    <uses-feature android:glEsVersion="0x00030000" android:required="true" />

   <application
       ...
     <activity android:name=".MainActivity">
   
       <meta-data android:name="com.google.ar.core" android:value="required" />
       <intent-filter>
           <action android:name="android.intent.action.MAIN" />
   
           <category android:name="android.intent.category.LAUNCHER" />
       </intent-filter>

2. I have used gadle file like bellow

   apply plugin: 'com.android.application'
   apply plugin: 'com.google.ar.sceneform.plugin'
    android {
      compileSdkVersion 29
      buildToolsVersion "29.0.2"
      defaultConfig {
      applicationId "com.example.sceneform_ar"
      minSdkVersion 15
      targetSdkVersion 26           
      testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
     }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
       targetCompatibility JavaVersion.VERSION_1_8
     }
   
    }
   
   dependencies {    
       androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
       implementation 'com.google.ar.sceneform.ux:sceneform-ux:1.12.0'
   
      }
   
   sceneform.asset('sampledata/models/bear.fbx',
        'default',
       'sampledata/models/bear.sfa',
        'src/main/res/raw/bear')
   

3. In in activity xml I have used bellow code..

      <fragment android:name="com.google.ar.sceneform.ux.ArFragment"
       android:id="@+id/ux_fragment"
       android:layout_width="match_parent"
       android:layout_height="match_parent" />
   

4. I have used bellow code in MainActivity

       ModelRenderable.builder()
           .setSource(this, R.raw.bear)
           .build()
           .thenAccept(renderable -> bearRenderable = renderable)
           .exceptionally(
                   throwable -> {
                       Log.e("Errror***** >", "Unable to load Renderable.", throwable);
                       return null;
                   });
   

   What is the wrong with it? I don't know. Can you please help me to solve the problem

Answer 1

Silly mistake I have used bellow code inside MainActivity

<meta-data android:name="com.google.ar.core" android:value="required" />

My manifest will be..

 <application
......">

    <meta-data android:name="com.google.ar.core" android:value="required" />

    <activity android:name=".MainActivity">

        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>
