ADB Shell获取Toast消息

Question

I have been working around a Java test framework and ended up with testing an android application which does a lot of toast messages.

The problem is the framework doesn't use anything other than ADB and I can't use any extra libs.

so Is there any way to get the toasted message from an application via adb? I wouldn't mind writing hundreds of lines for this alone..

Answer 1

You can check toast messages through events with adb shell uiautomator events from the command line. Within your java test framework, however, you can create a method for code reuse that runs this command and parses it for whatever string you want to compare it to with a try block as such:

try {
        Process process = Runtime.getRuntime().exec("uiautomator events");
        BufferedReader bufferedReader = new BufferedReader(
                new InputStreamReader(process.getInputStream()));

        StringBuilder log=new StringBuilder();
        String toastMessage;
        while ((toastMessage = bufferedReader.readLine()) != null) {
            log.append(toastMessage).append("\n");

        if (toastMessage.contains(myToastStringVar)) {
              Log.i("ToastMessageMatcher", "" // <-- your info message);
            } else {
              Log.e("ToastMessageMatcher", "" // <-- your error message);
            }
        }
        bufferedReader.close();
        process.waitFor();
        System.out.println(log.toString());
    } catch (IOException | InterruptedException e) {
        e.printStackTrace();
    }

This can likewise be directly in your derivatives too.
