如何添加打印机sdk POS系统android app

Question

我对 android 比较新鲜，我正在为 pos 系统开发 android 应用程序。我已经测试了从制造商那里收到的 POS（销售点）系统的 android 演示应用程序。我将它的库添加到我的 android 项目中。但是打印机不工作我的应用程序，但该应用程序运行正常。

这是制造商打印机 Activity ：

        private class contentPrintThread extends Thread {
                @Override
                public void run() {
                    super.run();
                    setName("Content Print Thread");
                    try {
                        ThermalPrinter.start(PrinterActivity.this);
                        ThermalPrinter.reset();
                        ThermalPrinter.setAlgin(ThermalPrinter.ALGIN_LEFT);
                        ThermalPrinter.setLeftIndent(leftDistance);
                        ThermalPrinter.setLineSpace(lineDistance);
                        if (wordFont == 4) {
                            ThermalPrinter.setFontSize(2);
                            ThermalPrinter.enlargeFontSize(2, 2);
                        } else if (wordFont == 3) {
                            ThermalPrinter.setFontSize(1);

1.我可以在我的项目中添加制造商应用程序作为模块吗？

2.如何在我的应用程序中添加此代码，以及任何其他特殊方法

Answer 1

在提供的 SDK 制造商上，有一个库文件夹，您将该 Lib 文件夹复制到您的项目中，然后在复制后您右键单击 lib 文件夹，我假设您已将其复制到 app 文件夹下，右键单击 libs 文件夹，然后添加为库，它将被添加，现在您可以将打印机 Activity 包括到您的 MainActivity 中，在您输入数据的地方创建表单，然后将该数据写入您的 btnprint

Answer 2

添加演示应用程序中的所有库以及 jniLibs，如下所示jniLibs
