问题 I released a version of my app to the Google Play and woke up this morning with a number of unhappy customers. The latest version of the app integrates support for a Bluetooth Low Energy (BTLE) heart rate monitor. The app runs fine on Android 4.3 and 4.4 but crashes on 4.0, 4.1, and 4.2 with the following error.

问题 I have a multi module Android Maven project which consists of several projects and an Android library project (baselib) where I run non Android based JUnit tests. This works as long as I run the test by Maven. When I run the baselib JUnit tests by Eclipse with Run->As JUnit test, I don't get the current version. That means that changes in the JUnit test have no effect until I make a Maven build. I thought about adding the bin folder to the Eclipse build path, but I get an error message in

问题 For developing a JavaFX application I'm using a 4.3.1 snapshot of eclipse together with JDK 8 build b116. In my workspace projects the JRE library inclusion in the build path get resetted back to Java 1.4 all the time: Unfortunately, this can only be fixed temporary (until the next eclipse restart): In the build section of my pom files I have: <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.1</version> <configuration> <source>1.8<
