Android - A WebView method was called on thread 'JavaBridge _Android

【Android - A WebView method was called on thread ' JavaBridge】敢说敢作敢为，无怨无恨无悔。这篇文章主要讲述Android - A WebView method was called on thread ' JavaBridge相关的知识，希望能为你提供帮助。
源码：

webView.evaluatejavascript("javascript:"+callBack + "(" + request + ")", new ValueCallback< String> () {
@Override
public void onReceiveValue(String value) {
Log.d(TAG, "onReceiveValue: "+value+ pin);

//SoftTokenUtil.getInstance().showDialogSoftTokenSuccess(mBaseActivity);
}
});

错误：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) {8e3ea1f} called on Looper (JavaBridge, tid 2358) {b82a469}, FYI main Looper is Looper (main, tid 1) {8e3ea1f})at android.webkit.WebView.checkThread(WebView.java:2340)at android.webkit.WebView.evaluateJavascript(WebView.java:1042)

解决方案：
在外面一层包上webView.post()方法。

webView.post(new Runnable() {
@Override
public void run() {
String request = "{‘type‘:‘CHALLENGE_OTP‘, ‘mode‘:‘ONLINE‘, ‘challengeOtp‘:‘"+pin+"‘}";
Log.d(TAG, "run: "+ "javascript:"+callBack + "(" + request + ")");
webView.evaluateJavascript("javascript:"+callBack + "(" + request + ")", new ValueCallback< String> () {
@Override
public void onReceiveValue(String value) {
Log.d(TAG, "onReceiveValue: "+value+ pin);
}
});
}
});
