Share image taking from Camera

I am developing an app which takes a picture with the camera and allows the user to share it. But the share intent isn't working. I have checked but none are working on my device. I am running the app on an Android 6.0 marshmallow tablet.
Here is my code
public class SharePic extends Activity {
static final int REQUEST_IMAGE_CAPTURE = 1;
ImageView picView;
Button shareBtn;
Bitmap imageBitmap;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_share_pic);
picView = (ImageView) findViewById(R.id.picView);
shareBtn = (Button) findViewById(R.id.shareBtn);
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
imageBitmap = (Bitmap) extras.get("data");
picView.setImageBitmap(imageBitmap);
}
}
public void share(View view){
String bitmapPath = MediaStore.Images.Media.insertImage(getContentResolver(), imageBitmap,"title", null);
Uri bitmapUri = Uri.parse(bitmapPath);
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("image/png");
intent.putExtra(Intent.EXTRA_STREAM, bitmapUri);
startActivity(Intent.createChooser(intent , "Share"));
}
}
Any help?

So, when is the share button being called.
I guess you might have to set event listener setOnClickListener on share button click in case you haven't set it in the XML
shareBtn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
share(v);
}
});

Recorded video won't show on viewVideo

I just need help on my codes, I'm using Android Studio. Everything is working fine but the recorded video won't show in viewVideo on my layout.
Here's the code:
public class MainActivity extends AppCompatActivity {
static final int REQUEST_VIDEO_CAPTURE = 1;
VideoView resultvideo;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button click = (Button)findViewById(R.id.videorec);
resultvideo = (VideoView)findViewById(R.id.videoView);
}
public void dispatchTakeVideoIntent(View v) {
Intent takeVideoIntent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
if (takeVideoIntent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(takeVideoIntent, REQUEST_VIDEO_CAPTURE);
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_VIDEO_CAPTURE && resultCode == RESULT_OK) {
Uri videoUri = data.getData();
resultvideo.setVideoURI(videoUri);
}
}
}

Uri videoUri = data.getData();
resultvideo.setVideoURI(videoUri);
// start call missing
resultvideo.start();

Play videoView on another activity

I have an ImageButton which plays the video I recorded. Everything works fine but the thing is I want to play the recorded video(resultvideo) on another activity. I'm new to Android Dev. could someone teach me how to do that, thanks!
Here's my code:
public class MainActivity extends AppCompatActivity {
ImageButton imageButton;
static final int REQUEST_VIDEO_CAPTURE = 1;
VideoView resultvideo;
MediaController mediacontroller;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
resultvideo = (VideoView)findViewById(R.id.videoView);
mediacontroller = new MediaController(MainActivity.this);
mediacontroller.setAnchorView(resultvideo);
resultvideo.setMediaController(mediacontroller);
Button click = (Button)findViewById(R.id.buttonRecord);
resultvideo = (VideoView)findViewById(R.id.videoView);
}
public void dispatchTakeVideoIntent(View v) {
Intent takeVideoIntent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
if (takeVideoIntent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(takeVideoIntent, REQUEST_VIDEO_CAPTURE);
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_VIDEO_CAPTURE && resultCode == RESULT_OK) {
Uri videoUri = data.getData();
resultvideo.setVideoURI(videoUri);
resultvideo.pause();
}
imageButton = (ImageButton) findViewById(R.id.imageButton);
{
imageButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
startActivity(new Intent(MainActivity.this, Main2Activity.class));
resultvideo.start();
}
});
}
}
}

You can send Uri of video via Intent to another activity
Intent intent = new Intent(MainActivity.this, Main2Activity.class);
intent.putExtra("VIDEO_URI", videoUri.toString());
startActivity(intent);
And then in Main2Activity in onCreate method get videoUri like this:
String uri = getIntent().getStringExtra("VIDEO_URI");
Uri videoUri = Uri.parse(uri);

ImageButton Disappearing

I have a VideoView and an ImageButton(Play Button for the video) where I record a video and play it using the ImageButton. Everything works fine but when I try to record again another video. The ImageButton disappears.
Here's my code:
public class MainActivity extends AppCompatActivity {
ImageButton imageButton;
static final int REQUEST_VIDEO_CAPTURE = 1;
VideoView resultvideo;
MediaController mediacontroller;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
resultvideo = (VideoView)findViewById(R.id.videoView);
mediacontroller = new MediaController(MainActivity.this);
mediacontroller.setAnchorView(resultvideo);
resultvideo.setMediaController(mediacontroller);
Button click = (Button)findViewById(R.id.buttonRecord);
resultvideo = (VideoView)findViewById(R.id.videoView);
}
public void dispatchTakeVideoIntent(View v) {
Intent takeVideoIntent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
if (takeVideoIntent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(takeVideoIntent, REQUEST_VIDEO_CAPTURE);
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_VIDEO_CAPTURE && resultCode == RESULT_OK) {
Uri videoUri = data.getData();
resultvideo.setVideoURI(videoUri);
resultvideo.pause();
}
imageButton = (ImageButton) findViewById(R.id.imageButton);
{
imageButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
resultvideo.start();
mediacontroller.show();
imageButton.setVisibility(View.GONE);
}
});
}
}
}

Not sure why you expect other behaviour as the only setVisibility() call on that button you got in your code is:
imageButton.setVisibility(View.GONE);
so either remove that line or make button visible again when needed by calling
imageButton.setVisibility(View.VISIBLE);
EDIT
How do I make it disappear while the video is playing and call it back when the video is finish
Use MediaPlayer's OnCompletionListener

Android - Adding item to ListView from another Activity

First of all, I've searched on many other posts and still not found a fix for it.
MainActivity contains a ListView and an ImageButton that takes to AddActivity.
This AddActivity has got a EditText (nameAddInput) and a Button(addButton).
Despite clicking this Button, the ListView in MainActivity remains empty... Don't understand why...
Here is the the code of MainActivity:
public class MainActivity extends AppCompatActivity {
static final int PICK_CONTACT_REQUEST = 0;
private ListView list;
private ArrayAdapter<String> adapter;
private ArrayList<String> arrayList;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
list = (ListView) findViewById(R.id.itemsList);
arrayList = new ArrayList<>();
adapter = new ArrayAdapter<>(this, R.layout.listview_style1, android.R.id.text1, arrayList);
}
public void onClickAddButton(View view) {
Intent i = new Intent(MainActivity.this, AddActivity.class);
startActivityForResult(i, 2);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PICK_CONTACT_REQUEST) {
if (resultCode == RESULT_OK) {
addNewItem();
}
}
}
public void addNewItem() {
Bundle addNameInfo = getIntent().getExtras();
if(addNameInfo == null)
return;
String nameInput = addNameInfo.getString("nameInput");
arrayList.add(nameInput);
list.setAdapter(adapter);
adapter.notifyDataSetChanged();
}
}
In xml file of MainActivity in the ImageButton: android:onClick="onClickAddButton"
The code of AddActivity:
public class AddActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_add);
}
public void backToMain(View view) {
Intent i = new Intent();
EditText nameAddInput = (EditText) findViewById(R.id.nameAddInput);
String userNameText = nameAddInput.getText().toString();
i.putExtra("nameInput", userNameText);
setResult(RESULT_OK, i);
finish();
}
}
In xml file of AddActivity in the Button: android:onClick="backToMain"
Hope someone can help!!
Thank you in advance!!

getIntent() returns you the intent that launched MainActivity, not the one you set in backInMain
Try the "data" variable passed to you in onActivityResult?
Also change to
startActivityForResult(i, PICK_CONTACT_REQUEST);
I'd also suggest you rename that variable 😉

set adapter just in onCreate and just call notifyDataSetChanged in addNewItem method.

the resulting value is returned in the Intent data-Parameter of the onActivityResult function, not in the intent-member of the mainActivity.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PICK_CONTACT_REQUEST) {
if (resultCode == RESULT_OK) {
addNewItem(data.getExtras().getString("nameInput");
}
}
}
...
public void addNewItem(String newItem)
...
