With the recent changes in android N, I had to upgrade my code to use FileProvider to fetch images/files using camera/file manager. The code is working fine in emulator(genymotion) but throwing IO exception in Moto G4 plus.
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.N){
try {
ParcelFileDescriptor fcd = getContentResolver().openFileDescriptor(uriOrig,"r");// uriOrig is the uri returned from camera
if(fcd != null) {
InputStream inputStream = new FileInputStream(fcd.getFileDescriptor());
uploadCall =RestService.getInstance().uploadFile(mimeType, name, size,
inputStream, defaultResponseCallback);
}
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
Here is the upload file method.
public Call<Attachment> uploadFile(final String mimeType, final String name, final long length,final InputStream is, final Callback<Attachment> callback) {
final int byteCount = 8192;
if (length > 0) {
RequestBody fileBody = new RequestBody() {
@Override
public MediaType contentType() {
return !TextUtils.isEmpty(mimeType) ? MediaType.parse(mimeType) : null;
}
@Override
public long contentLength() throws IOException {
return length;
}
@Override
public void writeTo(BufferedSink sink) throws IOException {
final long fileLength = contentLength();
byte[] buffer = new byte[byteCount];
long uploaded = 0;
try {
final Handler handler = new Handler(Looper.getMainLooper(), new Handler.Callback() {
@Override
public boolean handleMessage(Message msg) {
if (callback instanceof Callback2) {
Callback2 callback2 = (Callback2) callback;
long uploaded = (long) msg.obj;
callback2.onProgress(uploaded, fileLength);
}
return true;
}
});
int read;
while ((read = is.read(buffer)) != -1) {
uploaded += read;
sink.write(buffer, 0, read);
Log.d("write: ", "bytes: "+ new String(buffer));
Log.e("writeTo: ", uploaded + " up fd->");
// update progress on UI thread
handler.sendMessage(handler.obtainMessage(0, uploaded));
}
is.close();
} catch (IOException e) {
Log.e("file_upload", "Exception thrown while uploading", e);
}
Log.e("sink: "+uploaded + " bytes ", sink.toString(), new Exception("check"));
}
};
String fileName = name;
int index = name.lastIndexOf(".");
if (index < 0) {
String extension = MimeTypeMap.getSingleton().getExtensionFromMimeType(mimeType);
fileName += "." + extension;
}
MultipartBody.Part part = MultipartBody.Part.createFormData("file", fileName, fileBody);
Call<Attachment> call = companyRestInterface.uploadFile(part);
call.enqueue(callback);
return call;
}
}

Any help would be very much appreciated.
EDIT
The image uri part.
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File externalCacheDir = getExternalCacheDir();
File extFile = new File(externalCacheDir,
String.valueOf(System.currentTimeMillis()) + ".jpg");
mImageCaptureUri = FileProvider.getUriForFile(DirectChatActivity.this,
BuildConfig.APPLICATION_ID + ".provider",extFile);
grantUriPermission("xend.app", mImageCaptureUri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
cameraIntent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
cameraIntent.setFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, mImageCaptureUri);
This mImageCaptureUri is later referred as uriOrig. Taken all permissions and have worked accordingly.

The problem is with ParcelFileDescriptor. It closes the input stream. So replacing the line
ParcelFileDescriptor fcd = getContentResolver().openFileDescriptor(uriOrig,"r");// uriOrig is the uri returned from camera
if(fcd != null) {
InputStream inputStream = new FileInputStream(fcd.getFileDescriptor());
uploadCall =RestService.getInstance().uploadFile(mimeType, name, size,
inputStream, defaultResponseCallback);
}
with
InputStream inputStream = getContentResolver().openInputStream(uriOrig);
uploadCall =RestService.getInstance().uploadFile(mimeType, name, size,
inputStream, defaultResponseCallback);
did the work.
