大家都知道Android 版本越高存储数据要求越严格，Android 10以上，要想做到存储数据，并且实现能读取，上传下载。直接这样存储。如下代码

public String getSavePath(){String ALBUM_PATH = null;if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R){ALBUM_PATH = mContext.getExternalFilesDir(Environment.DIRECTORY_DOCUMENTS)+"/daylog/";}else {boolean sdCardExist = Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED);if (sdCardExist) {ALBUM_PATH = Environment.getExternalStorageDirectory() + File.separator+ mContext.getPackageName()+"/daylog/";}else{ALBUM_PATH = mContext.getCacheDir().toString() + File.separator+ mContext.getPackageName()+"/daylog/";}}return ALBUM_PATH;
}
