The problem with an external camera in Android using MediaStore.ACTION_IMAGE_CAPTURE

We start native Camera using this code (short variant):

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, NUMBER);

Don't forget Manifest.xml

<activity

android:name=".YourActivity"

android:screenOrientation="portrait"

android:configChanges="orientation|keyboardHidden"

</activity>

In  OnActivityResult we save information got from our external Camera, but after this in some devices we have this issue:
OnActivityResult
OnResume
OnPause
OnDestroy - there we lose all information from Camera
OnCreate
OnResume

@Override

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

      super.onActivityResult(requestCode, resultCode, data);

      mObject.setImagePath(....); - for example

}

Solution in two steps:

Step 1: Add OnSaveInstanceState and onRestoreInstanceState to your Class.

YourObject mObject = new YourObject();

@Override

public void onSaveInstanceState(Bundle savedInstanceState) {

  super.onSaveInstanceState(savedInstanceState);

  if(mObject != null) savedInstanceState.putSerializable(KEY, mObject);

}

@Override

public void onRestoreInstanceState(Bundle savedInstanceState) {

  super.onRestoreInstanceState(savedInstanceState);

  YourObject obj = (YourObject) savedInstanceState.getSerializable(KEY);

  if(obj != null) mObject = obj;

}

Step 2: Add piece of code to the OnCreate method.

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

YourObject obj = null;

try {

obj = (CarsDbModel) savedInstanceState.getSerializable(KEY);

} catch(NullPointerException e) {

}

 

if(car != null) {

      mObject = car;

}

After this code we will have this queue:

OnResume
OnPause
OnSaveInstanceState
OnDestroy
OnCreate - restore Correct Object

onRestoreInstanceState

OnResume
