主要是对google play官方demo的讲解

1.仿照demo搭建一个新的内部付费应用

1. 创建一个新的android项目，创建一个新包 包名 com.android.vending.billing

2. IInAppBillingService.aidl拷贝到新包里

新项目代码

AndroidManifest.xml

添加付费权限：<uses-permissionandroid:name="com.android.vending.BILLING"/>

activity_main.xml

onBuyGasButtonClicked：按钮调用的方法、buy_gas图片名 .png

<ImageView

android:src="@drawable/buy_gas"

android:onClick="onBuyGasButtonClicked"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_marginBottom="20dp"/>
