这个errpr是什么？
支持的源版本＆＃39; RELEASE_7＆＃39;来自注释处理器＆＃39; android.arch.lifecycle.LifecycleProcessor＆＃39;少于-source＆＃39; 1.8＆＃39;
我们添加了
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
在gradle中没有用;
Error:Error converting bytecode to dex:
Cause: Dex cannot parse version 52 byte code.
This is caused by library dependencies that have been compiled using Java 8 or above.
If you are using the 'java' gradle plugin in a library submodule add
targetCompatibility = '1.7'
sourceCompatibility = '1.7'
to that submodule's build.gradle file.
