【Android】java.lang.RuntimeException: java.lang.Throwable: A WebView method was called on thread 'JavaBridge'.

一、问题

Java调用JS事件出现

java.lang.RuntimeException: java.lang.Throwable: A WebView method was called on thread 'JavaBridge'. All WebView methods must be called on the same thread. (Expected Looper Looper (main, tid 1) {3474c308} called on Looper (JavaBridge, tid 514) {2886ca4f}, FYI main Looper is Looper (main, tid 1) {3474c308})
