AS生成的build.gradle文件，为什么在4.0的手机上不能运行

android {
compileSdkVersion 25
buildToolsVersion "23.0.2"

defaultConfig {
    applicationId "com.etag.etbalance"
    minSdkVersion 14
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:25.3.1'
}
