问题 I am using sms broadcast receiver in my application. When i send first sms it popups one message as sms sent. when i sent second request the popup message get doubled. In third time it tripled and so on. I am using following code for sending and receiving the broadcast. private void sendRequest() { String SENT = "SMS_SENT"; String DELIVERED = "SMS_DELIVERED"; PendingIntent sentPI = PendingIntent.getBroadcast(this, 0, new Intent(SENT), 0); PendingIntent deliveredPI = PendingIntent.getBroadcast

问题 I've got an activity which uses an AlarmManager to call a BroadcastReceiver at a particular point in time. This all works fine, except when I try to add some extra strings to the intent when calling the BroadcastReceiver, they always come up as null on the other end. Activity code: Intent intent = new Intent(this, ScheduleReceiver.class); intent.putExtra("testString", "I'm a string"); PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 999, intent, 0); AlarmManager alarmManager =

问题 Is it possible that a local (i.e. managed with LocalBroadcastManager) BroadcastReceiver leaks when the app is killed by the system? The specific use case for which I need it is that I would like to register/unregister the BroadcastReceiver in an Activity's onCreate/onDestroy (I need the receiver to be active when the activity is not visible), but I wouldn't like to risk causing a memory leak by doing this. As I understand, if a single activity is destroyed by the system, onDestroy runs and

问题 I have to use the getContentResolver method in a class that extends BroadcastReceiver and I found that getContentResolver can be used only in a class that extends Activity. I try to do a static method in a class that extends activity but i can't use getContentResolver in a static method. I also tried with a non-static method but when i run the appliaction I get an error. How can I do? Thanks! 回答1: In your onReceive(Context, Intent) you receive a Context object which has a getContentResolver()

问题 I'm using the GCM example from android developers and couldn't understand the purpose of the setResultCode(Activity.Result_OK). which component receiving this message? who is calling it and receiving it? here is the example public class GcmBroadcastReceiver extends WakefulBroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { ComponentName comp = new ComponentName(context.getPackageName(),GcmIntentService.class.getName()); startWakefulService(context, (intent

问题 I have an Activity class, in which I have a static flag, let's say public static volatile flag = false; Then in the class, I start a thread, which checks the flag and do different things. I also have a broadcastreceiver, which sets the flag to true or false. I though volatile will force the flag to the most recent value. But I can see my broadcastreceiver sets the static flag to true, but my thread is still getting it as false. Am I missing something basic here? Any help would be appreciated!

问题 I have an app that allows users to forward SMS messages as they are received. Back in the day, I had the android:priority in my intent-filter for android.provider.Telephony.SMS_RECEIVED set to barely above Android's default messaging app. I did so, so that the user can forward the messages without having to clear them in the messaging app. However, a few months later, Go SMS Pro released an update of their app with a android:priority value extremely high, so users with that app installed

问题 I want my app to detect if when the state of external storage changes. At first defined a BroadcastReceiver in my AndroidManifest.
