QUESTION
I'm trying to start this activity_main.xlm after a user's registration flow, but when I click on the button, the app closes. I work a little time with Android but I couldn't identify this error.
I need that after clicking the register button, the app remains pressed and calls activity_main.xml
As Logcat shows, the data passes through the api {"insert":"ok"}, but the application closes and does not call activity_main.
RegisterActivity.java

Answered 2021-Dec-09 at 23:22You should not get the support action bar before setcontentview is called.
Simply, move getSupportActionBar().hide();
after setContentView(R.layout.activity_main);
and it should not crash anymore
Also please provide crash logs in the future, so we can debug quicker

QUESTION
I am loading images from Wikipedia into a Grid view. For the most part this is working correctly. Because there could possible be up to 200 or more images being loaded I am try to run it in a new thread. I see a definite delay when scrolling from my Album tab to the Artist tab that is loading the images. I am also see some lag as images are still getting load while scrolling up and down the list. Also when I scroll back to the top of the list place holders that previously occupied by the default image because I am unable to get an image from Wikipedia are now occupied by images from another artist.
When I scroll back to the song list and then back to the artist list the view is reset but it still has a lot of delay when going into the artist tab.
This image is what the screen looks like when first entering the Artist tab.
This image is what the screen looks like after scrolling to the bottom of the list and back to the top.
As you can see the

Answered 2020-Oct-14 at 16:46It looks to me as a known bug with Picasso. Try to load default image manually so it won't be replaced with cached one.
Update 14.10.20: I think the main problem is that you load network content in adapter in rather ineffective way. I suggest to form a list of all urls at first, leaving only image load in adapter.
Also reccomend you to use rerofit2 for network calls and something for async work instead of AsyncTask: rxJava, courutines, flow etc.
I created a sample project to load data async using retrofit2+coroutines.

QUESTION
I am developing an application in flutter, I am using a preloadpageview and cached video player plugin to play videos by urls from my database, after playing 15 to 20 videos, my app is shutting down and logcat is prompting error like this.

...ANSWER
Answered 2020-Oct-14 at 20:35As you see exception, you get idea that you application is consuming plenty of RAM of device.
You need to manage that memory leak in your flutter application.
Android and iOS OS allocate every application limited amount of RAM in order to manage all process at same time.
If any of application uses more RAM then their allocation, OS stops all process of that application. and we see it as crash.
In your case, you are plying multiple videos in your application, and all videos are caught videos. As they are caught videos, they are temporarily saved in RAM, and as you see more and more video, you are using more and more RAM.
You need to optimise your application, you can clear video after page changes.
With that you can control your memory leak.

Install JavaLib
You can use JavaLib like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the JavaLib component as you would do with any other Java program.
