Unable to Start Activity... android.content.res.Resources$NotFoundException: Drawable com.app: drawable/abc_vector_test with resource ID #0x7f07005c

I´m trying to do an App that works with Firebase and authenticates with Google, Email and Facebook.
Is exactly in the phase of Facebook sync that I had this problem:

Just so U know, my Gradle has a folder that says 6.5, which I think is the versión of Gradle.
PS: I´m literally a starter, so I do not understand most of the things I´m doing and probably will do, so please, help me in the easiest way possible (hahahah)

Analyzing the Stack Trace clearly I can depict that, It's causing an Runtime Exception since there is exactly no Resource found named drawable/abc_vector_test in your drawable folder.
Since Android didn't found the resource it's raising an Resource Not Found Exception. Kindly create the drawable file and then try running the app once.
For more information read the documentation here

Unhandled exceptions from DropBox API in Android Studio

I am trying to implement DropBox in my android app following instructions as given here . (using gradle)
When I get to the line: FullAccount account = client.users().getCurrentAccount(); I recieve the error
Unhandled exceptions: com.dropbox.core.DbxApiException, com.dropbox.core.DbxException
from the getCurrentAccount() part.
I can follow the suggestion to 'surround with try/catch' but if I do this the app crashes upon loading.
Apologies in advance for my ignorance. I am learning as I go along.
UPDATE:
I have realised I do not have the throws DbxException in my code. Trying the place it after onCreate method gives the error
'onCreate(Bundle)' in 'com.example.MyApp.MainActivity' clashes with 'onCreate(Bundle)' in 'androidx.appcompat.app.AppCompatActivity'; overridden method does not throw 'com.dropbox.core.DbxApiException'

You may be getting this error because it is a network call and you need to implement some kind of callback. Looking at the Dropbox SDK you will need something like this:
new GetCurrentAccountTask(DropboxClientFactory.getClient(), new GetCurrentAccountTask.Callback() {
#Override
public void onComplete(FullAccount result) {
// handle logic
}
#Override
public void onError(Exception e) {
Log.e(getClass().getName(), "Failed to get account details.", e);
}
}).execute();

Provider org.glassfish.jersey.client.JerseyClientBuilder could not be instantiated

I have a Android project that implements the Jersey client. I am presented the an exception when I execute the line:
Client client = ClientBuilder.newClient();
Here are my gradle dependencies:
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'com.google.android.material:material:1.0.0'

testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test:runner:1.2.0'

}
I have a project configured in Eclipse that also uses the client, with the same imports as the Android project, that works just fine.

This page may help you more.
Import RESTEasy client with specific version number as of your resteasy.
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-client</artifactId>
<version>3.0.2.Final</version>
</dependency>
This will provide necessary classes to build client for sending RESTful requests.
If still you get any error then use following classes :
ResteasyClient client = new ResteasyClientBuilder().build();
ResteasyWebTarget target = client.target("http://localhost:8080/RESTEasyApplication/user-management/users");
Response response = target.request().get();
String value = response.readEntity(String.class);
System.out.println(value);
response.close();
It will solve the error.

Android java.lang.RuntimeException: Parcelable encountered ClassNotFoundException reading a Serializable object

I'm trying to send the Serializable object from one application to another.
My android application has a serializable class
public class MyClass implements Serializable
and I then put one instance of it to the intent
MyClass myObject = new MyClass();
intent.putExtra("payItem", myObject);
intent.setAction("com.mypackage.some.action");
when I call startActiviy
startActivity(intent);
I got app crash

Actually my phone has installed two applications with both register an activity
with the same action name
<activity
android:name="com.mypackage.MyActivity"
android:exported="true"
>
<intent-filter>
<action android:name="com.mypackage.some.action"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</activity>
I would expect a dialog shown to let me choose which activity should be started, but I just got the error above. If I uninstall one of the applications, no error occurs and it runs as expected.
My question is
Why the dialog is not shown
Is it the reason of the crash
What's the solution to avoid that error if the two applications are both installed

RecyclerView and CoordinatorLayout with id are crashing

When I started writing nested fragments I encountered an unexpected problem. When the application is killed by Android, e.g. when there is a small amount of free RAM, the application throws the following exception after resuming it.

This error occurs only if RecyclerView or CoordinatorLayout in tab fragment are assigned in xml android id.
In order to identify the error, I wrote an application in which I reproduced it.
https://github.com/RicomenPL/SampleBPE
How to reproduce it?
Enable "dont keep activies" in the development options on the smartphone or emulator
Turn on the SampleBPE application
Move to tabs left or right
Now you have to leave with the Home key
Enter again with the use of the recent apps key
Moving the tabs to the left or right will cause an error

The problem was solved when I downgrade my support libraries to version 26.1.0. This is a temporary solution, to avoid the problem. I hope that in version 28, this will be resolved.
