Android应用程式，Google Maps Java的api位置验证

Question

I'm using Android Studio to create an app that utilizes google maps api. I am having trouble validating if the user input is an actual location.

ie if the user enters "fdfdfaef", program crashes.

i have the following code to store the user "location" input:

address = geocoder.getFromLocationName(location, 1)

Any help on how to check if the input is valid or not or at least to prevent a crash. Thanks and appreciate it.

Since you haven't posted any code, I will go out on a limb and suggest that you might be doing this on your main UI thread.

From the doc ,

The query will block and returned values will be obtained by means of a network lookup. The results are a best guess and are not guaranteed to be meaningful or correct. It may be useful to call this method from a thread separate from your primary UI thread.

Try doing a async task that requests information using the Geocoding API. On getting a result, update the UI. Offloading to an AsyncTask will prevent the crash, at the very least.

Does that help you?
