How to Crop Image from Camera and Gallery in Android?
  • Difficulty Level : Hard
  • Last Updated : 19 Feb, 2021

In the previous article, we have discussed how to select an Image from Gallery in Android, but in this project, there is no crop functionality. Sometimes we take pictures on our phone and want to update them as our profile picture. But we need to need to remove the background. So in that case we can use the crop image feature to remove that background and then we can upload that image. A sample video is given below to get an idea about what we are going to do in this article. Note that we are going to implement this project using the Java language. 

Step by Step Implementation

Step 1: Create a New Project

To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio. Note that select Java as the programming language.

Step 2: Add dependency to the build.gradle(Module:app) file

Navigate to the Gradle Scripts > build.gradle(Module:app) and add the below dependency in the dependencies section.   



// This library is used for crop image feature

api ‘com.theartofdev.edmodo:android-image-cropper:2.8.+’

// This library is used for loading the  

// cropped image into ImageView.

implementation ‘com.squareup.picasso:picasso:2.5.2’

Step 3: Working with the AndroidManifest.xml file

Add below permission to the AndroidManifest.xml file.

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



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

<uses-permission android:name=”android.permission.CAMERA”/>

Add below lines inside the <application> tag.

<activity

 android:name=”com.theartofdev.edmodo.cropper.CropImageActivity”

 android:theme=”@style/Base.Theme.AppCompat” />

Below is the code for the complete AndroidManifest.xml file.

XML




<?xml version="1.0" encoding="utf-8"?>
    package="com.anni.cropimage">
  
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.CAMERA" />
  
    <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/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
  
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
  
        <activity
            android:name="com.theartofdev.edmodo.cropper.CropImageActivity"
            android:theme="@style/Base.Theme.AppCompat" />
  
    </application>
  
</manifest>

Step 3: Working with the activity_main.xml file

Navigate to the app > res > layout > activity_main.xml and add the below code to that file. Below is the code for the activity_main.xml file. 

XML




<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginBottom="100dp"
    android:gravity="center"
    android:orientation="vertical"
    tools:context=".MainActivity">
  
    <!--Here the selected cropped image will be shown-->
    <ImageView
        android:id="@+id/set_profile_image"
        android:layout_width="300dp"
        android:layout_height="300dp"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="40dp"
        android:src="@drawable/ic_image_black_24dp" />
      
    <!--Here we are clicking on this text to select
        an image from camera or gallery-->
    <TextView
        android:id="@+id/click"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Click Here to select an Image"
        android:textSize="22sp"
        android:textStyle="bold" />
  
</LinearLayout>

Step 4: Working with the MainActivity.java file

Go to the MainActivity.java file and refer to the following code. Below is the code for the MainActivity.java file. Comments are added inside the code to understand the code in more detail.

        builder.create().show();
    }
  
    // checking storage permissions
    private Boolean checkStoragePermission() {
        boolean result = ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) == (PackageManager.PERMISSION_GRANTED);

    }

            case CAMERA_REQUEST: {
                if (grantResults.length > 0) {
                    boolean camera_accepted = grantResults[0] == PackageManager.PERMISSION_GRANTED;
                    boolean writeStorageaccepted = grantResults[1] == PackageManager.PERMISSION_GRANTED;
                    if (camera_accepted && writeStorageaccepted) {
                        pickFromGallery();
                    } else {
                        Toast.makeText(this, "Please Enable Camera and Storage Permissions", Toast.LENGTH_LONG).show();
                    }
                }
            }
            break;
