android 高版本允许系统应用调用webview

Posted 2023-03-14

参考技术A 方式1：修改系统源码

android\frameworks\base\core\java\android\webkit\WebViewFactory

@UnsupportedAppUsage

    static WebViewFactoryProvider getProvider()

        synchronized (sProviderLock)

            // For now the main purpose of this function (and the factory abstraction) is to keep

            // us honest and minimize usage of WebView internals when binding the proxy.

            if (sProviderInstance != null) return sProviderInstance;

            final int uid = android.os.Process.myUid();

            if (uid == android.os.Process.ROOT_UID || uid == android.os.Process.SYSTEM_UID ||uid == android.os.Process.PHONE_UID || uid == android.os.Process.NFC_UID|| uid == android.os.Process.BLUETOOTH_UID)

                throw new UnsupportedOperationException(

                        "For security reasons, WebView is not allowed in privileged processes");

           

         ........



去掉其中的 uid == android.os.Process.ROOT_UID || uid == android.os.Process.SYSTEM_UID
