我不敢相信没有人知道如何解决这个问题。我想在我的应用程序中添加一个横幅，但安卓工作室的Gradle系统试图让我明白这不是一个好主意。它看起来像这样：
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "22.0.1"
defaultConfig {
applicationId "com.(package).(name)"
minSdkVersion 15
targetSdkVersion 21
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'com.google.android.gms:play-services:7.0.0'
}
日志：

通过SDK Manager，您需要确保Android Support Repository是最新的，这就是解决Android支持库依赖关系的地方。
addcompile 'com.android.support:support-v4:22.0.0'
