}Declare the CropImageActivity in the main project's AndroidManifest.xml
<activity android:name="com.jhuster.imagecropper.CropImageActivity"/>Declare the write_external_storage permission in the main project's AndroidManifest.xml
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />Call these methods to run CropImage Activity
//1. Using the CropIntent to help build the start intent
private void startCropImage() {
// Create a CropIntent
CropIntent intent = new CropIntent();
// Set the source image filepath/URL and output filepath/URL (Optional)
//intent.setImagePath("/sdcard/source.jpg");
intent.setOutputPath("/sdcard/cropped.jpg");
// Set a fixed crop window size (Optional)
//intent.setOutputSize(640,480);
// set the max crop window size (Optional)
//intent.setMaxOutputSize(800,600);
// Set a fixed crop window's width/height aspect (Optional)
//intent.setAspect(3,2);
// start ImageCropper activity with certain request code and listen for result
startActivityForResult(intent.getIntent(this), 0);
}Waiting for result
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode != RESULT_OK) {
return;
}
if (requestCode == 0) {
Uri croppedUri = data.getExtras().getParcelable(MediaStore.EXTRA_OUTPUT);
InputStream in = null;
try {
in = getContentResolver().openInputStream(croppedUri);
Bitmap b = BitmapFactory.decodeStream(in);
//mImageView.setImageBitmap(b);
}
catch (FileNotFoundException e) {
e.printStackTrace();
}
}
super.onActivityResult(requestCode, resultCode, data);
