Why are you adding libs? You are using Android Studio. Post your code and `build.gradle`. — Jared Burrows, Apr 01 '15 at 14:59
You need `Clean Project`, check out [here](http://stackoverflow.com/questions/17054000/cannot-resolve-symbol-r-android-studio) — bjiang, Apr 01 '15 at 16:48
And you may try to change `import info.androidhive.slidingmenu.R;` to `import com.iremember.kiet.R;` — bjiang, Apr 01 '15 at 16:58

Step 1(optional but helpful):

This is Java and not C or C++, stop trying to memorize the imports.

You are using Android Studio which is based off Intellij, turn on Optimize Imports: https://www.jetbrains.com/idea/help/optimizing-imports.html

Step 2:

Sync and Clean your project.

Step 3:

Without a doubt, you need to target the latest libs, get these from your SDK Manager:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22 // <-- was 18
    buildToolsVersion "22.0.0" // <-- was 21.1.2

    defaultConfig {
        applicationId "info.androidhive.slidingmenu"
        minSdkVersion 11
        targetSdkVersion 22 // <-- was 17
    }

    buildTypes {
                 // <-- debug is debuggable by default
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile 'com.android.support:support-v4:22.0.0' // <-- was 18
    compile 'com.android.support:appcompat-v7:22.0.0' // <-- was 21.0.3
    compile 'com.google.android.gms:play-services:6.5.87'
}
