问题描述
我想发送短信AMD邮件一起....与发送邮件钻时,我发短信没有问题,我收到此异常:结束渗漏IntentReceiver是否缺少调用unregisterReceiver(?)。你们只要告诉我在这里需要更改注销reciever?
这是我的code短信方式:
公共类端延伸活动{
按钮btnSendSMS;
的EditText txtPhoneNo;
的EditText txtMessage;
公众的EditText详细信息;
公共字符串的用户;
/ **第一次创建活动时调用。 * /
@覆盖
公共无效的onCreate(包savedInstanceState)
{
super.onCreate(savedInstanceState);
的setContentView(R.layout.end);
详情=(EditText上)findViewById(R.id.details);
btnSendSMS =(按钮)findViewById(R.id.btnSend);
叠B = this.getIntent()getExtras()。
最后弦乐电子邮件= b.getString(keym);
最后弦乐PNO = b.getString(钥匙);
btnSendSMS.setOnClickListener(新View.OnClickListener(){
公共无效的onClick(视图v){
。字符串细节= Details.getText()的toString();
邮件M =新邮件([email protected],sdfsa);
的String [] toArr = {电子邮件};
m.setTo(toArr);
m.setFrom([email protected]);
m.setSubject(紧急情况);
m.setBody(详细);
尝试 {
// m.addAttachment(/ SD卡/ filelocation);
如果(m.send()){
Toast.makeText(End.this,邮件发送成功,Toast.LENGTH_LONG).show();
} 其他 {
Toast.makeText(End.this,电子邮件未发送,Toast.LENGTH_LONG).show();
}
}赶上(例外五){
//Toast.makeText(MailApp.this,有一个问题,发送电子邮件。Toast.LENGTH_LONG).show();
Log.e(MailApp,无法发送电子邮件,E);
}
sendSMS(PNO,细节);
完();
意向意图=新的意图(End.this,Service.class);
startActivity(意向);
}
}
);
}
私人无效sendSMS(字符串phoneNumber的,字符串消息)
{
字符串SENT =SMS_SENT;
字符串DELIVERED =SMS_DELIVERED;
PendingIntent sentPI = PendingIntent.getBroadcast(此,0,
新的意图(SENT),0);
PendingIntent deliveredPI = PendingIntent.getBroadcast(此,0,
新的意图(交付),0);
// ---当短信已发送---
registerReceiver(新BroadcastReceiver的()
{
上下文语境;
@覆盖
公共无效的onReceive(背景为arg0,意图ARG1){
开关(的getResult code())
{
案例Activity.RESULT_OK:
Toast.makeText(getBaseContext(),短信发送
Toast.LENGTH_SHORT).show();
打破;
案例SmsManager.RESULT_ERROR_GENERIC_FAILURE:
Toast.makeText(getBaseContext(),一般故障,
Toast.LENGTH_SHORT).show();

案例SmsManager.RESULT_ERROR_RADIO_OFF:

Toast.LENGTH_SHORT).show();
打破;
}
}
},新的IntentFilter(发送));
// ---当SMS已交付---
registerReceiver(新BroadcastReceiver的(){
上下文语境;
@覆盖
公共无效的onReceive(背景为arg0,意图ARG1)
{
开关(的getResult code())
{
案例Activity.RESULT_OK:
Toast.makeText(getBaseContext(),SMS递送,
Toast.LENGTH_SHORT).show();
打破;
案例Activity.RESULT_CANCELED:
Toast.makeText(getBaseContext(),短信未交付,
Toast.LENGTH_SHORT).show();
打破;
}
}
},新的IntentFilter(交付));
SmsManager的短信= SmsManager.getDefault();
sms.sendTextMessage(phoneNumber的,空,消息,sentPI,deliveredPI);
}
}
解决方案
像这样创建一个自定义的接收器
类deliverReceiver扩展的BroadcastReceiver {
@覆盖
公共无效的onReceive(上下文的背景下,意图ARG1){
开关(的getResult code())
{
案例Activity.RESULT_OK:
Toast.makeText(getBaseContext(),SMS递送,
Toast.LENGTH_SHORT).show();
打破;
案例Activity.RESULT_CANCELED:
Toast.makeText(getBaseContext(),短信未交付,
Toast.LENGTH_SHORT).show();
打破;
}
}
}
和这样的发送reciever ..
类sentReceiver扩展的BroadcastReceiver {
@覆盖
公共无效的onReceive(上下文的背景下,意图ARG1){
开关(的getResult code())
{
案例Activity.RESULT_OK:
Toast.makeText(getBaseContext(),短信发送
Toast.LENGTH_SHORT).show();
打破;
案例SmsManager.RESULT_ERROR_GENERIC_FAILURE:
Toast.makeText(getBaseContext(),一般故障,
Toast.LENGTH_SHORT).show();
打破;
案例SmsManager.RESULT_ERROR_NO_SERVICE:
Toast.makeText(getBaseContext(),无服务,
Toast.LENGTH_SHORT).show();
打破;
案例SmsManager.RESULT_ERROR_NULL_PDU:
Toast.makeText(getBaseContext(),空的PDU,
Toast.LENGTH_SHORT).show();
打破;
案例SmsManager.RESULT_ERROR_RADIO_OFF:
Toast.makeText(getBaseContext(),无线电关
Toast.LENGTH_SHORT).show();
打破;
}
}
现在在sendSMS后,该方法
PendingIntent deliveredPI = PendingIntent.getBroadcast(此,0,
新的意图(交付),0);
把
registerReceiver(sentReceiver,发送);
registerReceiver(deliverReceiver,送到);
现在覆盖的onPause和取消像这样的接收器。
unregisterReceiver(sentReceiver);
unregisterReceiver(deliverReceiver);
I am trying to send sms amd mail together....no issues with sending mail bur when i send sms i receive this Exception: End has leaked IntentReceiver Are you missing a call to unregisterReceiver() ?. guys just tell me changes required here to unregister reciever ?
here is my code for sms method:
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);
}
}
解决方案
Create a custom receiver like this
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;
}
}
}
and a sent reciever like this..
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;
}
}
now in sendSMS method after this
PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0,
new Intent(DELIVERED), 0);
put
registerReceiver(sentReceiver,SENT);
registerReceiver(deliverReceiver,DELIVERED);
Now override onpause and unregister for the receivers like this..
unregisterReceiver(sentReceiver);
unregisterReceiver(deliverReceiver);
