0.234 -> hello everyone in this video I am going to show you how to solve
3.649 -> my app crashes even though there is no error in android studio code
8.505 -> so its a common mistake thats done here , I wouldn't recommend that it works 100% I don't know
14.784 -> maybe the type of error could be different but this also one of the cases in that
20.19 -> so this one works for me
22.777 -> so I will tell you this one , currently I have a code
25.607 -> simple code , I have a button and textview over here
28.923 -> and just a simple one , if I press the button
31.739 -> the testview will change to "hello" , thats it pretty straightforward and it has a function
36.718 -> and here is the reference to it and thats it
41.297 -> thats the code , its very simple, the onc (onclick function) given it over here
45.696 -> onc in onclick
49.575 -> so now I have connected my mobile phone to it and let me just run it
58.146 -> I have already ran this program and you can see here
62.027 -> installed successfully finished , but in my phone the app has already crashed
67.624 -> so first lets get to the basics
71.074 -> if your app has crashed just don't go to any other website and type "my app has crashed , how to solve it", you can solve on your own , its very simple to solve it
81.663 -> so just go to logcat , run , todo , logcat will be there
86.879 -> and here just go to , it will be actually verbose I think so
91.466 -> it will show you multiple options , you are just going to select "error"
97.659 -> just select error and in this error
104.312 -> so you are just search for the link like thing ( blue color underlined text )
107.71 -> So I have only one error actually , thats because its a small program
111.968 -> so mainactivity.java 12
114.256 -> so this is mainactivity.java and it shows error in 12
118.588 -> so click it , it will directly take us to the line
121.518 -> so whats the error , I don't have any error here
125.481 -> but still its showing an error, actually there is an error in it
129.148 -> so I will solve it , pretty much simple
133.41 -> just going to cut it
136.099 -> and paste it inside this function thats it
140.553 -> so this is the error , I think many of you would have done this
145.041 -> and your app might have crashed , this is the error thats causing it to crash
151.232 -> so whenever you declare a textview
154.542 -> it must be declared within the function (or globally at the top) , when you have a public onclick call
160.591 -> if you have onclicklistener there is no problem , you can directly declare inside the class
164.485 -> so whenever you use onclick method you need to declare it
168.539 -> inside this (or have it globally declared at the top) , so now let me just run it again
180.986 -> so now my app has run successfully
184.42 -> so now let me show you again , going to logcat
187.302 -> so you see the logcat "error" , there is no error
191.222 -> and if you go to verbose also there is no red marks
194.791 -> so that shows your app has successfully run 100% , no errors nothing
199.254 -> so this is one of the ways , I am not saying this will work or be error for you
203.338 -> but this maybe thats what I am saying
206.166 -> and thanks for watching and for many such
208.901 -> tutorials , I have done on many things in python , unity , android studio so kindly watch that
213.935 -> and subscribe and support thank you
