这似乎适合我现在要做的事情。任何机会,你可以告诉我完整的来源?目前,我有它的工作为我的代码,但我想看看你是如何得到GPS联合ORDS和启动异步
ProgressDialog progressDialog;
double longitude, latitude;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_confirm_screen);

Boolean locationCheck = sp.getBoolean("LOCATION", false);
if(locationCheck){
}
else
{
sendEmail();
playSound();
}
}

});
LocationManager mlocManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
LocationListener mlocListener = new MyLocationListener();
mlocManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, mlocListener);
progressDialog.setCancelable(true);
progressDialog.setMessage("Getting GPS Location...");
progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
progressDialog.setProgress(1);
progressDialog.show();
}

super.onProgressUpdate(values);
// Things to be done while execution of long running operation is in progress. For example updating ProgessDialog
}

谢谢您的回答其实我解决了这个问题。现在它的一个不同'SmsManager smsManager = SmsManager.getDefault(); \t \t \t \t \t \t \t \t \t \t smsManager.sendTextMessage(sms_phonenumber,NULL,消息,sentPI,NULL); '它说空指针异常..你有什么想法...谢谢 – GoCrazy
你应该用你最近的错误创建一个新的问题,因为它很难解决我们看不到的问题。 – Guardanis
@cruceo感谢您的评论..我已经解决了这个问题.. – GoCrazy
