Imported a library to an old project and got error in Android Studio

I imported a ui-library to an old project in android studio. Everything goes fine until I add compile project(':Android Library' to build.gradle of my app module. Here is the setting in build.gradle of app and library respectively.
App
android {
compileSdkVersion 25
buildToolsVersion "25.0.3"
defaultConfig {
applicationId "com.chimaera.AppName"
minSdkVersion 18
targetSdkVersion 25
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
compile 'com.android.support:support-core-ui:25.3.1'
compile 'com.android.support:design:25.3.1'
compile project(':MaterialDesign')
testCompile 'junit:junit:4.12'
Library module
android {
compileSdkVersion 22
buildToolsVersion '25.0.0'
defaultConfig {
minSdkVersion 16
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
dependencies {
compile 'com.nineoldandroids:library:2.4.+'
compile 'com.android.support:support-v4:22.+'
compile fileTree(dir: 'libs', include: '*.jar')
(I forgot to paste the error.) Here is the error tips.

It jumped to a value.xml seems unrelated to this error.
I set minifyEnabled to false for release but keep debug setting blank. Do I need to set debug as well. Is there anything wrong with version settings to cause imported error?

After import to android studio, gradle task “app:dexDebug” fails

I have the following gradle file in my android app:
apply plugin: 'com.android.application'
android {
compileSdkVersion 20
buildToolsVersion "20.0.0"
defaultConfig {
applicationId "com.example.test.forum"
minSdkVersion 16
targetSdkVersion 19
versionCode 1
versionName "1.0"
}
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
//configurations {
// all*.exclude group: 'com.android.support', module: 'support-v4'
//}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:19+'
compile 'org.java-websocket:Java-WebSocket:1.3.0'
}
and the bug output is Error code: 2; Output: UNEXPECTED TOP-LEVEL EXCEPTION.
When I uncomment the configurations part of the file I get Can't find package v4 (support) although I have it installed from the sdk. Any ideas on how I can solve this?
