#androidproject #java #androidstudio #androidapp #rajjani

hey guys, last week i worked on simple quiz app development using android studio with java. So i recorded the basic app running app module. This will help you to develop simple quiz app. clear concept of providing data using custom array list. Used countdown timer to measure time of quiz. In this video i have recorded only basic working prototype of project. if you are developing quiz app it will give basic app but you have to put design and other stuff like fetching data from the server.

Sir I'm struggling to create two timers on the same activity where the other one is automatically selected.

For example: I want to create sort of like a game to match this two timers (00:25:50) from this one (00:00:00) then if the player matches them he won.

Thanks in advance. (Anyone)

hello I have a problem


In the 25th minute the cursor waits.
Suddenly appears:


// init conter
conter = 0;


// load ques and ans
loadQuetions (conter);


How do you do it?


Because I get an error:


error: cannot find symbol variable conter




How do I fix it?


Thank you
