如何创建和启动 Intent? [英] How can I create and start an Intent?

问题描述

我想知道如何使用它来创建和启动意图:

I was wondering how I can create and start an intent using this:

"qsrtech.posprintdriver/.printservice"

"qsrtech.posprintdriver/.printservice"

我下载了 POS 打印机驱动程序 (ESC) 应用程序(这是我尝试访问的应用程序).

I downloaded the POS Printer Driver (ESC) app (which is the app I am trying to access).

我试过了:

        String PrintPage = "qsrtech.posprintdriver/.printservice";
        Intent intent = new Intent(Intent.ACTION_MAIN);             
        intent.setComponent(ComponentName.unflattenFromString(PrintPage));             
        intent.addCategory(Intent.CATEGORY_LAUNCHER );             
        startActivity(intent); 

但是，我收到一条错误消息:未找到处理此意图的活动"

However, I get an error saying: "No activity found to handle this intent"

我想知道我是否可以做些什么来访问这个意图?问题是我不确定我是从其他应用访问 Activity 还是后台服务(可能是 Intent 服务?).

I was wondering if there is anything I can do to access this intent? The thing is that I'm not sure if I'm accessing an activity or a background service (probably an intent service?) from a different app.

推荐答案

你可以试试这个:

Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra("Data", "Test printer\n\n");
sendIntent.setComponent(new ComponentName("qsrtech.posprintdriver","qsrtech.posprintdriver.printservice"));
startService(sendIntent);
