Description
I have java 1.8 installed in my build path and use 7.0.2.GA SDK.
I need to build android module.
I cannot build for java 1.8 - java 1.7 does not support method references.
Api2.java:33: error: method references are not supported in -source 1.7
[ERROR] .flatMap(ApiResponse::handleError)
This was done on purpose. We currently only support Java 7 language features. We added Java 7 support as of Titanium 7.0.0. You can compile with JDK 8, but we purposely set up the Java compiler to build with Java 7, which is the
-source 1.7argument you see in the log. The reason we don't support the Java 8 language is because Google does not fully support Java 8 yet. See the link below. Some Java 8 features are supported on all Android OS versions, such as method references. But there are other Java 8 features that are only supported on Android 7.0 (aka: API Level 24) and higher... and this is the main problem that is best avoided. https://developer.android.com/studio/write/java8-support.html#supported_features Also, the impression is that Android's Java 8 support is not fully debugged yet either... https://developer.android.com/studio/write/java8-support.html#disable Java 7 has the best support on Android at the moment. Especially since it's supported on all Android OS versions. So, the plan is to stick to Java 7 until the Java 8 situation on Android improves.
