduced for Android O (8.0). So you have to change the app compile SDK version.

Solution 4:

As already answered earlier, roundicon was first introduced in API Level 25. If you want to maintain a lower API level without increasing to >= 25 then

go to the mipmap directory and delete the subdirectory "ic_roundicon" with all its files

delete @res/mipmap/ic_roundicon
