• dexOptions - allow to load Java AWT for Android。

• dependencies - define dependency files of onbon.bx06 API including JAR and AAR. All files saved in libs folder. Note: file names need to be changed to correct version.

android {
    ...
    defaultConfig {
        ...
        project.ext.set("archivesBaseName", "bx6g.mobiledemo-" + defaultConfig.versionName);
    }
    dexOptions {
        preDexLibraries = false
        additionalParameters =["--core-library"]
    }

}

dependencies {
    ...
    compile files('libs/bx06.message-0.5.0-SNAPSHOT.jar')
    compile files('libs/bx06-0.5.0-SNAPSHOT.jar')

    compile(name:'java.awt4a-0.1-release', ext:'aar')
    ...
}

AndroidManifest.xml

• android:name - setup startup class to initial runtime environment of BX6G API.

• android.permission.INTERNET - allow to use socket.

<application
    android:name="onbon.bx06.mobiledemo.MainApplication"
    ...>
</application>
<uses-permission android:name="android.permission.INTERNET" />

MainApplication.java

Implementation of class which defines at android:name in AndroidManifest.xml.

package onbon.bx06.mobiledemo;

import android.app.Application;

import j2a.awt.AwtEnv;
import onbon.bx06.Bx6GEnv;

public class MainApplication extends Application {

    private boolean initial;

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

        try {
            // java.awt for android initial
            AwtEnv.link(this);                          // link application and AWT
            AwtEnv.configPaintAntiAliasFlag(true);      // setup anti-alias flag.

            // BX6G API initial
            Bx6GEnv.initial();

            this.initial = true;
        }
        catch (Exception ex) {
            this.initial = false;
        }
    }
}

Develop

Screen operation

Because socket client can’t be run on UI thread, all operations execute to the screen need to be run in a new thread.

new Thread(new Runnable() {
    public void run() {
        // operate to screen
    }
}).start();

UI Update

After executing to the screen on non UI thread, use runOnUiThread to callback to UI thread.

runOnUiThread(new Runnable() {
    public void run() {
        // update UI
    }
});
