当我将url加载到WebView并尝试打开链接时,其中一些会显示错误页面,如:
net :: ERR_UNKNOWN_URL_SCHEME意图://maps.yandex.ru?utm_medium = tab ...
如何打开此链接,或者至少检查是否安装了相应的应用并运行它?
我试图通过实现自定义WebViewClient来覆盖网址加载:
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (!url.startsWith("http")) {
getActivity().startActivity(new Intent(Intent.ACTION_VIEW).setData(Uri.parse(url)));
return true;
}
return false;
}
但在这种情况下应用程序崩溃与ActivityNotFoundException。

即使安装了必需的应用,应用也会崩溃。但如果在Chrome中打开此链接,则会显示maps.yandex.ru网站,或者如果已安装,则会打开应用。
是否有常见解决方案,适用于所有intent://链接? 谢谢你的建议。
答案 0 :(得分:7)
我找到了解决方案。 This question和this documentation帮助我了解情况。
结果,我写了一个遵循这个逻辑的链接处理程序:
代码是:
from multiprocessing import Pool
pool = Pool(NUMBER_OF_CORES)
pool.map()
def f(args):
files, list1, list2 = args
dict_one = defaultdict(set)
for line in file_text:
for x in list1:
for xx in list2:
if x in line and xx in line:
dict_one[x].add(xx)
if __name__ == '__main__':
p = Pool(NUMBER_OF_CORES)
chunk_size= len(files) //NUMBER_OF_CORES
print(p.map(f, [(files[i*chunk_size:(i+1)*chunk_size], list1, list2) for i in range(NUMBER_OF_CORES)]))
也许它需要一些清理,但它可能会有所帮助。请告诉我,如果您知道更简单的方法,我仍然在寻找最佳解决方案。
