我很新鲜android，我正在开发pos应用系统的android应用程序。我已经测试了从制造商收到的POS(销售点)系统的android演示应用程序。我添加了它的库到我的android项目。但打印机没有为我的应用程序工作，但该应用程序正常工作。如何添加打印机sdk POS系统android应用程序

这是制造商打印机Activtity：

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);

ThermalPrinter.enlargeFontSize(2, 2);

} else if (wordFont == 2) {

ThermalPrinter.setFontSize(2);

} else if (wordFont == 1) {

ThermalPrinter.setFontSize(1);

}

ThermalPrinter.setGray(printGray);

ThermalPrinter.addString("test123");

ThermalPrinter.printString();

ThermalPrinter.clearString();

ThermalPrinter.walkPaper(100);

} catch (Exception e) {

e.printStackTrace();

return;

}

ThermalPrinter.stop(PrinterActivity.this);

Log.v(TAG, "The Print Progress End !!!");

*****这是打印按钮 -

buttonContentPrint.setOnClickListener(new View.OnClickListener() {

1.can我可以在我的项目中添加制造商应用程序作为模块？

2.how在我的应用程序添加此代码，以及其他特殊的方式来做到这一点
