Android solution to simplify work with different camera apis. Include video and photo capturing features with possibility to select quality for appropriate media action etc. In current solution were used some approaches from Grafika project and Google camera samples.

Some Annca's forks that can be useful if current functionality is not enought:

• CameraFragment

Add Annca activities to the your app manifest file:

<activity
        android:name="io.github.memfis19.annca.internal.ui.camera.Camera1Activity"
        android:screenOrientation="portrait"
        android:theme="@style/ThemeFullscreen" />
<activity
        android:name="io.github.memfis19.annca.internal.ui.camera2.Camera2Activity"
        android:screenOrientation="portrait"
        android:theme="@style/ThemeFullscreen" />
<activity
        android:name="io.github.memfis19.annca.internal.ui.preview.PreviewActivity"
        android:screenOrientation="portrait"
        android:theme="@style/ThemeFullscreen" />

Don't forget to put permissions or request them:

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

A code example of the most simple using:

 AnncaConfiguration.Builder builder = new AnncaConfiguration.Builder(activity, CAPTURE_MEDIA);
 new Annca(builder.build()).launchCamera();

and thats it. You can use more extended settings i.e.:

 AnncaConfiguration.Builder videoLimited = new AnncaConfiguration.Builder(activity, CAPTURE_MEDIA);
 videoLimited.setMediaAction(AnncaConfiguration.MEDIA_ACTION_VIDEO);
 videoLimited.setMediaQuality(AnncaConfiguration.MEDIA_QUALITY_AUTO);
 videoLimited.setVideoFileSize(5 * 1024 * 1024);
 videoLimited.setMinimumVideoDuration(5 * 60 * 1000);
 new Annca(videoLimited.build()).launchCamera();

in this example you request video capturing which is limited by file size for 5Mb and predefined minimum video duration for 5 min. To achieve this result Annca will decrease video bit rate, so use it carefully to avoid unexpected result (i.e. low quality).

 @Override
  protected void onActivityResult(int requestCode, int resultCode, Intent data) {
      super.onActivityResult(requestCode, resultCode, data);
      if (requestCode == CAPTURE_MEDIA && resultCode == RESULT_OK) {
          String filePath = data.getStringExtra(AnncaConfiguration.Arguments.FILE_PATH);
      }
   }

compile 'io.github.memfis19:annca:0.3.7'

By customizing I mean change all avaliable camera controls(not camera preview) to take photos, video recording, quality settings and more in future. To be able to customize camera view you should create activity and extend it via AnncaCameraActivity<T>, where T is camera id type (due to that in camera 1 api camera ids represent as int values and in camera 2 api as string values). You should implement all requested methods. For more details please look at BaseAnncaActivity at library project. In future I will provide more detailed instructions how to do it, but anyway it is quite easy task. In case if you gave some troubles or questions, please use GitHub Issues.

-Extend your activity from AnncaCameraActivity<T>;

-Override all methods;
-For method createCameraController use Camera1Controller or Camera2Controller respectively;
-If you want to rotate your views do it inside onScreenRotation(int degrees) method;
-For setting your camera contol layout use method getUserContentView();
-If you pass some parameters to your camera via bundle please use method onProcessBundle(Bundle savedInstanceState) which will be called before getUserContentView();
-In case you need to retrieve some data from camera controller or manager use in or after method onCameraControllerReady() was called.

Sample app contains example of using square camera. Few words about it:

1. Before appearing MediaCodec and MediaMuxer there were no ways to record video from specific surface (at least with native tools) that's why in current example I'm using view resizing to achieve square preview. Look at updateCameraPreview method within SquareCameraActivity.
2. To make square photo I'm cropping origin, please look at onPhotoTaken method within SquareCameraActivity.
3. To make square video I'm cropping origin with ffmpeg library, please look at onVideoRecordStop method within SquareCameraActivity. Conclusion: Becasue of some android limitations at least before API level 18 it is not possible to record square video. That's why to make solution more less generic I'm using crop outputs approach. In future I'll implement separate solution for API level 18+ to make possible apply more custom settings for camera (shaders, custom photo/preview/video sizes without cropping etc.).

Library has not release yet, so it contains some issues.

-Improve determinig camera quality settings;
-Extend annca configuration settings;
-Add fragments supporting;
-Add opengl supporting.
