Also y get the message: "E/art: Failed sending reply to debugger: Broken pipe" before that, my code is exactly the same as in the beginning (and it runned well in the emulator, but I do some tries to change the icons of bottom nav view, and some other things but I get back everything to normality (or so I thought ) and it does not run properly. What is the possible problem ? I alredy tried to uprgrade SDK tools, and make sure my Manifest.xml includes my main activity.
The app has just the splash screen and login with Firebase alredy well done and it runned well before that. Thanks

I have never seen this error: File Share with %s from xml type layout resource
how can i fix this?

solved it:
I had an android library loaded to my project by reflection. the specified resource in the stack trace: 0x7f0a001d (my layout id) was a resource id of an appcompat component in the loaded library and the resources conflicted.
brute force solution:
create a unique layout id for my layout that doesn't conflict with the loaded library's one (by copy-pasting the original layout). obviously not the best solution
actual solution that worked for me:
the loaded library is all code and there is no native android functionality, so I have removed the appcompat v7 support library from the .gradle, making the conflicting resource to disappear

My app crashes when I try to navigate, can't seem to find issue

I can't seem to find whats wrong with my application...
Here is the logcat:

Any idea why the application crashes?

It looks like you have wrong casting: java.lang.ClassCastException: android.support.design.widget.TextInputEditText cannot be cast to android.support.design.widget.TextInputLayout
Check if you use the same types in xml and in your code, probably they are different.

This line is the problem
Caused by: java.lang.ClassCastException: android.support.design.widget.TextInputEditText cannot be cast to android.support.design.widget.TextInputLayout
Check the declared types match those in the layout file

private TextInputEditText inputEmail, inputPass;
inputEmail = (TextInputEditText) findViewById(R.id.input_log_email);
inputPass = (TextInputEditText) findViewById(R.id.input_log_pass);

Please let me know how can I resolve this as my work is stuck because of this.
Thanks in advance !!.

Regarding this ans:
Android Resources$NotFoundException: Resource ID #0x7f030027
You can check your R file for Resources$NotFoundException: Resource ID #0x7f030027. It'll tell you which resource was creating problem. As an alternative sollution I think you might have setText or any content just an int.And as you know here compiler will look for corresponding resource value. So, just concat an empty string there as ""

How to use custom fonts in Android Studio

I am attempting to use a custom font in an Android app. I placed my font files under /app/src/main/assets/fonts, and I reference them with
Typeface.createFromAsset(getApplicationContext().getAssets(),
"fonts/magorian_font.ttf")
When I run my app, I get the error:

What am I doing wrong?

add assets folder in this path : src/main/assets/font
and use this code :
Typeface typrface=Typeface.createFromAsset(getAssets(),"font/iranian_sans");
Text.setTypeface(typrface);
Update
ِDont Forget , you must copy ttf format of font in font folder

It should be look like this when you want to give a TextView a different font :)
private TextView yourtext;
yourtext= (TextView) findViewById(R.id.the_id_of_the_textview);
Typeface tf = Typeface.createFromAsset(getAssets(), "fonts/magorian_font.ttf");
yourtext.setTypeface(tf);
