ImageView is not showing image in Xiomi Smartphone

I have written a program to browse image gallery and show the selected image in the ImageView using AndroidStudio. I have got a sample code from Select Image From Gallery And Display It On ImageView, Issue On Nexus 5
It is working well in stock android running Smartphone like LG L70 set. But no image is visible on the imageview for Xiomi 4A.
For experimentation, I have written the same code in Eclipse editor. The code developed by Eclipse running well both LG L70 and Xiomi 4A.
Hence, it is clear that code is not problem. The problem must be from IDE. Could you please help me to solve this problem. Where should I modify the code, so that it will run on Xiomi developed by AndroidStudio.
Codes in gdrive.

You cannot use findViewById until after you call setContentView(...) in onCreate().
First only declare your ImageView
private ImageView mImageView;
and then assign it in onCreate()
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mImageView = (ImageView) findViewById(R.id.imageView);
}

Select Image from Gallery Not Posting to App in Android Studio?

I am really new and been looking through a few tutorials on Android Studio to get some help to make a simple imageview that just picks an image from gallery and displays it on the page. I can get it click and pull up gallery but it wont display after choosing the image from gallery. I looked over a few tutorials and I dont see anything I am missing? Any help?

Use this
requestCode == 1
and not
requestCode == 11
because you put 1 on the requestCode param when you call startActivityForResult()

Why placing a call programatically gives error message "Internet Calling not Supported"?

This is my code:
public String a_number;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_make_the_call);
//
callButton = (ImageButton)findViewById(R.id.call_button);
aCall = (TextView)findViewById(R.id.number_a);
a_number = aCall.getText().toString();
}
public void makeCallFunction(View view) {
String temp = "";
temp = "tel:"+a_number;
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse(temp));
startActivity(callIntent);
}
My XML file contains:
<ImageButton
android:id="#+id/call_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
android:src="#drawable/dial"
android:onClick="makeCallFunction"/>
I have added the following in my manifest file:
<uses-permission android:name="android.permission.CALL_PHONE"/>
I searched my best for answers but found nothing helpful..
EDIT:
When I give a value directly, the call gets placed now.
Eg:
callIntent.setData(Uri.parse("tel:9876543210"));
But the problem remains when I read the number from my text view and try to place call with that number.
Can someone help me out?
Thanks in advance
If there's some alternate way to implement call, that'd help too.

Disable SIP Internet Calling and VoIP on your emulator or debugging device. This is the steps for Samsung Galaxy S4 :
go to settings > call > disable internet calling(in bottom)
I don't know what you are doing wrong, but see for yourself a working example :

You can see I'm not using a hardcoded number. Make sure you enter a valid number. That's it.
