These GSIs are built from the Android 10 source tree but contain the following backward-compatible configurations for devices upgraded from Android 8 or 8. To test devices launching on Android 8 or 8. In earlier versions of Android, devices implementing Keymaster 3 or lower were required to verify that the version info ro. Such information was typically obtained from the boot image header.
In Android 9 and higher, this requirement has changed to enable vendors to boot a GSI. Specifically, Keymaster shouldn't perform verification because the version info reported by the GSI may not match the version info reported by vendor's bootloader. For devices implementing Keymaster 3 or lower, vendors must modify the Keymaster implementation to skip verification or upgrade to Keymaster 4.
For details on Keymaster, refer to Hardware-backed Keystore. Devices upgrading to Android 10 have different upgrade paths depending on the version of vendor binaries in use on the device and the VNDK-related configurations used to build the device. The following table summarizes the legacy GSI support for upgraded devices. The most common supported use case is 2, where the legacy GSIs support devices running Android 8.

If we are both logged onto strong WiFi connections and both have iPhones will the imessage app first use the wifi before tapping into our data plans?
Hi Matt, great question thanks for asking! If both phones are connected to WiFi the phone would use that connection rather than switching to using data. It would be if the phones had no WiFi connection at all that they would use that data plan to download and watch the video.
This includes things like web browsing, checking your email, using social media such as Facebook or Twitter , streaming videos from services like YouTube, or even using the navigation feature on your phones Map app. Hi Babara, thanks for your post. If your phone is set up to remember your WiFi network and signed in, then it should switch between them automatically with no issue.
Hi Larry, our customer service team would be happy to help you with your data usage if you give us a call at or start a live chat here. Hi Hillary, all you should need to do is enable Mobile Data in the settings of your phone. As I am new to Consumer Cellular this article helps.
I have a lot to learn. Hi Meghan, thanks for your post! Not having that feature is definitely frustrating. To allow for this to go through, please power the phone completely off and back on again. If you continue to have trouble with this, give us a call at or chat with us here for further assistance. Was under the impression from others, from my own internet research, and from some of the CC employee replies above that when connected to a strong wifi signal, that any data usage would flow through wifi only.
I finally got through to a very helpful employee and his supervisor at CC that solved the mystery of why my data usage was creeping up drum roll …when sending a text message with a photo an MMS vs. No cellular data used if sending to another iPhone user. Not sure if it works the other way around from Android to iPhone, but the good news is that the CC employee and his supervisor I spoke with finally solved the mystery. I did not find this info anywhere on the internet, so well done to this employee and supervisor at CC!!
I was under the assumption that texting does not use or need data and such was the case until recently. However, lately, whenever I send a text message away from home I get the message that I have to connect to Wifi data to send the message. I was told by a CC rep that I would have to turn on data to receive a text. Is this indeed the case? Hi Rick, thanks for your question. Email Address won't be published.

I am still trying to learn about my data usage. Ashley at Consumer Cellular says. Every entity is persisted in its own table and every field in class represents the column name. DAO : Data Access Object is either be an interface or an abstract class annotated with Doa annotation, containing all the methods to define the operations to be performed on data.
The methods can be annotated with. Before creating a database, Let's create an Entity, named as Note and later, Objects of this class will be added to database. DAOs define all methods to access database, annotated with Dao annotation. The last piece of the database puzzle is the database itself. The below snippet will demonstrate the working of insert, update, and delete functionality using the Room database. For the functionallity you want to add would be good for you to use Repository Pattern.
To keep it simple, the Repository Pattern is like a class between the app and the server where you ask some data for example user name and the app doesn't know where that data is coming from database or server. The repository the will do something like this:.
This allows the app to decouple, and if you for example want to change server in a future, you would only have to change repository classes and the rest of the app will be the same. I recommend you to investigate it.
