1.下载XposedBridgeApi-20150213.jar文件，右键添加到构建路径，这个包是不需要导出的！

2.在AndroidManifest.xml里添加三个meta-data数据

package="cn.zhg.notrack"

android:installLocation="internalOnly"

android:versionCode="1"

android:versionName="1.0.0" >

android:minSdkVersion="15"

android:targetSdkVersion="21" />

android:anyDensity="true"

android:largeScreens="true"

android:normalScreens="true"

android:resizeable="true"

android:smallScreens="true"

android:xlargeScreens="true" />

android:allowBackup="false"

android:icon="@drawable/ic_launcher"

android:label="@string/app_name"

android:logo="@drawable/ic_launcher"

android:theme="@style/CustomTheme.Light" >

android:name="xposedmodule"

android:value="true" />

android:name="xposedminversion"

android:value="54" />

android:name="xposeddescription"

android:value="@string/app_description" />

android:name=".MainActivity"

android:configChanges="keyboardHidden|orientation|screenSize"

android:label="@string/app_name"

android:launchMode="singleTop" >

3.在Activity中使用SharedPreferences保存修改自定义的数据

public class MainActivity extends Activity

{

private TelephonyManager phone;

/**IMEI修改输入框*/

private EditText imeitx;

protected void onCreate(Bundle savedInstanceState)

{

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

phone = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);

imeitx=(EditText)this.findViewById(R.id.imei);

}

public boolean onCreateOptionsMenu(Menu menu)

{

getMenuInflater().inflate(R.menu.main, menu);

return true;

}

public boolean onOptionsItemSelected(MenuItem item)

{

int id = item.getItemId();

if (id == R.id.action_save)

{

//保存数据

saveData();

return true;

}

return super.onOptionsItemSelected(item);

}

/**

* 使用SharedPreferences保存数据

*/

private void saveData()

{

try

{

SharedPreferences sh = this.getSharedPreferences("prefs",

Context.MODE_WORLD_READABLE);

Editor pre = sh.edit();

Logger.d("保存内容");

pre.putString("imei", imeitx.getText().toString());

pre.apply();

} catch (Throwable e)

{

Logger.d("写入内容失败");

e.printStackTrace();

}

}

protected void onResume()

{

super.onResume();

//读取当前设备的IMEI

imeitx.setText(phone.getDeviceId());

}

}

4.在assets创建xposed_init文件，，指定Xposed Hook入口类

cn.zhg.notrack.MainHook

5.MainHook实现IXposedHookLoadPackage接口的handleLoadPackage方法，使用XSharedPreferences获取保存的数据，XposedHelpers注入监听TelephonyManager#getDeviceId方法

public class MainHook implements IXposedHookLoadPackage

{

public void handleLoadPackage(LoadPackageParam lpparam) throws Throwable

{

XSharedPreferences pre = new XSharedPreferences(this.getClass()

.getPackage().getName(), "prefs");

HookMethod(TelephonyManager.class, "getDeviceId",

pre.getString("imei", null));

}

private void HookMethod(final Class cl, final String method,

final String result)

{

try

{

XposedHelpers.findAndHookMethod(cl, method,

new Object[] { new XC_MethodHook()

{

protected void afterHookedMethod(MethodHookParam param)

throws Throwable

{

param.setResult(result);

}

} });

} catch (Throwable e)

{

Logger.d("修改" + method + "失败!" + e.getMessage());

}

}

}

6.在android sdk build-tools 21.0.1下可能遇到由于assets产生Command-line Error -1073741819的问题，升级一下android sdk build-tools就行了。
