Take Photo with Camera Samsung galaxy s5 destroy activity

Question

I am working on app which uses an ImageView to display a photo. But after a photo is taken, it is not being shown in the ImageView. Furthermore, the app gets force closed after taking the picture. I try this with my Nexus 5 (Marshmallow), Samsung Galaxy S4(Lollipop & CustomRom), Xiaomi Mi4, Asus Zenfone 1, and Lenovo tablet which all run smoothly. Here are some scenarios that I tried with the Samsung Galaxy S5 :

• Take a photo, wait a couple of seconds before clicking "Ok", then I press back to my apps. (Result : sometimes this works, sometimes image does not show in the ImageView)
• Take a photo and immediately click "Ok". (Result : force closed. Logcat says TextView in abstract class is null )
• Take a photo, immediately click "Ok" while debuging in function OnActivityResult (Result : it works)

Here's the code :

AndroidManifest.xml

                    .into(img_catalog);
    }
}

StockBarangAction.java is a fragment that call intent camera, the result catch by KantinActivity(Extend BaseActivity) where the image get resize using "GeneralizeImage" function, then sent back to fragment with "setFileImageCatalog" function.

What I want to know is :

• does the camera app on the Samsung Galaxy S5 really have problem ?
• Why my apps get killed and some components become null (like TextView). I try to "findViewId" again, but its still not working. Do i need to save the textview instance?

Thank you and sorry for my English.

Answer 1

Most likely, your process is being terminated while your app is in the background. This is perfectly normal. You will get a fresh process when needed, and the user may be returned to whatever activity they had been on previously.

Your app needs to handle this case, because it is not only going to happen when you take a picture — it can happen for other reasons as well:

• User is in your app
• User presses HOME
• Five minutes later, Android terminates your process to free up system RAM for other processes
• Two minutes after that, the user goes back to your app (home screen launcher icon, overview/recent-tasks screen, etc.)

No.

Do i need to save the textview instance ?

That is not possible.
