final PopupWindow popupWindow = new PopupWindow(popupView, LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT, true);
popupWindow.showAtLocation(popupView, Gravity.CENTER, 0, 0);
Button btn_dismiss = (Button)popupView.findViewById(R.id.btn_dismiss);
btn_dismiss.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
popupWindow.dismiss();
}});
popupWindow.showAsDropDown(btn_about, 50, -30);
}
});
}
}
i need to get red of the blue title bar.

You can remove the title bar forever by calling:
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
before the setContentView(R.layout.x) in your activity class.
To make the app fullscreen, you can do:
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
Again, put the above code before the setContentView method.
And make sure, if you are doing this, you should extend your Activity class by Activity and not AppCompatActivity or any other class.

Problem solved.
Because i didn't continue using the popup window,
i create a new activity instead and make the button redirect from main menu to About activity

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:

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.

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
<?xml version="1.0" encoding="utf-8"?>

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.

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.

setContentView(R.layout.main);

clearBox.setOnClickListener(new View.OnClickListener() {

});
startReading.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {

}
}
And this is the java code.

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.)

Thank you..

Why do you override the setContentView method in your Creation class? Since you don't call it, it won't set the correct view.
You should call setContentView from onCreate, and as far as I know, there is no need to override setContentView.
Try this in Creation:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.creation);
}

to

android:layout_height="wrap_content"
android:layout_gravity="center"
android:gravity="center"
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.
