As far as I know, apps can't get intents for their own uninstallation: ACTION_PACKAGE_FULLY_REMOVED ACTION_PACKAGE_REMOVED But how does Dolphin Browser manage to receive a "removed" event and start a browser as in the attached image ?

AlarmManager does not work when app is force closed

由 爱⌒轻易说出口 提交于 2019-11-26 21:19:37
问题 Documentation for AlarmManager startes that Note: The Alarm Manager is intended for cases where you want to have your application code run at a specific time, even if your application is not currently running. For normal timing operations (ticks, timeouts, etc) it is easier and much more efficient to use Handler. However, once my application is closed (force close from task manager) my alarm does not work and the OnReceive method is never called inside the broadcast receiver. I am targeting 4

How to get sms sent confirmation for each contact/person in android?

由 这一生的挚爱 提交于 2019-11-26 17:57:57
I want to send sms to multiple people and verify whether sms sent or not. I checked multiple links (mentioned here) and got the idea of using PendingIntent and broadCast Receiver for confirmation. Practical way to find out if SMS has been sent Sending text messages programmatically in android http://mobiforge.com/design-development/sms-messaging-android But the key problem is that, I have different 50 contacts number in an arrayList and their different msgs in another arrayList . I use this code : for (Condition) { sms = SmsManager.getDefault(); try { . . . sms.sendTextMessage(phoneNumbers[i],

由 ε祈祈猫儿з 提交于 2019-11-26 14:40:06
问题 EDIT: This question was created as part of one of my first Android projects when I was just starting out with Android application development. I'm keeping this for historical reasons, but you should consider using EventBus or RxJava instead. This is a gigantic mess. Please DO NOT CONSIDER using this. Thank you. In fact, if you want something cool that solves the problem of using a single activity with multiple "fragments", then use flowless with custom viewgroups. I have implemented a way to
