How to resolve this issue?


The problem is described in the log. You are trying to write to a location where the application cannot store data.
To get the path for writing data, you can use for example:
Context instrumentationContext = InstrumentationRegistry.getInstrumentation().getTargetContext();
targetDirectory = instrumentationContext.getFilesDir().toPath();
targetDirectory = targetDirectory.resolve("storage");
targetDirectory.toFile().mkdir();
and after that:
EmbeddedStorageManager storage = EmbeddedStorage.start(root, targetDirectory);

RuntimeException : when calling BillingClient function in in app purchase

private BillingClient billingClient = BillingClient.newBuilder(activity)
.setListener(purchasesUpdatedListener)
.enablePendingPurchases()
.build();
I am integrating billing google api for purchase but when I call this method, I get an error in place of activity.
The error is:

I think the issue here is that there is a Null Pointer in your code since the billing client has not bee instantiated.
Try modifying the code as follows
private BillingClient billingClient = BillingClient!!.newBuilder(activity)
.setListener(purchasesUpdatedListener)
.enablePendingPurchases()
.build();

kotlin.Unit cannot be cast to "Class" Dagger 2 in Android Kotlin

I am developing an Android app using Kotlin. I am trying to understand how Dagger 2 works to perform dependency injection. I am very new to Dagger 2. I am following this tutorial,https://medium.com/#elye.project/dagger-2-for-dummies-in-kotlin-with-one-page-simple-code-project-618a5f9f2fe8 to understand how it works and applying it to my project too. But I am getting an error. Following is what I have done so far.
I created an interface called AppComponent with the following code
package com.example.utils
import com.example.memento.LoginActivity
import dagger.Component
#Component
interface AppComponent
{
fun inject(app: LoginActivity)
}
I also created a class called AuthService with the following code.
package com.example.services
import javax.inject.Inject
class AuthService #Inject constructor()
{
public fun login(): String
{
return "I am logged in";
}
}
This is my LoginActivity class
class LoginActivity : AppCompatActivity()
{
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_login)
val authService = DaggerAppComponent.create().inject(this) as AuthService
tv_testing.text = authService.login();
}
}
When I run my app, I get the following error

What is wrong with my code?
I tried updating the LoginActivity to this
class LoginActivity : AppCompatActivity()
{
lateinit var authService: AuthService
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_login)
DaggerAppComponent.create().inject(this)
tv_testing.text = authService.login()
}
}
Then I got this error
kotlin.UninitializedPropertyAccessException: lateinit property authService has not been initialized
at com.example.memento.LoginActivity.onCreate(LoginActivity.kt:27)

DaggerAppComponent.create().inject(this) doesn't return anything but you're trying to cast it to AuthService. Therefore, you get ClassCastException. Instead, you should first declare AuthService as lateinit var and annotate it with #Inject. Then you can call inject() function. You can see full code below:
class LoginActivity : AppCompatActivity()
{
#Inject
private lateinit var authService: AuthService
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_login)
DaggerAppComponent.create().inject(this)
tv_testing.text = authService.login();
}
}
I hope my answer helps.

According to the the error there is error in line 91.So i try changing it but nothing seems to work
can Someone please tell me what i should do
here is a part of code which has the error
TextView text= findViewById(R.id.WP);
List<String> list = new ArrayList<String>();
list.add("A");
list.add("B");
list.add("C");
list.add("D");
list.add("E");
list.add("F");
list.add("G");
list.add("H");
list.add("I");
list.add("J");
list.add("K");
list.add("L");
list.add("M");
list.add("N");
list.add("O");
list.add("P");
list.add("Q");
list.add("R");
list.add("S");
list.add("T");
list.add("U");
list.add("V");
list.add("W");
list.add("X");
list.add("Y");
list.add("Z");
list.add("a");
list.add("b");
list.add("c");
list.add("d");
list.add("e");
list.add("f");
list.add("g");
list.add("h");
list.add("i");
list.add("j");
list.add("k");
list.add("l");
list.add("m");
list.add("n");
list.add("o");
list.add("p");
list.add("q");
list.add("r");
list.add("s");
list.add("t");
list.add("u");
list.add("v");
list.add("w");
list.add("x");
list.add("y");
list.add("z");
list.add("1");
list.add("2");
list.add("3");
list.add("4");
list.add("5");
list.add("6");
list.add("7");
list.add("8");
list.add("9");
list.add("0");
list.add(" "); for (int n=0 ;n<64;n++){
String string = Array.get(list,n).toString();
text.setText(string);}

change your for loop to this
Iterator i = list.iterator();
while (i.hasNext()) {
Log.d("string",i.next())
//your code goes here
}

My code is throwing an error [Fatal error: Main] can you tell me why?

I'm creating all the objects after onCreate and setContentView but I'm still getting the error [Fatal Error: Main] and it makes my app crash. I've seen people face the same problem but it's when they make objects for their EditText above the setContentView tag and I've tried moving it around but it's just not working for me hope you can help me. I'll provide you guys with the code... Thanks
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//-----------------------------------------------------------------------------------------------------------------------
//ASSIGNING
final EditText name=(findViewById(R.id.editText));
final EditText date=(findViewById(R.id.editText3));
EditText month=(findViewById(R.id.editText4));
final EditText year=(findViewById(R.id.editText5));
Button b=(findViewById(R.id.button));
//-----------------------------------------------------------------------------------------------------------------------
//NAME NUMBER
String s= name.getText().toString();
char[] n=s.toCharArray();
int i,total=0;
The Error I'm getting:-

That's the problem according to your error stack trace. You're trying to convert a string to a number.
