Use of Android Camera

Question

Good afternoon, guys, I’m new here, so I’m sorry if I’m asking you something I’ve already talked about. Next we have an app in the company already a while ago for sdk 7, what happens is that recently requested to use the Camera for photos, as well I am using the camera Intent as below:

    Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");

    startActivityForResult(intent, 123);

and picking up the result normally as below:

     protected void onActivityResult(int requestCode, int resultCode, Intent data) {

      if (requestCode == 123) {
         if (resultCode == Activity.RESULT_OK) {

            Uri image = getLastImage();
            String caminho = getRealPathFromURI(image);

            Bitmap bitmap = BitmapFactory.decodeFile(caminho);


            // Chame este método pra obter a URI da imagem
            Uri uri = getImageUri(getApplicationContext(), bitmap);

            // Em seguida chame este método para obter o caminho do arquivo
            File file = new File(getRealPathFromURI(uri));




             System.out.println("Caminho - "+file.getPath());

        } else {
            Toast.makeText(this, "Imagem não enviada", Toast.LENGTH_LONG)
                    .show();

        }

    } else {
        Toast.makeText(this, "Request não confere", Toast.LENGTH_LONG)
                .show();

    }

    private Uri getLastImage() {
    final ContentResolver cr = getContentResolver();
    final String[] p1 = new String[] { MediaStore.Images.ImageColumns._ID,
            MediaStore.Images.ImageColumns.DATE_TAKEN };
    Cursor c1 = cr.query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, p1,
            null, null, p1[1] + " DESC");

    int imageID = 0;
    if (c1.moveToFirst()) {
        imageID = c1.getInt(0);
    }
    c1.close();
    Uri uri = Uri.withAppendedPath(
            MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
            Integer.toString(imageID));
    return uri;
}

private void Sleep(int i) {
    // TODO Auto-generated method stub

}

public Uri getImageUri(Context inContext, Bitmap inImage) {
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
    String path = Images.Media.insertImage(inContext.getContentResolver(),
            inImage, "50609", "drawing");
    return Uri.parse(path);
}

public String getRealPathFromURI(Uri uri) {
    Cursor cursor = getContentResolver().query(uri, null, null, null, null);
    cursor.moveToFirst();
    int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
    return cursor.getString(idx);
}

but unfortunately this not working very well on some gadgets, I tested on two androids 4.1.2 being LG and Samsung, I also tested on a bike G2 with android 6.0 and it worked, but on another G3 bike with same S.O and not even in Asus with 5.0.0 simply open the camera but when recording locks the mobile phones(unfortunately the mobile phones that gave problem I have not here for error test) by what I realized how to open the printing camera from lack of permission to write, I have tried several methods seen in google without success, someone has had this kind of problem, alias I have tried in several ways to get the result by date.getData(), or date.getExtras("date") where the first returns null in the latest android versions and the second hangs. if anyone has any ideas that can help me.

Answer 1

I create the Intent to camera passing the path where I want you to save the photo, so I already have the photo that was taken saved in this location.

void tirarFoto(){
    File imagesFolder = context.getExternalFilesDir(Environment.DIRECTORY_PICTURES);

    SimpleDateFormat s = new SimpleDateFormat("yyyyMMddHHmmss");
    String nomeFoto = s.format(new Date());
    nomeFoto = codigo + nomeFoto + ".jpg";

    File file = new File(imagesFolder, nomeFoto);
    mCurrentPhotoPath = file.getAbsolutePath();//variavel global
    Intent imageIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    imageIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file));
    mTipoFoto = tipofoto;
    startActivityForResult(imageIntent, CAMERA_ACTIVITY_REQUEST_CODE);
}

When I get the result from the camera I get the photo taken from the global variable I saved the path previously.

@OnActivityResult(CAMERA_ACTIVITY_REQUEST_CODE)
void onResult(int resultCode) {
    File file = new File(mCurrentPhotoPath);
    switch (resultCode) {
        case RESULT_OK:
        // salvar foto
        break;
        case RESULT_CANCELED:
            //deletar a foto
            break;
        default:
            //deletar a foto
    }
}

In case he cancels and does not take the photo I delete the created file.

I hope I’ve helped.

Answer 2

already managed to solve the problem, I followed some tips from Edileuson Dias, I will post the complete process if someone needs it is easy to use.

I made this test application to another so it may have some flaws that I fixed when transporting to my main, but this worked

I’m taking photos compressing and sending by FTP follow:

    private String latitude;
    private Boolean Erro;
    private String local;
    private String caminho;

    @Override
    protected Boolean doInBackground(String... params) {

        sistema = params[0];
        numero = params[1];
        caminho = params[2];
        longitude = params[3];
        latitude = params[4];

        ftp = new FTPClient();

        if (sistema.equals("1")) {

        }
        if (sistema.equals("2")) {
            local = "se precicar colocar em pasta diferente";
        }

        try {

            String diretorio = caminho;
            String nomeArquivo = numero + ".jpg";
            ftp.connect("www.seuendereco.com.br", 21);
            ftp.login("login", "senha");
            ftp.changeWorkingDirectory("/imagens/" + local);
            FileInputStream arqEnviar = new FileInputStream(diretorio);

            ftp.setFileTransferMode(FTP.BINARY_FILE_TYPE);
            ftp.setFileType(FTP.BINARY_FILE_TYPE);
            ftp.storeFile(nomeArquivo + "_" + latitude + "_" + longitude,
