2) Manifest which is for your permission
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.nilesh.photoframe">
<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.PhotoFrame">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
Now main and last part
3) Java main file( brain of app(backend))
package com.nilesh.photoframe;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageButton;
import android.widget.ImageView;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
ImageButton prev, next;
ImageView pic;
TextView text;
int currimg =0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void prev(View v) {
String idX = "pic" + currimg;
int x = this.getResources().getIdentifier(idX,"id",getPackageName());
pic =findViewById(x);
pic.setAlpha(0f);
currimg = (7+currimg-1)%7;
