我想在android中编写一个服务，它将跟踪传出呼叫和后台短信。每当收到拨出电话事件或拨出短信事件时，我都想获取电话号码，日期，通话时长（如果是拨出电话）以及通话或短信费用等详细信息。我想将这些细节保存在本地数据库中。
我尝试使用广播接收器和服务，但我无法计算实际呼叫持续时间。对于SMS我发现我们需要在某个特定时间段后检查SMS文件夹是否更新。是否有任何事件会在发送短信后通知。
以下是我迄今为止尝试过的守则 -
我的MainActivity.java
public class MainActivity extends Activity {
TextView call = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
call = (TextView) findViewById(R.id.call);
Intent intent = new Intent(this, HelloService.class);
startService(intent);
}
}
我的服务类
public class HelloService extends Service {
CallDurationReceiver receiver = null;
@Override
public void onCreate() {
receiver = new CallDurationReceiver();
IntentFilter filter = new IntentFilter();
filter.addAction("android.provider.Telephony.SMS_RECEIVED");
filter.addAction(android.telephony.TelephonyManager.ACTION_PHONE_STATE_CHANGED);
registerReceiver(receiver, filter);
HandlerThread thread = new HandlerThread("ServiceStartArguments");
thread.start();
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
Toast.makeText(this, "service starting", Toast.LENGTH_SHORT).show();
// If we get killed, after returning from here, restart
return START_STICKY;
}
@Override
public IBinder onBind(Intent intent) {
// We don't provide binding, so return null
return null;
}
@Override
public void onDestroy() {
unregisterReceiver(receiver);
Toast.makeText(this, "service done", Toast.LENGTH_SHORT).show();
}
}
我的广播接收器 -
public class CallDurationReceiver extends BroadcastReceiver {
// instance variables of sharedpreferences
SharedPreferences mSharedPrefernce;
Editor e;
// String variables for number,date,time,calltype
String number, date, time, calltype;
long startTime, endTime;
@Override
public void onReceive(final Context context, Intent intent) {
Log.v("info", "calls info....");
// initialising the sharedpreferences
mSharedPrefernce = context.getSharedPreferences("MyPref", 0);
e = mSharedPrefernce.edit();
Bundle bundle = intent.getExtras();
if (bundle == null)
return;
// initialising the variables
number = null;
startTime = 0;
endTime = 0;
// getting incoming call details
String state = bundle.getString(TelephonyManager.EXTRA_STATE);
if ((state != null)
&& (state
.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_RINGING))) {
Log.v("info", "Phone Ringing..");
number = bundle.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
Log.v("info", "Incomng Number: " + number);
calltype = "Incoming";
Time today = new Time(Time.getCurrentTimezone());
today.setToNow();
date = today.monthDay + "-" + (today.month + 1) + "-" + today.year;
time = today.format("%k:%M:%S");
// putting the values into the SharedPreferences
e.putString("number", number);
e.putString("Type", calltype);
e.putString("date", date);
e.putString("time", time);
e.commit();
Toast.makeText(
context,
"Detect Calls sample application\nIncoming number: "
+ number, Toast.LENGTH_SHORT).show();
}
// getting outgoing call details
else if (state == null) {
number = bundle.getString(Intent.EXTRA_PHONE_NUMBER);
Log.v("info", "Outgoing Number: " + number);
calltype = "Outgoing";
Time today = new Time(Time.getCurrentTimezone());
today.setToNow();
date = today.monthDay + "-" + (today.month + 1) + "-" + today.year;
time = today.format("%k:%M:%S");
// putting the values into the SharedPreferences
e.putString("number", number);
e.putString("Type", calltype);
e.putString("date", date);
e.putString("time", time);
e.commit();
Toast.makeText(
context,
"Detect Calls sample application\nOutgoing number: "
+ number, Toast.LENGTH_SHORT).show();
}
// called when the call is answered
else if (state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_OFFHOOK)) {
Log.v("info", "Call Ansered..");
startTime = System.currentTimeMillis();
e.putLong("start", startTime);
e.commit();
}
// called when the call is ended
else if (state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_IDLE)) {
Log.v("info", "Call Ended..");
String phonenumber=null, type=null, date1=null, time1=null, duration=null;
// getting the values from the SharedPreferences
phonenumber = mSharedPrefernce.getString("number", "");
type = mSharedPrefernce.getString("Type", "");
date1 = mSharedPrefernce.getString("date", "");
time1 = mSharedPrefernce.getString("time", "");
long start=0;
start = mSharedPrefernce.getLong("start", 0);
Log.v("info", "startTime=" + start);
// clearing the SharedPreferences
mSharedPrefernce.edit().clear();
endTime = System.currentTimeMillis();
Log.v("info", "endTime=" + endTime);
long totalTime =0;
totalTime = endTime - start;
DateFormat df = new SimpleDateFormat("HH':'mm':'ss");
df.setTimeZone(TimeZone.getTimeZone("GMT+0"));
duration = df.format(new Date(totalTime));
System.out.println("GOT SOMETHING - "+phonenumber + " " + date1 + " " + time1 + " " + duration + " " + type);
Toast.makeText(context, phonenumber + " " + date1 + " " + time1 + " " + duration + " " + type, Toast.LENGTH_LONG).show();
}
}
}

我甚至尝试从通话记录中获取最后一个拨出电话的详细信息，但我收到所有电话，我只需要拨打最后一个电话。
这是代码 -
private String getCallDetails() {
StringBuffer sb = new StringBuffer();
Cursor managedCursor = MainActivity.managedCursor;
int number = managedCursor.getColumnIndex( CallLog.Calls.NUMBER );
int type = managedCursor.getColumnIndex( CallLog.Calls.TYPE );
int date = managedCursor.getColumnIndex( CallLog.Calls.DATE);
int duration = managedCursor.getColumnIndex( CallLog.Calls.DURATION);
sb.append( "Call Details :");
while ( managedCursor.moveToNext() ) {
String phNumber = managedCursor.getString( number );
String callType = managedCursor.getString( type );
String callDate = managedCursor.getString( date );
Date callDayTime = new Date(Long.valueOf(callDate));
String callDuration = managedCursor.getString( duration );
String dir = null;
int dircode = Integer.parseInt( callType );
switch( dircode ) {
case CallLog.Calls.OUTGOING_TYPE:
dir = "OUTGOING";
break;
case CallLog.Calls.INCOMING_TYPE:
dir = "INCOMING";
break;
case CallLog.Calls.MISSED_TYPE:
dir = "MISSED";
break;
}
sb.append( "\nPhone Number:--- "+phNumber +" \nCall Type:--- "+dir+" \nCall Date:--- "+callDayTime+" \nCall duration in sec :--- "+callDuration );
sb.append("\n----------------------------------");
}
managedCursor.close();
return sb.toString();
}
