Realm-java: how to build app with Realm in offline (android)

[ledboot]

in some cases,we develop in offline, so i download realm jar ,put it into project.

error:

Error:(3, 0) Cause: com/neenbedankt/gradle/androidapt/AndroidAptPlugin

Realm is distributed as an AAR since 0.88.0.

So just adding realm.jar won't work.

I think Gradle's offline mode should be able to handle this by default?

[ledboot]

I add android-apt-1.3.jar realm-gradle-plugin-2.1.0.jar realm-transformer-2.1.0.jar into a folder plugin

in build.gradle

buildscript {
    repositories {
        jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.3'
//        classpath "io.realm:realm-gradle-plugin:1.1.0"
        classpath fileTree(dir:'app/plugin',include: ['*.jar'])
    }
}

gradle sync an error:

Error:(3, 0) Failed to apply plugin [id 'realm-android']

[Zhuinden]

But as I asked, doesn't Gradle already handle this if you enable Offline Mode?

I have created a small project in Android Studio, added Realm Java 2.0.2 to the two relevant Gradle files (as outlined in the documentation), and sync the project. After that, I set Gradle offline, and I can build.

@ledboot
If Gradle offline mode is not enough, you can create a local maven repository to fetch the files from. This project here shows how it can be accomplished: http://ge.tt/2axpkVf2

[ledboot]

I was trying to use Realm in offline mode. so,, After gradle succeed, I got following files
realm-annotations-2.0.2.jar
realm-annotations-processor-2.0.2.jar
realm-gradle-plugin-2.0.2.jar
realm-transformer-2.0.2.jar
realm-android-library-2.0.2.aar
in C:\Users\user_name.gradle\caches\modules-2\files-2.1\io.realm

and I moved 3 files (realm-gradle-plugin-2.0.2.jar, realm-transformer-2.0.2.jar, realm-android-library-2.0.2.aar) into libs folder of project and tried to build.

dependencies {
... .... ...
compile fileTree(dir: 'libs', include: ['*.jar'])
compile(name:'realm-android-library-2.0.2', ext:'aar')
}

build is successfull , but app crashes when it running on MyApplication
public class MyApplication extends Application {

@Override
public void onCreate() {
    super.onCreate();

    // Add your initialization code here
    Parse.initialize(new Parse.Configuration.Builder(this)
            .applicationId("E3bTMbxLnMAzuxER2XBSAZWTwcrGe7st95hrxiz1")
            .clientKey("s6lhRSbT5jTXK6thLuK28bdTQAxUEispX50BhUS4")
            .server("https://parseapi.back4app.com/").build()
    );

    Realm.init(this);
    RealmConfiguration config = new RealmConfiguration.Builder().build();
    Realm.setDefaultConfiguration(config);
}

}

Here is log for crash

                                                                       --------- beginning of crash

Realm depends on the ReLinker library so you need to download that too.

@cmelchior The link http://ge.tt/2axpkVf2 is blocked by chrome and any download is automatically flagged as malicious from the site. Firefox doesn't even trigger a download. Can you post the project to another file share? Thanks.

[AppHero2]

@kneth , I added ReLinker library as you told, but another crash issue.
dependencies {
......
compile(name: 'relinker-1.2.2', ext: 'aar')
compile(name:'realm-android-library-2.0.2', ext:'aar')

   public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    mContainer = container;
    View view = inflater.inflate(R.layout.fragment_animate, container, false);

    listView = (ListView) view.findViewById(R.id.fragment_animate_list);

    results = realm.where(GSCAnimation.class).findAll(); >>>>> **crashes on here**

    loadingView = (LoadingView) view.findViewById(R.id.electric_fan_view);
    adapter = new AnimateListAdapter(getActivity(), results);
    listView.setAdapter(adapter);

    });

    return view;
    }

It looks like the annotation processor hasn't been executed. You might have to add @RealmClass to your model classes.
