broadcastreceiver

问题 SO currently i have an AsyncTask class that runs and POST's data to my server when I click a button(which works great). What im trying to do now is handle what happens when the user is not connected to the internet. so i have set up these classes to notify the app when internet has connected so that the data can be sent automatically to the server. AsyncTask class(inner class) private class HttpAsyncTask extends AsyncTask<String, Void, String> { ProgressDialog dialog = new ProgressDialog

问题 I would like to know if there is an equivalent android.content.BroadcastReceiver in Swift. I would need the same handler like onReceive(Context context, Intent intent) It is possible ? Thank you Ysee 回答1: In Swift in order to achieve the same effect you would use the NSNotificationCenter .

问题 I want to receive notification when Mobile network connection is lost or received. Through following code, I can receive notification for Wi-Fi (Data) connection but not for Mobile (Voice) connection. Manifest : <uses-permission android:name="android.permission.ACCESS_NETWORK_ST ATE"/> <application android:icon="@drawable/icon" android:label="@string/app_name"> <receiver android:name=".notifier"> <intent-filter> <action android:name="android.net.conn.CONNECTIVITY_CHANGE " /> </intent-filter>

问题 So I have two different apps made, one sends a broadcast and another receives it and displays a toast. However, when I close the receiver app the broadcast is no longer received by the second app even though I defined the receiver in the manifest file. The broadcast sender in the MainActivity of app1. public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main);

问题 I am trying to intercept SMS messages delivered to my device. I wrote an app to do that a year or so ago, and I find it is no longer catching messages (even though code is unchanged). I don't believe it is permission-related. I tried compiling under SDK 23 (requiring runtime permissions) and SDK 22 (no runtime permissions). (In the case of 23, I verified that permission RECEIVE_SMS is successfully granted). Most questions/answers about this issue are quite old. IMHO The answers didn't seem

问题 When my application is launched, it performs an API call and then schedules notifications based on the results. This amounts to around ~10 notifications being scheduled. There seems to be an issue with the timestamp displayed on the actual notification being incorrect. Since I am creating these notifications and then scheduling an alarm with an AlarmManager , the default time present on the notification will be the time at which the notification is created ( System.currentTimeMillis() ). I've

问题 I already have a few receivers running, including one for reboot and entering flight mode. However I'm not always getting the Intent in time for me to do what I need to do, send a quick message to an external server. Even setting the intent filter to priority 1000 doesn't guarantee that I get to transmit before it is too late, though it does help. As stated, it is not that I do not receive my broadcasts, I just get them too late, after the network is already down. Any pointers to where I may
