Permission Denial: startForeground requires android.permission.FOREGROUND_SERVICE

by

Lately we have suddenly been seeing a few of the following stack traces. Why could that be? This is from when the app tries to move an audio commentary service into the foreground with a media notification and everything. java.lang.SecurityException: Permission Denial: startForeground from pid=1824, uid=10479 requires android.permission.FOREGROUND_SERVICE at android.os.Parcel.createException(Parcel.java:1942) at android.os.Parcel.readException(Parcel.java:1910) at android.os.Parcel.readException(Parcel.java:1860) at … Read more

Android Fatal signal 11 (SIGSEGV) at 0x636f7d89 (code=1). How can it be tracked down?

by

I’ve been reading the other posts on tracking down the reasons for getting a SIGSEGV in an Android app. I plan to scour my app for possible NullPointers related to Canvas use, but my SIGSEGV barfs up a different memory address each time. Plus I’ve seen code=1 and code=2. If the memory address was 0x00000000, … Read more

Trying to start a service on boot on Android

by

I’ve been trying to start a service when a device boots up on android, but I cannot get it to work. I’ve looked at a number of links online but none of the code works. Am I forgetting something? AndroidManifest.xml <receiver android:name=”.StartServiceAtBootReceiver” android:enabled=”true” android:exported=”false” android:label=”StartServiceAtBootReceiver” > <intent-filter> <action android:name=”android.intent.action._BOOT_COMPLETED” /> </intent-filter> </receiver> <service android:name=”com.test.RunService” android:enabled=”true” … Read more

by

I couldn’t find a satisfying answer to this, so here we go: what’s the deal with Activity/Service.getApplication() and Context.getApplicationContext()? In our application, both return the same object. In an ActivityTestCase however, mocking the application will make getApplication() come back with the mock, but getApplicationContext will still return a different context instance (one injected by Android). … Read more

Example: Communication between Activity and Service using Messaging

by

I couldn’t find any examples of how to send messages between an activity and a service, and I have spent far too many hours figuring this out. Here is an example project for others to reference. This example allows you to start or stop a service directly, and separately bind/unbind from the service. When the … Read more

Service vs IntentService in the Android platform

by

I am seeking an example of something that can be done with an IntentService that cannot be done with a Service (and vice-versa)? I also believe that an IntentService runs in a different thread and a Service does not. So, as far as I can see, starting a service within its own thread is like … Read more
