Java.io.File - Cannot rename and move file on Android -

i can't rename/move temporary file , open it

here code used create temporary file

@override public void onsuccess(int statuscode, header[] headers, byte[] responsebody) {    //[...]    java.io.file tempfile = java.io.file.createtempfile("filetmp", "_handled", null);    fileoutputstream fos = new fileoutputstream(tempfile);    fos.write(responsebody); //responsebody (byte[]) not null    fos.close();    //[...] } 

then, (try to) save on disk

private void saveintodisk(java.io.file file) {         if (persitencymanager.isexternalstoragewritable()) {             java.io.file direvent = this.getparentevent().getdirectory();             log.d("root path", "" + direvent.getabsolutepath());             java.io.file mynewfile = new java.io.file(direvent.tostring() + "/"+identifiant+"_"+name);             log.d("file path", "" + mynewfile.getabsolutepath());             path = mynewfile.getabsolutepath();             if (!file.renameto(mynewfile)) {                 log.e("file rename", "can not rename file"); // display on console             } else {                 log.i("file rename", "filed renamed successfully");             }         } } 

the way create parent folder :

public static java.io.file getfolderstoragedir(string foldername) {         // directory user's public pictures directory.         java.io.file file = new java.io.file(environment.getexternalstoragepublicdirectory(                 environment.directory_documents), foldername);         if (!file.mkdirs()) {             if (!file.isdirectory()) {                 log.e("directory_creation", "directory not created");             }         }         return file;     } 

i message on console : "can not rename file". file.renameto(mynewfile) not work..

the path seems :

d/file path﹕ /storage/emulated/0/documents/12047/4691_test.pdf

here androidmanifest.xml

<uses-permission android:name="android.permission.write_external_storage" /> <uses-permission android:name="android.permission.read_external_storage" /> 

result : parent folder created not file ...

any idea problem ?

try instead of using raw file constructor, use method getfilestreampath provided context. say, do:

file oldfile = ctx.getfilestreampath("shoppinglists.tmp"); file newfile = ctx.getfilestreampath("shoppinglists.csv"); oldfile.renameto(newfile); 

the problem presumably new file() refers name relative program's current directory, not, , not guaranteed be, directory in internal files stored.

rename file in internal storage
