Need help for Setting the Camera orientation with intent

[Cyril Preiss]

Hi, i'm trying to lock camera orientation when i take a video (launched with Misc / Send Intent, put "android.media.action.VIDEO_CAPTURE" in the Action field and set Target to "Activity".)

i have seen various things but i don't know how to use them...

1. is it possible to use this and then how ?

public static final String EXTRA_SCREEN_ORIENTATION

Added in API level 3

The name of the Intent-extra used to control the orientation of a ViewImage or a MovieView. This is an int property that overrides the activity's requestedOrientation.

See Also

• ERROR(/android.content.pm.ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED)

Constant Value: "android.intent.extra.screenOrientation"

2. i saw this java code, but can i use it in tasker (in don't know how to use javascript):

http://developer.android.com/reference/android/hardware/Camera.html#setDisplayOrientation%28int%29

 public static void setCameraDisplayOrientation(Activity activity,
         int cameraId, android.hardware.Camera camera) {
     android.hardware.Camera.CameraInfo info =
             new android.hardware.Camera.CameraInfo();
     android.hardware.Camera.getCameraInfo(cameraId, info);
     int rotation = activity.getWindowManager().getDefaultDisplay()
             .getRotation();
     int degrees = 0;
     switch (rotation) {
         case Surface.ROTATION_0: degrees = 0; break;
         case Surface.ROTATION_90: degrees = 90; break;
         case Surface.ROTATION_180: degrees = 180; break;
         case Surface.ROTATION_270: degrees = 270; break;
     }

     int result;
     if (info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
         result = (info.orientation + degrees) % 360;
         result = (360 - result) % 360;  // compensate the mirror
     } else {  // back-facing
         result = (info.orientation - degrees + 360) % 360;
     }
     camera.setDisplayOrientation(result);
 }

3. this solulion ?

protected void setOrientation() {
    int current = getRequestedOrientation();
    // only switch the orientation if not in portrait
    if ( current != ActivityInfo.SCREEN_ORIENTATION_PORTRAIT ) {
        setRequestedOrientation( ActivityInfo.SCREEN_ORIENTATION_PORTRAIT );
    }
}

There's no way I know of to call java code in Tasker.  Note java != javascript.

thank you but it doesn't do anything for the camera app :(

What is it your trying to do? 

[Cyril Preiss]

i'm using a smartwatch Omate Truesmart.

The problem is that the camera orientation is very sensitive, if i move only a little up or down it will rotate the video, so i wanted to block it.

But it's not the app that rotate, but inside the app.

Use this code from the Activity class to lock your screen. Just make sure to place it when you are coming back from the camera app.

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LOCKED);

If you want to do a check first, to see which orientation your app is at when user comes back, then do this: 

getResources().getConfiguration().orientation

That one is useful if you want to see if the orientation might equal one portrait or landscape, and it it does, then //do something. Like this:

if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {
            mImageBitmap = rotateBitmap(mImageBitmap, 90);
        }
