I know that there are many questions about the API level and version of Android, but this question is different, so please do not mark it as a duplicate.
I am wondering how Java version 1.6, 1.7, 1.8 ... relates to these two. The source of my confusion I am trying to use Pattern.compilea Pattern.UNICODE_CHARACTER_CLASSflag method as shown below.
Pattern pattern = Pattern.compile("\\b" + keywordToCheck + "\\b", Pattern.UNICODE_CHARACTER_CLASS);
The documents to Pattern.UNICODE_CHARACTER_CLASSsay that he says that: 1.7: I guess it's available in a Java version 1.7 or higher. I try to use this line of code in an Android project, but every time I run it on my device, I get:
java.lang.IllegalArgumentException: Unsupported flags: 256
Below are the relevant parts of my build.gradle file.
defaultConfig {
minSdkVersion 19
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
