【安卓开发】系统级APP使用webview时出错

如果你开发的APP是系统级的，即在AndroidManifest.xml的manifest下添加了android:sharedUserId="android.uid.system"，那么你在使用webview的时候可能会出现如下错误 ：Error inflating class android.webkit.WebView

错误截图

解决方式，在调用webview的activity或者fragment的setContentView()之前，调用文中末尾的initStatusBar()方法即可正常运行。

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) {

                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) {

        }

    }
