我將資產中的HTML文件加載到webview中。在牛軋糖的webview中瀏覽基於資產的html文件
html有鏈接到其他html資源文件。單擊鏈接在SDK <上正常工作24,但在單擊指向Nougat(SDK 24)設備上的第二個html頁面的鏈接時會產生FileUriExposedException
錯誤。
代碼從資產的HTML加載到網頁視圖:
wbHelp.loadDataWithBaseURL("file:///android_asset/", readAssetFileAsString("Index.html"), "text/html", "UTF-8", null);
和readAssetFileAsString是:
private String readAssetFileAsString(String sourceHtmlLocation)
{
InputStream is;
try
{
is = getContext().getAssets().open(sourceHtmlLocation);
int size = is.available();
byte[] buffer = new byte[size];
is.read(buffer);
is.close();
return new String(buffer, "UTF-8");
}
catch(IOException e)
{
e.printStackTrace();
}
return "";
}
的HTML是非常基本的。 的index.html
<html><a href="Page2.html">Page 2</a></html>
Page2.html
<html><h1>Page 2</h1>

我一直使用某種形式的供應商(試過比如在這個答案中:android.os.FileUriExposedException: file:///storage/emulated/0/test.txt exposed beyond app through Intent.getData() )但它沒有任何作用。
爲什麼不使用'「file:///android_asset/Index.html」'讓該文件由WebView加載? – greenapps
我認爲這是需要能夠自動加載資產的圖像,但它看起來像它的工作沒有它,但它仍然表現出相同的例外 – behelit
