sms = new SmsMessage[pdus.length];
for (int i = 0; i < sms.length; i++) {
sms[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
if (i == 0) {
sender += sms[i].getOriginatingAddress();
str += ":"+sms[i].getMessageBody().toString();
if (sms[i].getMessageBody().equals("Ring")) {
AudioManager am = (AudioManager)context.getSystemService(Context.AUDIO_SERVICE);
int maxVolume = am.getStreamMaxVolume(AudioManager.STREAM_RING);
am.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
am.setStreamVolume(AudioManager.STREAM_RING, maxVolume,AudioManager.FLAG_SHOW_UI + AudioManager.FLAG_PLAY_SOUND);
}
}
}
Toast.makeText(context, str, Toast.LENGTH_SHORT).show();
Log.d("Receiving", str);
}
}
}
Further more caused in log is showing NULLPOINTEREXCEPTION(), but i didn't get there is no code that throws exception.
But it is working fine as well it shows unfortunate message whenever i receive message on other app also.

I tried to look for some examples online but none of them seems to work for me, Please point me where am getting things wrong.
I will appreciate your contribution, Thanks

I don't know what has gone wrong, but I'm having a difficult time with this one. The program is supposed to show a toast once a message is received. I have tried adding the priority in the manifest file, but it doesn't work.

use this code to receive the push...
public class MyCustomReceiver extends BroadcastReceiver {

Bundle extras = intent.getExtras();
String message = extras != null ? extras.getString("com.parse.Data")

gcmMessage.setType(0);
gcmMessage.setDateTime(time);
DatabaseUtil.insertMessage(context, gcmMessage);
}
}
catch (JSONException e) {
e.printStackTrace();
}
}
}
and here is the code to send push...
JSONObject obj;
try {
obj =new JSONObject();
obj.put("alert","oman expert ");
obj.put("action","Your Package name.UPDATE_STATUS");
data.put("from", ParseUser.getCurrentUser().getUsername());
obj.put("msg","hi");

ParsePush push = new ParsePush();
ParseQuery query = ParseInstallation.getQuery();
push.setQuery(query);
push.setData(obj);
push.sendInBackground();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
for any further query please let me know....
In the above code example, you have missed out few things,
Check your AndroidManifest.xml file, and add c2dm permissions,
permission android:name="your package.permission.C2D_MESSAGE" android:protectionLevel="signature"
uses-permission android:name="com.google.android.c2dm.permission.RECEIVE"
uses-permission android:name="your package.permission.C2D_MESSAGE"
While sending the data, set the action in your data,
JSONObject data = new JSONObject();
try {
data.put("action", "your package.GOT_MESSAGE");
data.put("ya", ya);
data.put("from", ParseUser.getCurrentUser().getUsername());
}catch (Exception e){
e.printStackTrace();
return;
}
ParsePush parsePush = new ParsePush();
parsePush.setData(data);
Hi I am working on BroadCastReciver. There are two way to define BroadCastReciver.First one is using Java code and Second one is define in AndroidManifest.xml using . In my code second one is don't work properly.please tell where am i goes wrong.
public class HotelReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
String dActionName = intent.getAction();
Log.i("My Rceiver ", intent.getAction());
if (dActionName.equals(Intent.ACTION_SCREEN_ON)) {
Toast.makeText(context, "SCREEN ON", Toast.LENGTH_SHORT).show();
} else if (dActionName.equals(Intent.ACTION_SCREEN_OFF)) {

I think your reciever should read
<receiver
android:name="HotelReceiver">
<intent-filter>
<action android:name="android.intent.action.SCREEN_ON"/>
</intent-filter>
</receiver>
no dot "."
Just use this code inside of onCreate() for your activity,
IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);
filter.addAction(Intent.ACTION_SCREEN_OFF);
HotelReceiver mReceiver = new HotelReceiver(this);
registerReceiver(mReceiver, filter);
