发送手机短信

// 发送短信给安全号码SmsManager smsManager = SmsManager.getDefault();smsManager.sendTextMessage(phone, null,"sim card changed!", null, null);

设置接受广播的优先级最高也就是inter里面的最大值。你可以看api,然后转化为十进制。应该是这个 2147483647。

<receiver android:name=".receiver.SmsReceiver" >            <intent-filter android:priority="2147483647" >                <action android:name="android.provider.Telephony.SMS_RECEIVED" />            </intent-filter>        </receiver>

播放一些小聲音

// 播放报警音乐, 即使手机调为静音,也能播放音乐, 因为使用的是媒体声音的通道,和铃声无关                MediaPlayer player = MediaPlayer.create(context, R.raw.ylzs);                player.setVolume(1f, 1f);                player.setLooping(true);                player.start();

短信的广播接受者

选择最优定位定位

package com.itheima52.mobilesafe.service;import android.app.Service;import android.content.Intent;import android.content.SharedPreferences;import android.location.Criteria;import android.location.Location;import android.location.LocationListener;import android.location.LocationManager;import android.os.Bundle;import android.os.IBinder;/** * 获取经纬度坐标的service *  * @author Kevin *  */public class LocationService extends Service {    private LocationManager lm;    private MyLocationListener listener;    private SharedPreferences mPref;    @Override    public IBinder onBind(Intent intent) {        return null;    }    @Override    public void onCreate() {        super.onCreate();        mPref = getSharedPreferences("config", MODE_PRIVATE);        lm = (LocationManager) getSystemService(LOCATION_SERVICE);        // List<String> allProviders = lm.getAllProviders();// 获取所有位置提供者        // System.out.println(allProviders);        Criteria criteria = new Criteria();        criteria.setCostAllowed(true);// 是否允许付费,比如使用3g网络定位        criteria.setAccuracy(Criteria.ACCURACY_FINE);        String bestProvider = lm.getBestProvider(criteria, true);// 获取最佳位置提供者        listener = new MyLocationListener();        lm.requestLocationUpdates(bestProvider, 0, 0, listener);// 参1表示位置提供者,参2表示最短更新时间,参3表示最短更新距离    }    class MyLocationListener implements LocationListener {        // 位置发生变化        @Override        public void onLocationChanged(Location location) {            System.out.println("get location!");            // 将获取的经纬度保存在sp中            mPref.edit()                    .putString(                            "location",                            "j:" + location.getLongitude() + "; w:"                                    + location.getLatitude()).commit();            stopSelf();//停掉service        }        // 位置提供者状态发生变化        @Override        public void onStatusChanged(String provider, int status, Bundle extras) {            System.out.println("onStatusChanged");        }        // 用户打开gps        @Override        public void onProviderEnabled(String provider) {            System.out.println("onProviderEnabled");        }        // 用户关闭gps        @Override        public void onProviderDisabled(String provider) {            System.out.println("onProviderDisabled");        }    }    @Override    public void onDestroy() {        super.onDestroy();        lm.removeUpdates(listener);// 当activity销毁时,停止更新位置, 节省电量    }}

监听输入框文字变化

// 监听EditText的变化        etNumber.addTextChangedListener(new TextWatcher() {            // 文字 发生变化时的回调            @Override            public void onTextChanged(CharSequence s, int start, int before,                    int count) {                String address = AddressDao.getAddress(s.toString());                tvResult.setText(address);            }            // 文字变化前的回调            @Override            public void beforeTextChanged(CharSequence s, int start, int count,                    int after) {            }            // 文字变化结束之后的回调            @Override            public void afterTextChanged(Editable s) {            }        });
