realm-java Key Features

Mobile-first: Realm is the first database built from the ground up to run directly inside phones, tablets, and wearables.

Simple: Data is directly exposed as objects and queryable by code, removing the need for ORM's riddled with performance & maintenance issues. Plus, we've worked hard to keep our API down to very few classes: most of our users pick it up intuitively, getting simple apps up & running in minutes.

Modern: Realm supports easy thread-safety, relationships & encryption.

Fast: Realm is faster than even raw SQLite on common operations while maintaining an extremely rich feature set.

kotlin android get deleted value from realm-java

Asked 2021-Jan-19 at 02:52

I use realm-java on Android. now I'm creating profile function, but I'm not sure how to user realm correctly.

when renew profile, delete value -> store value but, I fetch value from realm, sometimes old value is taken.

To reproduce, My test repository is below, and I attached movie that problem is reproduced. https://github.com/shinsan/realm_test/

When thread id is changed, sometimes old value appears. so, if you try to reproduce, please use lower memory device such as nexus5 simulator #I think Realm instance is singleton and transaction is thread-safe, so value is always only one.

my code kotlin + Android Studio Realm Java 10.3

//Store

val realm = Realm.getDefaultInstance()
realm.executeTransaction {
val entity = AccountProfileEntity(accountProfile)
it.copyToRealmOrUpdate(entity)
}

//Delete

val realm = Realm.getDefaultInstance()
val entity = realm.where(AccountProfileEntity::class.java).findFirst()
realm.executeTransaction {
entity?.deleteFromRealm()
}

//Fetch

val realm = Realm.getDefaultInstance()
val instance = realm.where(AccountProfileEntity::class.java).findFirst()
return instance?.toModel()

// profile get function

override suspend fun getProfile(isForce: Boolean): AccountProfile =
withContext(Dispatchers.IO) {
if (isForce) {
database.delete()
}

val profile = database.fetch()
if (profile != null) {
return@withContext profile
}

val token = prefs.getToken() ?: throw NoTokenException
val response = service.getProfile(token)
database.store(response)
response
}

Please Help

I solved this. simply I forgot to close realm instance each fetch, store, delete.

QUESTION

Unable to Build an executable JAR on Spring Boot

Asked 2020-Apr-13 at 12:28

I’m currently reading a tutorial page of Spring Boot (https://spring.io/guides/gs/uploading-files/#initial) in order to check how to upload an image file, but I don’t quite understand the “Build an executable JAR” part of “Run the Application” Chapter.

I downloaded the project via the link on the tutorial’s page, and copied and pasted all the files, and I wrote “./gradlew bootRun” on the command prompt, just as written in the Build an executable JAR part of the page, but I’m unable to run the program.

To describe my situation in a more concrete way, I moved to the directory where there is a gradle file (in my PC environment, it’s C:\Users\marra\Documents\workspace-spring-tool-suite-4-4.5.1.RELEASE\ImgUpload\gs-uploading-files\initial ) by cd command, and then wrote “./gradlew bootRun” and hit the Enter button of the keyboard, but still just get an error message “BUILD FAILED”.

Here I come up with 2 questions.

・First of all, am I properly following the tutorial’s instructions in the first place? In other words, what I did is “move to the C:\Users\marra\Documents\workspace-spring-tool-suite-4-4.5.1.RELEASE\ImgUpload\gs-uploading-files\initial directory and wrote “./gradlew bootRun” and hit the Enter”, but was this the right way of running the tutorial’s program? If my way of doing it is wrong, how should I have run the program? What does “you can run the application by using ./gradlew bootRun” mean?

・Another possibility of this failure is that I get an error message even though I do follow the tutorial’s instructions properly. But in that case, which part did I do wrong? When I try to run the program and it fails, the command prompt shows an error message “Execution failed for task ':compileJava'. > Compilation failed; see the compiler error output for details.”. I did some research by myself, and for example on a page like https://github.com/realm/realm-java/issues/5910 suggests that “Any compilation failure gets this message.”. Perhaps I might not have copied and pasted all the sample code of the files properly, but the problem is that I don’t know which folder’s which file’s which line to check. I added “--debug” to the “./gradlew bootRun” command to see what kind of errors I get, and I got the following.

13:28:20.806 [LIFECYCLE] [class org.gradle.internal.buildevents.TaskExecutionLogger] > Task :compileJava FAILED        

13:28:21.249 [ERROR] [org.gradle.internal.buildevents.BuildExceptionReporter] FAILURE: Build failed with an exception.

13:28:21.250 [ERROR] [org.gradle.internal.buildevents.BuildResultLogger] BUILD FAILED in 6s

At least I hope that I can figure out “where to look at” to find the cause of the bug, or have a proper assumption like “If everything goes smoothly, the part XXX should be displayed as YYY. But in reality it’s displayed as ZZZ, so it’s possible that there is something wrong with the part AAA”, by narrowing down the scope of the problem.

I've just follow up that tutorial and the ./gradlew bootRun build and run the app successfully. In situation like this you should check what version of java you've installed on your machine(and also which version of java, gradle is using it). As you can see in the gradle build file there is: sourceCompatibility = '1.8' . If you have a java version under 1.8 your compilation will fail probably. I had also some issues in the past with Gradle building the fat boot jar, maybe that will help also: Spring boot and Gradle multi-modules project, failed to load dependencies correctly

QUESTION

What happened to Google's sideload check documentation?

Asked 2020-Mar-10 at 20:28

When using app bundles, there is a risk that a user will "sideload" a customised APK onto an incompatible device. This may cause a crash, as the required densities / languages won't be present.

To resolve this, there is a handy MissingSplitsManager inside Google Play Core. This shows the user a helpful error on startup instead of crashing. All that needs to be done is adding the following to the application class:

override fun onCreate() {    
    if (MissingSplitsManagerFactory.create(this).disableAppIfMissingRequiredSplits()) {
        return
    }
    super.onCreate()
}

This check is very easy to implement, and detailed instructions were previously available at https://developer.android.com/guide/app-bundle/sideload-check. There are links to this all over, e.g. in a Realm issue, or at the top of the MissingSplitsManager documentation.

However, this link now redirects to a "Known issues" section, with the very vague:

Partial installs of sideloaded apps—that is, apps that are not installed using the Google Play Store and are missing one or more required split APKs—fail on all Google-certified devices and devices running Android 10 (API level 29) or higher. When downloading your app through the Google Play Store, Google ensures that all required components of the app are installed.

So, what happened? Why is the library's simple check no longer mentioned, even on the documentation for the library.

Perhaps there's some undocumented issue with the library? Perhaps Google don't want to help sideloading at all?

ANSWER

Answered 2020-Mar-10 at 20:28

This library, although convenient, was only a temporary solution until a better solution could be found. This library effectively makes a disk read on every startup of the app, which affects startup latency. Note that this affects all users regardless of whether they have all splits or not, but is only useful for users who sideloaded the app so they'd get a warning message instead of a crash.

The Android platform is now rejecting the installation of apps that don't have all the required splits, rendering the sideloading API unnecessary. This solution should work on all Android versions.
