试图将Google Pay集成到我的Android应用中

莫问天涯路几重，轻衫侧帽且从容。这篇文章主要讲述试图将Google Pay集成到我的Android应用中相关的知识，希望能为你提供帮助。
【试图将Google Pay集成到我的Android应用中】我正在尝试将Google Pay集成到我的android应用中。我正在追踪发现的this tutorial，但是当我运行代码时，却不断收到此错误E/AndroidRuntime: FATAL EXCEPTION: main Process: com.myapp.sqill, PID: 12555 android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=upi://pay?pa=your-merchant-vpa@xxx& pn=your-merchant-name& mc=your-merchant-code& tr=your-transaction-ref-id& tn=your-transaction-note& am=your-order-amount& cu=INR pkg=com.google.android.apps.nbu.paisa.user }
到目前为止是我的代码。在此先感谢
// PaymentPageActivity.java

Button pay_button; final int UPI_PAYMENT=0; Integer amount=5; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_payment_page); pay_button=findViewById(R.id.pay); //startActivitypay_button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { payUsingUpi(); } }); }private void payUsingUpi() {Uri uri = new Uri.Builder() .scheme("upi") .authority("pay") .appendQueryParameter("pa", "your-merchant-vpa@xxx") .appendQueryParameter("pn", "your-merchant-name") .appendQueryParameter("mc", "your-merchant-code") .appendQueryParameter("tr", "your-transaction-ref-id") .appendQueryParameter("tn", "your-transaction-note") .appendQueryParameter("am","$5.00") .appendQueryParameter("cu", "INR").build(); String GOOGLE_PAY_PACKAGE_NAME = "com.android"; int GOOGLE_PAY_REQUEST_CODE = 123; Intent intent = new Intent(Intent.ACTION_VIEW); intent.setData(uri); intent.setPackage(GOOGLE_PAY_PACKAGE_NAME); startActivityForResult(intent, GOOGLE_PAY_REQUEST_CODE); }

答案您可能使用了错误的软件包名称。根据以下example：

String GOOGLE_PAY_PACKAGE_NAME = "com.google.android.apps.nbu.paisa.user"; int GOOGLE_PAY_REQUEST_CODE = 123; Uri uri = new Uri.Builder() .scheme("upi") .authority("pay") .appendQueryParameter("pa", "your-merchant-vpa@xxx") .appendQueryParameter("pn", "your-merchant-name") .appendQueryParameter("mc", "your-merchant-code") .appendQueryParameter("tr", "your-transaction-ref-id") .appendQueryParameter("tn", "your-transaction-note") .appendQueryParameter("am", "your-order-amount") .appendQueryParameter("cu", "INR") .appendQueryParameter("url", "your-transaction-url") .build(); Intent intent = new Intent(Intent.ACTION_VIEW); intent.setData(uri); intent.setPackage(GOOGLE_PAY_PACKAGE_NAME); activity.startActivityForResult(intent, GOOGLE_PAY_REQUEST_CODE);

包裹名称应为com.google.android.apps.nbu.paisa.user。
