Android Pie（9.0）WebView在多进程中

WebView.setDataDirectorySuffix("dir_name_no_separator")

java.lang.RuntimeException: Unable to create service com.myapp.service.MyService: java.lang.IllegalStateException: Can't set data directory suffix: WebView already initialized

我找不到任何例外的原因。我没有调用这个方法两次，也没有在主进程中调用它。有什么想法吗？

最佳答案：

MobileAds.initialize()ApplicationonCreate()WebViewWebView.setDataDirectorySuffix("dir_name_no_separator")onCreate()Application

IllegalStateException: Can't set data directory suffix: WebView already initialized

我怎么解决的？
我使用下面的方法获取进程名，并检查它是否是我的主进程-调用mobileads.initialize（）方法，如果它是我的第二个进程，则调用

MobileAds.initialize()

方法。
获取进程名称：

public static String getProcessName(Context context) {
    ActivityManager manager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
    for (ActivityManager.RunningAppProcessInfo processInfo : manager.getRunningAppProcesses()) {
        if (processInfo.pid == android.os.Process.myPid()) {
            return processInfo.processName;
        }
    }

    return null;
}

应用程序类oncreate（）：

if (!Utils.getProcessName(this).equals("YOUR_SECOND_PROCESS_NAME")) {
    MobileAds.initialize(this);
} else {
    WebView.setDataDirectorySuffix("dir_name_no_separator")
}
