uCrop

Thanks to Yalantis for providing such a beautiful cropping (uCrop) library. This example uses the uCrop library for cropping functionality.

How to Use

Follow the below simple steps to add the library into your project.

1. Add file_provider.xml to your res -> xml foler.

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <external-cache-path
        name="cache"
        path="camera" />
</paths>

2. In AndroidManifext.xml, add CAMERA, DEXTER and STORAGE permissions. Add UCrop activity and FileProvider paths.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="info.androidhive.imagepicker">

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

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme"
        tools:ignore="GoogleAppIndexingWarning">
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:screenOrientation="portrait"
            android:theme="@style/AppTheme.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <!-- Image Picker activity -->
        <activity android:name=".ImagePickerActivity" />

        <!-- uCrop cropping activity -->
        <activity
            android:name="com.yalantis.ucrop.UCropActivity"
            android:screenOrientation="portrait"
            android:theme="@style/AppTheme.NoActionBar" />

        <!-- cache directory file provider paths -->
        <provider
            android:name="android.support.v4.content.FileProvider"
            android:authorities="${applicationId}.provider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/file_paths" />
        </provider>
    </application>

</manifest>

5. Add Dexter and uCrop dependencies to your app/build.gradle

dependencies {
    //...

    implementation "com.karumi:dexter:5.0.0"
    implementation 'com.github.yalantis:ucrop:2.2.2'
}

6. Copy ImagePickerActivity.java to your project.

7. Launch ImagePickerActivity by passing required intent data. Once the image is cropped, you can received the path of the cropped image in onActivityResult method.

public class MainActivity extends AppCompatActivity {
    private static final String TAG = MainActivity.class.getSimpleName();
    public static final int REQUEST_IMAGE = 100;

    @BindView(R.id.img_profile)
    ImageView imgProfile;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    // my button click function
    void onProfileImageClick() {
        Dexter.withActivity(this)
                .withPermissions(Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE)
                .withListener(new MultiplePermissionsListener() {
                    @Override
                    public void onPermissionsChecked(MultiplePermissionsReport report) {
                        if (report.areAllPermissionsGranted()) {
                            showImagePickerOptions();
                        } else {
                            // TODO - handle permission denied case
                        }
                    }

                    @Override
                    public void onPermissionRationaleShouldBeShown(List<PermissionRequest> permissions, PermissionToken token) {
                        token.continuePermissionRequest();
                    }
                }).check();
    }

    private void showImagePickerOptions() {
        ImagePickerActivity.showImagePickerOptions(this, new ImagePickerActivity.PickerOptionListener() {
            @Override
            public void onTakeCameraSelected() {
                launchCameraIntent();
            }

            @Override
            public void onChooseGallerySelected() {
                launchGalleryIntent();
            }
        });
    }

    private void launchCameraIntent() {
        Intent intent = new Intent(MainActivity.this, ImagePickerActivity.class);
        intent.putExtra(ImagePickerActivity.INTENT_IMAGE_PICKER_OPTION, ImagePickerActivity.REQUEST_IMAGE_CAPTURE);

        // setting aspect ratio
        intent.putExtra(ImagePickerActivity.INTENT_LOCK_ASPECT_RATIO, true);
        intent.putExtra(ImagePickerActivity.INTENT_ASPECT_RATIO_X, 1); // 16x9, 1x1, 3:4, 3:2
        intent.putExtra(ImagePickerActivity.INTENT_ASPECT_RATIO_Y, 1);

        // setting maximum bitmap width and height
        intent.putExtra(ImagePickerActivity.INTENT_SET_BITMAP_MAX_WIDTH_HEIGHT, true);
        intent.putExtra(ImagePickerActivity.INTENT_BITMAP_MAX_WIDTH, 1000);
        intent.putExtra(ImagePickerActivity.INTENT_BITMAP_MAX_HEIGHT, 1000);

        startActivityForResult(intent, REQUEST_IMAGE);
    }

    private void launchGalleryIntent() {
        Intent intent = new Intent(MainActivity.this, ImagePickerActivity.class);
        intent.putExtra(ImagePickerActivity.INTENT_IMAGE_PICKER_OPTION, ImagePickerActivity.REQUEST_GALLERY_IMAGE);

        // setting aspect ratio
        intent.putExtra(ImagePickerActivity.INTENT_LOCK_ASPECT_RATIO, true);
        intent.putExtra(ImagePickerActivity.INTENT_ASPECT_RATIO_X, 1); // 16x9, 1x1, 3:4, 3:2
        intent.putExtra(ImagePickerActivity.INTENT_ASPECT_RATIO_Y, 1);
        startActivityForResult(intent, REQUEST_IMAGE);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        if (requestCode == REQUEST_IMAGE) {
            if (resultCode == Activity.RESULT_OK) {
                Uri uri = data.getParcelableExtra("path");
                try {
                    // You can update this bitmap to your server
                    Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), uri);

                    // loading profile image from local cache
                    loadProfile(uri.toString());
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}

Once the Uri is received, you can create a bitmap and send to your server or preview on the screen.

Intent Parameters:

Param	Description
INTENT_IMAGE_PICKER_OPTION	To define source of the image Camera or Gallery. The values could be REQUEST_IMAGE_CAPTURE or REQUEST_GALLERY_IMAGE
INTENT_LOCK_ASPECT_RATIO	Pass true to lock the aspect ratio. (16x9, 1x1, 3:4, 3:2)
INTENT_ASPECT_RATIO_X	Width of aspect ratio (ex: 3)
INTENT_ASPECT_RATIO_Y	Height of the aspect ratio (ex: 4)
INTENT_IMAGE_COMPRESSION_QUALITY	The image compression quality 0 - 100. The default value is 80
INTENT_SET_BITMAP_MAX_WIDTH_HEIGHT	Pass true to limit the maximum width and height of the bitmap
INTENT_BITMAP_MAX_WIDTH	The maximum width of the cropped image
INTENT_BITMAP_MAX_HEIGHT	The maximum height of the cropped image

If you want additional options, you can customize the image picker activity.

Deleting Cached Images:

While the image are taken with camera, they will stored in cached directory. You can clear the cached images once the bitmap is utilized.

// Clearing older images from cache directory
// don't call this line if you want to choose multiple images in the same activity
// call this once the bitmap(s) usage is over
ImagePickerActivity.clearCache(this);
