L'activité a divulgué IntentReceiver
J'essaie d'envoyer des messages sms AMD ensemble. L'envoi de courrier électronique ne pose aucun problème, mais lorsque j'envoie des SMS, je reçois cette exception:
End has leaked IntentReceiver
Are you missing a call to unregisterReceiver()?
Voici mon code pour la méthode sms:
public class End extends Activity {
Button btnSendSMS;
EditText txtPhoneNo;
EditText txtMessage;
public EditText Details;
public String user;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.end);
Details = (EditText)findViewById(R.id.details);
btnSendSMS = (Button) findViewById(R.id.btnSend);
Bundle b=this.getIntent().getExtras();
final String email=b.getString("keym");
final String pno=b.getString("keys");
btnSendSMS.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
String detail=Details.getText().toString();
Mail m = new Mail("[email protected]", "sdfsa");
String[] toArr = {email};
m.setTo(toArr);
m.setFrom("[email protected]");
m.setSubject("EMERGENCY");
m.setBody(detail);
try {
// m.addAttachment("/sdcard/filelocation");
if(m.send()) {
Toast.makeText(End.this, "Email was sent successfully.", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(End.this, "Email was not sent.", Toast.LENGTH_LONG).show();
}
} catch(Exception e) {
//Toast.makeText(MailApp.this, "There was a problem sending the email.", Toast.LENGTH_LONG).show();
Log.e("MailApp", "Could not send email", e);
}
sendSMS(pno, detail);
finish();
Intent intent = new Intent(End.this,Service.class);
startActivity(intent);
}
}
);
}
private void sendSMS(String phoneNumber, String message)
{
String SENT = "SMS_SENT";
String DELIVERED = "SMS_DELIVERED";
PendingIntent sentPI = PendingIntent.getBroadcast(this, 0,
new Intent(SENT), 0);
PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0,
new Intent(DELIVERED), 0);
//---when the SMS has been sent---
registerReceiver(new BroadcastReceiver()
{
Context context;
@Override
public void onReceive(Context arg0, Intent arg1) {
switch (getResultCode())
{
case Activity.RESULT_OK:
Toast.makeText(getBaseContext(), "SMS sent",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
Toast.makeText(getBaseContext(), "Generic failure",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_NO_SERVICE:
Toast.makeText(getBaseContext(), "No service",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_NULL_PDU:
Toast.makeText(getBaseContext(), "Null PDU",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_RADIO_OFF:
Toast.makeText(getBaseContext(), "Radio off",
Toast.LENGTH_SHORT).show();
break;
}
}
}, new IntentFilter(SENT));
//---when the SMS has been delivered---
registerReceiver(new BroadcastReceiver(){
Context context;
@Override
public void onReceive(Context arg0, Intent arg1)
{
switch (getResultCode())
{
case Activity.RESULT_OK:
Toast.makeText(getBaseContext(), "SMS delivered",
Toast.LENGTH_SHORT).show();
break;
case Activity.RESULT_CANCELED:
Toast.makeText(getBaseContext(), "SMS not delivered",
Toast.LENGTH_SHORT).show();
break;
}
}
}, new IntentFilter(DELIVERED));
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI);
}
}
Créez un récepteur personnalisé comme celui-ci
class deliverReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent arg1) {
switch (getResultCode())
{
case Activity.RESULT_OK:
Toast.makeText(getBaseContext(), "SMS delivered",
Toast.LENGTH_SHORT).show();
break;
case Activity.RESULT_CANCELED:
Toast.makeText(getBaseContext(), "SMS not delivered",
Toast.LENGTH_SHORT).show();
break;
}
}
}
et un récepteur envoyé comme ça ..
class sentReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent arg1) {
switch (getResultCode())
{
case Activity.RESULT_OK:
Toast.makeText(getBaseContext(), "SMS sent",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
Toast.makeText(getBaseContext(), "Generic failure",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_NO_SERVICE:
Toast.makeText(getBaseContext(), "No service",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_NULL_PDU:
Toast.makeText(getBaseContext(), "Null PDU",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_RADIO_OFF:
Toast.makeText(getBaseContext(), "Radio off",
Toast.LENGTH_SHORT).show();
break;
}
}
maintenant dans la méthode sendSMS après cette
PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0,
new Intent(DELIVERED), 0);
mettre
registerReceiver(sentReceiver,SENT);
registerReceiver(deliverReceiver,DELIVERED);
Maintenant, annulez la pause et annulez l'enregistrement pour les récepteurs comme celui-ci.
unregisterReceiver(sentReceiver);
unregisterReceiver(deliverReceiver);
Vous devez désenregistrer les récepteurs dans onPause() et les enregistrer dans onResume(). De cette façon, lorsque Android détruit et recrée l'activité pour le changement de configuration, ou pour une raison quelconque, vous aurez toujours des récepteurs configurés.
Vous avez enregistré deux récepteurs de diffusion dans votre activité. Dans Détruisez votre activité, désenregistrez les deux récepteurs. Reportez-vous http://developer.Android.com/reference/Android/content/ContextWrapper.html#unregisterReceiver (Android.content.BroadcastReceiver ).
