Android - A WebView method was called on thread 'JavaBridge

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);                        }                    });                }            });
