Manifest merger failed : uses-sdk:minSdkVersion 9 cannot be smaller than version L declared in library com.android.support

Question

I have a problem - I imported the project in Android Studio. When I run the project I get the following error:

Error:Execution failed for task ':driverNotes:processDebugManifest'.

Manifest merger failed : uses-sdk:minSdkVersion 9 cannot be smaller than version L declared in library com.android.support:support-v4:21.0.0-rc1

android {
compileSdkVersion 19
buildToolsVersion '19.1.0'
defaultConfig {
    minSdkVersion 9
    targetSdkVersion 19
}

Dependencies in build.gradle:

dependencies {
    compile project(':facebookSDK')
    compile project(':vKOpenAuthActivity')
    compile project(':easyFousquareActivity')
    compile project(':pullToRefresh')
    compile project(':volley') 
    compile 'com.android.support:appcompat-v7:20.+'
    compile 'com.android.support:support-v4:20.+'
    compile 'com.google.android.gms:play-services:+'   
    compile files('libs/commons-codec-1.9.jar')
    compile files('libs/signpost-commonshttp-1.2.1.1.jar')
    compile files('libs/signpost-core-1.2.1.2.jar')
    compile files('libs/twitter4j-core-4.0.1.jar')
    compile files('libs/nineoldandroids-2.4.0.jar')
    compile files('libs/gson-2.2.4.jar')
    compile files('libs/httpclientandroidlib-1.2.0.jar')

}

I used java 7. How can I get rid of this error message?

Android L Preview build cannot target previous Android version. I think com.android.support:support-v4:21.0.0-rc1 is built for Android L Preview only, try to change the version to 20+ pending v21 release

EDIT :

It's possible that Google Play Services includes android-support-v4:21.0.0-rc1 . Avoid using + in gradle dependencies (i use it only for minor versions), last version of Google Play Services is 5.2.08 from Android L Preview, try to replace compile 'com.google.android.gms:play-services:+' with compile 'com.google.android.gms:play-services:5.0.89'
