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:
12/02 12:19:56: Launching 'app' on Pixel_3a_API_30_x86.

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!

it says "You need to use a Theme.AppCompat theme (or descendant) with this activity."
maybe you edited/removed the theme by mistake. check your manifest
have you declared this activity in your AndroidManifest.xml? check this one Check your manifest first and declare your activity
Add or modify existing theme with AppCompat theme in your styles.xml. like the following:
<style name="yourThemeName" parent="#style/Theme.AppCompat....">
//.... items will go here
</style>
And you can use this theme as global theme
<application
android:theme="#style/yourThemeName">
OR
For specific activity
<activity
android:name=".ErangleMap"
android:theme="#style/yourThemeName">
//....
</activity>
I'm creating an Android input method, and want to use TabLayout from the support library in the InputView (the UI where the user inputs text in the form of keyclicks).
The layout for the InputView is very simple:
<?xml version="1.0" encoding="utf-8"?>
<org.szm.enigma2.ime.InputView xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.TabLayout android:id="#+id/tab"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_alignParentTop="true"
style="#style/Theme.AppCompat">
<android.support.design.widget.TabItem android:text="Hello"/>
<android.support.design.widget.TabItem android:text="World"/>
<android.support.design.widget.TabItem android:text="Enigma"/>
</android.support.design.widget.TabLayout>
</org.szm.enigma2.ime.InputView>
And I use the same layout for both InputView and the settings activity, which is a normal activity.
Create InputView from subclass of InputMethodService:
return getLayoutInflator().inflat(R.layout.input_view, null);
Inside the constructor of settings activity class:
setContentView(R.layout.input_view);
When I run the program, the settings activity is normal. Then tab layout is working perfectly. But when I activate the input method's input view, the program crashes with the following info:

I don't know why it didn't work even if I set the style attribute. And how can I use tab layout in an input view? (since input view is not inside any activity)
Thanks
EDIT
I have already checked this question and googled other resources. Most of them is dealing with error of inflating TabLayout in Activity. My problem is that TabLayout works fine inside Activity but not in input view.
you can do it like this:
Context context = new ContextThemeWrapper(this, android.support.v7.appcompat.R.style.Theme_AppCompat_Light_NoActionBar);
LayoutInflater inflater = LayoutInflater.from(context);
view = (View) inflater.inflate(R.layout.XXXXX, null);
the Tablayout is in the R.layout.XXXXX
I am totally new with android, i created an app with basic activity and then added a button to direct to another activity, it worked but whenever i click the button to go to the new activity page the app get crashed

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
Here's a problem that's really getting to me, whenever I try to launch my application's main activity, I get the error in LogCat:
java.lang.RuntimeException: Unable to start activity ComponentInfo{me.kworden.atic/me.kworden.atic.MainActivity}: android.content.res.Resources$NotFoundException: Resource ID #0x7f0c00a9
The stack trace says that the problem is my super.onCreate(savedInstanceState) in my onCreate() method, which is frustrating me, because I can't control the superclass method.
The content layout I'm using is only a LinearLayout, so I don't think it is necessary for you all to see my xml file, although I will post on request.
I've seen the other similar problems on SO, but the only answers were "Clean/Rebuild the project" which hasn't done anything for me. I'm using Android Studio ver. 1.1.0 if this is a known problem, but I haven't seen any known bugs.
Here is my MainActivity, I've stripped out most of the code in order to pinpoint the problem, but now it seems that super.onCreate is the culprit; despite being extremely barebones, my app still fails to even start (i.e. I get "Unfortunately, app has stopped.").
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
public class MainActivity extends ActionBarActivity
{
#Override
protected void onCreate(Bundle savedInstanceState)
{
// Create the activity and set the main content view //
super.onCreate(savedInstanceState); // This is line 17, per the stack trace //
setContentView(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
// Inflate the main menu to the toolbar //
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
int id = item.getItemId();
if(id == R.id.action_settings)
{
return true;
}
return super.onOptionsItemSelected(item);
}
}

If anyone stumbles on this in the future I want to make sure that you can get an answer...
The problem was that certain tags that are available only to Material and Android 5.0+ were being used in my styles. So I instead made a res/values-v21/styles.xml folder and put my appropriate settings in there. That fixed the issue.
Remove setContentView(R.layout.activity_main); method
after removing this method if it run successfully then your layout id cannot be gernerated.
and also make sure that your layout id is generated or not in R.java file
open manifest file check application package and activity. that is included or not included in file and also check style of application
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="yourapplicationpackage" >
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"

android:theme="#style/AppTheme"

<activity

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
If you using tag <view> on xml file just change tag <view> to <View>
I'm facing a strange issue when declaring a Content Provider in my project. I'm copying the classes and Manifest declaration from another project of my own. It's working OK on my other project.
Here's part of my Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.qr"
android:installLocation="auto"
android:versionCode="540"
android:versionName="5.4" >
(...)
<application
android:name=".Application"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:logo="#drawable/ic_launch" >
(...)
<provider
android:name=".provider.HistoryProvider"
android:authorities="com.example.qr.History"
android:exported="true"
android:multiprocess="true"
android:readPermission="com.example.qr.History.read"
android:writePermission="com.example.qr.History.write" />
(...)
</application>
</manifest>
When I run my app, I get this stack trace:
FATAL EXCEPTION: main

This is the whole stack trace. No 'com.example' trace is included. Of course some code in my app is producing this but the actual crash happens in Android.
Because my own classes are not included in the stack trace, I really don't know where to look.
I've run the code in an emulator with Android 4.2 and I've compared it with the source code of that version of Android, so I know the crash is produced in this line of ActivityThread:
4782 ApplicationInfo ai = info.applicationInfo;
4783 if (context.getPackageName().equals(ai.packageName)) {
Here's a link to the source code of this class.
If I don't declare the content provider (i.e. if I remove from my Manifest), the app works perfectly.
I've added some logs to my Application class, as well as the main Activity class. The crash is produced before either is launched.
So, my question is: what in my code can be producing context, context.getPackageName() or info.applicationInfo to be null during installation?
EDIT
When triggering the stack trace in the emulator several times, I only get this between traces:
