您好，我正在尝试遵循本教程

Link

完成所有操作后， list 中出现错误

Error:(8, 5) uses-sdk:minSdkVersion 8 cannot be smaller than version 9                declared in library     C:\Users\Zezo2\AndroidStudioProjects\AndroidPushNotificationsUsingGCM1\app\build    \intermediates\exploded-aar\com.google.android.gms\play-    services\6.5.87\AndroidManifest.xml


Error:(8, 5) Execution failed for task ':app:processDebugManifest'.
> Manifest merger failed : uses-sdk:minSdkVersion 8 cannot be smaller than      version 9 declared in library C:\Users\Zezo2\AndroidStudioProjects\AndroidPushNotificationsUsingGCM1\app\build\intermediates\exploded-aar\com.google.android.gms\play-services\6.5.87\AndroidManifest.xml
Suggestion: use tools:overrideLibrary="com.google.android.gms" to force usage

这是我的 build.geadle

    apply plugin: 'com.android.application'

android {
compileSdkVersion 'Google Inc.:Google APIs:8'
buildToolsVersion "21.1.1"

defaultConfig {
    applicationId "com.androidhive.pushnotifications"
    minSdkVersion 8
    targetSdkVersion 16
}

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
    }
}

}

dependencies {
compile 'com.android.support:support-v4:18.0.0'
compile 'com.google.android.gms:play-services:+'

}

基本上，您使用的库也有您需要遵守的最低 SDK 版本..

uses-sdk:minSdkVersion 8 cannot be smaller than version 9

您需要编辑您的 Android 项目来更新您的 minSdkVersion

• 更新 src/build.gradle - 确保是 src 文件夹下的
• 同步渐变按钮
• 重建项目
• 更新 build.gradle minSdkVersion 后，您必须单击 同步 gradle 文件的按钮(“将项目与 Gradle 文件同步”)。
