就是直接获取用户手机中的短信中心号，该种方式需要你的应用满足两个条件，1:你的应用需要有系统签名. 2:你的应用需要和phone进程在同一个进程组。具体实现方式如下:
配置AndroidManifest.xml 文件
<?xml version="1.0" encoding="utf-8"?>
< manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.hello"
android:sharedUserId="android.uid.phone"
android:versionCode="1"
android:versionName="100">
<application android:icon="@drawable/icon"
android:process="com.android.phone"
android:label="@string/app_name">
<activity android:name=".HelloWordActivity"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
具体实现代码如下:
public class HelloWordActivity extends Activity implements Callback
{
private Handler mSmscHandle = null;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
try
{
mSmscHandle = new Handler(this);
getSmsc();
}
catch(Exception e)
{}
}
@SuppressWarnings("unchecked")
public void getSmsc()
{
try
{
//调用PhoneFactory.getDefaultPhone()
Class PhoneFactory = Class.forName("com.android.internal.telephony.PhoneFactory");
Method getDefaultPhone = PhoneFactory.getMethod("getDefaultPhone", (Class[]) null);
Object phone = (Object)getDefaultPhone.invoke(null, (Object[]) null);
Log.i("HELLOWORLD", "phone:" + phone);
//调用Phone.getSmscAddress(Message result)
Class[] ParamType = new Class[1];
ParamType[0] = Message.class;
Message msg = mSmscHandle.obtainMessage(10001);
Object[] paramValue = new Object[1];
paramValue[0] = msg;
Class Phone = Class.forName("com.android.internal.telephony.Phone");
Method getSmscAddress = Phone.getDeclaredMethod("getSmscAddress", ParamType);
getSmscAddress.invoke(phone, paramValue);
}
catch( Exception e )
{
showTrace(e);
}
}
public boolean handleMessage(Message msg)
{
// TODO Auto-generated method stub
Log.i("HELLOWORLD", "handleMessage() msg.what:" + msg.what
+ " data:" + msg.peekData()
+ " result:" + msg.obj.toString());
if(10001 == msg.what)
{
dealSmscResult(msg.obj);
}
return false;
}
private void dealSmscResult(Object asyncResult)
{
try
{
Field exception = asyncResult.getClass().getDeclaredField("exception");
Throwable throwable = (Throwable)exception.get(asyncResult);
Field result = asyncResult.getClass().getDeclaredField("result");
Object myResult = result.get(asyncResult);
if(null != myResult)
{
Log.i("HELLOWORLD", "dealSmscResult() result:" + myResult.toString());
String szResult = (String)myResult;
String szAddr = szResult.split(",")[0];
Log.i("HELLOWORLD", "dealSmscResult() smsc:" + szAddr);
}
if(null != throwable)
{
Log.i("HELLOWORLD", "dealSmscResult() throwable:" + throwable.getMessage());
}
}
catch(Exception e)
{
showTrace(e);
}
}
}
代码比较简单，就是调用两个两个隐藏的com.android.internal.telephony.PhoneFactory，
om.android.internal.telephony.Phone 就能获取本机的短信中心号码。
之后还需要使用android源码包中 platform.pk8 platform.x509.pem 两个文件(build\target\product\security 目录下)对生成的apk签名;否则无法安装在手机上。签名的命令为
java -jar signapk.jar platform.x509.pem platform.pk8 HelloWord.apk HelloWordSign.apk
