Building App To Take Photo And Upload But Intent Data Null

I am trying to make a app that takes high quality photo and the upload them but one of the most important part won't work, the camera. Intent data is null so no image a being displ

Solution 1:

I tried this too a couple of days ago and had to struggle a lot. Then I figured it myself.

Here is how my code looks :

1) In onCreate :

capture.setOnClickListener(newView.OnClickListener() {

        @RequiresApi(api = Build.VERSION_CODES.M)@OverridepublicvoidonClick(View v) {
            if ((checkSelfPermission(Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED)) {
                if (checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
                    requestPermissions(newString[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, storagePermissionCode);
                }
                requestPermissions(newString[]{Manifest.permission.CAMERA}, cameraPermissionCode);
            } else {

                ContentValuesvalues=newContentValues();
                imageUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);

                IntentcameraIntent=newIntent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
                startActivityForResult(cameraIntent, cameraRequestCode);
            }
        }
    });

2) In onActivityResult :

@RequiresApi(api = Build.VERSION_CODES.M)@OverrideprotectedvoidonActivityResult(int requestCode, int resultCode, final Intent data) {

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

            FileOutputStreamstream=null;

            try {

                Bitmapphoto= MediaStore.Images.Media.getBitmap(getContentResolver(), imageUri);

                StringsaveFilePath= getRealPathFromURI(imageUri);

                stream = newFileOutputStream(saveFilePath);
                photo.compress(Bitmap.CompressFormat.JPEG, 25, stream);

            } catch (IOException e) {
                e.printStackTrace();
                Toast.makeText(getApplicationContext(), "Can't save image !", Toast.LENGTH_SHORT).show();
            } finally {
                try {
                    if (stream != null) {

                        stream.close();
                        Toast.makeText(getApplicationContext(), "Image saved successfully !", Toast.LENGTH_SHORT).show();
                    } else {
                        Toast.makeText(getApplicationContext(), "Can't save image, try again !", Toast.LENGTH_SHORT).show();
                    }
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }

        } elseif (resultCode == Activity.RESULT_CANCELED) {
            Toast.makeText(getApplicationContext(), "Cancelled", Toast.LENGTH_SHORT).show();
        } else {
            Toast.makeText(getApplicationContext(), "Can't capture image !", Toast.LENGTH_SHORT).show();
        }

    }
}

3) getRealPathFromURI function :

publicStringgetRealPathFromURI(Uri contentUri) {
    String[] proj = { MediaStore.Images.Media.DATA };
    Cursor cursor = managedQuery(contentUri, proj, null, null, null);
    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    return cursor.getString(column_index);
}
