How to update activity after image upload in Android

I have an activity where the user can update some data related to his profile (for example, his name) and he can also upload a new profile image.
After the update operation, the user is redirected to a new activity.
The problem is that when the user comes back to his profile activity, the showed image is still the old one and not the new one while the name updated correctly.
In order to see the new profile image, the user needs to close the app and open is again.
How can I solve this problem?
I use a function updateInfo(), but it seems to not work as I would like.
Can you help me, please?

When you turn back to your profile activity your application's task stack is bringing back your profile activity which is already in memory. So you should inform your profile activity that it was updated. In the onStart callback of your profile activity check if it is updated. If so load the new image. In short put your upDateInfo() method inside onStart().

After you update the information, in callback method onResponse you need to call updateInfo() to make an update on your UI after update of information is successfully finished. Make sure you provide new values from server especially to static variables because they will keep values as long as app is live. If you don't update them with new values they will keep old ones.
Currently on that way you are trying to update informations only in onCreate() which is called when Activity needs to be created. In this scenario it is when you exit and enter app again only by pressing Back button while on Home button it will not work as well until app is destroyed by OS.
You could also use onResume method which is called after Activity is returned from pause and that will happen when you create a new Activity upon already exiting one.

Flashlight function crashes after returning from activity

I have this android app which connects to an mqtt broker and listens for instructions to play/pause a ringtone or open/close the flashlight.
It runs as supposed to until i change my settings and call the function flashOnOff after this. Then i get a null pointer exception but i can not understand why.
This is my code (i did not include my imports to save some space):

I can provide the settings activity code too is needed

It seems that the two variables needed for the flashOnOff where not initiallized after i returned from the settings activity.
Ι added :
if (isFlashAvailable()){
camera = Camera.open();
parameters = camera.getParameters();
}
at the onActivityResult start and it works like a charm.

the result is

I think that the probleme is where is stoked my image. How I do to load my image in my application?

That is a Uri. A Uri is not a file, and so you cannot pass it to decodeFile() on BitmapFactory. Either use an image loading library like Picasso or Universal Image Loader, or have your own background thread that uses openInputStream() on a ContentResolver to read in the contents of that Uri, passing the stream to decodeStream() on BitmapFactory.

Android contact picker returning nulll (resultCode == 0)

Finally found a solution, the problem was with the android:launchMode in the manifest.

Sharing Image and Text On twitter not working

This is my code given below.FrameLayout is Used to share as JPEG Image on twitter.This is the code Im trying .
sharesp=(Spinner)findViewById(R.id.spnrShare);
sharesp.setAdapter(new MyShAdapter(MainActivity.this, R.layout.rowview, Sharestring));
sharesp.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View v,
int position, long arg3) {
// TODO Auto-generated method stub
selectitem=parent.getItemAtPosition(position).toString();
selecetint=position;
if(selectitem=="FaceBook" || selecetint==R.drawable.fbbtn){
shareFbook();
}
else if(selectitem=="Twitter" || selecetint==R.drawable.twitbtn){
shareTwitter();
}
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
public void shareTwitter(){
FrameLayout savFrame_layout=(FrameLayout)findViewById(R.id.frame);
try {
if(MainActivity.this.mainFrame_layout==null){
MainActivity.this.mainFrame_layout.setDrawingCacheEnabled(true);
MainActivity.this.mainFrame_layout.refreshDrawableState();
MainActivity.this.mainFrame_layout.buildDrawingCache();
MainActivity.this.bm_ImgFrame = mainFrame_layout.getDrawingCache();
int i1=100000;
Random random=new Random();
i1=random.nextInt(i1);
MainActivity.fname = "Quick_"+ i1 + ".jpg";
String pathy=Environment.getExternalStorageDirectory()+File.separator+"/MYAnApps";
MainActivity.this.rootFile=new File(pathy);
MainActivity.this.sdImageMainDirectory = new File(MainActivity.this.rootFile + MainActivity.fname);
FileOutputStream fileOutputStream = new FileOutputStream(MainActivity.this.sdImageMainDirectory);
bm_ImgFrame.compress(CompressFormat.JPEG, 80, fileOutputStream);
Uri uri = Uri.parse(MainActivity.this.sdImageMainDirectory.getAbsolutePath());
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("/*");
intent.setClassName("com.twitter.android", "com.twitter.android.PostActivity");
intent.putExtra(Intent.EXTRA_TEXT, "MyAndroidApp: https://play.google.com/store/apps/details?id=com.example.MyApp");
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(MainActivity.this.sdImageMainDirectory));
startActivity(intent);
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

Try using "*/*" as MIME, so you can send any generic data type.
intent.setType("*/*");
Also try changing ACTION_SEND to ACTION_SEND_MULTIPLE which specialized for delivering multiple data.
More info about ACTION_SEND_MULTPLE and handling MIME types.
