Build Error with Android Studio

Question

first of this is my first app, and first time using Android Studio, so I am hoping it's just a small thing I don't understand yet.

Here are my error messages;

AGPBI: {"kind":"ERROR","text":"No resource found that matches the given name (at \u0027icon\u0027 with value \u0027@mipmap/ic_launcher\u0027).","sourcePath":"C:\\Users\\Matt\\AndroidStudioProjects\\FirstApp\\app\\build\\intermediates\\manifests\\full\\debug\\AndroidManifest.xml","position":{"startLine":13,"startColumn":23,"startOffset":385,"endColumn":42,"endOffset":404},"original":""} FAILED FAILURE: Build failed with an exception. * What went wrong: Execution failed for task ':app:processDebugResources'. > com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Users\Matt\AppData\Local\Android\sdk\build-tools\21.1.2\aapt.exe'' finished with non-zero exit value 1

This is the code on the Manifest xml:

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.matt.firstapp" > <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name=".MainActivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> </manifest>

With the following error message on line 7; Cannot resolve symbol '@mipmap/ic_launcher' less... (Ctrl+F1) Validates resource references inside Android XML files.

I already have android 21.1.2 installed:

android sdk manager, packages and versions

Thanks for any help!

It would certainly be easier to answer if you could post the content of your AndroidManfiest.xml — Lolo

The Unicode escape notation \u0027 stands for a quote character. Thus, from the error message, it looks like you have something similar to 'icon' = '@mipmap/ic_launcher' somewhere in your AndroidManifest.xml, and I'm guessing it should be more like android:icon="@mipmap/ic_launcher".

this is the line; android:icon="@mipmap/ic_launcher" Cannot resolve symbol '@mipmap/ic_launcher' less... (Ctrl+F1) Validates resource references inside Android XML files

yup. should refer '@drawable/'

@Matthew do you actually have, under app/src/main/res, a set of folders mipmap-mdpi, mipmap-hdpi etc...? At least one of them should have an ic_launcher.png file in it.
