Getting IllegalArgumentException while capturing photo from Camera

Question

In my project I am using FileProvider.getUriForFile with given provider_paths.xml file:

<?xml version="1.0" encoding="utf-8"?>
<paths>
  <external-files-path name="StrengGeheim" path="/" />
</paths>

This I added in my AndroidManifest.xml inside tag:

<provider
        android:name="android.support.v4.content.FileProvider"
        android:authorities="${applicationId}.provider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/provider_paths"/>
    </provider>

This is my camera Intent code:

private void cameraIntent() {
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    fileUri = getOutputMediaFileUri();
    intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
    startActivityForResult(intent, CAMERA);
}

private Uri getOutputMediaFileUri() {
    try {
        return FileProvider.getUriForFile(getContext(), BuildConfig.APPLICATION_ID + ".provider",getOutputMediaFile());
    }
    catch (IOException ex){
        ex.printStackTrace();
        Toast.makeText(getContext(), MESSAGE_FAILED, Toast.LENGTH_SHORT).show();
    }
    return null;
}

In file Uri the path is something like this /storage/emulated/0/StrengGeheim/06673da7-876f-4a53-9a3d-288ae033f7ac and the path of storing image from gallery is also same. But still I am getting below error while capturing photo and app is closing.

This is how I am handling OnActivityResult:

 @Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == getActivity().RESULT_CANCELED) {
        return;
    }
    try {
        if (requestCode == GALLERY && data != null) {

                    Bitmap bitmap = getBitmapFromData(data, getContext());
                    File mediaFile = getOutputMediaFile();
                    String path = saveImage(bitmap, mediaFile);
                    Log.println(Log.INFO, "Message", path);
                    Toast.makeText(getContext(), MESSAGE_IMAGE_SAVED, Toast.LENGTH_SHORT).show();
                    loadImage.setImageBitmap(bitmap);
                    imageTextMessage.setVisibility(View.INVISIBLE);

        } else if (requestCode == CAMERA) {
                File file =  new File(fileUri.getPath());
                final Bitmap bitmap = BitmapFactory.decodeFile(fileUri.getPath());
                loadImage.setImageBitmap(bitmap);
                saveImage(bitmap, file);
                Toast.makeText(getContext(), MESSAGE_IMAGE_SAVED, Toast.LENGTH_SHORT).show();
                imageTextMessage.setVisibility(View.INVISIBLE);
        }
    } catch (Exception ex) {
        ex.printStackTrace();
        Toast.makeText(getContext(), MESSAGE_FAILED, Toast.LENGTH_SHORT).show();
    }
}

private Bitmap getBitmapFromData(Intent intent, Context context){
    Uri selectedImage = intent.getData();
    String[] filePathColumn = { MediaStore.Images.Media.DATA };
    Cursor cursor = context.getContentResolver().query(selectedImage,filePathColumn, null, null, null);
    cursor.moveToFirst();
    int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
    String picturePath = cursor.getString(columnIndex);
    cursor.close();
    return BitmapFactory.decodeFile(picturePath);
}

private String saveImage(Bitmap bmpImage, File mediaFile) {
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    bmpImage.compress(Bitmap.CompressFormat.PNG, 100, bytes);
    try {
        FileOutputStream fo = new FileOutputStream(mediaFile);
        fo.write(bytes.toByteArray());
        MediaScannerConnection.scanFile(getContext(),
                new String[]{mediaFile.getPath()},
                new String[]{"image/png"}, null);
        fo.close();

        return mediaFile.getAbsolutePath();
    } catch (IOException ex) {
        ex.printStackTrace();
    }
    return "";
}

Can someone help, please?

<paths>
  <external-files-path name="StrengGeheim" path="/" />
</paths>

This configuration is for files stored under getExternalFilesDir(). That is not where your files are stored, based on your error. Change this to:

<paths>
  <external-path name="StrengGeheim" path="."/>
</paths>

But path is required attribute in android.

CommonsWare Over a year ago

@JaiPrak: name is required in FileProvider metadata. path is not. In your case, you could set the path to also be StrengGeheim, since that is where the file is located.

I put name and path same as StrengGeheim in above xml but no luck new path is /StrengGeheim/f8ed9663-7a60-436f-ade7-f94761b3ead0.png and getting FileNotFoundException.

CommonsWare Over a year ago

@JaiPrak: This is a different exception than before. Most likely, that is coming from your new File(fileUri.getPath()) call, which is wrong. You had the right File object to use -- it is what you passed to FileProvider. Use that File.

No luck still getting FileNotFoundException.
