Error?

[KAMAKAILAN]

I'm trying to run the the example project but when launched it immediately exit or close, I already input the API Key. initialization failed: easyar sense (android-arm64) invalid key: invalid format

[PiotrMitkowski]

Hello @KAMAKAILAN! Could you share your AndroidManifest file, where you provide the API key? Ideally with the first 5 characters of the key, so it doesn't leak.

[KAMAKAILAN]

Hello, thank you for your reply. Here's the AndroidManifest file. It's the same with the example project on AR_quido plugin. [image: image.png] D:\CAPSTONE\ar\AR_quido\example\android\app\src\main\AndroidManifest.xml <about:blank#blocked>

@KAMAKAILAN unfortunately I can't see the attached screenshot, as it seems to be linked as a file from your local machine's storage. Could you paste its contents in the comment, ideally formatted as the code (using ``` characters).

The error that you've mentioned usually means, that the key and/or the app's package name are invalid. I wanted to make sure that it isn't your case.

[KAMAKAILAN]

I don't know if what I did was right, so I would like to make a request. Can you make a tutorial on how to use this plugin and the Easy AR Sense :< it's my first time self studying AR and I think it has something that existing plugin ARCore doesn't have and it's the image recognition like the ARKit. I would like to use these plugin in our Capstone study.

Anyway, here's my AndroidManifest file:

<manifest xmlns:android="http://schemas.android.com/apk/res/android">
        <uses-feature
                android:name="android.hardware.camera"
                android:required="false" />
        <uses-permission android:name="android.permission.CAMERA"/>
        <application
        android:label="ar_quido_self"
        android:name="${applicationName}"
        android:icon="@mipmap/ic_launcher">
        <activity
            android:name=".MainActivity"
            android:exported="true"
            android:launchMode="singleTop"
            android:theme="@style/LaunchTheme"
            android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
            android:hardwareAccelerated="true"
            android:windowSoftInputMode="adjustResize">
            <!-- Specifies an Android theme to apply to this Activity as soon as
                 the Android process has started. This theme is visible to the user
                 while the Flutter UI initializes. After that, this theme continues
                 to determine the Window background behind the Flutter UI. -->
            <meta-data
              android:name="io.flutter.embedding.android.NormalTheme"
              android:resource="@style/NormalTheme"
              />
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
        <!-- Don't delete the meta-data below.
             This is used by the Flutter tool to generate GeneratedPluginRegistrant.java -->
        <meta-data
            android:name="flutterEmbedding"
            android:value="2" />
            <meta-data
           android:name="com.miquido.ar_quido.f1bb1****"
           android:value="f1bb1****" />
    </application>
</manifest>

and the app won't launch and what shows in debug console are:

I don't know if what I did was right, so I would like to make a request. Can you make a tutorial on how to use this plugin and the Easy AR Sense :<

I'll try to prepare a detailed guide about it, but it might take same time, so please be patient :)

Anyway, here's my AndroidManifest file:

Thanks for sharing it! If I see correctly, you declared the meta-data tag with the API key as following:

<meta-data
    android:name="com.miquido.ar_quido.f1bb1****"
    android:value="f1bb1****" />

It should look as follows (assuming, that f1bb1**** represents your API key):

<meta-data
    android:name="com.miquido.ar_quido.API_KEY"
    android:value="f1bb1****" />

android:name attribute should always remain unchanged, only the android:value should be filled with your API key. I'll add it to the docs in README, since it isn't very clear 😉 Let me know if that fixes your issue.

[KAMAKAILAN]

I'm looking forward for the tutorial, by the way, I changed it again and still encounter an error.

[PiotrMitkowski]

Hello @KAMAKAILAN! Thanks for your patience.

I think I have another clue, that might fix your problem. I assume that you're using a key from "Authorization" > "API Key" section. Instead, please generate the key in the "Authorization" > "Sense Authorization" section. When creating the key there, ensure you're providing the correct Android Package Name (iOS Bundle ID isn't that important, because ar_quido doesn't use EasyAR on iOS). From logs I see, that it will be com.example.ar_quido_self.

Please let me know, if using "Sense Authorization" key fixes your issue.

[KAMAKAILAN]

It works! The app launched, the camera works and it can detect the referenced image! I appreciate your effort for helping me. May I know the extent of this app? Like how can I project 3D objects or images.

[PiotrMitkowski]

@KAMAKAILAN at this point the plugin handles only a simple use - it detects objects based on the provided images. We didn't have much opportunity to discover other use cases. If you're missing any features in the plugin, feel free to submit an issue with the description of your use case. It will help us improve the plugin

I assume that the problem mentioned in this issue is solved, so I'll update the documentation and close the issue afterward.
