The error above tells you what is really happening.
You are trying to access a "resource" using findViewById(int id) when it's not existing at all.
I recommend double-checking your code that uses findViewById(...) especially the code that intercepts the onClick(View view) event.
For example if you have an xml element with an ID like this:
<... android:id="#+id/MY_EXCELLENT_ID" ... />
You might've typed it like this:
findViewById(R.id.MY_EXCELLEND_ID);

How to get path to current class file in Kotlin in Android app without getProtectionDomain

I need to get 2 things logged from the current line of code:
the current class which is currently executed
the full path to the file of this class
In Kotlin, I can get class by
this::class
or
this::class.java
Then, I should be able to get path to the file of the class via
class.getProtectionDomain().getCodeSource().getLocation().getPath()
As is advised e. g. here.
The problem is getProtectionDomain returns null for Android Activity:

Meanwhile the class is of course not null because I can successfully see its name
log(this::class.java.name)
So how can i get class file path without getProtectionDomain?

Use this rule
-keep class com.tenor.android.core.** { *; }
This will keep away all classed inside com.tenor.android.core package from getting proguarded

Invalid destinationAddress ?? what does it mean??
For example it has an error on SmsManager.java when open it just like pic below has error in import libraries
enter image description here
Could someone help what should i do?

According to the source code of SmsManager, that exception is thrown when you call sendTextMessage with a destination address parameter that is null or an empty String.
If your code to send the SMS (as per your comment) is this:
SharedPreferences panelnumber = getSharedPreferences("Prefs", MODE_PRIVATE);
String string_from_sp = panelnumber.getString("myStringName", "");
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(string_from_sp.toString(), null,
smsBody.toString(), null, null);
then it follows that string_from_sp is a null or empty String.
Given the way you are initializing that variable, either:
the "mystringName" field retrieved from the preferences is empty, or
you have the preference field name incorrect, and you are getting the default value which you have specified to be an empty String.
There is not sufficient info to explain why this happens with API 26 only ... if that is what you are saying.

finally i found the problem
problem was in layout of activity that i used NavigationView like belo :
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="230dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_main2"
app:menu="#menu/activity_main2_drawer" />
and in api 26 and higher not support

Android Studio - Application has stopped, but 0 code errors

My android application was running smoothly before i install some Android Studio updates, and asked me to upgrade gradle etc after the update been installed.
Later on, the Android Studio asked me to update my Android Emulator (Emulator Nexus 5X API 24 Android v7.0), since i've made all these changes, my application has been unable to open when i click run. But remember it has no codding errors when i debug etc.
The error message from Android Monitor is:

As the error states, you're trying to set an onClickListener on a Button that does not exist (returns null). To simplify, when you're defining your Button, you call findViewById to associate the Button in Java with an XML element, but the ID that you are passing is not valid - either you're trying to call the setOnClickListener before you call setContentView, or the ID you are passing to findViewById has a typo or simply does not exist in the XML layout file.
Some more information, such as the code to your MainActivity and the layout file, would be useful to determine the exact cause of your problem.

Yes you're right, i forgot to specify the ID for the editText and Button, that is why it wasnt possible to find them ID on XML. So i've set it up and reloaded the project and it is running smoothly now. Thanks guys for the support.
