Android设置。ACTION_LOCATION_SOURCE_SETTINGS导致崩溃

Question

I am using the following line of code to redirect user to location settings screen

startActivityForResult(new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS), 0); 

It works fine on most devices, but crashes on some Samsung devices with an exception :

android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.settings.LOCATION_SOURCE_SETTINGS }

Is there a better way to handle location settings ?

Is there a better way to handle location settings ?

Pretty much all those action strings on the Settings class mention in the JavaDocs that the activity may not exist and so you should handle that appropriately (eg, wrap your startActivity() call in a ActivityNotFoundException handler).

In this case, there isn't an obvious fallback option other than ACTION_SETTINGS . You might display a Snackbar or dialog from the exception handler indicating that this device does not have direct third-party access to the location settings screen.

Also note that startActivityForResult() is useless in your situation; just use startActivity() .
