Let user crop image

Question

I am having a hard time in figuring out how to let the user crop the picture. I would like to give bitmap variable with loaded bitmap to crop the picture before setting it as wallpaper. But I'm failing to do so... Here is that i tried.

First version. = Works as expected BUT the returned image is in poor resolution. Changing the output to higher value doesn't help. As I saw in some post it is not recommended to use camera as not all devices support this.

Intent intent = new Intent("com.android.camera.action.CROP");  
String path = Images.Media.insertImage(context.getContentResolver(), loaded,null, null);
Uri uri = Uri.parse(path);              
intent.setData(uri);  
intent.putExtra("crop", "true");  
intent.putExtra("aspectX", 1);  
intent.putExtra("aspectY", 1);  
intent.putExtra("outputX", 300);  
intent.putExtra("outputY", 300);  
intent.putExtra("noFaceDetection", true);  
intent.putExtra("return-data", true);                                  
startActivityForResult(intent, 2);

Second. Load up image chooser, and crop afterwards. How can I configurate this to load crop directly on my image? Just like in version 1

Intent photoPickerIntent = new Intent(MediaStore.ACTION_PICK);
photoPickerIntent.setData(uri);
photoPickerIntent.putExtra("crop", "true");
photoPickerIntent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
photoPickerIntent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString());
startActivityForResult(photoPickerIntent, 2);

And onActivity result

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode != RESULT_OK) { return; }
    if(requestCode == 2) {
        Bundle extras = data.getExtras();  
        if(extras != null ) {  
            Bitmap photo = extras.getParcelable("data");  
            loaded = photo;
        }
        WallpaperManager myWallpaperManager = WallpaperManager.getInstance(getApplicationContext());

        try {
            myWallpaperManager.setBitmap(loaded);
        } catch (IOException e) {}
    }
}

I do not know whever these are the correct methods to make this done, but I hope somebody could point me in the right direction. Which, why, and how to use.

Update: I am still waiting for someone to point out how to do it correctly, answers below are working but returning images in poor resolution, so they are not an option to use

Answer 1

Ok Dear Here I put my Whole code of Crop Image In Android. This the Global variable.

    //This For Image Crop
        /**
         *  Uri for set image crop option .
         */
        private Uri mImageCaptureUri;
        /**
         *  int for set key and get key from result activity . 
         */
        public final int CROP_FROM_CAMERA = 0;

/**
     * Bitmap for apply Crop Operation Result.
     */
    private Bitmap _tempOpration;

    //This is Crop Method.

/**
     * Method for apply Crop .
     * @param filePath -  String path of file .
     */
    private void doCrop(String filePath){
        try{
            //New Flow
            mImageCaptureUri = Uri.fromFile(new File(filePath));

            final ArrayList<CropOption> cropOptions = new ArrayList<CropOption>();
            Intent intent = new Intent("com.android.camera.action.CROP");
            intent.setType("image/*");
            List<ResolveInfo> list = getPackageManager().queryIntentActivities( intent, 0 );

            int size = list.size();
            if (size == 0) 
            {           
                Toast.makeText(this, "Can not find image crop app", Toast.LENGTH_SHORT).show();
                return;
            }
            else 
            {
                intent.setData(mImageCaptureUri);
                intent.putExtra("outputX", 300);
                intent.putExtra("outputY", 300);
                intent.putExtra("aspectX", 1);
                intent.putExtra("aspectY", 1);
                intent.putExtra("scale", true);
                intent.putExtra("return-data", true);

                if (size == 1) 
                {
                    Intent i = new Intent(intent);
                    ResolveInfo res = list.get(0);
                    i.setComponent( new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
                    startActivityForResult(i, CROP_FROM_CAMERA);
                }

                else
                {
                    for (ResolveInfo res : list) 
                    {
                        final CropOption co = new CropOption();
                        co.title = getPackageManager().getApplicationLabel(res.activityInfo.applicationInfo);
                        co.icon = getPackageManager().getApplicationIcon(res.activityInfo.applicationInfo);
                        co.appIntent= new Intent(intent);
                        co.appIntent.setComponent( new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
                        cropOptions.add(co);
                    }

                    CropOptionAdapter adapter = new CropOptionAdapter(getApplicationContext(), cropOptions);
                    AlertDialog.Builder builder = new AlertDialog.Builder(this);
                    builder.setTitle("Choose Crop App");
                    builder.setAdapter( adapter, new DialogInterface.OnClickListener()
                    {
                        public void onClick( DialogInterface dialog, int item )
                        {
                            startActivityForResult( cropOptions.get(item).appIntent, CROP_FROM_CAMERA);
                        }
                    });

                    builder.setOnCancelListener( new DialogInterface.OnCancelListener() 
                    {
                        public void onCancel( DialogInterface dialog ) 
                        {
                            if (mImageCaptureUri != null ) 
                            {
                                getContentResolver().delete(mImageCaptureUri, null, null );
                                mImageCaptureUri = null;
                            }
                        }
                    } );
                    AlertDialog alert = builder.create();
                    alert.show();
                }
            }
        }
        catch (Exception ex) 
        {
            genHelper.showErrorLog("Error in Crop Function-->"+ex.toString());
        }
    }

This is the another Class witch use for find Crop Activity Intent in Application.

CropOption Class.

public class CropOption 
{
    public CharSequence title;
    public Drawable icon;
    public Intent appIntent;
}

this is use For Display List.

CropOptionAdapter

public class CropOptionAdapter extends ArrayAdapter<CropOption> 
{
    private ArrayList<CropOption> mOptions;
    private LayoutInflater mInflater;

    public CropOptionAdapter(Context context, ArrayList<CropOption> options) 
    {
        super(context, R.layout.crop_selector, options);

        mOptions    = options;

        mInflater   = LayoutInflater.from(context);
    }

    @Override
    public View getView(int position, View convertView, ViewGroup group)
    {
        if (convertView == null)
            convertView = mInflater.inflate(R.layout.crop_selector, null);

        CropOption item = mOptions.get(position);

        if (item != null) {
            ((ImageView) convertView.findViewById(R.id.iv_icon)).setImageDrawable(item.icon);
            ((TextView) convertView.findViewById(R.id.tv_name)).setText(item.title);

            return convertView;
        }

        return null;
    }
}

Layout File For CropOptionAdapter

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:padding="10dp"
    android:gravity="center_vertical">

    <ImageView
        android:id="@+id/iv_icon"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

    <TextView
        android:id="@+id/tv_name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text=""/>
</LinearLayout>

This is the resultActivity.witch give the crop image.

/**
     * @see android.app.Activity#onActivityResult(int, int, android.content.Intent)
     */
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) 
    {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode != RESULT_OK) return;
        switch (requestCode)
        {
        case CROP_FROM_CAMERA:
            if (data == null) 
            {
                genHelper.showToast("No Crop Activity in This");
                return;
            }
            final Bundle extras = data.getExtras();
            if (extras != null) 
            {
                try 
                {

                    _tempOpration=extras.getParcelable("data");
                    imageLayout.setImageBitmap(_tempOpration);
                    _tempOpration=null;

                } 
                catch (Exception e) 
                {
                    e.printStackTrace();
                }
            }
            break;
        }

    }

//Do This Type It's work on my live app.

genHelper.showToast("No Crop Activity in This");

is my general Class to help display toast message and Error Log.

Bestof Luck.
