Using SharedPreferences in Android Things

Asked 2019-Jun-23 at 23:01

I am attempting to use SharedPreferences in my Things application, but it always returns 0 for some reason. My setter is getting is logging tht it pushed the right data using the editor, but every read, even after restarting the activity, is always 0. I can't find a reason why Things wouldn't allow use of SharedPreferences, even with a needed permission change, so I'm kind of at a loss. It's obviously my code, but I can't figure out why.

My goal is to use a TextView which is touchable to simply update the date when touched. No buttons, no real interaction, and it's simple and clean. But if SharedPreferences doesn't work, this gets more difficult.

I have been all over different ways of instantiating the SharedPreferences object, in OnCreate, each time I use it to no effect. I have also used a global and local editor to the Activity, to no effect. Writes seem to succeed, but reads always return 0 for getLong(). I switch from apply() to commit() thinking maybe it's just a timing problem. However, exiting and starting the activity again doesn't show a value either, it's still 0.

What is included is the latest based on what I found in the Android documentation based on what I know about Java. The first is just what I believe to be relevant to the question. The second code sample is the full activity.

...

ANSWER

Answered 2019-Jun-23 at 15:28

The method getLong returns a long, the second parameter to the method you're calling is not a reference to be filled, but the default value to be returned in case the preference is not found.

Your code is simply not checking the return value from shared preferences.

That means either the user doesn't have a speech recognizer installed at all, or doesn't have one configured to run. There's nothing you can do to fix that, the user has to install one.

I am trying to show the current location in a TextView when a button is pressed. I can log the NMEA messages but get frequent Invalid GSV Messages. It also crashes quite quickly with an ArrayIndexOutOfBoundsException.

Can somebody help please?

The NmeaParser in the GPS driver was incorrectly handling GSV messages that were variable length. We just released a new v1.1 of the driver that fixes the parsing. You should update your app to point to the latest artifact:

The Android Things drivers open the Peripheral ports for you, so you should not be accessing the UART directly from PeripheralManager AND using the driver. Remove the following block of code:

QUESTION

What's the .driver-metadata file used for in Android Things?

Asked 2017-Jan-11 at 08:33

I've noticed in the Android Things contrib-drivers repo there's a few of these .driver-metadata files (one in each different driver folder). Does anyone know what they're for?

Example: https://github.com/androidthings/contrib-drivers/blob/master/rainbowhat/.driver-metadata

Thanks!

...

ANSWER

Answered 2017-Jan-11 at 08:33

It could that Google use a tool to autogenerate the table of available drivers in their README of the repository.

You can see from this commit: https://github.com/androidthings/contrib-drivers/commit/194d09e8f4f0e0d5f8e0eef78ea26bdc8fa4fb5a

That each of the drivers created the type from the .driver-metadata file:

TYPE="RGB LED strip"

matches the column type in the README table:

| RGB LED strip |

Further if a .driver-metadata has another key,value of sample this is also in the table (and if it doesn't then there is no sample link).

This would mean (Google's side) if a driver was added/updated you would get automatic updates elsewhere.

This is just theoretical, you need a Googler to confirm :-)
