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

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.

• 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.

• 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.

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    // and 
    // your 
    // other 
    // dependencies...
}

// add external respository url in addition to having
// your preferred repository.
repositories {
    maven {
        url "https://repo.commonsware.com.s3.amazonaws.com"
    }
}

dependencies {
	compile 'net.the4thdimension:poly-picker:1.0.11'
}

Requires Android 4.0+.

Add camera permissions and required features to your AndroidManifest.xml

<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

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.

<application
		android:icon="@drawable/ic_launcher"
		android:label="@string/app_name"
		android:largeHeap="true">
		.
		.
</application>

Declare the PolyPicker activity in your AndroidManifest.xml

<activity
            android:name="nl.changer.polypicker.ImagePickerActivity" />

Start the PolyPicker activity and get the result back.

private void getImages() {
	Intent intent = new Intent(mContext, ImagePickerActivity.class);
	intent.putExtra(ImagePickerActivity.EXTRA_SELECTION_LIMIT, 3);	// allow only upto 3 images to be selected.
	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;
            }

            // show images using uris returned.
		}
	}
}

• This project is inspired by and modified from an existing project mentioned below. android-multiple-image-picker

• Dealing with camera on variety of hardware and fragmentation in underlying software is difficult. CommonsGuy's library Cwac Camera helped handle it better in this project

• android-multiple-image-picker
• MultipleImagePick

• Fix leaking progress dialog windown when the device orientation changes

• Persist captured images even on device orientation changes

• Replace camera view with CommonsGuy camera view which is tested well and handles camera functionality better on variety of hardware.
