Android MTK平台 实现用命令写手机IMEI号

涉及内容：

1. 获取Phone对象；

2. AT command；

3.Java正则表达式；

实现思路：

从拨号盘输入含有IMEI号的字串，提取字串中的IMEI，通过Intent，将IMEI号传入写IMEI号的Activity。

*************************************************************************************

1. 获取Phone对象；

刚开始想在拨号盘的应用中获取Phone对象耗费了很多时间，还是没有搞定，

最后不得不另写一个APK来完成写IMEI号的功能。如有朋友知道如何在任何文件中获取Phone对象，麻烦告知。

关于AndroidManifest.xml：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.wirteimei"
	android:sharedUserId="android.uid.phone" //必须包含该属性
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="15" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity android:name=".MainActivity"
			android:process="com.android.phone" //必须包含该属性

            android:label="@string/title_activity_main" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
               <!-- <category android:name="android.intent.category.LAUNCHER" /> -->
            </intent-filter>
        </activity>
    </application>

</manifest>

另需使用platform给Apk签名；

有了上述条件，下面就是实现写IMEI号的功能了。

2. 写IMEI号

a. 获取IMEI号；

通过拨号盘获取输入的Imei号，例如在拨号盘输入一组特定形式的字串，形式如*#123456789012345#6666#，

然后实现对该类型字串的检测，这里使用的是正则表达式；

private static final String PATTERN_IMEI_CMD = "^\\*\\#\\d{15}\\#6{4}\\#$";//检测是否是写IMEI号的字串
private static final String PATTERN_IMEI_VALUE = "\\d{15}";//提取IMEI号

Pattern pattern = Pattern.compile(PATTERN_IMEI_CMD);
		Matcher matcher = pattern.matcher(input);
		if(matcher.matches()){
			Pattern pn = Pattern.compile(PATTERN_IMEI_VALUE);
			Matcher mc = pn.matcher(matcher.group());
			String imeiString = "";
			while(mc.matches()){
				imeiString = mc.group();
			}
			
			Log.d(TAG,"_______________imeiString = "+ imeiString);
			if(imeiString == null || imeiString.isEmpty()){
				return false;
			}
			Intent it = new Intent();
			it.setClassName("com.example.writeimei", "com.example.writeimei.MainActivity");
			it.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
			it.putExtra("IMEI_STRING", imeiString);
			context.startActivity(it);
		}

b.写入IMEI号；

写入IMEI号的Activity,MainActivity.java:

package com.example.wirteimei;

import java.util.regex.Matcher;
import java.util.regex.Pattern;

import com.android.internal.telephony.Phone;
import com.android.internal.telephony.PhoneFactory;

import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.content.DialogInterface.OnClickListener;
import android.content.Intent;
import android.os.AsyncResult;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.util.Log;


public class MainActivity extends Activity {

	private static final int EVENT_WRITE_IMEI = 7;
	private static final String TAG = "MainActivity";
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Intent intent = getIntent();
        String imeiString = intent.getStringExtra("IMEI_STRING");

        Log.d(TAG,"____imeiString = "+imeiString);
        String[] ImeiString = new String[2];

	//AT Command
        ImeiString[0] = "AT+EGMR=1,7,\"" + imeiString + "\"";//single sim card
        Phone phone = PhoneFactory.getDefaultPhone();//获取Phone对象
        phone.invokeOemRilRequestStrings(ImeiString, new WriteImeiHandler().obtainMessage(EVENT_WRITE_IMEI));//发送更新IMEI号AT command
    }
    
    private String getImeiString(String input){
    	Pattern pattern = Pattern.compile("^\\*\\#\\d{15}\\#6{4}\\#$");
    	Matcher matcher = pattern.matcher(input);
    	while(matcher.matches()){
    		Pattern pattern1 = Pattern.compile("\\d{15}");
    		Matcher matcher1 = pattern1.matcher(matcher.group());
    		while(matcher1.find()){
    			return matcher1.group();
    		}
    	}
    	return null;
    }
    
    class WriteImeiHandler extends Handler{
    	BtnClickListener mListener = new BtnClickListener();
    	
    	public void handleMessage(Message message){
    		AsyncResult ar = (AsyncResult)message.obj;
    		switch(message.what){
    		case EVENT_WRITE_IMEI:
    			if (ar.exception == null) {
                	AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
    				builder.setTitle("IMEI WRITE");
    				builder.setMessage("The IMEI is writen successfully.");
    				builder.setPositiveButton("OK" , mListener);
    				builder.setCancelable(false);
    				builder.create().show();
                } else {
                	AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
    				builder.setTitle("IMEI WRITE");
    				builder.setMessage("Fail to write IMEI due to radio unavailable or something else.");
    				builder.setPositiveButton("OK" , mListener);
    				builder.setCancelable(false);
    				builder.create().show();
                }
    		}
    	}
    }
    
    class BtnClickListener implements DialogInterface.OnClickListener{
    	public void onClick(DialogInterface dialog, int which){
    		MainActivity.this.finish();
    	}
    }
    
}
