Error while integrating paypal in Android?

Question

I am trying to integrate paypal in my Android App. I am following this method http://sunil-android.blogspot.in/2013/10/paypal-android-sdk-with-multiple-in-app.html

I have added the Paypal Android SDK library in my App.

But it throws me a error that many methods like this PaymentActivity.ENVIRONMENT_LIVE; cannot be resolved.

Thanks for your help

If you are using android studio. Then just add the paypal sdk to your app level build.gradle file.

compile 'com.paypal.sdk:paypal-android-sdk:2.14.2'

Now you can use the following code to accept payment. Remember you also need your paypal client id. You can get it by creating an app to developer.paypal.com

private void getPayment() {
    //Getting the amount from editText
    paymentAmount = editTextAmount.getText().toString();

    //Creating a paypalpayment 
    PayPalPayment payment = new PayPalPayment(new BigDecimal(String.valueOf(paymentAmount)), "USD", "Simplified Coding Fee",
            PayPalPayment.PAYMENT_INTENT_SALE);

    //Creating Paypal Payment activity intent 
    Intent intent = new Intent(this, PaymentActivity.class);

    //putting the paypal configuration to the intent 
    intent.putExtra(PayPalService.EXTRA_PAYPAL_CONFIGURATION, config);

    //Puting paypal payment to the intent 
    intent.putExtra(PaymentActivity.EXTRA_PAYMENT, payment);

    //Starting the intent activity for result
    //the request code will be used on the method onActivityResult 
    startActivityForResult(intent, PAYPAL_REQUEST_CODE);
}

The activityresult code would be

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    //If the result is from paypal 
    if (requestCode == PAYPAL_REQUEST_CODE) {

        //If the result is OK i.e. user has not canceled the payment 
        if (resultCode == Activity.RESULT_OK) {
            //Getting the payment confirmation 
            PaymentConfirmation confirm = data.getParcelableExtra(PaymentActivity.EXTRA_RESULT_CONFIRMATION);

            //if confirmation is not null 
            if (confirm != null) {
                try {
                    //Getting the payment details 
                    String paymentDetails = confirm.toJSONObject().toString(4);
                    Log.i("paymentExample", paymentDetails);

                    //Starting a new activity for the payment details and also putting the payment details with intent 
                    startActivity(new Intent(this, ConfirmationActivity.class)
                            .putExtra("PaymentDetails", paymentDetails)
                            .putExtra("PaymentAmount", paymentAmount));

                } catch (JSONException e) {
                    Log.e("paymentExample", "an extremely unlikely failure occurred: ", e);
                }
            }
        } else if (resultCode == Activity.RESULT_CANCELED) {
            Log.i("paymentExample", "The user canceled.");
        } else if (resultCode == PaymentActivity.RESULT_EXTRAS_INVALID) {
            Log.i("paymentExample", "An invalid Payment or PayPalConfiguration was submitted. Please see the docs.");
        }
    }
}

That blog post refers to version 1.x of the SDK, but you're most likely using 2.x. I recommend you use our latest GitHub docs for the latest integration information.
