CameraPreferencesActivity provides a menu which allows the camera and its
resolution to be selected interactively by the user.
To use CameraPreferencesActivity in your own application, add the following
to your AndroidManifest.xml:
\
\
The activity draws on string values provided by ARXJ's strings.xml
resource.
Additionally, if your activity is not based on ARActivity, the following
additional additions must be made:
Once per install of Application and prior to using any of the camera
preferences, e.g. in Application.onCreate(), or if not subclassing
Application, in Activity.onCreate():
import android.preference.PreferenceManager;
PreferenceManager.setDefaultValues(this,
org.artoolkitx.arx.arxj.R.xml.preferences, false);
When opening the camera:
import android.os.Build; import android.preference.PreferenceManager; Camera
camera = null; if (Build.VERSION.SDK_INT \>= Build.VERSION_CODES.GINGERBREAD)
{ int cameraIndex =
Integer.parseInt(PreferenceManager.getDefaultSharedPreferences
(callingContext).getString("pref_cameraIndex", "0"));
Camera.open(cameraIndex); } else { else camera = Camera.open(); }
When configuring camera:
String camResolution =
PreferenceManager.getDefaultSharedPreferences(callingContext
).getString("pref_cameraResolution",
getResources().getString(R.string.pref_defaultValue_cameraResolution));
String[] dims = camResolution.split("x", 2); Camera.Parameters parameters =
camera.getParameters(); parameters.setPreviewSize(Integer.parseInt(dims[0]),
Integer.parseInt(dims[1])); camera.setParameters(parameters);
To determine if the camera is rear-facing or front-facing:
boolean frontFacing = false; if (Build.VERSION.SDK_INT \>=
Build.VERSION_CODES.GINGERBREAD) { Camera.CameraInfo cameraInfo = new
Camera.CameraInfo(); int cameraIndex =
Integer.parseInt(PreferenceManager.getDefaultSharedPreferences
(callingContext).getString("pref_cameraIndex", "0"));
Camera.getCameraInfo(cameraIndex, cameraInfo); if (cameraInfo.facing ==
Camera.CameraInfo.CAMERA_FACING_FRONT) frontFacing = true; }
