我已将Unity项目导出为android工作室项目。我在android studio中导入了该项目。我创建了一个活动，我想从该活动中启动UnityplayerActivity。但它给了我一个例外。
Main2Activity.java
package com.ultimate;
import android.content.Intent;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.widget.Button;
import com.unity3d.player.UnityPlayer;
public class Main2Activity extends AppCompatActivity {
Button button;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
Intent intent = new Intent(getApplicationContext(),com.ultimate.UnityPlayerActivity.class);
startActivity(intent);
}
});
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
}
}

答案 0 :(得分：2)
我已经解决了这个问题。
您必须在UnityPlayerActivity文件中添加AndroidManifest.xml。
