I have a zip file in my asset folder and when trying to copy this file to the external download folder I cannot open it. It seems as if the file copy does not finish as it is a few kb short of what it should be.
I am using the following code to achieve this:
using (Stream stream = activity.Assets.Open (PINPAD_FOLDER + "/" + file))
{
stream.CopyTo (System.IO.File.Create (outputPath));
stream.Close ();
}
Output folder is:
string outputPath = Path.Combine (Android.OS.Environment.GetExternalStoragePublicDirectory(Android.OS.Environment.DirectoryDownloads).AbsolutePath, filename);
All I need is to get the path to this zip file from my application which does not seem possible from the Asset directory as we can only get a stream back. Hence I am having to copy it to a directory I know the path of.
Try this one
using (Stream stream = activity.Assets.Open (PINPAD_FOLDER + "/" + file))
{
using(var fileStream = System.IO.File.Create (outputPath))
{
stream.CopyTo(fileStream );
}
}

I am using this code, but I am not able to access the expansion file content, i want to show gif image from expansion file, how can i do?
String packageName = getPackageName();
File root = Environment.getExternalStorageDirectory();
File expPath = new File(root.toString() + "/Android/obb/" + packageName);
try {
if (expPath.exists()) {
String strMainPath = expPath
+ File.separator
+ "main."
+ getPackageManager().getPackageInfo(
getPackageName(), 0).versionCode + "."
+ packageName + ".obb";
File f = new File(strMainPath);
if (f.exists()) {
Log.e("Path ", "=====>Exists");
} else {
Log.e("Path ", "=====> Not Exists");
}
ZipResourceFile zip = new ZipResourceFile(strMainPath);
InputStream iStream = zip.getInputStream("stage1_popup.gif");
BitmapFactory.Options option = new BitmapFactory.Options();
option.inPurgeable = true;
Bitmap bitmap = BitmapFactory.decodeStream(iStream, null, option);
Glide.with(SampleDownloaderActivity.this).load(bitmap).into(image);
}
} catch (Exception e) {
}

The Play APK expansions files library is completely open source, and you can see the sourcecode for ZipResourceFile here.
It looks like stage1_popup.gif is not in your obb file. To investigate it, why not use adb pull to get the file off your device and see what it actually contains. Or download the source code and attach to your IDE so you can step into the getInputStream() call and see where it is going wrong.
As mentioned in this answer, ZipResourceFile isn't able to deal with too much little files and neither is ZipFile. So try to divide your files in more directories.
Also, it's quite possible that there isn't any file with the name, stage1_popup.gif.
Alternatively, you can get all Entries via zipResourceFile.getAllEntries() and findout if the file exists.
I've got the sqlite db working in the editor just fine. However when using it in Android, I get an error saying data path not found.
I believe I have the needed libsqlite.so files in the correct plugins/ android folder and the other DLLs that the editor looks for.
Here is my code:
string filepath = Application.dataPath + "/" + "Players.db"; //.db
if(!File.Exists(filepath))
{
// if it doesn't ->
// open StreamingAssets directory and load the db ->
try {
WWW loadDB = new WWW ("jar:file://" + Application.persistentDataPath + "!/Assets/" + "StreamingAssets/Players.db"); // .db this is the path to your StreamingAssets in android
while (!loadDB.isDone) {
} // CAREFUL here, for safety reasons you shouldn't let this while loop unattended, place a timer and error check
// then save to Application.persistentDataPath
File.WriteAllBytes (filepath, loadDB.bytes);
} catch (Exception ex) {
GameObject.Find ("Advice").GetComponent<Text> ().text = ex.Message;
}
}
You are using Application.DataPath to save files. In editor mode it refers to Assets folder but in android build it refers to APK package which is a compressed file and you have no access to it. So use Application.persistentDataPath instead.
string filepath = Application.persistentDataPath + "/" + "Players.db"; //.db
I am downloading a pdf file from server and saving it on sd card without extension (for security purpose so that normal user can't open that file from file manager).For e.g.- I am downloading abc.pdf and saving it on sd card with abc on below path
String extStorageDirectory = Environment.getExternalStorageDirectory().toString();
File folder = new File(extStorageDirectory, "files");
And later I want to view that file by adding extension.
So when I am accessing that file from code by using below code then its gives error file does't exist..
String s=Environment.getExternalStorageDirectory() + "/files/" + "abc";
File pdfFile = new File(s+".pdf");
So how can I save file in sd card without extension and later open that file with extension.
Workaround for your problem is to rename your saved pdf file without extension to filename with .pdf extension & after completing/accessing view or read operation on your new pdf extension file again you can rename it to file without extension
Example Usage:
String currentFileName = Environment.getExternalStorageDirectory() + File.separator
+ "files" + File.separator + "abc";
String renamedFilename = currentFileName + ".pdf";
boolean isRenamed = renameFile(currentFileName, renamedFilename);
Log.d("isRenamed: ", "" + isRenamed);
if(isRenamed {
//perform your operation
}
Again rename the file if not in use (here exchange renameFile() parameters):
boolean renameAfterOperation = renameFile(renamedFilename, currentFileName);
Log.d("renameAfterOperation : ", "" + renameAfterOperation );
And here is renameFile(currentFilePath, renamedFilePath):
public boolean renameFile(String currentFilePath, String renamedFilePath){
File currentFile = new File(currentFilePath);
File newFile = new File(renamedFilePath);
boolean isrenamed = currentFile.renameTo(newFile);
return isrenamed;
}
In this way whenever you want to perform operation on saved file first rename it to .pdf & whenever it's not in use, again rename it without extension. Let me know if this works for you..
i would download with DownloadManager a file in a specific directory. At the beginning of my app, i create (if doesn't exist) a folder:
if (storageState.equals(Environment.MEDIA_MOUNTED)) {
externalStorageWriteable = true;
directory_path = Environment.getExternalStorageDirectory()
+ "/" + context.getResources().getString(R.string.app_name);
directory = new File(directory_path);
if (!directory.exists()) {
directory.mkdirs();
}
}
if i check with a filemanager, folder it's available at /sdcard/folderName but if i print on logcat directory_path variable, i obtain
/storage/emulated/0/folderName
I try to download file by passing destination folder like
Uri destination = Uri.fromFile(new File(directory_path));
request.setDestinationUri(destination);
//request is of type DownloadManager.Request
but when i check where file it's stored, my folder is empty and downloaded file is stored inside /sdcard/Download
Could someone tell me why and how can i solve this issue?
Add .toString()
Environment.getExternalStorageDirectory().toString()
It looks like I can not play videos stored in my internal application directory.
I have videos stored in /data/data/my.package.org/files/
And I'm trying to play a file from there using
String fpath = "/data/data/my.package.org/files/video.mpg"
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse(fpath), "video/*");
But both Android default video player and some external videoplayer (MX player) say 'this video can not be played".
Whereas when I'm saving videos to SD card they are played fine.
Why is that?
Put your video in assets folder and use this code to play video with MediaPlayer
InputStream is = getResources().getAssets().open("video.mpg");
OR
Put your video in assets folder and...
String fpath = "/data/data/my.package.org/assets/video.mpg"
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse(fpath), "video/*");
put your video in the res\raw folder. Then copy it out to the external directories where apps like video player can read them. Only your app can read /data/data/blah....
if its in res\raw, then
typeName = sourceSink.Types.video.toString();
for (sourceSink.VideoFiles video: sourceSink.VideoFiles.values() ){
resourceName = video.toString();
fileName = resourceName + ".mp4";
resource = getResources().getIdentifier(resourceName, "raw", "com.invodo.allshareplay");
createExternalStoragePublicFile(typeName,fileName,resource);
}
and then you can use this to copy it:
void createExternalStoragePublicFile(String fType, String fname, int res ) {
// Create a path where we will place our picture in the user's
// public pictures directory. Note that you should be careful about
// what you place here, since the user often manages these files. For
// pictures and other media owned by the application, consider
// Context.getExternalMediaDir().
File path = null;
if (((fType.equals(sourceSink.Types.photo.toString())) || (fType.equals(sourceSink.Types.file.toString())) ) ){
path = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES);
}
if (fType.equals(sourceSink.Types.music.toString())) {
path = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_MUSIC);
}
if (fType.equals(sourceSink.Types.video.toString())) {
path = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_MOVIES);
}
File file = new File(path, "/" + fname);
try {
// Make sure the Pictures directory exists.
path.mkdirs();
// Very simple code to copy a picture from the application's
// resource into the external file. Note that this code does
// no error checking, and assumes the picture is small (does not
// try to copy it in chunks). Note that if external storage is
// not currently mounted this will silently fail.
InputStream is = getResources().openRawResource(res);
OutputStream os = new FileOutputStream(file);
byte[] data = new byte[is.available()];
is.read(data);
os.write(data);
is.close();
os.close();
scanMedia(file);
} catch (IOException e) {
// Unable to create file, likely because external storage is
// not currently mounted.
Log.w("ExternalStorage", "Error writing " + file, e);
}
}
then it's easy - just do the second half of the answer I provided and write them out. /data/data/ folder is never going to be viewed by anything other than your app.
