Android

My old lg g2 had lineageOS 14 installed already. But it was showing the info about new version and I should upgrade it. My first attempt failed miserably. And I brick my phone. When I started my phone it was showing only LG logo and it was in boot loop. They call it boot loop but actually it was not really booting up. Anyway yesterday I found https://forum.xda-developers.com/showthread.php?t=2797190 and finally installed the old LG android and it started working again. you can find the kdz here https://forum.xda-developers.com/showthread.php?t=2432476 ...

While developing a small android application. I was thinking to use IntentService which is kind of a background worker for android platform. Then I found the need code and documentation and implemented yesterday. and code is compiling so today I wanted to see it in a real phone and started Caused by: android.content.ActivityNotFoundException: Unable to find explicit activity class {com.mascix.fitinsta/com.mascix.fitinsta.ServiceLayer}; have you declared this activity in your AndroidManifest.xml? From this exception I understand that I am having a problem in androidmanifest.xml and since morning I was trying to fix it. And the result is it was code problem :) ...
