android-broadcastreceiver

问题 So I have followed this guideline to show a simple toast when SMS is received. While it works ok when app is running, when I go to settings and force-close the app, it stops working. I checked many answers here on StackOverflow for simmilar questions, but none actually answers whether (and how) it is possible to make a piece of code execute EVERY time SMS is received, without the app being set as the default SMS app on device (Android 4.4+). Is it? Consider that even service can be stopped,

问题 I am trying to send an intent from a non system app using the following function. public static void sendIntent() { if (null != _context) { Intent intent = new Intent("com.test.testApp.testIntent"); intent.setPackage(_context.getPackageName()); _context.sendBroadcast(intent); } } But I always see there is an error message from ActivityManager as below. The same intent broadcasting(app) works fine in andorid 6.0 but throws an error in android 7.1.1. I am required to change anything for android

问题 Hi I am using alarm Manager for specific time interval for 3 minutes and I started monitoring. It worked for sometimes and suddenly I noticed there is irregular time interval which is not correct! You can see in attached log where at "20-Jul-2016 12:22:03 pm" time varies! I connected the phone and turned off the screen and monitored! where for every 3 minutes, i hit the server and gets the response as 1. But at one time, it takes 5 minutes to hit the server! Why this strange issue happened?
