Android 如何接入穿山甲广告?

目录

下载SDK
集成SDK

  • AndroidManifest配置
  • provider配置
  • 运行环境配置
  • 白名单配置

工具类

下载SDK

首先去穿山甲官网注册账号以及创建应用

点击进入平台 (我的是创建完账号并且登录之后是这个样子)

进来之后是如下界面

然后依次点击流量—>应用会进入到以下界面

然后点击创建应用根据提示走即可

创建完毕之后去依次点击流量–>代码位创建广告位 根据自己的需求去创建即可

最后点击接入选择SDK下载与文档选择Android平台SDK

下载完成之后开始集成

集成SDK

集成方式一

    导入aar及SDK依赖的jar包

将本SDK压缩包内的open_ad_sdk.aar复制到Application Module/libs文件夹(没有的话须手动创建), 并将以下代码添加到您app的build.gradle中:

dependencies {
    implementation(name: 'open_ad_sdk_4.4.0.2', ext: 'aar')
}

方式二:从穿山甲3.5.0.6版本开始,开发者也可以使用Gradle依赖导入穿山甲SDK

  • 步骤一:添加仓库
    在project级别的build.gradle文件中添加Maven的引用,url ‘https://artifact.bytedance.com/repository/pangle’
    示例:
allprojects {
    repositories {
        maven {
          url 'https://artifact.bytedance.com/repository/pangle'
            }
      }
}

步骤二:添加依赖
在主modulebuild.gradle文件添加SDK依赖

dependencies {
     implementation 'com.pangle.cn:ads-sdk-pro:4.4.0.9'
}

Gradle版本要求:

自3400版本开始,穿山甲支持了Android R,引入了Android R的 标签,需要对gradle版本进行限制,限制范围为:3.3.3、 3.4.3、 3.5.4、3.6.4、4.0.1 ,开发者根据自身情况酌情升级

AndroidManifest配置

添加权限

<!--必要权限-->
<uses-permission android:name="android.permission.INTERNET" />

<!--必要权限,解决安全风险漏洞,发送和注册广播事件需要调用带有传递权限的接口-->
<permission      android:name="${applicationId}.openadsdk.permission.TT_PANGOLIN"
        android:protectionLevel="signature" />

    <uses-permission android:name="${applicationId}.openadsdk.permission.TT_PANGOLIN" /> 
   

<!--可选权限-->
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES"/>
<uses-permission android:name="android.permission.GET_TASKS"/>

<!--可选,穿山甲提供“获取地理位置权限”和“不给予地理位置权限,开发者传入地理位置参数”两种方式上报用户位置,两种方式均可不选,添加位置权限或参数将帮助投放定位广告-->
<!--请注意:无论通过何种方式提供给穿山甲用户地理位置,均需向用户声明地理位置权限将应用于穿山甲广告投放,穿山甲不强制获取地理位置信息-->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

<!-- 如果视频广告使用textureView播放,请务必添加,否则黑屏 -->
<uses-permission android:name="android.permission.WAKE_LOCK" />

<!--demo场景用到的权限,不是必须的-->
<uses-permission android:name="android.permission.RECEIVE_USER_PRESENT" />
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
<uses-permission android:name="android.permission.EXPAND_STATUS_BAR" />

<!-- 穿山甲3400版本新增:建议添加“query_all_package”权限,穿山甲将通过此权限在Android R系统上判定广告对应的应用是否在用户的app上安装,避免投放错误的广告,以此提高用户的广告体验。若添加此权限,需要在您的用户隐私文档中声明! -->
<uses-permission android:name="android.permission.QUERY_ALL_PACKAGES"/>

注意: 穿山甲SDK不强制获取以上权限,即使没有获取可选权限SDK也能正常运行;获取以上权限将帮助穿山甲优化投放广告精准度和用户的交互体验,提高eCPM。

建议在广告请求前,合适的时机调用SDK提供的方法,在用户可以授权的情况下获取到声明中的权限,提高广告变现效率

//TTAdManager接口中的方法,context可以是Activity或Application
void requestPermissionIfNecessary(Context context);

provider配置

注意
(1)为不影响下载类型广告使用 无论APP处于任何阶段provider都需要在清单文件中正常配置
(2)为不影响到广告的转化及收益 请务必在清单文件中配置xxx.TTMultiProvider
(3)${applicationId} 必须与开发者包名保持一致,否则会引发崩溃问题

适配Anroid7.0及以上如果您的应用需要在Anroid7.0及以上环境运行,请在AndroidManifest中添加如下代码:

<provider
    android:name="com.bytedance.sdk.openadsdk.TTFileProvider"
    android:authorities="${applicationId}.TTFileProvider"
    android:exported="false"
    android:grantUriPermissions="true">
   <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/file_paths" />
</provider>

在res/xml目录下,新建一个xml文件file_paths,在该文件中添加如下代码:

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
   <!--为了适配所有路径可以设置 path = "." -->
   <external-path name="tt_external_root" path="." />
   <external-path name="tt_external_download" path="Download" />
   <external-files-path name="tt_external_files_download" path="Download" />
   <files-path name="tt_internal_file_download" path="Download" />
   <cache-path name="tt_internal_cache_download" path="Download" />
</paths>

为了适配下载和安装相关功能,在工程中引用的包 com.android.support:support-v4:24.2.0使用24.2.0以及以上版本

注意:单进程或多进程都必须配置

<provider
android:name="com.bytedance.sdk.openadsdk.multipro.TTMultiProvider"   android:authorities="${applicationId}.TTMultiProvider"   android:exported="false" />

运行环境配置

本SDK可运行于Android4.0 (API Level 14) 及以上版本。

如果开发者声明targetSdkVersion到API 23以上,请确保调用本SDK的任何接口前,已经申请到了SDK要求的所有权限,否则SDK部分特性可能受限

代码混淆

如果您需要使用proguard混淆代码,需确保不要混淆SDK的代码。 请在proguard.cfg文件(或其他混淆文件)尾部添加如下配置:35xx以及以下版本混淆规则如下:

-keep class com.bytedance.sdk.openadsdk.** { *; }
-keep public interface com.bytedance.sdk.openadsdk.downloadnew.** {*;}
-keep class com.pgl.sys.ces.* {*;}
-keep class com.bytedance.embed_dr.** {*;}
-keep class com.bytedance.embedapplog.** {*;}

36xx版本-38xx版本混淆规则如下:

-keep class com.bytedance.sdk.openadsdk.** { *; }
-keep public interface com.bytedance.sdk.openadsdk.downloadnew.** {*;}
-keep class ms.bd.c.**{*;}
-keep class com.bytedance.mobsec.**{*;} 
-keep class com.bytedance.embed_dr.** {*;}
-keep class com.bytedance.embedapplog.** {*;}
-keep interface com.bytedance.frameworks.baselib.network.http.cronet.I* {*;}
-keepnames class com.bytedance.framwork.core.sdkmonitor.SDKMonitorUtils

3900版本及以上版本混淆规则如下:

-keep class com.bytedance.sdk.openadsdk.** { *; }
-keep class com.bytedance.frameworks.** { *; }
 
-keep class ms.bd.c.Pgl.**{*;}
-keep class com.bytedance.mobsec.metasec.ml.**{*;}
 
-keep class com.ss.android.**{*;}
 
-keep class com.bytedance.embedapplog.** {*;}
-keep class com.bytedance.embed_dr.** {*;}
 
-keep class com.bykv.vk.** {*;}

4000版本混淆规则:以aar包里的混淆文件为准

注意: SDK代码被混淆后会导致广告无法展现或者其它异常

支持架构

注意: 3900以及以上版本SDK默认支持armeabi-v7a,arm64-v8a两种架构,如果有其他架构需求,请联系技术支持同学; 3900以下版本SDK中使用的so文件支持五种架构:x86,x86_64,armeabi,armeabi-v7a,arm64-v8a如果您应用中支持的架构超出这 五种,请在build.gradle中使用abiFilters选择支持的架构。如下所示:

ndk { // 设置支持的 SO 库构架,注意这里要根据你的实际情况来设置 
   abiFilters  armeabi-v7a ,  arm64-v8a , x86 , x86_64 ,  armeabi 
}

说明:
1、36xx-38xx版本中穿山甲增加了libmetasec_ml.so 库。
2、36xx-38xx版本若开发者使用armeabi架构,那么需要把armeabi-v7a下的 libmetasec_ml.so 拷贝到armeabi目录下使用。

白名单配置

注意:平台SDK包中whiteList.txt 白名单上的资源不支持混淆

配置完成之后创建一个SDK初始化脚本内容如下 初始化调用是在开屏界面调用 调用初始化成功之后会自动调用开屏代码
