Activity?  Or Dialog?

Although I was not 100% anti-activity in the design doc, I realized that android
is more likely to kill the background page if you use an activity, so I think
you should avoid that at all possible.

+    private final Context mApplicationContext;
+    private PaymentRequestClient mClient;
+
+    /**
+     * Builds a PaymentRequest.
+     *
+     * @param applicationContext The application context.
+     */
+    public PaymentRequestActivity(Context applicationContext) {
+        mApplicationContext = applicationContext;
+    }
+
+    @Override
+    public void setClient(PaymentRequestClient client) {
+        mClient = client;
+    }
+
+    @Override
+    public void show(String[] supportedMethods, PaymentDetails details, PaymentOptions options,
+            String stringifiedData) {
+        assert mClient != null;
+        mClient.onError();
+    }
+
+    @Override
+    public void abort() {}
+
+    @Override
+    public void complete(boolean success) {
+        assert mClient != null;
+        mClient.onComplete();
+    }
+
+    @Override
+    public void close() {}
+
+    @Override
+    public void onConnectionError(MojoException e) {}
+}
