Cannot use Android Crop image crop library in Android -
i developing android project. in project, want add crop image feature. used library, https://github.com/jdamcd/android-crop. when use it. giving me error. please see scenario below.
this how installed.
i put in grandle, compile 'com.soundcloud.android:android-crop:1.0.1@aar'
i put in manifest file,
this how using in code.
i open image picker this
crop.pickimage(currentactivity.this, image_chooser_request_coode);in onactivityresult, doing this
@override protected void onactivityresult(int requestcode, int resultcode, intent data) { super.onactivityresult(requestcode, resultcode, data); if(requestcode==image_chooser_request_coode && resultcode == result_ok) { crop.of(data.getdata(),null).assquare().start(createitemactivity.this); } else if(requestcode == crop.request_crop && resultcode == result_ok) { uri filepath = data.getdata(); } }but after crop image , click "ok", result of activity not equal ok. cannot retrieve cropped image data.
so removed resultcode==result_ok , retrieved this
if(requestcode == crop.request_crop) { uri filepath = data.getdata(); }
data null. please suggest wrong code , how can fix it? please me. correct way use it.
add in build.gradle file
repositories { mavencentral() } dependencies { compile 'com.edmodo:cropper:1.0.1' } make layout of image this
