1)下载
http://developer.android.com/guide/google/play/billing/billing_integrate.html#billing-download
2)添加
http://developer.android.com/guide/google/play/billing/billing_integrate.html#billing-add-aidl
3) 在你的 android 清单文件中添加权限
http://developer.android.com/guide/google/play/billing/billing_integrate.html#billing-permission
现在您的项目应该如下所示...
4) 放置公钥（您可以在开发者控制台的
编辑配置文件的底部）在 Security.java 行中说
String base64EncodedPublicKey = "你的公钥在这里"
5) 最后你的带有按钮的活动应该是这样的
公共类 YourActivity 扩展 Activity 实现 OnClickListener {
String issueProductId = "您的产品 ID";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.updates);
SetInAppBilling();
Button donate = (Button) findViewById(R.id.donate);
donate.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
if (mBillingService.requestPurchase(issueProductId, null)) {
} else {
showDialog(DIALOG_BILLING_NOT_SUPPORTED_ID);
Log.i("tag", "Can't purchase on this device");
}
}
});
