WebView多进程错误

Crash信息：

1、java.lang.RuntimeException: Using WebView from more than one process at once with the same data directory is not supported

2、java.lang.RuntimeException: Failed to create lock file /data/user/0/com.xxx/app_webview/webview_data.lock

3、java.io.FileNotFoundException: /data/user/0/com.xxx/app_webview/webview_data.lock: open failed: ENOENT (No such file or directory)

项目中开启了两个进程：
com.xxx.app.test 和 com.xxx.app.test.pushcore
错误原因：
Android P行为变更，不可多进程使用同一个目录webView，需要为不同进程webView设置不同目录

Fatal Exception: java.lang.RuntimeException: Using WebView from more than one process at once with the same data directory is not supported.

解决方案

官方提供方案：WebView.setDataDirectorySuffix(suffix);

Android 9 prohibit sharing WebView data directory among multiple processes
add below code in your mainApplication file

protected void attachBaseContext(Context base) {
    mApplicationContext = base;
    webViewSetPath(this);
  }  


public void webViewSetPath(Context context) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
        String processName = SpecialUtils.getCurProcessName(context);
        if(!CommonConstant.NEW_PACKAGE_NAME.equals(processName)){
            WebView.setDataDirectorySuffix(getString(processName,"这里隐藏名字，自己设置个目录"));
        }
    }
}

public String getString(String processName, String defValue) {
    return TextUtils.isEmpty(processName) ? defValue : processName;
}

从源码分析调用链最终调用到了AwDataDirLock类中的lock方法。

​public class WebViewChromiumAwInit {
 protected void startChromiumLocked() {
   ...
   AwBrowserProcess.start
