[android] 手机卫士绑定sim卡详解手机开发

收不到启动广播，查看知乎，好像是说高版本的系统都禁止了

还可以通过adb发送开机广播

adb shell am broadcast -a android.intent.action.BOOT_COMPLETED

还没测试，回去再测试

========================== 

读取sim卡的序列号，保存起来，一旦sim发生变更了，认为是小偷的sim卡，发出警告

读取sim卡序列号

获取TelephonyManager对象，通过getSystemService(TELEPHONY_SERVICE)

调用TelephonyManager对象的getSimSerialNumber()方法，得到String类型的序列号

把序列号保存在SharedPreences里面

需要加权限 android.permission.READ_PHONE_STATE

检测sim卡是否变更

使用广播接收者，监听手机的开机广播

新建一个包 xxx.receiver，新建一个类BootCompleteReceiver.java

清单文件注册一下，添加 receiver 节点，设置名称android:name=”xxx”

添加意图过滤器 intent-filter 节点

添加动作 action/ 节点，设置监听动作名称android.intent.action.BOOT_COMPLETED

在BootCompleteReceiver类里面的onReceive()方法里，接收到广播，读取当前的sim卡序列号，比较之前保存的sim卡序列号，如果不一样就发送短信给安全号码

监听开机启动需要权限 android:perission.RECEIVE_BOOT_COMPLETED

BootCompleteReceiver.java

package com.qingguow.mobilesafe.receiver; 

import android.content.BroadcastReceiver; 

import android.content.Context; 

import android.content.Intent; 

import android.content.SharedPreferences; 

import android.telephony.TelephonyManager; 

import android.widget.Toast; 

public class BootCompleteReceiver extends BroadcastReceiver { 

 private TelephonyManager tm; 

 private SharedPreferences sp; 

 @Override 

 public void onReceive(Context cotext, Intent arg1) { 

 sp=cotext.getSharedPreferences("config", Context.MODE_PRIVATE); 

 //读取当前的sim卡序列号 

 tm=(TelephonyManager) cotext.getSystemService(Context.TELEPHONY_SERVICE); 

 String relSim=tm.getSimSerialNumber(); 

 //读取之前保存的 

 String saveSim=sp.getString("sim", ""); 

 //判断后发短信 

 if(saveSim.equals(relSim)){ 

 }else{ 

 //发送报警短息给安全号码 

 System.out.println("sim卡变更了"); 

 Toast.makeText(cotext, "sim卡变更了", 1).show(); 

}

SecGuide2Activity.java

package com.qingguow.mobilesafe; 

import android.content.Intent; 

import android.content.SharedPreferences; 

import android.content.SharedPreferences.Editor; 

import android.os.Bundle; 

import android.telephony.TelephonyManager; 

import android.text.TextUtils; 

import android.view.View; 

import android.view.View.OnClickListener; 

import com.qingguow.mobilesafe.ui.SettingItemView; 

public class SecGuide2Activity extends BaseSecGuideActivity { 

 private SettingItemView siv_sim; 

 private SharedPreferences sp; 

 private TelephonyManager telephonyManager; 

 @Override 

 protected void onCreate(Bundle savedInstanceState) { 

 super.onCreate(savedInstanceState); 

 setContentView(R.layout.activity_lost_find2); 

 siv_sim = (SettingItemView) findViewById(R.id.siv_sim); 

 sp = getSharedPreferences("config", MODE_PRIVATE); 

 telephonyManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE); 

 // 根据保存的数据设置状态 

 String sim = sp.getString("sim", ""); 

 if (TextUtils.isEmpty(sim)) { 

 siv_sim.setChecked(false); 

 } else { 

 siv_sim.setChecked(true); 

 // 绑定sim卡 

 siv_sim.setOnClickListener(new OnClickListener() { 

 @Override 

 public void onClick(View arg0) { 

 String sim = telephonyManager.getSimSerialNumber(); 

 Editor editor = sp.edit(); 

 String simSp = sp.getString("sim", ""); 

 if (TextUtils.isEmpty(simSp)) { 

 siv_sim.setChecked(true); 

 editor.putString("sim", sim); 

 } else { 

 siv_sim.setChecked(false); 

 editor.putString("sim", ""); 

 editor.commit(); 

 }); 

 public void nextStep(View v) { 

 showNext(); 

 public void preStep(View v) { 

 showPre(); 

 @Override 

 public void showNext() { 

 Intent intent = new Intent(this, SecGuide3Activity.class); 

 startActivity(intent); 

 finish(); 

 @Override 

 public void showPre() { 

 Intent intent = new Intent(this, SecGuide1Activity.class); 

 startActivity(intent); 

 finish(); 

}
