Using WebView from more than one process at once with the same data directory is not supported

错误日志：
Using WebView from more than one process at once with the same data directory is not supported

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

解决办法：

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

public void onCreate() {
        ...
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
            String processName = getProcessName(this);
            String packageName = this.getPackageName();
            if (!packageName.equals(processName)) {
                WebView.setDataDirectorySuffix(processName);
            }
        }
}

private String getProcessName(Context context) {
        if (context == null) return null;
        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;
