android-pendingintent

问题 Here are my code : Android Manifest <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="pounya.id.location3"> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:roundIcon="@mipmap/ic_launcher_round" android:supportsRtl="true" android:theme="@style/AppTheme"> <meta-data android:name="com

问题 The documentation for AlarmManager seems to imply (but does not outright explicitly require) that the PendingIntent you pass in to any of the set() methods should be of the type BroadcastReceiver, but I tested passing in other component types (like an IntentService) and it seemed to work fine. Is it safe to use non-BroadcastReceiver Intents with AlarmManager? 回答1: Yes, and it has always worked, but I suspect not in the way that you're thinking. You can use any PendingIntent with an alarm;

问题 I have scheduled a PendingIntent with AlarmManager . When the AlarmManager delivers the Intent , I am able to getExtras() all the data that I originally sent. However, sometimes I get additional data that I want to pass with the Intent , before the AlarmManager fires. My thought was, I would just get the Intent like I was going to cancel it, but then after cancelling it, update the extras and reschedule it with the AlarmManager , like this: Intent i=new Intent(this, MyReceiver.class); Bundle

问题 In my app, I set an alarm AlarmManager alarmMgr = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE); ... PendingIntent pendingIntent = PendingIntent.getBroadcast(context, id, intent, PendingIntent.FLAG_UPDATE_CURRENT); ... alarmMgr.set(AlarmManager.RTC_WAKEUP, time.getTimeInMillis(), pendingIntent); It works fine unless I turn off and turn on the phone. To be more specific, let's say at 10:20, I set an alarm to 10:22 and I turn off and turn on the phone at 10:21, alarm won't work.

问题 I am interested in using pending intents with local broadcasts. To make myself clear, I am using the following for registering receivers and sending broadcast: android.support.v4.content.LocalBroadcastManager . I have a local broadcast receiver in a service which works. I am trying to send local broadcasts from a custom notification layout which includes click-able items. The local broadcast receiver - just receives simple action intents. I was trying something like this to no avail: Intent

问题 you can subscribe to requestLocationUpdates via two ways one by specifing a PendingIntent the other is by using a LocationListener When is advised the one and when the other? 回答1: If the component needing location updates only needs updates when the component is around -- say, an activity -- I'd use the LocationListener approach. If the component needing location updates specifically will not be around -- say, an IntentService -- I'd use the PendingIntent . You can't use the LocationListener

问题 I'm creating a PDF file on my app and writing it to the external storage, "Download" directory. Now, when I open it through my app with an intent action.VIEW using FileProvider uri, Google PDF Viewer displays a blank screen, Adobe Acrobat cannot even open the file. Here's my code to write the file and then trying to show it. Note that I'm sending a local notification and trying to open the file through the notification. try { File mypath=new File( Environment.getExternalStoragePublicDirectory

问题 I currently have a notification in my Android application that has a PendingIntent so that when it is clicked an activity is opened. I currently keep a counter for the notification, similar to the native missed calls notification. I can reset this counter to 0 when the notification is clicked. I also want to reset the counter to 0 when the user selects the "Clear all notifications" button. I have done a search and seen the way to do this is to use the DeleteIntent. But I cant figure out how
