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);
                        }
                    });
                }
            });
