Wie bekomme ich Dateipfad, wenn ich eine Datei auf den Server hochlade?

Ich entwickle eine einfache Anwendung, in der Benutzer sein Dokument zum Server hochladen kann. Ich bin in der Lage, Datei zum Server hochzuladen, aber das Problem, das ich bekomme, ist, wenn ich Datei von diesem Standort /storage/sdcard/sample.txt auswähle, kann ich hochladen, aber wenn ich die Datei von einem anderen Ort auswähle, lädt die Datei nicht und in logcat ich ich diesen Ort immer /storage/sdcard/demo.docx "demo.docx" ist Datei, die ich von anderen Ort ausgewähltWie bekomme ich Dateipfad, wenn ich eine Datei auf den Server hochlade?

wo befindet sich demo.docx auf Ihrem Gerät? – WannaBeGeek

Demo.docx befindet sich im internen Speicher –

Er bekommt FileNotFoundException, die nichts mit Content-Type zu tun hat! – kylexy1357

Sie den Pfad der Datei verwenden sollte funktionieren würde und nicht seine name.Instead von

displayName = myFile.getName();

Verwenden getPath() hier:

else if (uriString.startsWith("file://")) { 

    displayName = myFile.getPath(); 

    Log.i("tagconvertstr", "[" + displayName + "]"); 
}

Ich bekomme immer noch keinen Pfad –

Ich kann keinen Ort sehen, an dem Sie den Pfad zu Ihrer asyncTask übergeben. – kylexy1357

Sie versuchen, auf die Datei auf der externen SD-Karte zuzugreifen, während sie sich im internen Speicher befindet. Verwenden Sie den folgenden Code, um die Datei aus dem internen Speicher abzurufen:

 String filepath="directory containing file "; 
     ContextWrapper contextWrapper = new ContextWrapper(getApplicationContext()); 
     File directory = contextWrapper.getDir(filepath, Context.MODE_PRIVATE); 
     File myInternalFile = new File(directory , filename);
