Parsing a String representation of Double with comma decimal separator in Android cause NumberFormatException

I've used the same code parsing a String representation of Double with comma decimal separator (e.g. "0,3") on different versions of Android (2.3 and 4.*). It is strange, but in Android 2.3 the code was executed without any Exception, but in Android 4.* I've got NumberFormatException with the message: Invalid Double: 0,3

I've fixed it by replacement of comma for a dot separator in String object of my Double:

DecimalFormat newFormat = new DecimalFormat("#.#");

double result = 0;
   try {
       String doubleString = newFormat.format(constancyPercentage);
        result = Double.parseDouble(doubleString.replace(",", "."));//0,3 -> 0.3
} catch (NumberFormatException e) {
//TODO show nothing
}

Why maven doesn't downloads source and javadoc files

When you can not see any source code in your IDE such as Eclipse this most probably happen because your Maven (if you do use Maven) does not downloaded source jar file (e.g. filename-source.jar).

Maven does not downloads a source and javadoc jar files by default.

This option should be added to its settings file in ~/.m2/settings.xml file like this:

<profiles>
<profile>
    <id>downloadSources</id>
    <properties>
        <downloadSources>true</downloadSources>
        <downloadJavadocs>true</downloadJavadocs>           
    </properties>
</profile>
</profiles>

<activeProfiles>
  <activeProfile>downloadSources</activeProfile>
</activeProfiles>
