项目需要在远程网页里面调用app中assets目录下的某个js文件，
开始这样写的
<script src="file:///android_asset/test.js"></script>
结果运行提示：
[INFO:CONSOLE(25) ]Not allowed to load local resource: file:///android_asset/xxx
在百度搜了半天没人解决，无奈去stackoverflow
才找到有效的回答(亲测有效):
//A bit of an intrusive hack, but I worked around this issue by introducing a
//"unique token" and implementing the WebViewClient with a
//shouldInterceptRequest override.
//First, change the URL from file:///android/asset to a relative path with a
//uniquely identifying token:
<script src="**injection**www/scripts.js"></script>
Then, override shouldInterceptRequest as follows:
// Injection token as specified in HTML source
private static final String INJECTION_TOKEN = "**injection**";
webView.setWebViewClient(new WebViewClient() {
@Override
public WebResourceResponse shouldInterceptRequest(WebView view, String url) {
WebResourceResponse response = super.shouldInterceptRequest(view, url);
if(url != null && url.contains(INJECTION_TOKEN)) {
String assetPath = url.substring(url.indexOf(INJECTION_TOKEN) + INJECTION_TOKEN.length(), url.length());
try {
response = new WebResourceResponse(
"application/javascript",
"UTF8",
getContext().getAssets().open(assetPath)
);
} catch (IOException e) {
e.printStackTrace(); // Failed to load asset file
}
}
return response;
}
});
This is likely to degrade WebView performance slightly as we are calling the contains() on each resource which is attempted to be loaded, but it's the only workaround I've found to this issue.
