android:text="Welcome"

</TextView>
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
this is because your < /TextView> was closed after fragment class so you got this error.
Also change here
startActivity(new Intent(LoginActivity.this,LoginSuccess.class).putExtra("usr",strUsername));
and also in your LoginSuccess Activity
Intent in = getIntent();
if (in.getStringExtra("usr") != null) {
final TextView setmsg = (TextView)findViewById(R.id.showmsg);
setmsg.setText("Welcome \n "+in.getStringExtra("usr"));
}
That means you have to declare this part in your manifest file...
<uses-feature android:glEsVersion="0x00020000" android:required="true/>
and must use latest updated Google Play Service.

Crash after splashscreen

i'm new at android studio and i'm developing my first app.
Everything worked fine until i implemented a splashscreen. Indeed, when i run the app, the splashcreen works, but then, it crashes.
The thing is that the splashscreen wasn't the first activity i've created (the main). I've created my app and when i finished it, i added a splashscreen.
Actually when i disable the splashscreen (the activity) and start directly with the previous "activity that appears on launch" (that is the "Menu"), it works fine.
And one weird thing: with the splashscreen enabled, it crashes only with certain devices. It runs perfectly with my Xiaomi Redmi Note 5 and a Galaxy S4 (or the nexus 5X emulator) but not with a Galaxy S3 and S6 .
I tried to replace the timer by a simple setonclicklistener button. But same, when it has to load the Menu, it crashes.
I haven't find similar problems on the forums so here i am !
The manifest:
<?xml version="1.0" encoding="utf-8"?>

Thanks by advance for helping me.

In your app gradle make sure that libs use the same version, like:
implementation 'com.android.support:design:28.0.0-alpha1'
implementation 'com.android.support:cardview-v7:28.0.0-alpha1'
implementation 'com.android.support:appcompat-v7:28.0.0-alpha1'
implementation 'com.android.support:gridlayout-v7:28.0.0-alpha1'
You probably don't need all of them.
Make the changes and then click "Sync Now"

Solved it:
I had to add this to the manifest:
android:largeHeap="true"
And it worked fine.

I have a button that sends the entered data to the database, After clicking on the button, an error appears unfortunately "project namе" has stopped, please, help!!!!

Android - App crashes immediately after launch (DevEnvironment: Eclipse, Emulator: BlueStacks, API: 17)

I am using eclipse for developing a game for android. The game is pretty much finished but it won't launch correctly on my emulator of choice (BlueStacks).
It only shows a white screen and the infobar for about 0.5 seconds before crashing. App is still open in background after crashing but can't do or display anything.
I can compile and install the application and the syntax is correct... I assume that my mistake is somewhere in the manifest.
here is my manifest

You are calling getResources while the activity is instantiating on this line here:
// RANDOM FACT
String[] factresource = getResources().getStringArray(R.array.factres);
and the implied Activity.this object does not have a valid context, so it crashes. You need to call this in onCreate or in another method that is called after the object instantiates.

Trying to code an android app through eclipse to register bluetooth proximity, crashing on startup

I am writing an app that will eventually use Bluetooth to get a value for two devices' proximity to one another. I am currently trying to use buttons and onClick/onclicklistener etc to bring switch screens from the main UI to a log in or sign up page. Now my app is forcing close on start up and I'm not sure why. Thanks for any help!!

Move this code inside your onCreate method:
if (bluetooth != null) {
if (bluetooth.isEnabled()) {
String mydeviceaddress = bluetooth.getAddress();
String mydevicename = bluetooth.getName();
status = mydevicename + ":" + mydeviceaddress;
} else {
status = "Bluetooth is not Enabled.";
}
//etc...
Currently this code block is outside of any method of your activity and that is for sure not what you want to have.

ActivityManager: Warning: Activity not started, its current task has been brought to the front. All the related answer I have read were not fruitful.

I have tried editing the code as it would re-install the application on the emulator but again I'm getting the same error again and again.
It's saying edit source lookup path and showing a button for it.

That was the main.xml file above.
package a.fr.read;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class FastreaderActivity extends Activity {
/** Called when the activity is first created. */
Button startReading,clearBox;
EditText textReader;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
startReading=(Button)findViewById(R.id.textReader);
clearBox=(Button)findViewById(R.id.textReader);
textReader=(EditText) findViewById(R.id.textReader);
clearBox.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
textReader.setText("");
}
});
startReading.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
}
});
}
}
And this is the java code.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="a.fr.read"
android:versionCode="1"

<application
android:icon="#drawable/icon"
android:label="#string/app_name" >

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
And that was Android manifest file.

First clean your project and refresh that project(In Eclipse- Project-clean)for refresh(go that projectName(ListVeiwdemo) and right click and refresh option will come.)
