Android Create View Crash

I'm trying to add Layout with this code:
LayoutInflater layoutInflater = (LayoutInflater) activity.getSystemService(LAYOUT_INFLATER_SERVICE);
mYouTubePlayerLayout = (ConstraintLayoutKeyDispatchWrapper) layoutInflater.inflate(R.layout.background_player_layout, null, false);
mYouTubePlayerLayout.setOnDispatchKeyEventListener(this);
mWindowManager = (WindowManager) activity.getSystemService(WINDOW_SERVICE);
createWindowParams(true);
mWindowManager.addView(mYouTubePlayerLayout, mWindowParams);
I understand that I need to get permissions from the user for 23 version and above, so I'm asking the user for the permission with this code:
if (Build.VERSION.SDK_INT >= 23 && !Settings.canDrawOverlays(this)) {
isAppPlayStorePermission = true;
AlertDialog.Builder dialog = new AlertDialog.Builder(activity);
dialog.setCancelable(false);
dialog.setIcon(R.drawable.ic_launcher);
dialog.setTitle(R.string.dialog_need_playstore_permissions_title);
dialog.setMessage(R.string.dialog_need_playstore_permissions_description);
dialog.setPositiveButton(R.string.button_exit, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
AndroidUtils.exitApp(activity);
}
});
dialog.setNegativeButton(R.string.button_settings, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION, Uri.parse("package:" + getPackageName()));
startActivityForResult(intent, 0);
}
});
dialog.show();
}
but now I'm getting a crash from Fabric:
Fatal Exception: java.lang.RuntimeException
Unable to create service ***: android.view.WindowManager$BadTokenException: Unable to add window android.view.ViewRootImpl$W#c7450fc -- permission denied for this window type
The crash is only for users with Android OS of 7 and below.
Any idea what is the problem?

No Activity found to handle Intent { act=android.settings.LOCALE_SETTINGS }

I am creating a code that checks for the current location, however, when I check for the current location, it crashes. I looked into Stack Trace and saw this. I read other forums but I am not familiar with their solutions. I am also a beginner in Java. I used an Amazon Fire Tablet to download this app. When I tried testing it on the emulator, the app did not crash.

Below is the code where it happened.
private void onGPS() {
final AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Enable GPS").setCancelable(false).setPositiveButton("YES", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
startActivity(new Intent(Settings.ACTION_LOCALE_SETTINGS));
}
}).setNegativeButton("No", new DialogInterface.OnClickListener() {
#Override

dialog.cancel();
}
});
final AlertDialog alertDialog = builder.create();
alertDialog.show();
}

Always use this method to start intents other than your app's -
Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
if(intent.resolveActivity(context.getPackageManager()) != null){
startActivity(intent);
}else{
//handle activity not found
}
this way you won't get ActivityNotFoundException.
You can also use try catch as -
try {
startActivity(new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS));
} catch (e: ActivityNotFoundException) {
//handle activity not found
}

I suppose you want to navigate to GPS settings screen.
try this.
startActivity(new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS));
The phone/device might be missing locale settings screen altogether which leads to the crash.

Intent i = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); //This line solve my issue
startActivity(viewIntent);

App crashes when Progress Dialog is open and user changes orientation [duplicate]

This question already has answers here:
What is a NullPointerException, and how do I fix it?
(12 answers)
Closed 5 years ago.
My application has a Progress Dialog for login process and when the orientation is changed while dialog box is open, app crashes.This all works fine, except when screen orientation changes while the dialog is up. At this point the app crashes. I am figuring out this issue from the last 3 nights but not able to get it, please help.

Add this configuration change in your Android manifest activity:
<activity
android:name="YourActivity"
android:configChanges="orientation|keyboardHidden|screenSize"/>

error dialog.show(); Alert dialog

I have an AlertDialog it works fine but I noticed that it marks me an error in the line where I put dialog.show (); I do not know how I could solve it.
IngresarAdmin.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final AlertDialog.Builder mBuilder=new AlertDialog.Builder(InicioSesion_Principal.this);
View Mview= getLayoutInflater().inflate(R.layout.zona_restrigida,null);
final EditText claveAdmin=(EditText)Mview.findViewById(R.id.Clave_proveedor);
Button EntrarClaveAdmin=(Button)Mview.findViewById(R.id.Ingresar_clave_proovedor);
EntrarClaveAdmin.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (!claveAdmin.getText().toString().isEmpty()){
Intent intent=new Intent(getApplicationContext(), menu_administrador.class);
startActivity(intent);
overridePendingTransition(R.anim.fade_in, R.anim.fade_out);
finish();
}
else {
Toast.makeText(InicioSesion_Principal.this,"Clave incorrecta",Toast.LENGTH_SHORT).show();
}
}
});
mBuilder.setView(Mview);
AlertDialog dialog=mBuilder.create();
dialog.show();
}
});
This is the error that shows me in the dialog.show();
It does not close the application at any time, but how can I fix it?

try using dialog.create().show();
I had the same problem.

You need to call .dismiss();
if(dialog != null)
dialog.dismiss();

Android App crashes on Lollipop

hi I am using google license checker on my app it works on API 19 and below but crashes on lollipop. I saw the code that has to be add to my license check code but I don't know where to put this code or what should I edit. here is my code

and here is the other code which I got that this can solve my problem. but don't know where to put it.
Intent serviceIntent = new Intent(
new String(Base64.decode("Y29tLmFuZHJvaWQudmVuZGluZy5saWNlbnNpbmcuSUxpY2Vuc2luZ1NlcnZpY2U=")));
serviceIntent.setPackage("com.android.vending");
boolean bindResult = mContext
.bindService(
serviceIntent,
this, // ServiceConnection.
Context.BIND_AUTO_CREATE);

Waiting for an official solution, the current solution consists in patching Google's LicenseChecker class
com.google.android.vending.licensing.LicenseChecker.checkAccess(LicenseChecker.java:150)
like this:
new String(
- Base64.decode("Y29tLmFuZHJvaWQudmVuZGluZy5saWNlbnNpbmcuSUxpY2Vuc2luZ1NlcnZpY2U="))),
+ Base64.decode("Y29tLmFuZHJvaWQudmVuZGluZy5saWNlbnNpbmcuSUxpY2Vuc2luZ1NlcnZpY2U=")))
+ .setPackage("com.android.vending"), // this fix the 'IllegalArgumentException: Service Intent must be explicit'
this, // ServiceConnection.
Adding package name with statement setPackage("com.android.vending") makes the Intent explicit, i.e., 'safe' (as requested by Android Lollipop )
Note:
Please pay attention as after modifying LicenseChecker class you must change the min sdk version from 3 to 4 (thanks russellhoff)
