Wikitude

Hi,

Using the example for SDK 7 on  Android Studio 2.3 

Was unable to open the camera although the code works with WIkitude Logo appearing.

Please see below.

public class MainActivity extends AppCompatActivity {

    public ArchitectView architectView;

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        WebView.setWebContentsDebuggingEnabled(true);

        this.architectView = new ArchitectView(this);

        final ArchitectStartupConfiguration config = new ArchitectStartupConfiguration();

        config.setLicenseKey("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");

// config.setCameraPosition("back"); // The default camera is the first camera available for the system.

// config.setCameraResolution(sampleData.getCameraResolution()); // The default resolution is 640x480.

// config.setCameraFocusMode(sampleData.getCameraFocusMode()); // The default focus mode is continuous focusing.

// config.setCamera2Enabled(sampleData.isCamera2Enabled()); // The camera2 api is disabled by default (old camera api is used).

// config.setFeatures(sampleData.getArFeatures()); // This tells the ArchitectView which AR-features it is going to use, the default is all of them.

        this.architectView.onCreate( config );

        setContentView(architectView);

    }

    @Override

    protected void onPostCreate(@Nullable Bundle savedInstanceState) {

        super.onPostCreate(savedInstanceState);

        this.architectView.onPostCreate();

        try {

            //If authorisation not granted for camera

            if (ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED)

                ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CAMERA}, 50);

            this.architectView.load( "01_ImageTracking_2_DifferentTargets/index.html" );

        } catch(Exception ex ) {

            ex.printStackTrace();

        }

    }

}

Hello! 

I have the same problem with my android app. Black screen and wikitude logo only. I then have to go to my divice's settings to give permission but I don't like that. 

I added on the AndroidManifest the line 

<uses-feature android:name="android.hardware.camera" android:required="true" />

but I don't have any file in my project with the name MainActivity.java and I do not have good knowledge of coding.
Can you help me? I am using Unity with Wikitude.

hi YT,

I also face the problem with you. I can't access the camera permission. When I code the ArchitectView.onResume, my apps cannot be run. I don't know how to solve. Can you please help me?

Hi Alex, 

Thanks! Works great and thanks for the activity life cycle tip!

A few of my customers use AR as a sales tool and sometimes do not have access to wifi at the customers factory.  As such need to offer the option of storing the content in the cache after they have downloaded and viewed the content in a wifi environment.

Do you you have any tips as to how to realise this?

Also, should I be starting a new topic for item?

Thanks again!

Hi Alex,

Thanks.  Obviously my snippets are not too good.

But Yes, that is added.  And we can see the wikitude logo on the dark screen but unable to see the camera feed.

Attached is the for your perusal.

Thanks.
