一 什么是webViewjavascripBridge？
WebViewJavascriptBridge是移动UIView和Html交互通信的桥梁，用作者的话来说就是实现java（ios为oc）和js的互相调用的桥梁。替代了WebView的自带的JavascriptInterface的接口，使得我们的开发更加灵活和安全。
WebViewJavascriptBridge
for Android

WebViewJavascriptBridge for iOS/OSX

注意：使用4.1.5版才能跟安卓的保持一致：
pod 'WebViewJavascriptBridge','4.1.5'
二 什么是X5
- TBS2.1基于Android 5.0 WebView Blink内核（M37版本）适配定制优化，适配Android全部主流平台，可以支持移动应用App在所有Android手机上使用Blink的技术能力。TBS2.1支持Service Worker，可以帮助Web应用后台运行，提供离线访问等原生App应用体验。此外，TBS2.1在H5/CSS3支持，安全，可靠，性能方面有进一步提升。TBS2.1已经发布，将逐步在各客户端中静默升级，用户终端无需更新微信、手机QQ、QQ空间即可使用最新的TBS2.1Blink内核。
三 接入注意事项
1、X5与WebViewJavascriptBridge
private class MyWebChromeClient extends WebChromeClient {
@Override
public boolean onJsAlert(WebView view, String url, String message, JsResult result) {
return super.onJsAlert(view, url, message, result);
}
@Override
public boolean onJsConfirm(WebView view, String url, String message, JsResult result) {
return super.onJsConfirm(view, url, message, result);
}
@Override
public boolean onJsPrompt(WebView view, String url, String message, String defaultValue, JsPromptResult result) {
return super.onJsPrompt(view, url, message, defaultValue, result);
}
@Override
public void onGeolocationPermissionsShowPrompt(String origin, GeolocationPermissions.Callback callback) {
callback.invoke(origin, true, false);
super.onGeolocationPermissionsShowPrompt(origin, callback);
}
public void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType) {
if (mUploadMessage != null) return;
Log.e("openFileChooser", "openFileChooser");
mUploadMessage = uploadMsg;
selectImage();
// Intent i = new Intent(Intent.ACTION_GET_CONTENT);
// i.addCategory(Intent.CATEGORY_OPENABLE);
// i.setType("*/*");
// startActivityForResult( Intent.createChooser( i, "File Chooser" ), FILECHOOSER_RESULTCODE );
}
// For Android < 3.0
public void openFileChooser(ValueCallback<Uri> uploadMsg) {
openFileChooser(uploadMsg, "");
}
// For Android > 4.1.1
public void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType, String capture) {
openFileChooser(uploadMsg, acceptType);
}
}
- GeolocationPermissions.Callback 替换为 GeolocationPermissionsCallback
修改为：
private class MyWebChromeClient extends WebChromeClient {
@Override
public boolean onJsAlert(WebView view, String url, String message, JsResult result) {
return super.onJsAlert(view, url, message, result);
}
@Override
public boolean onJsConfirm(WebView view, String url, String message, JsResult result) {
return super.onJsConfirm(view, url, message, result);
}
@Override
public boolean onJsPrompt(WebView view, String url, String message, String defaultValue, JsPromptResult result) {
return super.onJsPrompt(view, url, message, defaultValue, result);
}
@Override
public void onGeolocationPermissionsShowPrompt(String origin, GeolocationPermissionsCallback callback) {
callback.invoke(origin, true, false);
super.onGeolocationPermissionsShowPrompt(origin, callback);
}
public void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType) {
if (mUploadMessage != null) return;
Log.e("openFileChooser", "openFileChooser");
mUploadMessage = uploadMsg;
selectImage();
// Intent i = new Intent(Intent.ACTION_GET_CONTENT);
// i.addCategory(Intent.CATEGORY_OPENABLE);
// i.setType("*/*");
// startActivityForResult( Intent.createChooser( i, "File Chooser" ), FILECHOOSER_RESULTCODE );
}
// For Android < 3.0
public void openFileChooser(ValueCallback<Uri> uploadMsg) {
openFileChooser(uploadMsg, "");
}
// For Android > 4.1.1
public void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType, String capture) {
openFileChooser(uploadMsg, acceptType);
}
}
2，X5与百度地图网页版
地图加载慢或者加载不出来的情况 ，发现是因为
1、x5没能打开GPS定位权限，建议提示将GPS、WiFi、4G网络定位都打开。
2、第一次加载百度地图去下载的网页元素太大
