我在一个程序上向你们寻求帮助,看来它会奏效。如果我能让线程/异步任务工作。我已经尝试过线程,但我没有让它工作。我尝试进行线程处理的原因是因为我的程序在加载时崩溃了,基本上它的假设是在有人打电话时发送电子邮件,因为我总是把手机放错地方或保持静音,而我我不知道。
服务-
public class Callservice extends Service {
PhoneStateListener listener;
TelephonyManager tm;
@Override
public void onCreate()
{
Toast.makeText(getApplicationContext(), "Service has started", Toast.LENGTH_LONG).show();
listener = new MyphoneStateListener();
tm = (TelephonyManager)getSystemService(TELEPHONY_SERVICE);
tm.listen(listener, PhoneStateListener.LISTEN_CALL_STATE);
}
public class MyphoneStateListener extends PhoneStateListener
{
public void onCallStateChanged(int state, String incomingNumber)
{
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
break;
case TelephonyManager.CALL_STATE_RINGING:
sendemail();
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
default:
break;
}
super.onCallStateChanged(state, incomingNumber);
}
}
private void sendemail()
{
Intent i = new Intent(Intent.ACTION_SEND);
i.setType("message/rfc822");
i.putExtra(Intent.EXTRA_EMAIL , new String[]{"random@gmail.com"});
i.putExtra(Intent.EXTRA_SUBJECT , "phone is ringing");
i.putExtra(Intent.EXTRA_TEXT , "email successfully sent");
startActivity(Intent.createChooser(i, "send mail..."));
Toast.makeText(getApplicationContext(), "Email has been sent", Toast.LENGTH_LONG).show();
try
{
startActivity(Intent.createChooser(i, "Send Email..."));
}
catch(android.content.ActivityNotFoundException ex)
{

}
@Override
public IBinder onBind(Intent arg0) {

活动-
public class MainActivity extends Activity {
Callservice callservice = new Callservice();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
callservice.onCreate();
}
@Override
