ChoosePhotoHelper develops a component which facilitates the source code of picking photos in your Android apps. By using it, it's possible to pick photos from gallery or take an image with the camera without any boilerplate codes. It also internally handles some issues like rotation correction of the taken photos, permission request for camera and gallery (if needed), etc.

Take a Photo Choose from Gallery


Download

ChoosePhotoHelper is available on bintray to download using build tools systems. Add the following lines to your build.gradle file:

repositories {
    jcenter()
}

dependencies {
    implementation 'com.aminography:choosephotohelper:1.0.2'
}


Usage

First of all, ChoosePhotoHelper provides 3 types of result to access the chosen photo which are:

Builder Method Result Type
asFilePath() String
asUri() Uri
asBitmap() Bitmap

Now, use it simply in 3 steps:

• First

Create an instance of ChoosePhotoHelper using its builder pattern specifying the result type:

choosePhotoHelper = ChoosePhotoHelper.with(activity)
        .asFilePath()
        .build(new ChoosePhotoCallback<String>() {
            @Override
            public void onChoose(String photo) {
                Glide.with(MainActivity.this)
                        .load(photo)
                        .into(imageView);
            }
        });

• Second

Override onActivityResult and onRequestPermissionsResult in your Activity class, then forward their result to the choosePhotoHelper instance:

@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    choosePhotoHelper.onActivityResult(requestCode, resultCode, data);
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    choosePhotoHelper.onRequestPermissionsResult(requestCode, permissions, grantResults);
}

• Finally

Call showChooser() method on the choosePhotoHelper instance:

choosePhotoHelper.showChooser();

Here is a detailed example which is written in kotlin:

class MainActivity : AppCompatActivity() {

    private lateinit var choosePhotoHelper: ChoosePhotoHelper

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        choosePhotoHelper = ChoosePhotoHelper.with(this)
            .asFilePath()
            .build(ChoosePhotoCallback {
                Glide.with(this)
                    .load(it)
                    .into(imageView)
            })

        button.setOnClickListener {
            choosePhotoHelper.showChooser()
        }
    }

    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)
        choosePhotoHelper.onActivityResult(requestCode, resultCode, data)
    }

    override fun onRequestPermissionsResult(requestCode: Int, permissions: Array<String>, grantResults: IntArray) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults)
        choosePhotoHelper.onRequestPermissionsResult(requestCode, permissions, grantResults)
    }

}
