Use getFilesDir()for that.
getFilesDir()为此使用。
From the docs:
从文档：
Returns the absolute path to the directory on the filesystem where files created with openFileOutput(String, int) are stored.
No permissions are required to read or write to the returned path, since this path is internal storage.
返回文件系统上存储使用 openFileOutput(String, int) 创建的文件的目录的绝对路径。
读取或写入返回的路径不需要任何权限，因为此路径是内部存储。
To answer your comment, I'll quote the docs docs:
为了回答您的评论，我将引用 docs docs：
By default, files saved to the internal storage are private to your application and other applications cannot access them (nor can the user). When the user uninstalls your application, these files are removed.
默认情况下，保存到内部存储的文件对您的应用程序是私有的，其他应用程序无法访问它们（用户也不能）。当用户卸载您的应用程序时，这些文件将被删除。

public File createDir() {
FIle DIR=null;
if (android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED))
DIR=new File(android.os.Environment.getExternalStorageDirectory()+DIRNAME);
else
DIR=context.getCacheDir();
if(!DIR.exists())
DIR.mkdirs();
return DIR;
}
This one i m using in one of my application and which creates the directory in external if it is mounted or not exists it will create in internal storage
我在我的一个应用程序中使用了这个，如果它已安装或不存在，它将在外部创建目录，它将在内部存储中创建

You can use this:
你可以使用这个：
File f = new File(Environment.getDataDirectory(), "subdir");
