android - Don't know why the app is crashing -
i have written code, keeps on crashing, don't know point onwards. here code:
public class mainactivity extends activity { int windowwidth; int screencenter; int x_cord, y_cord, x, y; int likes = 0; relativelayout parentview; float alphavalue = 0; private context m_context; @suppresswarnings("deprecation") @suppresslint("newapi") @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); requestwindowfeature(window.feature_no_title); setcontentview(r.layout.mainlayout); m_context = mainactivity.this; parentview = (relativelayout) findviewbyid(r.id.layoutview); windowwidth = getwindowmanager().getdefaultdisplay().getwidth(); screencenter = windowwidth / 2; int[] myimagelist = new int[] { r.drawable.cats, r.drawable.baby1, r.drawable.sachin, r.drawable.cats, r.drawable.puppy }; (int = 0; < 5; i++) { layoutinflater inflate = (layoutinflater) m_context .getsystemservice(context.layout_inflater_service); final view m_view = inflate.inflate(r.layout.custom_layout, null); imageview m_image = (imageview) m_view.findviewbyid(r.id.sp_image); linearlayout m_toplayout = (linearlayout) m_view.findviewbyid(r.id.sp_color); linearlayout m_bottomlayout = (linearlayout) m_view.findviewbyid(r.id.sp_linh); // final relativelayout myrelview = new relativelayout(this); m_view.setlayoutparams(new layoutparams((windowwidth - 80), 450)); m_view.setx(40); m_view.sety(40); m_view.settag(i); m_image.setbackgroundresource(myimagelist[i]); if (i == 0) { m_view.setrotation(-1); } else if (i == 1) { m_view.setrotation(-5); } else if (i == 2) { m_view.setrotation(3); } else if (i == 3) { m_view.setrotation(7); } else if (i == 4) { m_view.setrotation(-2); } else if (i == 5) { m_view.setrotation(5); } // add dynamically button on image. final button imagelike = new button(m_context); imagelike.setlayoutparams(new layoutparams(100, 50)); imagelike.setbackgrounddrawable(getresources().getdrawable(r.drawable.like)); imagelike.setx(20); imagelike.sety(-250); imagelike.setalpha(alphavalue); m_toplayout.addview(imagelike); // add dynamically dislike button on image. final button imagepass = new button(m_context); imagepass.setlayoutparams(new layoutparams(100, 50)); imagepass.setbackgrounddrawable(getresources().getdrawable(r.drawable.dislike)); imagepass.setx(260); imagepass.sety(-300); imagepass.setalpha(alphavalue); m_toplayout.addview(imagepass); // click listener on bottom layout open details of // image. m_bottomlayout.setonclicklistener(new onclicklistener() { @override public void onclick(view v) { startactivity(new intent(m_context, detailsactivity.class)); } }); // touch listener on image layout swipe image right or left. m_toplayout.setontouchlistener(new ontouchlistener() { @override public boolean ontouch(view v, motionevent event) { x_cord = (int) event.getrawx(); y_cord = (int) event.getrawy(); m_view.setx(x_cord - screencenter + 40); m_view.sety(y_cord - 150); switch (event.getaction()) { case motionevent.action_down: x = (int) event.getx(); y = (int) event.gety(); log.v("on touch", x + " " + y); break; case motionevent.action_move: x_cord = (int) event.getrawx(); // updated more // smoother animation. y_cord = (int) event.getrawy(); m_view.setx(x_cord - x); m_view.sety(y_cord - y); // m_view.sety(y_cord-y); // y_cord = (int) event.getrawy(); // m_view.setx(x_cord - screencenter + 40); // m_view.sety(y_cord - 150); if (x_cord >= screencenter) { m_view.setrotation((float) ((x_cord - screencenter) * (math.pi / 32))); if (x_cord > (screencenter + (screencenter / 2))) { imagelike.setalpha(1); if (x_cord > (windowwidth - (screencenter / 4))) { likes = 2; } else { likes = 0; } } else { likes = 0; imagelike.setalpha(0); } imagepass.setalpha(0); } else { // rotate m_view.setrotation((float) ((x_cord - screencenter) * (math.pi / 32))); if (x_cord < (screencenter / 2)) { imagepass.setalpha(1); if (x_cord < screencenter / 4) { likes = 1; } else { likes = 0; } } else { likes = 0; imagepass.setalpha(0); } imagelike.setalpha(0); } break; case motionevent.action_up: x_cord = (int) event.getrawx(); y_cord = (int) event.getrawy(); log.e("x point", "" + x_cord + " , y " + y_cord); imagepass.setalpha(0); imagelike.setalpha(0); if (likes == 0) { // log.e("event status", "nothing"); m_view.setx(40); m_view.sety(40); m_view.setrotation(0); } else if (likes == 1) { // log.e("event status", "passed"); parentview.removeview(m_view); } else if (likes == 2) { // log.e("event status", "liked"); parentview.removeview(m_view); } break; default: break; } return true; } }); parentview.addview(m_view); } } } here logcat

thankyou in advance
java.lang.nosuchmethoderror: android.view.view.setx
setx available api level 11, , run code older device or on emulator older sdk. should viewcompat class, port of methods. e.g.
viewcompat.setx(m_view, 40) not of them back-ported on version of android, @ least avoid nosuchmethoderrorexception. way check explicitly against sdk_int
if (android.os.build.version.sdk_int >= android.os.build.version_codes. honeycomb) { // run starting honeycomb }
