I have been trying to connect to parse server and amazon web services to create a login database.
Currently, I have connected the server and the amazon web services. However, now when I add the buttons for the login details and after writing the associated code, the buttons does not show when the app is running even after I have applied constraints.
This file has been downloaded by a Udemy course that I am currently doing. The file is an old file and I had several errors that I had to fix with regards to gradle files, missing toolboxes etc.
in my Logcat, I get the following information

need to find out the mistake and why app crashes
Where have you set the values for the email and password when you are authenticating with firebase?
In your code, you are doing binding.email.getText().toString() and binding.pwd.getText().toString(). These are potentially empty as I am not seeing you set the value of those views either in your xml or in your code and hence the exception is being thrown.
Just try setting those in your xml or via code and try authentication, it should work.
Building an app in Android Studio. In the logcat I get an infinite display of:
"I/art: Enter while loop."
The app works like a charm but it still looks weird. On Google I couldn't find anything and here on stack I found one reference with a very specific situation and a very specific solution.
Problem is that in my case it even shows up when I just run an 'empty activity' on my phone.
Currently using: API 19: Android 4.4 (KitKat) but have also tried on higher API's.
If any other files (gradle/manifest) are needed please let me know, hope someone can tell me whats going on (or maybe this is even normal?).
Thanks.

Though I don't see evident reasons for the problem in your empty Activity, in my case it was some logics excessively repeated many times and overloading Android Runtime what made screen be held for some time and a I/art: Enter while loop. message in console logs.
The problem was solved by reducing logics to only one pass. You can also try doing it on a separate thread.
It looks like it's some kind of debugging message what was left in Android Studio or some of the dependencies your software has.
You should try to update every library, the Android Studio and it's components to latest version and that will solve the issue.
Ive been trying from a very long time to send a string from android app to esp8266 through Telnet. I wish to see the output on serial monitor of arduino IDE.I have used the code from send string to esp8266 via android using telnet
Here are the logs that Im getting on running my android code on connecting connect and send button.

One question upfront: Are you using SoftwareSerial or HardwareSerial to talk to the ESP8266? Using SoftwareSerial is not going to make you happy.
Note 0:
At least try this code and let us know if it works for you or not. Because in theory this should work, but it doesn't
Note 1:
There is no error in this code it simply doesn't work if you are on any Constraint layout above alpha-7. However, I'm putting the logcat.

Please refer to this post for an answer .... ConstraintLayout 1.0.2 shows nothing
I know this is both "This post and the linked post" are mine, also the answer. But I been looking for an answer for almost a year. I finally found that older versions of ConstraintLayout will, for some reason, be added on top of the activity. Newer versions of ConstraintLayout fragment will be put in back of the activity. or at least that's what it looks to me. That's why I'm saying make your activity transparent.
I am building an android application that has two versions.One with Ad. and one with out Ad. . I've successfully integrated the AdMob in the application. but the Ads are not getting displayed on the screen.
Here's my

adView.loadAd(adRequest);
}
}
The ad is no getting displayed on the screen, and the logcat says...

PS: I've a good internet connection and valid AdUnitId. I don't have any kind of AdBlock applications in my device. I've also read all SO threads about this problem, but none of them worked for me.
What am i doing wrong here ? :(
I had the same issue and I fixed it by updating Google Play Services to the latest version on my mobile. So maybe try updating it from Play Store.
