How to launch the camera and take a picture

Question

I\'m trying to make an Android demo. In the demo, I have to show the camera in an activity and take a picture before advancing to another activity where I can see the camera

Answer 1

Here is the code sample.

Uri mOutputFileUri;
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, mOutputFileUri); // URI of the file where pic will be stored

startActivityForResult(intent, TAKE_PICTURE_FROM_CAMERA);

Then in your onActivityResult just check the resultCode and get your image from mOutputFileUri.

You would also want to check for the external media presence and handle the issues with the camera application behavior for HTC devices.

Answer 2

In my app I use the following code to Launch the camera:

public void imageFromCamera() {
    Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
    mImageFile = new File(Environment.getExternalStorageDirectory()+File.separator+"MyApp",  
            "PIC"+System.currentTimeMillis()+".jpg");
    mSelectedImagePath = mImageFile.getAbsolutePath();
    intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(mImageFile));
    startActivityForResult(intent, TAKE_PICTURE);
}

This will save the image to the path mSelectedImagePath which is /sdcard/MyApp/.jpg.

Then you capture the return of the IMAGE_CAPTURE intent in onActivityResult and launch your activity to edit the image from there!

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK) {
        switch(requestCode) {
        case TAKE_PICTURE:
                    //Launch ImageEdit Activity
            Intent i = new Intent(this, ImageEdit.class);
                    i.putString("imgPath", "mSelectedImagePath");
                    startActivity(i);
            break;
        }
    }
}

Hope this helps!
