Here's my code : is.close(); fos.close(); Decompress d = new Decompress(productDirectory + "/downloadedfile.zip", productDirectory + "/unzipped/"); d.unzip(); File zipfile = new File(productDirectory + "/downloadedfile.zip"); zipfile.delete()

Some Android devices treat Internal Storage as SD Cards and External Storage as EXTSD

由 被刻印的时光 ゝ 提交于 2019-12-09 09:02:14
问题 I have a bunch of Android devices from different vendors. Some of them attach /mnt/sdcard to internal storage and /mnt/extsd to external storage(Scenario 1) and others attach /mnt/sdcard to external storage(Scenario 2) I think the second scenario is standard since the Android API provides a handle to this path. Now the problem is that in scenario 1, /mnt/extsd becomes readonly even with WRITE_EXTERNAL_STORAGE permission! This means I can only read data from the actual external sd card and not

Android: How to search files on sd card?

问题 How can I search files on my sd-card given an entered string? I'd like to search for "test" and want to get a list with all files that contain in the name the string "test": testfile.txt filetest.jpg thisisatestfile.xml etc. 回答1: You can use ListFiles() of Apache Commons IO, passing a RegexFileFilter FileFilter.

问题 I've created a SQLite DB using System.Data.SQLite in a console app. I've then moved this to the Windows Phone's SD card. I followed these instructions to add SQLite support to my WP8 app: https://github.com/peterhuene/sqlite-net-wp8 I locate the DB file and open it like so: ExternalStorageFile file = null; IEnumerable<ExternalStorageDevice> storageDevices = await ExternalStorage.GetExternalStorageDevicesAsync(); foreach (ExternalStorageDevice storageDevice in storageDevices) { try { file =

Create database from prestored db file on SDcard

由 ↘锁芯ラ 提交于 2019-12-08 11:03:45
问题 The database i want to import is over 5Mb. When i put the .db in asset folder i got some errors. So i split the database into smaller db files and assemble the pieces to create the database. So is there any way i can import the database from sdcard and start using the db without splitting and assembling? Thanks in advance. 回答1: Yes, there is: place the database file inside the sdcard then create a method inside a class, the method is like: public class DB_Path { public final SQLiteDatabase
