I have tried the below code. However, it always results the 160*160 dimension image.

try {   
    //call the standard crop action intent (the user device ma         


        

Answer 1

I have solved this by create a new file before calling Intent and passing this file path to store the cropped image through intent. Here is the solution for this.

private Uri mCropImagedUri;
private final int CROP_IMAGE = 100;//unique request code number. Which is used to identify the request result in onActivityResult()
/**Crop the image
 * @return returns <tt>true</tt> if crop supports by the device,otherwise false*/
private boolean performCropImage(){
    try {
        if(mFinalImageUri!=null){
            //call the standard crop action intent (the user device may not support it)
            Intent cropIntent = new Intent("com.android.camera.action.CROP");
            //indicate image type and Uri
            cropIntent.setDataAndType(mFinalImageUri, "image/*");
            //set crop properties
            cropIntent.putExtra("crop", "true");
            //indicate aspect of desired crop
            cropIntent.putExtra("aspectX", 1);
            cropIntent.putExtra("aspectY", 1);
            cropIntent.putExtra("scale", true);
            //indicate output X and Y
            cropIntent.putExtra("outputX", 500);
            cropIntent.putExtra("outputY", 500);
            //retrieve data on return
            cropIntent.putExtra("return-data", false);

            File f = createNewFile("CROP_");
            try {
                f.createNewFile();
            } catch (IOException ex) {
                VLLog.e("io", ex.getMessage());  
            }

            mCropImagedUri = Uri.fromFile(f);
            cropIntent.putExtra(MediaStore.EXTRA_OUTPUT, mCropImagedUri);
            //start the activity - we handle returning in onActivityResult
            startActivityForResult(cropIntent, CROP_IMAGE);
            return true;
        }
    }
    catch(ActivityNotFoundException anfe){
        //display an error message
        String errorMessage = "Whoops - your device doesn't support the crop action!";
        Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
        toast.show();
        return false;
    }
    return false;
}

private File createNewFile(String prefix){
    if(prefix==null || "".equalsIgnoreCase(prefix)){
        prefix="IMG_";
    }
    File newDirectory = new File(Environment.getExternalStorageDirectory()+"/mypics/");
    if(!newDirectory.exists()){
        if(newDirectory.mkdir()){
            VLLog.d(mContext.getClass().getName(), newDirectory.getAbsolutePath()+" directory created");
        }
    }
    File file = new File(newDirectory,(prefix+System.currentTimeMillis()+".jpg"));
    if(file.exists()){
        //this wont be executed
        file.delete();
        try {
            file.createNewFile();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    return file;
}

So here we should not bother about the data which comes in onActivityResult() method.

Android doesn't support a cropping intent built in. You should not assume it's available.

Instead you should use your own solution, or use a third party library, like this one:

Answer 3

In this way,you can scale the image:

Bitmap.createScaledBitmap(bitmap,50,50,true);
