Android异常解决--A WebView method was called on thread 'JavaBridge'. All WebView methods must be called

android端调用js. 使用webView.loadUrl("javascript: alert(" + data +")"); 出现异常.

异常log如下：

[html] view plain copy

W/WebView(2088): 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) {b3dbcb18} called on Looper (JavaBridge, tid 120) {b44a1af8}, FYI main Looper is Looper (main, tid 1) {b3dbcb18})

W/WebView(2088): at android.os.Handler.dispatchMessage(Handler.java:102)
W/WebView(2088): at android.os.Looper.loop(Looper.java:136)

解决方法：

webView.post(new Runnable() {
            @Override
            public void run() {
                webView.loadUrl("javascript: alert(" + data +")");
            }
});
