Fatal exception error in Android Studio with imported Unity project

Question

I am running into a "Fatal exception error" in Android Studio. I have created an app, that when a button is clicked is supposed to launch a unity project that I have imported into Android Studio in a .aar format. It's throwing a Fatal exception error that I am unsure of how to solve. The app launches fine but when I press the button it crashes. The logcat print out is below:

2020-05-05 21:41:00.748 24376-24422/com.jonathan.vrtest3 D/OSTracker: OS Event: crash

And my main_activity.java is:

package com.jonathan.vrtest3;

import androidx.appcompat.app.AppCompatActivity;

import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

import com.unity3d.player.UnityPlayerActivity;

public class MainActivity extends AppCompatActivity {


    public static final String EXTRA_LOC_ID = "arguments";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        //final Intent intent = new Intent(this, UnityPlayerActivity.class);



        ((Button) findViewById(R.id.button)).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                Intent intent = new Intent(MainActivity.this, UnityPlayerActivity.class);

                startActivity(intent);
            }
        });
    }
}

And my manifest file:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.jonathan.vrtest3">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

</manifest>

Any help would be greatly appreciated!

SOLVED: following this solution, adding <string name="game_view_content_description">Game view</string> to my strings.xml file solved the issue. I used this tutorial — Overture, Commented May 15, 2020 at 11:20

Your manifest is missing the activity, change it to:

AndroidManifest.xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.jonathan.vrtest3">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name="com.unity3d.player.UnityPlayerActivity" >
            <intent-filter>
                <action android:name="android.intent.action.DEFAULT" />
            </intent-filter>
        </activity>
        <activity android:name=".GameActivity"/>
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

</manifest>

and start the unity activity from another activity by chaining the intent with:

GameActivity.java:

class GamesActivity extends AppCompatActivity {

    @Override
    public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState) {
    super.onCreate(savedInstanceState, persistentState);

    Intent intent = new Intent(this, UnityPlayerActivity.class);
    startActivity(intent);
}

}

Hi! Try this instead and not starting it from the Main activity, silly temp solution at the moment but this seemed to work for me. Haven't had time to deep dive why this issue occurs

Separate file in the same folder as the MainActivity. Note the added activity in the manifest

Forgot to change the kotlin code to java, post updated!

so in your mainactivity do Intent intent = new Intent(this, GameActivity.class) instead. Note that this is just a temp workaround and not a solution

Did you add the intent in the gameactivity?
