Android Studio 使用隐式intent，运行程序后一直在循环，无法跳转，请大神指导

AndroidManifest.xml的代码
<?xml version="1.0" encoding="utf-8"?>
xmlns:tools="http://schemas.android.com/tools"
package="cn.edu.jssvc.activitytest">

<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=".SecondActivity" />

    <activity
        android:name=".FirstActivity"
        tools:ignore="ExtraText,MissingClass">
        android:label="This is FirstActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
            <action android:name="com.example.activitytest.ACTION_START" />
            <category android:name="android.intent.category.DEFAULT" />

        </intent-filter>

    </activity>
</application>

FirstActivity.java的代码

import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;

public class FirstActivity extends AppCompatActivity {

@Override

    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(@NonNull MenuItem item) {
    switch (item.getItemId()) {
        case R.id.add_item:
            Toast.makeText(this, "You clicked Add", Toast.LENGTH_SHORT).show();
            break;
        case R.id.remove_item:
            Toast.makeText(this, "You clicked Remove", Toast.LENGTH_SHORT).show();
            break;
        default:
    }
    return true;
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.first_layout); //load resources
    Button button1 = (Button) findViewById(R.id.button_1);
    button1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent("com.example.activitytest.ACTION_START");
            startActivity(intent);
        }
    });
