Allow user to select camera or gallery for image

Question

What I'm trying to do seems very simple, but after a few days of searching I can't quite figure it out.

I have an application that allows the user to select multiple(up to 5) images. I'm using an ImageView. When the user clicks on the ImageView, I'd like to allow them the option to

1. Select the image from the gallery, or
2. Use the camera to capture an image.

I started by using the ACTION_GET_CONTENT intent, and that works well for getting to the gallery. So then I tried using the ACTION_PICK_ACTIVITY intent to allow the user to choose camera or gallery:

Intent pickIntent = new Intent(Intent.ACTION_PICK_ACTIVITY);
Intent gallIntent=new Intent(Intent.ACTION_GET_CONTENT);
gallIntent.setType("image/*"); 
Intent camIntent = new Intent("android.media.action.IMAGE_CAPTURE");
pickIntent.putExtra(Intent.EXTRA_INTENT, camIntent);
pickIntent.putExtra(Intent.EXTRA_INTENT, gallIntent)
pickIntent.putExtra(Intent.EXTRA_TITLE, "Select Source");
startActivityForResult(pickIntent, IMAGE_SELECTOR);

But it appears I can only add one EXTRA_INTENT. The menu show up as expected, but the only options are Gallery and Files....no Camera).

Is there a better/easier way to do this that I'm missing? Thanks for any help.

This should take care of Tina's null outputFileUri issue:

private static final String STORED_INSTANCE_KEY_FILE_URI = "output_file_uri";

@Override
public void onSaveInstanceState( Bundle outState ) {
    super.onSaveInstanceState( outState );

    if ( outputFileUri != null ) {
        outState.putString( STORED_INSTANCE_KEY_FILE_URI, outputFileUri.toString() );
    }
}

@Override
public void onViewStateRestored( Bundle savedInstanceState ) {
    super.onViewStateRestored( savedInstanceState );

    if ( savedInstanceState != null ) {
      final String outputFileUriStr = savedInstanceState.getString( STORED_INSTANCE_KEY_FILE_URI );
      if ( outputFileUriStr != null && !outputFileUriStr.isEmpty() ) {
          outputFileUri = Uri.parse( outputFileUriStr );
      }
    }
}

Note: I'm using this code inside android.support.v4.app.Fragment your overridden methods might change depending on what Fragment/Activity version you're using.

Selecting camera or gallery for image in Android

I had worked hard on Camera or gallery Image Selection, and created some util class for this work. With the use of these class 'Selecting image camera or gallery is too easy' it just took 5-10 mints of your development.

Step-1: Add these classes in your code.

ImagePickerUtils :- http://www.codesend.com/view/f8f7c637716bf1c693d1490635ed49b3/

BitmapUtils :- http://www.codesend.com/view/81c1c2a3f39f1f7e627f01f67be282cf/

ConvertUriToFilePath :- http://www.codesend.com/view/f4668a29860235dd1b66eb419c5a58b5/

MediaUtils :- https://codeshare.io/5vKEMl

We need to Add these Permission in menifest :

  <uses-permission android:name="android.permission.CAMERA" />
  <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
  <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
  <uses-feature android:name="android.hardware.camera" />
  <uses-feature android:name="android.hardware.camera.autofocus" />

This class function (checkAndRequestPermissions) auto check the permission in Android-Marshmallow and Android - Nougat.

Step-2. Calling camera class for launching camera intent :

 //Create a global veriable .  
     private Uri mCameraUri;
     private static final int CAMERA_REQUEST_CODE = 100;

// Call this function when you wants to select or capture an Image.
       mCameraUri = ImagePickerUtils.createTakePictureIntent(this, CAMERA_REQUEST_CODE);

Step-3: Add onActivityResult in your Activity for receiving data from Intent

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == Activity.RESULT_OK) {
            Uri fileUri = ImagePickerUtils.getFileUriOfImage(this, data, mCameraUri);
            try {
                Bitmap bitmap = null;
                if (CAMERA_REQUEST_CODE == requestCode) {
                    bitmap = new BitmapUtils().getDownsampledBitmap(this, fileUri, imageView.getWidth(), imageView.getHeight());
                }
                if (bitmap != null)
                imageView.setImageBitmap(bitmap);

            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }

I hope it helps you, If any one having any suggestion to improve these class please add your review in comments.

Answer 3

this code will help you, in that there is two button one for Camera and another for Gallery, and Image will be displayed in ImageView

Answer 4

I also had this issue and what I did was create an AlertDialog and use the setItems() method along with the DialogInterface listener:

AlertDialog.Builder getImageFrom = new AlertDialog.Builder(Fotos.this);
getImageFrom.setTitle("Select:");
final CharSequence[] opsChars = {getResources().getString(R.string.takepic), getResources().getString(R.string.opengallery)};
getImageFrom.setItems(opsChars, new android.content.DialogInterface.OnClickListener(){

    @Override
    public void onClick(DialogInterface dialog, int which) {
        if(which == 0){
            Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
            startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
        }else
            if(which == 1){
                Intent intent = new Intent();
                intent.setType("image/*");
                intent.setAction(Intent.ACTION_GET_CONTENT);
                startActivityForResult(Intent.createChooser(intent,
                    getResources().getString(R.string.pickgallery)), SELECT_PICTURE);
            }
        dialog.dismiss();
    }
});

How to launch a single Intent to select images from either the Gallery or the Camera, or any application registered to browse the filesystem.

Rather than creating a Dialog with a list of Intent options, it is much better to use Intent.createChooser in order to get access to the graphical icons and short names of the various 'Camera', 'Gallery' and even Third Party filesystem browser apps such as 'Astro', etc.

This describes how to use the standard chooser-intent and add additional intents to that.

private Uri outputFileUri;

private void openImageIntent() {

    // Determine Uri of camera image to save.
    final File root = new File(Environment.getExternalStorageDirectory() + File.separator + "MyDir" + File.separator);
    root.mkdirs();
    final String fname = Utils.getUniqueImageFilename();
    final File sdImageMainDirectory = new File(root, fname);
    outputFileUri = Uri.fromFile(sdImageMainDirectory);

    // Camera.
    final List<Intent> cameraIntents = new ArrayList<Intent>();
    final Intent captureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    final PackageManager packageManager = getPackageManager();
    final List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);
    for(ResolveInfo res : listCam) {
        final String packageName = res.activityInfo.packageName;
        final Intent intent = new Intent(captureIntent);
        intent.setComponent(new ComponentName(packageName, res.activityInfo.name));
        intent.setPackage(packageName);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
        cameraIntents.add(intent);
    }

    // Filesystem.
    final Intent galleryIntent = new Intent();
    galleryIntent.setType("image/*");
    galleryIntent.setAction(Intent.ACTION_GET_CONTENT);

    // Chooser of filesystem options.
    final Intent chooserIntent = Intent.createChooser(galleryIntent, "Select Source");

    // Add the camera options.
    chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, cameraIntents.toArray(new Parcelable[cameraIntents.size()]));

    startActivityForResult(chooserIntent, YOUR_SELECT_PICTURE_REQUEST_CODE);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == RESULT_OK) {
        if (requestCode == YOUR_SELECT_PICTURE_REQUEST_CODE) {
            final boolean isCamera;
            if (data == null) {
                isCamera = true;
            } else {
                final String action = data.getAction();
                if (action == null) {
                    isCamera = false;
                } else {
                    isCamera = action.equals(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                }
            }

            Uri selectedImageUri;
            if (isCamera) {
                selectedImageUri = outputFileUri;
            } else {
                selectedImageUri = data == null ? null : data.getData();
            }
        }
    }
}
