    - by kefs
    I'm looking to create AVDs to test my apps on, and i'm trying to figure out the correct settings for a square screen such as the new Motorola Flip Out. I don't see a wikipedia article for it, or many specs... On a related note, what about tablets? Actually.. Why aren't there a set of AVD instances with params from popular devices.. or at least a site that lists them for each of the 60+ devices. Thanks in advance :)

  • Get address using Geocoder in android

    - by user264953
    Hi, I tried to get the address of a particular location by giving static geocordinates. I was not able to fetch the address. Can someone please help. I just need to check whether this function works for me. Here is my snippet. Geocoder geocoder = new Geocoder(AddressSimulator.this, Locale.getDefault()); List<Address> addresses = geocoder.getFromLocation(1.352566007, 103.78921587, 1); System.out.println("Addresses size"+addresses.size()); Address size is obtained as zero. I tried with few other geocordinates also, but address size is always returned as 0. Experts, kindly help me resolve this. Looking forward for your valuable help/suggestions, Best Regards, Rony

  • How to receive sms from a special phone number?

    - by Pariya
    I wrote a send and receive sms in android successfully. I want my program to be able to receive sms from a special number("+9856874236"). But, if the SMS is from any other number, it should go to the phone's message inbox and not to my application. import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.os.Bundle; import android.telephony.SmsMessage; import android.util.Log; public class SmsReceiver extends BroadcastReceiver { public String str = ""; @Override public void onReceive(Context context, Intent intent) { Bundle bundle = intent.getExtras(); Object messages[] = (Object[]) bundle.get("pdus"); SmsMessage[] msgs = null; if (bundle != null) { Object[] pdus = (Object[]) bundle.get("pdus"); SmsMessage smsMessage[] = new SmsMessage[messages.length]; String msg_from=""; for (int n = 0; n < messages.length; n++) { smsMessage[n] = SmsMessage.createFromPdu((byte[]) messages[n]); msg_from += msgs[n].getOriginatingAddress(); } String receivedMessage = smsMessage[0].getMessageBody().toString().toUpperCase(); if(msg_from .equals("+989124236870")) { for (int n = 0; n < messages.length; n++) { smsMessage[n] = SmsMessage.createFromPdu((byte[]) pdus[n]); str += "SMS from " + msgs[n].getOriginatingAddress(); str += " :"; //str += "sms az shomare makhsus"; str += msgs[n].getMessageBody().toString(); str += "\n"; abortBroadcast(); } Intent act = new Intent(context, MainActivity.class); act.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); act.putExtra("message", str); context.startActivity(act); } } } }

  • The application has stopped unexpectedly: How to Debug?

    - by Android Eve
    Please note, unlike many other questions having the subject title "application has stopped unexpectedly", I am not asking for troubleshooting a particular problem. Rather, I am asking for an outline of the best strategy for an Android/Eclipse/Java rookie to tackle this formidable task of digesting huge amounts of information in order to develop (and debug!) a simple Android application. In my case, I took the sample skeleton app from the SDK, modified it slightly and what did I get the moment I try to run it? The application (process.com.example.android.skeletonapp) has stopped unexpectedly. Please try again. OK, so I know that I have to look LogCat. It's full of timestamped lines staring at me... What do I do now? What do I need to look for? Is there a way to single-step the program, to find the statement that makes the app crash? (I thought Java programs never crash, but apparently I was mistaken) How do I place a breakpoint? Can you recommend an Android debug tutorial online, other than this one?

  • Error in Android's clearCheck() for RadioGroup?

    - by Manuel R. Ciosici
    I'm having an issue with RadioGroup's clearChecked(). I'm displaying a multiple choice question to the user and after the user selects an answer I check the answer, give him some feedback and then move to the next question. In the process of moving to the next question I clearCheck on the RadioGroup. Can anyone explain to me why the onCheckedChanged method is called 3 times? Once when the change actually occurs (with the user changes), once when I clearCheck(with -1 as the selected id) and once in between (with the user changes again)? As far as I could tell the second trigger is provoked by clearCheck. Code below: private void checkAnswer(RadioGroup group, int checkedId){ // this makes sure it doesn't blow up when the check is cleared // also we don't check the answer when there is no answer if (checkedId == -1) return; if (group.getCheckedRadioButtonId() == -1) return; // check if correct answer if (checkedId == validAnswerId){ score++; this.giveFeedBack(feedBackType.GOOD); } else { this.giveFeedBack(feedBackType.BAD); } // allow for user to see feedback and move to next question h.postDelayed(this, 800); } private void changeToQuestion(int questionNumber){ if (questionNumber >= this.questionSet.size()){ // means we are past the question set // we're going to the score activity this.goToScoreActivity(); return; } //clearing the check gr.clearCheck(); // give change the feedback back to question imgFeedback.setImageResource(R.drawable.question_mark); //OTHER CODE HERE } and the run method looks like this public void run() { questionNumber++; changeToQuestion(questionNumber); }

  • Placing the where condition

    - by user182944
    I came up with the below query: SELECT ROOMNO,BUILDINGNO FROM MRM_ROOM_DETAILS WHERE ROOMID IN ( SELECT distinct roomid FROM MRM_BOOKING_DETAILS WHERE (CHECKIN NOT BETWEEN '2012-04-13 09:50:00' AND '2012-04-13 10:20:00') AND (CHECKOUT NOT BETWEEN '2012-04-13 09:50:00' AND '2012-04-13 10:20:00')) AND CAPACITY > 15 AND PROJECTIONSTATUS = 'NO'; I need to place this query in the method SQLiteDatabase.query() and fetch the rows accordingly. I am not able to understand how to place this big where condition (which contains a sub-query as well) in place of the "String selection" i.e. 3rd parameter of the method. Shall i simple write the entire where part(including the sub-query) as a string in the 3rd parameter or else there is some other better way for doing the same? Please suggest me the best way to do the same. Regards,

  • Why would you use the ternary operator without assigning a value for the "true" condition?

    - by RickNotFred
    In the Android open-source qemu code I ran across this line of code: machine->max_cpus = machine->max_cpus ?: 1; /* Default to UP */ It this just a confusing way of saying: if (machine->max_cpus) { ; //do nothing } else { machine->max_cpus = 1; } If so, wouldn't it be clearer as: if (machine->max_cpus == 0) machine->max_cpus = 1; Interestingly, this compiles and works fine with gcc, but doesn't compile on http://www.comeaucomputing.com/tryitout/ .

  • make emacs in a terminal use dark colors and not light font-lock colors

    - by vy32
    I am using emacs on MacOS 10.6 with Terminal. I have a white background. It's very hard to read quoted C++ strings. They are coming up in pale green. Keywords are in turquoise. After searching through the source I cam across cpp.el and have determined that I am using the cpp-face-light-name-list instead of cpp-face-dark-name-list. Apparently this function is supposed to chose the correct list based on the background color: (defcustom cpp-face-default-list nil "Alist of faces you can choose from for cpp conditionals. Each element has the form (STRING . FACE), where STRING serves as a name (for `cpp-highlight-buffer' only) and FACE is either a face (a symbol) or a cons cell (background-color . COLOR)." :type '(repeat (cons string (choice face (cons (const background-color) string)))) :group 'cpp) But it doesn't seem to be working. What should I put in my .emacs file so that I get the cpp-face-dark-list instead of cpp-face-light-list? Thanks!
