Android Camera Video intent returns null URI

android, camera, nullpointerexception, uri, video

Solution

I fixed this by changing the video intent to something like this:

Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
String fName = "VideoFileName.mp4";
File f = new File(fName);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
startActivityForResult(intent, CAMERA_VIDEO_REQUEST);

And in the Activity Result I got the video file path as follows:

File f = new File(Environment.getExternalStorageDirectory().toString());
for (File temp : f.listFiles()) {
     if (temp.getName().equals("VideoFileName.mp4")) {
         f = temp;
         break;
     }
}
//f is the video file...

Problem

I recently got updated to Android 4.3 and the stock video camera started acting a little weird whenever I started it with an Intent from my app. At first it would just crash and say "Gallery stopped responding". After a little while, I was able to record a video, but clicking on done returned a null URI to my app, which made it crash! So I set out testing a 2.3.4 device with the same code. The video app returned a proper URI I could use on that device. The same code worked perfectly fine before I got 4.3 (had 4.2.2 stock Galaxy Nexus) Here's an activity that get a null URI from the stock camera app of 4.3 but works fine on devices with 4.2.2 and less. ``` public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Button pick = (Button) findViewById(R.id.button1); pick.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Intent takeVideoIntent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE); startActivityForResult(takeVideoIntent, 123); } }); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if(resultCode == RESULT_OK){ if(requestCode == 123){ VideoView videoView = (VideoView) findViewById(R.id.videoView1); videoView.setVideoURI(data.getData()); Log.d("Video", "URI "+data.getData()); } } super.onActivityResult(requestCode, resultCode, data); } } ``` What do I do so that this never happens? Does this mean that this will work differently with other camera apps on different manufacturer devices?
