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("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
}

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);

I go to activity from two fragment and i pass extras through intent the first intent is data
Intent intent = new Intent(getContext(), AllAlbumImgActivity.class);
photoGrapherSavedPhoto.albumName=getResources().getString(R.string.photos);
intent.putExtra(SELECTED_IMG_ID, photoGrapherSavedPhoto.id);
intent.putExtra(LIST_NAME, getActivity().getResources().getString(R.string.photos));
intent.putExtra(LIST_TYPE, CURRENT_PHOTOGRAPHER_PHOTOS_LIST);
intent.putExtra(CURRENT_PAGE, nextPageUrl);
intent.putParcelableArrayListExtra(ALL_ALBUM_IMAGES, (ArrayList<? extends Parcelable>) photoGrapherPhotoList);
intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
startActivityForResult(intent, ALBUM_LIST_REQUEST_CODE);
and it worked fine
the second intent
Intent intent = new Intent(getContext(), AllAlbumImgActivity.class);
photoGrapherSavedPhoto.albumName="Saved";
intent.putExtra(SELECTED_IMG_ID, photoGrapherSavedPhoto.id);
intent.putExtra(LIST_NAME, getActivity().getResources().getString(R.string.saved));
intent.putExtra(LIST_TYPE, CURRENT_PHOTOGRAPHER_SAVED_LIST);
intent.putExtra(CURRENT_PAGE, nextPageUrl);
intent.putParcelableArrayListExtra(ALL_ALBUM_IMAGES, (ArrayList<? extends Parcelable>) photoGrapherSavedPhotoList);
intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
startActivityForResult(intent, ALBUM_LIST_REQUEST_CODE);
but it doesn't work fine with second intent data
here is how i receive the data
if (intent.getSerializableExtra(LIST_TYPE) != null)
photosListType = (Constants.PhotosListType) intent.getSerializableExtra(LIST_TYPE);
if (intent.getStringExtra(LIST_NAME) != null)
topBarTitle.setText(intent.getStringExtra(LIST_NAME));
if (photosListType == CURRENT_PHOTOGRAPHER_PHOTOS_LIST || photosListType == CURRENT_PHOTOGRAPHER_SAVED_LIST) {
nextPageUrl = intent.getStringExtra(CURRENT_PAGE);
}
if (intent.getParcelableArrayListExtra(ALL_ALBUM_IMAGES) != null) {
this.albumImgList = intent.getParcelableArrayListExtra(ALL_ALBUM_IMAGES);
int selectedPosition = intent.getIntExtra(SELECTED_IMG_ID, 0);
for (int i = 0; i < albumImgList.size(); i++) {
if (albumImgList.get(i).id == selectedPosition) {
// Objects.requireNonNull(allAlbumImgRv.getLayoutManager()).smoothScrollToPosition(allAlbumImgRv, null, i);
scrolledPosition = i;
break;
}
}
}
but when i pass the second intent it shows this error

there i was passing All album as parceable and in the two intent it has the same object
but one work and one generate strange error related to parcelable!!

You can trying this one :
#Parcel
-keepclassmembers class * implements android.os.Parcelable {
static ** CREATOR;
}
Add this to proguard , it can be help u.

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.

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.
