Question

Hi I am new to android development. I am trying to make my android phone silent using java. After searching google I found some examples but they didnt workd for me. Here is my code.

package com.zafar.silent;

import android.app.Activity;
import android.content.Context;
import android.media.AudioManager;
import android.os.Bundle;

public class Silent extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    AudioManager audiomanage = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
    audiomanage.setRingerMode(AudioManager.RINGER_MODE_SILENT);
}
}

Can someone help me how can I make this run?

Thanks in advance

Update

Here is my menifest file

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.zafar.silent"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk android:minSdkVersion="10" />

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >
    <activity
        android:name=".Silent"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

try this :

 AudioManager audio = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
    audio.setRingerMode(0);

manifest file:

<application>
<uses-permission android:name="android.permission.WRITE_SETTINGS"/>
<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS"/>
</application>
