本文介绍了AndroidManifest、BroadcastReceiver、测试设置类和XML布局文件的使用，详细展示了如何创建和配置Android应用的基本组件。

直接看代码：

AndroidManifest

        <activity android:name="TestingSettings" android:label="@string/testing">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>

        <receiver android:name="TestingSettingsBroadcastReceiver">
            <intent-filter>
                 <action android:name="android.provider.Telephony.SECRET_CODE" />
                 <data android:scheme="android_secret_code" android:host="4636" />
            </intent-filter>
       </receiver>

TestingSettingsBroadcastReceiver.java

package com.android.settings;

import android.provider.Telephony;
import static android.provider.Telephony.Intents.SECRET_CODE_ACTION;

import android.content.Context;
import android.content.Intent;
import android.content.BroadcastReceiver;
import android.util.Config;
import android.util.Log;
import android.view.KeyEvent;


public class TestingSettingsBroadcastReceiver extends BroadcastReceiver {
  
    public TestingSettingsBroadcastReceiver() {
    }
    
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(SECRET_CODE_ACTION)) {
            Intent i = new Intent(Intent.ACTION_MAIN);
            i.setClass(context, TestingSettings.class);
            i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(i);
        }
    }
}

TestSettings.java

package com.android.settings;

import android.os.Bundle;
import android.preference.PreferenceActivity;

public class TestingSettings extends PreferenceActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        
        addPreferencesFromResource(R.xml.testing_settings);
    }

}
