Today we will learn how to create a pdf file and after creating a pdf file we will be able to print this pdf using a wifi printer.

First of all, we need to add dependency in the build.Gradle(:app)file.

implementation 'com.itextpdf:itextg:5.5.10'
implementation 'com.karumi:dexter:6.2.3'

Now we need to add uses permission and the provider in the manifest file.

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.androidpdfprint">

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/Theme.AndroidPDFPrint">
<activity
android:name=".MainActivity"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

<provider
android:authorities="com.example.androidpdfprint.fileprovider"
android:exported="false"
android:grantUriPermissions="true"
android:name="androidx.core.content.FileProvider">

<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths"/>
</provider>

</application>

</manifest>

In the res folder, we need to add an XML directory and after creating the XML directory create an XML file.

provider_path.xml

<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path
name="exteranl_files"
path="."/>

</paths>

Now we will design our UI part in the main activity.

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">

<Button
android:id="@+id/btn_create_pdf"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:fontFamily="@font/roboto"
android:text="Create PDF"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>

Now we will code for the MainActivity.

Thank you for reading.

Happy Coding!!.
