Android 4.4 开始修改了浏览器的内核导致从5.0 开始，如果App为系统应用或者Root用户，将无法使用WebView进行加载网页的操作
错误日志如下：
java.lang.UnsupportedOperationException: For security reasons, WebView is not allowed in privileged processes
针对错误修改方法：
1，替换WebView 如果只支持简单的
2，可以尝试分离把引用系统权限的部分分离成独立的app进行独立维护
3, 如果是定制版系统可以修改FrameWork层，注释掉相应的异常
public static void hookWebView() {
int sdkInt = Build.VERSION.SDK_INT;
try {
Class<?> factoryClass = Class.forName("android.webkit.WebViewFactory");
Field field = factoryClass.getDeclaredField("sProviderInstance");
field.setAccessible(true);
Object sProviderInstance = field.get(null);
if (sProviderInstance != null) {
Log.i("thi","sProviderInstance isn't null");
return;
}
Method getProviderClassMethod;
if (sdkInt > 22) {
getProviderClassMethod = factoryClass.getDeclaredMethod("getProviderClass");
} else if (sdkInt == 22) {
getProviderClassMethod = factoryClass.getDeclaredMethod("getFactoryClass");
} else {
return;
}
getProviderClassMethod.setAccessible(true);
Class<?> providerClass = (Class<?>) getProviderClassMethod.invoke(factoryClass);
Class<?> delegateClass = Class.forName("android.webkit.WebViewDelegate");
Constructor<?> providerConstructor = providerClass.getConstructor(delegateClass);
if (providerConstructor != null) {
providerConstructor.setAccessible(true);
Constructor<?> declaredConstructor = delegateClass.getDeclaredConstructor();
declaredConstructor.setAccessible(true);
sProviderInstance = providerConstructor.newInstance(declaredConstructor.newInstance());
field.set("sProviderInstance", sProviderInstance);
}
} catch (Throwable e) {
e.printStackTrace();
}
}
