Permission denied for Android Studio

I have a permission denied problem when I run the app in my android studio. Before that, I need to declare that my group mates can run the code and pop out the data but me, we all use the same code and version but I use a mac that they use the win system.
Below is the logcat info:

Could anyone give me some suggestions to solve the issue? Any help is appreciated.

I am not sure if this will work for everyone, but I solved my problem by changing the Emulator.
Previously, I used the Nexus 5X Q(API29), but now I switched to the Nexus 5X API33 and doing so solved my problem.
I also tried others with API33 and they work just fine.

ANDROID STUDIO builds succesfully but doesn't run

I've just built my first android app copying the code from this video: https://www.youtube.com/watch?v=gTy13ioTddg&t=594s
The app builds without problems but when I try to run it, it suddenly closes.
That's the message of the debugger:

I've been trying to solve this problem several days so I would be very thankful if someone can help me!

Have tried you changing your ConstraintLayout to use androidx instead of support
try changing the opening tag of activity_main.xml to be:
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
and corresponding closing tag to be
</androidx.constraintlayout.widget.ConstraintLayout>
and then sync your project while connected to the internet.

I think it has problem with ConstraintLayout, can you share your xml files, that way I can help you batter.

I experience this error from time to time and use to solve by doing the following:
First, check if you have ConstraintLayout implementation in your app Gradle config
Then make sure there is no Error(maybe a semantic one) in your layout XML file
If the error persists, consider adding those two files to your question description so that one can easily help
Good Luck!

Android app works on emulator, installs on phone, and crashes on device [duplicate]

This question already has answers here:

Unfortunately MyApp has stopped. How can I solve this?

Closed 2 years ago.
This is a weird and I'm not sure what I have done wrong. The app installs perfectly fine on my Samsung J7 but as soon as I move from the MainActivity to the ScheduleActivity it crashes. On the other hand my fiance who lives in the the Netherlands has a Huawei Mate 20 pro and she can use it fine. I've sent her many iterations and she just updates the app and uses it. I built this app with mvc architecture so there are no calls to the database or model. I'll include the layout, some images, and the java code. If I can add anything else please let me know. Thank you for your help solving this.
MainActvity:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button scheduleButton = findViewById(R.id.schedule_button);
scheduleButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(MainActivity.this, ScheduleActivity.class);
startActivity(intent);
}
});
}

How the main layout looks:
Also here is a visual on the apps structure:
All I am doing is moving from the main package to the ui package and accessing the ScheduleActvity which has this code:
public class ScheduleActivity extends AppCompatActivity implements View.OnClickListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_schedule);
Button mondayButton = findViewById(R.id.monday_button);
Button tuesdayButton = findViewById(R.id.tuesday_button);
Button wednesdayButton = findViewById(R.id.wednesday_button);
Button thursdayButton = findViewById(R.id.thursday_button);
Button fridayButton = findViewById(R.id.friday_button);
Button saturdayButton = findViewById(R.id.saturday_button);
Button sundayButton = findViewById(R.id.sunday_button);
mondayButton.setOnClickListener(this);
tuesdayButton.setOnClickListener(this);
wednesdayButton.setOnClickListener(this);
thursdayButton.setOnClickListener(this);
fridayButton.setOnClickListener(this);
saturdayButton.setOnClickListener(this);
sundayButton.setOnClickListener(this);
}
#Override
public void onClick(View view) {
switch (view.getId()){
case R.id.monday_button:
Intent monday_intent = new Intent(ScheduleActivity.this, MondayActivity.class);
startActivity(monday_intent);
break;
case R.id.tuesday_button:
Intent tuesday_intent = new Intent(ScheduleActivity.this, TuesdayActivity.class);
startActivity(tuesday_intent);
break;
case R.id.wednesday_button:
Intent wednesday_intent = new Intent(ScheduleActivity.this, WednesdayActivity.class);
startActivity(wednesday_intent);
break;
case R.id.thursday_button:
Intent thursday_intent = new Intent(ScheduleActivity.this, ThursdayActivity.class);
startActivity(thursday_intent);
break;
case R.id.friday_button:
Intent friday_intent = new Intent(ScheduleActivity.this, FridayActivity.class);
startActivity(friday_intent);
break;
case R.id.saturday_button:
Intent saturday_intent = new Intent(ScheduleActivity.this, SaturdayActivity.class);
startActivity(saturday_intent);
case R.id.sunday_button:
Intent sunday_intent = new Intent(ScheduleActivity.this, SundayActivity.class);
startActivity(sunday_intent);
}
}
This is the respective layout file activity_schedule which has these buttons:
<Button
android:id="#+id/thursday_button"
style="?android:attr/borderlessButtonStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="24dp"
android:layout_marginTop="8dp"
android:background="#drawable/button_state"
android:text="#string/thursday"
android:textColor="#drawable/button_text_color"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/monday_button" />
And looks like this (I so badly wish I could easily add a drop shadow to the image):
The buttons lead to a given day you want to know more about such as ThursdayActivity or MondayActvity (I'm still not sure on the ui but I'm getting closer):
All of the daysoftheweek activities look the same as this and this ThursdayActivity:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_thursday);
//groupsArrayList = new ArrayList<>(); --debug
DatabaseHandler db = new DatabaseHandler(ThursdayActivity.this);
/* Uncomment and insert the group data*/
db.thursdayAddGroup(new Groups("Thursday","Daily reflection|Just for Today","9:00 AM","10:00 AM"));
db.thursdayAddGroup(new Groups("Thursday","12 Step|Sponsorship","12:00 PM","1:00 PM"));
db.thursdayAddGroup(new Groups("Thursday","HVN (Hearing voices network)","1:15 PM","2:45 PM"));
db.thursdayAddGroup(new Groups("Thursday","WRAP","3:00 PM","4:00 PM"));
TextView thursdayGroupNameOne = findViewById(R.id.thursday_group_name_one);
TextView thursdayGroupStartTimeOne = findViewById(R.id.thursday_group_start_time_one);
TextView thursdayGroupEndTimeOne = findViewById(R.id.thursday_group_end_time_one);
/* Explicitly indexing the database objects */
List<Groups> groupsList = db.getAllThursdayGroups();
thursdayGroupNameOne.setText(groupsList.get(0).getGroupDay());
thursdayGroupStartTimeOne.setText(groupsList.get(0).getGroupStartTime()); thursdayGroupEndTimeOne.setText(groupsList.get(0).getGroupEndTime());
All daysoftheweek layouts have a cardview that contain the textviews to get and display the data from the database set in the given activity such as this actvity_thursday.xml:

I hope this isn't too much and I did remove all unnecessary code so as not to throw the whole thing at you. Thanks truly, Wes.

Android webview not loading for localhost server

I have created a node.js web application and running it on port 3000. I wanted an android app for the same and created a webview based android app.
While testing I was trying to give the localhost ip, the static server IP but the webview app is not loading in all of them.
Output:

If you're using a physical device to run, then,
make sure your website is running at 192.168.x.xxx:port
set the full url in your activity, such as,
webview.loadUrl("http://192.168.1.107:3000/");
add
android:usesCleartextTraffic="true"
in AndroidManifest.xml to fix 'cleartext not permitted' error caused for not using https
For emulator use 10.0.2.2 as stated in the previous answer and follow the 3rd step

Use this
webview.loadUrl("http://10.0.2.2:3000");
Instead of
webview.loadUrl("127.0.0.1:3000");

Declare the second Activity in your manifest file and you should be sorted out
Also your button is not declared

Add this line inside <application> tag
<activity android:name=".registration" ></activity>
hope it helps
