引言:
有Landi,Newland,银联等智能pos机开发,本文档以MagCard为例,其他相关操作调用类似,本文档仅供学习
详情:
Landi相关文档和newland相关文档,都以MagCard为例
流程:
Landi pos机MagCard调用流程:
1:导入landi提供的eptapilibrary.jar包
compile files('src/main/jniLibs/armeabi/eptapilibrary.jar')2:初始化MagCardReader,通过调用getInstance方法
MagCardReader.getInstance().searchCard(listener);3:在activity中使用范例
MagCardReader.OnSearchListener listener = new MagCardReader.OnSearchListener() {
@Override
public void onCrash() {
}
@Override
public void onFail(int code) {
String errorMessage = getErrorDescription(code);
showErrorMessage("ERROR ["+errorMessage+"]");
}
@Override
public void onCardStriped(boolean[] hasTrack, String[] track) {
StringBuilder infoBuilder = new StringBuilder();
for(int i=0; i<3; i++) {
infoBuilder.append("TRACK ");
infoBuilder.append(i+1);
infoBuilder.append(" - exist ? ");
infoBuilder.append(hasTrack[i]);
if(hasTrack[i]) {
infoBuilder.append(" [");
infoBuilder.append(track[i]);
infoBuilder.append("]");
}
infoBuilder.append("\n");
}
infoBuilder.append("\n\n");
infoBuilder.deleteCharAt(infoBuilder.length()-1);
displayMagCardInfo(infoBuilder.toString());
}
@Override
public boolean checkValid(int[] trackStates, String[] track) {
if(trackStates[1] != TRACK_STATE_NULL && trackStates[1] != TRACK_STATE_OK) {
return false;
}
if(track[1].length() < 21 || track[1].length() > 37) {
return false;
}
if(track[1].indexOf('=') < 12) {
return false;
}
if(trackStates[1] == TRACK_STATE_NULL && trackStates[2] == TRACK_STATE_NULL) {
return false;
}
return true;
};
public String getErrorDescription(int code) {
switch(code) {
case ERROR_NODATA:
return "no data";
case ERROR_NEEDSTART:
return "need restart search";//This error never happened
case ERROR_INVALID:
return "has invalid track";//
}
return "unknown error - "+code;
}
};
public void searchCard() {
try {
MagCardReader.getInstance().searchCard(listener);
} catch (RequestException e) {
e.printStackTrace();
}
}Newland POS机MagCard调用流程:
1:导入厂商提供的sdkserviceapi.jar包
2:manifest.xml配置service
<service android:name=".service.MyService">
<intent-filter>
<action android:name="com.zacloud.device_service" />
</intent-filter>
</service>3:理解设备接口服务IDeviceService,这是接口具体信息,只是看看而已
