Thank you Randy Tong I will look into ConstraintLayout

<?xml version="1.0" encoding="utf-8"?> <resources xmlns:tools="http://schemas.android.com/tools"> <dimen name="design_navigation_icon_size" tools:override = "true" >30dp</dimen>    // cornor radius for all button    <dimen name="cornerRadiusForButtons">5dp</dimen>    // cornor radius for all edit texts and text views and card views    <dimen name="cornerRadiusForEdittexts">5dp</dimen>    // elevation for cardView    <dimen name="elevation">15dp</dimen>    // this is the heading text size heading of all activities    <dimen name="textSize">35sp</dimen>    // used only once in userprofile below circleimageview    <dimen name="belowHeadingSize">23sp</dimen>    // this is the text that is present in the activity    <dimen name="endSize">17sp</dimen>    // button heights    <dimen name="buttonHeight">50dp</dimen>    // this is button text size    <dimen name="buttonTextSizeMain">25sp</dimen>    // donot know where does this use    <dimen name="buttonTextSize">30sp</dimen>    // width size of text view and edit texts    <dimen name="widthEditText">290dp</dimen>    // toolbar main title    <dimen name="toolbarTitle">18sp</dimen>    // toolbar subtitle    <dimen name="toolbarSubtitle">14sp</dimen>    // custom upper and lower cornors of the alert diloge etc    <dimen name="customUpperLowerCorners">5dp</dimen> </resources>

I have an issue using scroll view below are the cases

**CASE 1**

when i don't use scrollview i get the layout like [this][1] and this is the layout i need.
Problem with this approach is when the device resolution is low 412 x 732 or below i cant see the whole content of the layout for that reason **i need scrollview**

**CASE 2**

if i use scroll view i get the view like this [this][2] and [this][3] this which is perfect and what i need for 412 x 732 or below but the problem occur when i see the layout in higher resolution 1080x1920 i get [this][4]

what is need is in **CASE 2** for higher resolution device the PROCEED button should touch the bottom with bottomPadding=20dp just like **CASE 1** image

I Really appreciate if someone give me suggestion to acquire the layout that work for both the devices having high and low resolution

in layout i removed the scrollview and i get the layout that is good for high resolution device but with the low resolution i do not get the whole content to see because i need to scroll down

Thanks for clarification

I have 2 questions

Question1 :

I have a file which is named as 3242349d9id.jpg and I want to convert the file name as saadzahoor.jpg
I really appreciate if someone helps me how can I edit the filename

String fileName = "3242349d9id.jpg ;

Question2 :

If I make an app for someone and the app itself is not generating any money, I mean he or client cannot generate any money from the app it is just for the business purpose to see the activity of his (my client) clients!! Will the app considered for commercial use?
As a developer, i am getting paid for developing the app.

Will the app get the tag as commercial use?

Thanks for the reply

I am capturing the view of the scroll view and create the bimap object and then saving the image into the device

while doing so i am facing error

Caused by: java.lang.IllegalArgumentException: width and height must be > 0

can anyone fix the issue ! what i am doing wrong

private void print(){        ProgressDialog dialog = new ProgressDialog(getActivity());        dialog.setMessage("Saving...");        dialog.show();        Bitmap bitmap = getBitmapFromView(native_resit,native_resit.getChildAt(0).getHeight(),native_resit.getChildAt(0).getWidth());        try {            File defaultFile = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/Your_Folder");            if (!defaultFile.exists())                defaultFile.mkdirs();            String filename = "Order ID "+orderHistoryResponse.getOrderId()+".jpg";            File file = new File(defaultFile,filename);            if (file.exists()) {                file.delete();                file = new File(defaultFile,filename);            }            FileOutputStream output = new FileOutputStream(file);            bitmap.compress(Bitmap.CompressFormat.PNG, 100, output);            output.flush();            output.close();            dialog.dismiss();            Toast.makeText(getActivity(), Message.RECEIPT_SAVE, Toast.LENGTH_SHORT).show();        } catch (Exception e) {            e.printStackTrace();            dialog.dismiss();            Toast.makeText(getActivity(), Message.RECEIPT_SAVE_FAILED, Toast.LENGTH_SHORT).show();        }    }

Hey guyz .. i wanna ask can i install munt over kali ?

O i understand. We cannot just invoke the non static method into static method directly .. First we have to create the object then we can declare it ..

where as there is no need to create the object while calling the static method into static method

well thanks for the help

so is it wise while coding in android or when developing android app ... When ever i declare variable .. should i declare it static ? or same with the method ..

Since we cannot create use non-static into static but what when we instantiate the class in static method , the class is not static then why our code is still working ??

this is my code and i get no error . When i press the button i hear nothing

image link

i think its not reading the sound file .. its mp3 format

       makeSomeNoice.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View view) {                SoundPool soundPool ;                SoundPool.Builder soundBuilder ;                AudioAttributes audioAttribute ;                AudioAttributes.Builder audioBuilder ;                int id_for_sound ;                audioBuilder = new AudioAttributes.Builder();                audioBuilder.setUsage(AudioAttributes.USAGE_GAME);                audioBuilder.setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION);                audioAttribute = audioBuilder.build() ;                soundBuilder = new SoundPool.Builder() ;                soundBuilder.setAudioAttributes(audioAttribute);                soundPool = soundBuilder.build() ;                id_for_sound = soundPool.load(Main_Activity.this , R.raw.coin_sound , 1);                soundPool.play(id_for_sound , 1 , 1, 0 ,0 ,1);                                            }        });

I dont know whats wrong my app craches every time ...
