Yesterday I created an account on Admob and on my app the test ads working well but the live (real) ads not showing. When I added onFaildToLoad event it returns INTERNAL_ERROR. So is there any solutions? and is it important to upload the app on play store to get live ads?
Here is my xml file:

the error
test ads is working well
If you are getting TestAds then your implementation is correct.
Change your package id and check
If you have recently created an AdUnit, then you have to wait for sometime to let the AdUnits get Activated...

Basically I have a app with two Screen. ScreenOne and ScreenTwo. In the first Screen, i mean in MainActivity viewBinding is working fine. But on a perticular button click it will redirect to the second screen. Now there is the problem.
the error massage is -

I can see that you are actually not using ViewBinding in the second activity. You are just importing it generated class. Proguard obfuscates unused classes at runtime and it is thinking that you are not using your generated view binding class (which is right, you are just importing it.) so use it as you used in the first activity. It will work.
I have to add sign in with google feature to my app. I have tried several tutorials but nothing works. Whenever I select an account from the list, that pop up gets closed and nothing happens. I don't know what is the problem since there is no errors showing on the logcat.

Im learning to use firebase to develop an app. But somehow i cannot register my user. I have look through everything and not sure what is the mistake. It kept prompting me "Failed to register" but im not sure what is the error. I have make sure that i already enabled email/password sign in method. And ive already make sure that the google play version is higher than firebase('com.google.firebase:firebase-auth:11.0.4'). Can someone please help me on this. Thank you

Dont create using firebase tools in android studio. Create manually in firebase console and it works now.
Im getting a "registration error" when I run my code and my online firebase users data is not getting updated. I checked my google play services version and updated gradle to compile with that version as I thought a later version would not work on my emulator, on my firebase project I have enabled "email/password" but my users database is not getting updated and I am throwing the "registration error" exception in my code, my password I am using is 10 characters long and contains one uppercase, some numbers and a hash just to be sure. Why is my database not getting updated, I suspected the google play services version but have downgraded this to the version my emulator is running and suspected my password but am using a more complex one but am still throwing a registration exception. I have added internet permissions on my manifest as I thought that could be a problem as well.

I finally sorted it out, it was that I required to update my system images on my API build tools and update my system images on my emulator, that got it working
This question already has answers here:

How to manually include external aar package using Gradle for Android
(26 answers)
Closed 7 years ago.
I am trying to create library project and used library code and resource to my other application, I can successfully get library activity or method which was not using any resource, but getting error when I try to use resource in activity or any method.
Here is my code.
package com.dhl.lib;
import android.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.text.InputType;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.EditText;
import android.widget.LinearLayout;
import android.widget.Toast;
public class AdditionActivity extends AppCompatActivity implements View.OnClickListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
initUI();
}
private void initUI() {
LinearLayout linearLayout = new LinearLayout(this);
linearLayout.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT));
linearLayout.setOrientation(LinearLayout.VERTICAL);
final EditText edtFirst = new EditText(this);
edtFirst.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
edtFirst.setInputType(InputType.TYPE_NUMBER_FLAG_DECIMAL);
final EditText edtSecond = new EditText(this);
edtFirst.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
edtFirst.setInputType(InputType.TYPE_NUMBER_FLAG_DECIMAL);
Button btn = new Button(this);
btn.setLayoutParams(new ActionBar.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
btn.setText("Add");
btn.setBackground(getResources().getDrawable(R.mipmap.ic_launcher));
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(AdditionActivity.this, "==> " + (Integer.parseInt(edtFirst.getText().toString().trim()) + Integer.parseInt(edtSecond.getText().toString().trim())), Toast.LENGTH_SHORT).show();
}
});
linearLayout.addView(edtFirst);
linearLayout.addView(edtSecond);
linearLayout.addView(btn);
setContentView(linearLayout);
}
#Override
public void onClick(View v) {
}
}
Here another class which used resource

}
tvAbout.setText(Html.fromHtml(aboutText));
tvAbout.setMovementMethod(LinkMovementMethod.getInstance());
new AlertDialog.Builder(activity)
.setTitle(appName + " " + versionNumber)
.setIcon(icon)
.setPositiveButton(okButtonText, null)

.show();
}
}

From that lib I can successfully get access of AdditionActivity on my Project but When I try to access About, getting error of java.lang.NoClassDefFoundError: Failed resolution of: Lcom/dhl/lib/R$layout;
Where I made mistake ? I can't found that point.
Here Is my Application app build.gradle which used library project
apply plugin: 'com.android.application'

}
** Application Main Activity Class **

btn.setOnClickListener(new View.OnClickListener() {
