Android中Environment，context获取路径

String tag = "testPath";
//公有目录
LogHelper.i(tag, "getDataDirectory=" + Environment.getDataDirectory().getPath());
LogHelper.i(tag, "getDataDirectory().getParentFile=" + Environment.getDataDirectory().getParentFile().getPath());
LogHelper.i(tag, "getDownloadCacheDirectory=" + Environment.getDownloadCacheDirectory().getPath());
LogHelper.i(tag, "getRootDirectory=" + Environment.getRootDirectory().getPath());
//私有目录
LogHelper.i(tag, "getCodeCacheDir=" + ContextCompat.getCodeCacheDir(context).getPath());
LogHelper.i(tag, "getDataDir=" + ContextCompat.getDataDir(context).getPath());
LogHelper.i(tag, "getCacheDir=" +context.getCacheDir().getPath());
LogHelper.i(tag, "getExternalCacheDir=" + context.getExternalCacheDir().getPath());
LogHelper.i(tag, "getExternalFilesDir=" + context.getExternalFilesDir(null).getPath());
