从Android Pie（API 28）开始，Google不允许在2个不同的进程中使用单个WebView实例。

说明文件： https //developer.android.com/reference/android/webkit/WebView.html#setDataDirectorySuffix(java.lang.String）

根据要求，我打电话给我，WebView.setDataDirectorySuffix("dir_name_no_separator")但不幸的是，我得到了一个例外。我试图在第二个进程Service onCreate（）中调用此方法。

java.lang.RuntimeException: Unable to create service com.myapp.service.MyService: java.lang.IllegalStateException: Can't set data directory suffix: WebView already initialized
        at android.app.ActivityThread.handleCreateService(ActivityThread.java:3544)
        at android.app.ActivityThread.access$1300(ActivityThread.java:199)
        at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1666)
        at android.os.Handler.dispatchMessage(Handler.java:106)
        at android.os.Looper.loop(Looper.java:193)
        at android.app.ActivityThread.main(ActivityThread.java:6669)
        at java.lang.reflect.Method.invoke(Native Method)
        at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:493)
        at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:858)
     Caused by: java.lang.IllegalStateException: Can't set data directory suffix: WebView already initialized
        at android.webkit.WebViewFactory.setDataDirectorySuffix(WebViewFactory.java:136)
        at android.webkit.WebView.setDataDirectorySuffix(WebView.java:2165)
        at com.myapp.service.MyService.onCreate(MyService.java:134)

我找不到该异常的任何原因。我没有两次调用此方法，也没有在主过程中调用它。有任何想法吗？
