我编写了一个简单的服务，它有一个广播接收器，它监听传入的短信并将有关消息的信息写入数据库。问题是每次收到消息时，服务的 RAM 使用量都会增加 1-2 MB。
// Init
smsRecFilter.setPriority(999);
smsRecFilter.addAction("android.provider.Telephony.SMS_RECEIVED");
registerReceiver(smsReceiver, smsRecFilter);
// Implementation
private class SMSreceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Bundle extras = intent.getExtras();
if (extras != null) {
SmsMessage smsMsg;
Object[] smsPdus = (Object[])extras.get("pdus");
if (smsPdus != null) {
InfoHolder holder = new InfoHolder();
if (holder != null) {
holder.Type = InfoTypes.SMS_REC;
for (int i = 0; i < smsPdus.length; i++) {
smsMsg = SmsMessage.createFromPdu((byte[])smsPdus[i]);
if (smsMsg != null) {
if (i == 0) {
holder.Number = smsMsg.getOriginatingAddress();
holder.DateTime = MillisToDate(smsMsg.getTimestampMillis());
}
holder.MsgBody += smsMsg.getMessageBody().toString();
}
}
m_db.Insert(holder);
}
}
}
}
}
更新
插入方法：
my Insert() function:
private boolean Insert(InfoHolder holder)
{
try {
ContentValues values = new ContentValues();
if (values != null) {
values.put( DBase.COLUMN_TYPE, holder.Type);
values.put( DBase.COLUMN_NUMBER, holder.Number);
values.put( DBase.COLUMN_MSGBODY, holder.MsgBody);
values.put( DBase.COLUMN_CALL_DUR, holder.CallDuration);
values.put( DBase.COLUMN_DATETIME, holder.DateTime);
mDB.insert(DB_TABLE_NAME, null, values);
values.clear();
}
}
catch( Exception e ) {return false;}
return true;
}
