Error: package android.hardware.camera2 does not exist OpenCV

Question

I'm trying to add the OpenCV module to a project, but I'm not able to solve some gradle issues. Here is my app.gradle file:

apply plugin: 'com.android.application'  android {     compileSdkVersion 17     buildToolsVersion "23.0.2"      defaultConfig {         applicationId "com.sveder.cardboardpassthrough"         minSdkVersion 8         targetSdkVersion 21     }      buildTypes {         release {             minifyEnabled false             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'         }     } }  dependencies {     compile 'com.android.support:support-v4:18.0.0'     compile files('libs/cardboard.jar')     compile project(':openCVLibrary') } 

Here's the build.gradle file of the OpenCV (3.0) module:

apply plugin: 'com.android.library'  android {     compileSdkVersion 17     buildToolsVersion "23.0.2"  defaultConfig {     minSdkVersion 8     targetSdkVersion 21 }      buildTypes {         release {             minifyEnabled false             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'         }     } } 

As you can see, my app and OpenCV gradle files match, and yet whenever I try to build the project I have the error error: package android.hardware.camera2 does not exist. What am I doing wrong?

Thanks in advance.

Change compileSdkVersion 17 to minimum 21 (recommended latest). Because android.hardware.camera2 was added in API 21.
