If you run this code in another project, there is no error, but if you use it in this project, you will get an error. Why is that?

Is disappearing after going to another activity but showing uploading to server Glide and volley

I have created two functionality for photo uploading in my app. The first one is for capture image and the second one is for pick image from gallery. Now I have a photo API as URL. By using this API I have to upload the image at first to server and from server it will be available throught the app. Now I can successfully uploaded the picture in server and in the server side shows the picture. But in the imageview of app does not show that image. Whenever I go to another activity and then come back to image activity the imageview is empty. I have used shared preference to keep the image at image view, but that does not work.
Here is my code for photo activity

Activity associated with image cropping libraries does not destroy

I have tried to solve this problem from many different links but does not worked for me.I am using Android Image Cropper library for cropping images. Whenever i click on the button "upload image" it start the cropping activity and when i am done the cropped image is set in an imageview in "upload image" activity and after clicking "Proceed" button login is successful and i am directed to login activity but when i back press the login activity the "Upload image" activity is still there and is not destroyed. I have another activity called Update Activity that uses this Cropping activity and that activity also behaves in the same manner. So i want the "Upload image" to destroy. Thanks in advance

But the resultCode is always 0 and the data is always null. Permissions are set ofcourse.
So how can i pick images from the gallery?
I test it on Nexus 4 with Android 5.0.1

Try ACTION_PICK like this
Intent galleryIntent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(galleryIntent, RESULT_LOAD_IMG);
And on Activity result
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
try {
if (requestCode == RESULT_LOAD_IMG && resultCode == RESULT_OK
&& null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
imgDecodableString = cursor.getString(columnIndex);
cursor.close();
ImageView imgView = (ImageView) findViewById(R.id.imgView);
imgView.setImageBitmap(BitmapFactory
.decodeFile(imgDecodableString));
} else {
Toast.makeText(this, "You haven't picked Image",
Toast.LENGTH_LONG).show();
}
} catch (Exception e) {
Toast.makeText(this, "Something went wrong", Toast.LENGTH_LONG)
.show();
}
}

I was having same problem in one of my activities when I set launchMode="singleInstance" in manifest for that activity. It works fine when I remove that attribute. Although I don't know reason for this behaviour.

Image is not being displayed in child activity

Here, I have to select an image from gallery or camera. When user selects image from gallery, that selected image should be displayed to next activity. But here these both activities are under the same tab, say tab A. Means in tab A there are two activities. In first activity, user has two options to select image either from gallery or from camera. And in second activity under same tab A, user gets that selected image. But here I'm not getting the expected output. Below is my code...
MainActivity.java
public class MainActivity extends TabActivity {
TabHost tabHost;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Resources ressources = getResources();
tabHost = getTabHost();
Intent intentProfile = new Intent().setClass(this, Tab1.class);
TabSpec tabProfile = tabHost
.newTabSpec("Profile")
.setIndicator("Profile", ressources.getDrawable(R.drawable.ic_launcher))
.setContent(intentProfile);
Intent intentFriends = new Intent().setClass(this, Tab2.class);
TabSpec tabFriends = tabHost
.newTabSpec("Friends")
.setIndicator("Friends", ressources.getDrawable(R.drawable.ic_launcher))
.setContent(intentFriends);
tabHost.addTab(tabProfile);
tabHost.addTab(tabFriends);
tabHost.setCurrentTab(0);
}
public void switchTabBar(int tab) {
tabHost.setCurrentTab(tab);
}
#Override

// Called by children
