    text
    copied!<p>I have an activity that allows you to record a video if you open a dialog and click on an icon. The problem is that after I stop recording it throws a NullPointerException even though the video is saved properly. According to Log Cat the error is not in my code so I tried to place "checkpoints" in my code and I found out that even the onActivityResult of my activity is executed properly so now I'm out of idea what to do.</p> <p>Here is the Log Cat: </p> <p><img src="https://i.stack.imgur.com/VOsq6.png" alt="enter image description here"></p> <p>Code:</p> <p>these are from my dialog that invokes the camera app</p> <pre><code>Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE); fileUri = getOutputMediaFileUri(MEDIA_TYPE_VIDEO); intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1); // set the video image quality to high // start the Video Capture Intent ((Activity)context).startActivityForResult(intent, CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE); private static Uri getOutputMediaFileUri(int type) { return Uri.fromFile(getOutputMediaFile(type)); } private static File getOutputMediaFile(int type) { // To be safe, you should check that the SDCard is mounted // using Environment.getExternalStorageState() before doing this. File mediaStorageDir = new File(Environment.getExternalStorageDirectory()+"/Movies", "MyCameraApp"); // This location works best if you want the created images to be shared // between applications and persist after your app has been uninstalled. // Create the storage directory if it does not exist if (! mediaStorageDir.exists()){ if (! mediaStorageDir.mkdirs()){ Log.d("MyCameraApp", "failed to create directory"); return null; } } // Create a media file name String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date()); File mediaFile; if (type == MEDIA_TYPE_IMAGE){ mediaFile = new File(mediaStorageDir.getPath() + "/" + "IMG_"+ timeStamp + ".jpg"); } else if(type == MEDIA_TYPE_VIDEO) { mediaFile = new File(mediaStorageDir.getPath() + "/" + "VID_"+ timeStamp + ".mp4"); } else { return null; } return mediaFile; } </code></pre> <p>This code was more or less copied from the android developers site. As I mentioned even the onActivityResult of my activity is executed properly(where I dismiss the dialog) after this.</p>
