没想到遇到了以下问题: 停止未恢复的 Activity 。
我主要致力于将 paypal SDK 集成到应用程序中。特别是，我认为错误源于以下尝试:
我试图从存储在 Parse.com 中的信息生成价格和商品名称
private PayPalPayment getThingToBuy(String paymentIntent) {
return new PayPalPayment(new BigDecimal("mActivityPrice"), "USD", "mActivityName",
paymentIntent);
}
mActivityPrice 和 mActivityName 的来源
String mActivityPrice = ParseUser.getCurrentUser().getString("ActivityPrice");
String mActivityName = ParseUser.getCurrentUser().getString("ActivityName");

如有任何帮助，我们将不胜感激，如果需要进一步说明，请告诉我。
最佳答案
在您的 getThingToBuy 实现中，移除 mActivityPrice 和 mActivityName 周围的双引号。就是调用 BigDecimal 构造函数时带有一个不能被解释为小数的字符串正在爆炸。
这个有效:
private PayPalPayment getThingToBuy(String paymentIntent) {
String mActivityPrice = "1.25";
String mActivityName = "The Activity Name";
return new PayPalPayment(new BigDecimal(mActivityPrice), "USD", mActivityName,
paymentIntent);
}
