kandi X-RAY | AndroidDataStorage Summary
An easy-to-use and high-performance library for storing data in the Android system. ###1. Obtain the implementation of data storage. Obtain the implementation of data storage through DataStorageFactory. Now it only supports the database version of data storage and more versions will be supported in the future. The framework stores an object according to its class's id and its own id. The former one is called the "class id" and the latter one is called the "object id". If the framework stores two objects which have the same class id and the same object id, the one stored earlier is replaced by the one stored later. The following will tell you how to give an object a class id and an object id. Add a @ClassId annotation on the class you want to store. Give the annotation a value, which indicates the class id. Distinct classes should have distinct class ids. If you guarantee that the class name remains the same in different versions of apps even after ProGuard is used, then the @ClassId annotation is not necessary. In this case, if you do not add a @ClassId annotation, the class name will be the class id. Often the object contains an object id as a field in itself. If there is such a field, then add an @ObjectId annotation on the field. Note that this field must be of the String type. If there is no such a field, then you should provide an object id when storing and loading the object.

(Solution has been found, please avoid reading on.)
I am creating a pixel art editor for Android, and as for all pixel art editors, a paint bucket (fill tool) is a must need.
To do this, I did some research on flood fill algorithms online.
I stumbled across the following video which explained how to implement an iterative flood fill algorithm in your code. The code used in the video was JavaScript, but I was easily able to convert the code from the video to Kotlin:

...ANSWER
Answered 2021-Dec-29 at 08:28I think the performance issue is because of expandToNeighbors
method generates 4 points all the time. It becomes crucial on the border, where you'd better generate 3 (or even 2 on corner) points, so extra point is current position again. So first border point doubles following points count, second one doubles it again (now it's x4) and so on.
If I'm right, you saw not the slow method work, but it was called too often.
QUESTION
I switched from the deprecated GDPR Consent Library to the new User Messaging Platform, and used the code as stated in the documentation.
I noticed that when the user clicks on Manage Options then Confirm choices, ads will stop displaying altogether (Ad failed to load, no ad config), and I can't find anyway to check if the user didn't consent to the use of personal data.
This is problematic as my app relies purely on ads, and I will be losing money if ads don't show up, so I want to make it mandatory for users to consent to the use of their personal data, otherwise the app should be unusable.
I have made a test project on Github so everyone can test this behavior. If you are not using an emulator, then you need to change the "TEST_DEVICE_ID" to yours.
How can I achieve this?
...ANSWER
Answered 2021-Nov-02 at 17:50I found a workaround for this, but this is no final official solution.
It seems that if a user consented to Personalized ads, a string in SharedPreferences
, which key is IABTCF_VendorConsents, will contain ones and zeros corresponding to some vendors (I think). If he didn't consent, this string will be equal to 0.
QUESTION
We have a react-native application running in production with firebase phone auth. Lately, we received feedback from users owning new Huawei devices not being able to authenticate with their phone numbers using firebase.
Since a lot of users started having this issue, we decided to implement Huawei auth services only for devices under HarmonyOS and keep the regular firebase phone authentication for other users.
After integrating the Huawei App Gallery Connect Auth SDK in our react-native app, we are able to receive the OTP and sign the user in using credentialWithVerifyCode
and we are also able to retrieve the user's token using

On Android 12,
If we open an activity
Go to the home screen of the phone to change the wallpaper
Switch back to our activity, the activity restarts.
It seems it is related to the Material You theming.
I would like to disable the restarting of activity when my app comes to the foreground. Is there a way?
...ANSWER
Answered 2021-Oct-31 at 18:39It is a non-traditional configuration change. By "non-traditional", I mean that it cannot be blocked by android:configChanges
— your activity will be destroyed and recreated whether you like it or not.
If you have Configuration
objects from before and after the change, you can determine that this scenario occurred by calling diff()
on the newer
Configuration
to compare it to the older one:

Answered 2021-Nov-05 at 03:21Apparently, it's an Android Studio filtering issue.
I'm having the Tracking

When I remove a character from the log, then the filter get corrected. After putting back the character, the filter is still okay.

QUESTION
I'm starting to get errors when I am executing a test for a release variant which was always working fine. The code has always been executed in a Docker container so we can ensure that the build will always be clean.
Today for some reason with no changes at all to the code, I am starting to see errors on the test run:
...ANSWER
Answered 2021-Sep-03 at 11:31I've found the issue and I was able to fix it.
The issue was that one of the external libraries the app depends on has a dependency on androidx.core:core-ktx:+
which meant that was always compiling with the latest version. My app is still working on SDK 28, but the latest version of androidx.core:core-ktx
has the minimal SDK of 31, which resulted in this conflict.
