PolyPicker

Android library project for selecting/capturing multiple images from the device.

Result

Caution!

Eclipse library project structure has been dropped. If you wish to use this library in your eclipse IDE, please checkout eclipse-develop. No further development will be done or merged into eclipse-develop branch.

Why?

  • Most of the apps we develop require fetching images from camera or gallery.
  • Android does not provide multi-selection of images out of the box until API 18.
  • Dealing with camera on variety of hardware and fragmentation in underlying software is difficult.
  • There are no libraries that help me multi-choose images from both camera and gallery with beautiful UX.

Features

  • Allows taking pictures from camera as well.
  • Multi-selection of images from gallery.
  • Ability to select/capture images upto a specified limit.
  • Preview thumbnails of selected images.

Requires Android 4.0+.

Getting started

Add camera permissions and required features to your AndroidManifest.xml

Request large heap memory using "largeHeap" attribute for your application. This will avoid application to crash on low memory devices. The side effect would be that your application may force other applications to be kicked out of memory. Nothing very severe.

        .
        .


Declare the PolyPicker activity in your AndroidManifest.xml with some theme that is a descendent of AppCompat.


Start the PolyPicker activity and get the result back.

private void getImages() {
        Intent intent = new Intent(mContext, ImagePickerActivity.class);
        Config config = new Config.Builder()
                .setTabBackgroundColor(R.color.white)    // set tab background color. Default white.
                .setTabSelectionIndicatorColor(R.color.blue)
                .setCameraButtonColor(R.color.green)
                .setSelectionLimit(2)    // set photo selection limit. Default unlimited selection.
                .build();
        ImagePickerActivity.setConfig(config);
        startActivityForResult(intent, INTENT_REQUEST_GET_IMAGES);
}

@Override protected void onActivityResult(int requestCode, int resultCode, Intent intent) { super.onActivityResult(requestCode, resultCode, intent);

if (resultCode == Activity.RESULT_OK) {
    if (requestCode == INTENT_REQUEST_GET_IMAGES) {
        Parcelable[] parcelableUris = intent.getParcelableArrayExtra(ImagePickerActivity.EXTRA_IMAGE_URIS);

        if (parcelableUris == null) {
            return;
        }

        // Java doesn't allow array casting, this is a little hack
        Uri[] uris = new Uri[parcelableUris.length];
        System.arraycopy(parcelableUris, 0, uris, 0, parcelableUris.length);

        if (uris != null) {
            for (Uri uri : uris) {
                Log.i(TAG, " uri: " + uri);
                mMedia.add(uri);
            }

            showMedia();
        }
    }
}

}

Testing Snapshot build

Snapshot builds are development builds that need refining and bug fixes. Open source community can greatly help in achieveing this by testing such builds and logging issues and feedback that can make PolyPicker better, together. Add snapshot dependency to your app module's build.gradle file

repositories {
    // for downloading Polypicker dependency cwac-camera
    maven {
        url "https://repo.commonsware.com.s3.amazonaws.com"
    }

// for downloading polypicker v1.0.13-SNAPSHOT
maven {
    url "https://oss.sonatype.org/content/repositories/snapshots/"
}

}

dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) compile 'com.android.support:appcompat-v7:21.0.+' // and other dependencies

// PolyPicker dependency.
compile 'net.the4thdimension:poly-picker:1.0.13-SNAPSHOT'

Start PolyPicker activity to request images.

// start polypicker activity to grab some images.

        Config config = new Config.Builder()
                .setTabBackgroundColor(R.color.white)    // set tab background color. Default white.

                .build();
        ImagePickerActivity.setConfig(config);
        startActivityForResult(intent, INTENT_REQUEST_GET_IMAGES);


// parse images returned by polypicker @Override protected void onActivityResult(int requestCode, int resuleCode, Intent intent) { super.onActivityResult(requestCode, resuleCode, intent);

if (resuleCode == Activity.RESULT_OK) {
    if (requestCode == INTENT_REQUEST_GET_IMAGES) {
        Parcelable[] parcelableUris = intent.getParcelableArrayExtra(ImagePickerActivity.EXTRA_IMAGE_URIS);

        // Java doesn't allow array casting, this is a little hack
        Uri[] uris = new Uri[parcelableUris.length];
        System.arraycopy(parcelableUris, 0, uris, 0, parcelableUris.length);

        if (uris != null) {
            for (Uri uri : uris) {
                Log.i(TAG, " uri: " + uri);
                mMedia.add(uri);
            }

            showMedia();
        }
    }
}
