Android fundamentals 02.3: Implicit intents

[thpir]

When testing app on Samsung A50, Logging returns "Can't handle this intent!" when testing the intent to open a link and location. My code is exactly the same as the solution code. The problem was solved by removing the If-Else statement and put the "startActivity(intent)" right under the parsing of the URI.

Solution:

public void openWebsite(View view) { // Get the URL text. String url = mWebsiteEditText.getText().toString();

    // Parse the URI and create the intent.
    Uri webpage = Uri.parse(url);
    Intent intent = new Intent(Intent.ACTION_VIEW, webpage);
    // Find an activity to hand the intent and start that activity
    startActivity(intent);

    /*
    // Find an activity to hand the intent and start that activity
    if (intent.resolveActivity(getPackageManager()) != null) {
        startActivity(intent)
    } else {
        Log.d("ImplicitIntents", "Can't handle this intent!");
    }*/
}

public void openLocation(View view) {
    // Get the string indicating a location. Input is not validated; it is passed to the location handler intact.
    String loc = mLocationEditText.getText().toString();

    // Parse the location and create the intent.
    Uri addressUri = Uri.parse("geo:0,0?q=" + loc);
    Intent intent = new Intent(Intent.ACTION_VIEW, addressUri);
    // Find an activity to handle the intent, and start that activity.
    startActivity(intent);

    /*
    // Find an activity to handle the intent, and start that activity.
    if (intent.resolveActivity(getPackageManager()) != null) {
        startActivity(intent);
    } else {
        Log.d("ImplicitIntents", "Can't handle this intent!");
    }*/
}

In which lesson and step of the codelab can this issue be found? Lesson number + step number.

[4. Task 2: Implement the Open Website button] - step 4 [5. Task 3: Implement the Open Location button] - step 4

How to reproduce? What are the exact steps to reproduce the problem? Copy the solution code - run app on Samsung Galaxy A50 (I don't think the device type matters)
