Android ACTION_IMAGE_CAPTURE Intent

Question

We are trying to use the native camera app to let the user take a new picture. It works just fine if we leave out the EXTRA_OUTPUT extra and returns the small B

Answer 1

The file needs be writable by the camera, as Praveen pointed out.

In my usage I wanted to store the file in internal storage. I did this with:

Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (i.resolveActivity(getPackageManager()!=null)){
    try{
        cacheFile = createTempFile("img",".jpg",getCacheDir());
        cacheFile.setWritavle(true,false);
    }catch(IOException e){}
    if(cacheFile != null){
        i.putExtra(MediaStore.EXTRA_OUTPUT,Uri.fromFile(cacheFile));
        startActivityForResult(i,REQUEST_IMAGE_CAPTURE);
    }
}

Here cacheFile is a global file used to refer to the file which is written. Then in the result method the returned intent is null. Then the method for processing the intent looks like:

protected void onActivityResult(int requestCode,int resultCode,Intent data){
    if(requestCode != RESULT_OK){
        return;
    }
    if(requestCode == REQUEST_IMAGE_CAPTURE){
        try{
            File output = getImageFile();
            if(output != null && cacheFile != null){
                copyFile(cacheFile,output);

                //Process image file stored at output

                cacheFile.delete();
                cacheFile=null;
            }
        }catch(IOException e){}
    }
}

Here getImageFile() is a utility method to name and create the file in which the image should be stored, and copyFile() is a method to copy a file.
