不说啥了：代码来自于 $ANDROID_SOURCE/packages/apps/Settings 

 

AndroidManifest.xml

"TestingSettings" android:label="@string/testing">

"android.intent.action.MAIN"/>
"android.intent.category.DEFAULT"/>


"TestingSettingsBroadcastReceiver">

"android.provider.Telephony.SECRET_CODE"/>
"android_secret_code" android:host="4636"/>

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);
        }
    }
}

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);
    }

}
