but when add gradle, message:

a problem occurred configuring project ':mymodule'. not resolve dependencies configuration ':mymodule:_debugcompile'.    not find com.android.support:design:22.2.0.      searched in following locations:          https://jcenter.bintray.com/com/android/support/design/22.2.0/design-22.2.0.pom          https://jcenter.bintray.com/com/android/support/design/22.2.0/design-22.2.0.jar          file:/d:/development/android/sdk/extras/android/m2repository/com/android/support/design/22.2.0/design-22.2.0.pom          file:/d:/development/android/sdk/extras/android/m2repository/com/android/support/design/22.2.0/design-22.2.0.jar          file:/d:/development/android/sdk/extras/google/m2repository/com/android/support/design/22.2.0/design-22.2.0.pom          file:/d:/development/android/sdk/extras/google/m2repository/com/android/support/design/22.2.0/design-22.2.0.jar      required by:          myproject:mymodule:unspecified 

i tried updating android sdk date:

so why can't com.android.support:design:22.2.0 resolved?

this gradle:

apply plugin: 'com.android.application'  android {     compilesdkversion 21     buildtoolsversion "21.1.2"      defaultconfig {         applicationid "de.bla.myproject"         minsdkversion 19         targetsdkversion 22         compileoptions {             sourcecompatibility javaversion.version_1_7             targetcompatibility javaversion.version_1_7         }     }      buildtypes {         debug {             debuggable true         }         release {             minifyenabled false             proguardfiles getdefaultproguardfile('proguard-android.txt'), 'proguard-rules.txt'         }     } }  dependencies {     compile project(':androidcircularcrop_lib')     compile 'com.google.code.gson:gson:2.2.4'     compile 'com.android.support:appcompat-v7:22.0.0'     compile 'com.google.android.gms:play-services:+'     compile 'com.android.support:design:22.2.0'     compile files('libs/eventbus-3.0.0-beta1.jar')     compile files('libs/mpandroidchartlibrary-2-1-0.jar')     compile files('libs/picasso-2.4.0.jar')     compile files('libs/youtubeandroidplayerapi.jar') } 

looking @ build file, set target , compile sdk same number. appcompat lib part of sdk when using 22.x.x support lib, goning need @ least 22 sdk ensure compatibility, let alone finding lib. arkadiy suggested recommended use latest build-tools , gradle version compatible android studio.
