Android concerning the use of multiple processes in webview

In the above Andrid P in the system, if multiple processes, and the use to webview in these processes, you may encounter the following exception Tips

java.lang.RuntimeException: Using WebView from more than one process at once with the same data directory is not supported. https://crbug.com/558377

This error could lead to exit the app to crash.

The reason is that Android P and later versions do not support simultaneous use WebView directory with the same data from multiple processes

Google is also the official solution is to give a different process to set different data directory webview

Or adding onCreate method Applicationd class onBaseContextAttached

    public void onBaseContextAttached(Context base) {
        super.onBaseContextAttached(base);
        initWebViewDataDirectory(this);
    }

/**
* 得到进程名称
* @param context
* @return
*/
public static String getProcessName(Context context) {
    try {
            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;
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    return null;
}

/**
* 为webView设置目录后缀
* @param context
*/
@RequiresApi(api = Build.VERSION_CODES.P)
public static void initWebViewDataDirectory(Context context) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
        String processName = getProcessName(context);
        if (!context.getPackageName().equals(processName)) {//判断是否是默认进程名称
            WebView.setDataDirectorySuffix(processName);
        }
    }
}
