从BroadcastReceiver发送短信时崩溃
从BroadcastReceiver发送短信时崩溃
提问于 2011-08-11 07:34:08
我有一个BroadcastReceiver，当收到短信时，它会查询数据库，并从数据库结果中发出适当的短信。我遇到的问题是，当我到达它发送SMS的部分时，它总是崩溃
public class SMSReceiver extends BroadcastReceiver {
SQLiteDatabase db;
private static final String ACTION = "android.provider.Telephony.SMS_RECEIVED";
private static String messagefrom;
private static String messagebody;
final String dbTable = "Realtor_SMS_Table";
@Override
public void onReceive(Context context, Intent intent) {
if (intent != null && intent.getAction() != null
&& ACTION.compareToIgnoreCase(intent.getAction()) == 0) {
Object[] pduArray = (Object[]) intent.getExtras().get("pdus");
SmsMessage[] messages = new SmsMessage[pduArray.length];
for (int i = 0; i < pduArray.length; i++) {
messages[i] = SmsMessage.createFromPdu((byte[]) pduArray[i]);
messagefrom = messages[i].getOriginatingAddress();
messagebody = messages[i].getMessageBody();
Log.d("My SMSReceiver", "From: " + messagefrom);
Log.d("My SMSReceiver", "Msg: " + messagebody);
FilterMessage(dbTable, messagefrom, messagebody);
}
Log.d("My SMSReceiver", "SMSReceived");
}
}
public void FilterMessage(String dbTable, String messagefrom,
String messagebody) {
String myPath = "/data/data/com.RealtorSMS/databases/RealtorDB.db";
db = SQLiteDatabase.openDatabase(myPath, null,
SQLiteDatabase.OPEN_READONLY);
Cursor cursor = db.query(dbTable, new String[] { "_id", "Description",
"URL" }, "_id like " + "'%" + messagebody + "%'", null, null,
null, null);
Log.d("My SMSReceiver", "sql= " + cursor);
if (cursor != null) {
cursor.moveToFirst();
String messageAddress = null;
String messageDescription = null;
String messageURL = null;
while (cursor.isAfterLast() == false) {
messageAddress = cursor.getString(0);
messageDescription = cursor.getString(1);
messageURL = cursor.getString(2);
}
SmsManager sm = SmsManager.getDefault();
sm.sendTextMessage(messagefrom, null, messageAddress + " "
+ messageDescription, null, null);
sm.sendTextMessage(messagefrom, null, messageAddress + " "
+ messageURL, null, null);
}
}
}下面是logcat：

您可能需要将处理逻辑移动到单独的服务中:不是在onReceive方法中调用FilterMessage，而是调用startService并在单独的线程中执行处理。ANR是因为您的FilterMessage函数的某些部分花费的时间太长:我预计您的数据库打开/循环/关闭花费的时间太长。
