问题 In attempting to implement notifications in an android app, I am seeing that the notifications no longer work if a user closes the app from the Running App List (top swipe down and then horizontal swipe - not force quit which properly would shut down all future invocations as per google specs). Using the back button sometimes causes the same behaviour, though not always. My understanding from everything that I have researched is that only a force stop by the user should stop the Broadcast

问题 Simple question, Is it possible to send/receive intents in the same class through LocalBroadcastReceiver ? If yes can you show me an example? 回答1: Yes, LocalBroadcastReceiver works everywhere. Here's an example for an Activity : BroadcastReceiver localBroadcastReciever = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { Log.d("BroadcastReceiver", "Message received " + intent.getAction()); } }; @Override protected void onStart() { super.onStart();

问题 I am trying to learn Android app development and wrote a very simple app consisting of an activity that calls a service. The service broadcasts measured acceleration to the activity. The problem is that the service runs ok but it does not send data back to the activity. i.e, onReceive on my receiver is never called. Also, when the activity ends, there is an exception saying that my receiver has not been registered. Below is my code for the service, activity and manifest.xml. Any help would be

问题 I'm sending a Broadcast from a service and then receiving it back from inner BroadcastReceiver class. I have to show an AlertDialog based on some logic but while trying to do it, I'm getting this runtime error: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity. Here's MyBroadcastReceiver class: public class MyBroadcastReceiver extends BroadcastReceiver { public MyBroadcastReceiver(){ super(); } @Override public void onReceive(final

问题 I have a plugin for my app that is started with a BroadCast. I already managed to add a custom permission, so only apps with the permission can receive the broadcast. However, I have no idea how to achieve the more important part: How can I check, if the sender has a custom permission, so only my main app can send the broadcast? I know this is possible, but I don't know how to do it. Thanks! 回答1: Try using: Context ctx = ...; int result = ctx.checkCallingPermission("your.permission.goes.here"

问题 I don't want to use google cast code to connect devices from my app but needed to just check whether the phone is connected to any cast Device. Do we get any Receiver/listener for this check? Thanks! EDIT: I have tried to get Cast State as following as mentioned by Chris, Add following in Manifest <meta-data android:name="com.google.android.gms.cast.framework.OPTIONS_PROVIDER_CLASS_NAME" android:value=".CastOptionsProvider" /> Create CastOptionProvider Class public class CastOptionsProvider
