安卓调用js报错webview不在同一线程A WebView method was called on thread 'JavaBridge'. All WebView methods must be called on the same thread

为js添加一个线程即可

@JavascriptInterface
public void callChangeStartTime(){
    runOnUiThread(new Runnable() {
        @Override
        public void run() {
            String call = "javascript:javaca(' 123  ')";
            webView.loadUrl(call);
        }
    });
}
