you can use chrome custom tabs read here.

what chrome custom tabs?

app developers face choice when user taps url either launch browser, or build own in-app browser using webviews.

both options present challenges — launching browser heavy context switch isn't customizable, while webviews don't share state browser , add maintenance overhead.

chrome custom tabs give apps more control on web experience, , make transitions between native , web content more seamless without having resort webview.

chrome custom tabs allow app customize how chrome looks , feels. app can change things like:

toolbar color

enter , exit animations

add custom actions chrome toolbar, overflow menu , bottom toolbar

add support :

dependencies { ... compile 'com.android.support:customtabs:23.3.0' }

example :

string url = ¨https://google.com/¨; customtabsintent.builder builder = new customtabsintent.builder(); customtabsintent customtabsintent = builder.build(); customtabsintent.launchurl(this, uri.parse(url));

update can turn html5 on webview turning following settings on:

 wv = (webview) findviewbyid(r.id.webview);  websettings ws = wv.getsettings();  ws.setjavascriptenabled(true);  ws.setallowfileaccess(true);  if (build.version.sdk_int>=build.version_codes.eclair) {  try {  log.d(tag, "enabling html5-features");  method m1 = websettings.class.getmethod("setdomstorageenabled", new class[]{boolean.type});   m1.invoke(ws, boolean.true); method m2 = websettings.class.getmethod("setdatabaseenabled", new class[]{boolean.type});  m2.invoke(ws, boolean.true);  method m3 = websettings.class.getmethod("setdatabasepath", new class[]{string.class});  m3.invoke(ws, "/data/data/" + getpackagename() + "/databases/");   method m4 = websettings.class.getmethod("setappcachemaxsize", new class[]{long.type});  m4.invoke(ws, 1024*1024*8);  method m5 = websettings.class.getmethod("setappcachepath", new class[]{string.class});  m5.invoke(ws, "/data/data/" + getpackagename() + "/cache/");  method m6 = websettings.class.getmethod("setappcacheenabled", new class[]{boolean.type});   m6.invoke(ws, boolean.true); log.d(tag, "enabled html5-features");  } catch (nosuchmethodexception e) {   log.e(tag, "reflection fail", e);  } catch (invocationtargetexception e) {  log.e(tag, "reflection fail", e);  } catch (illegalaccessexception e) {  log.e(tag, "reflection fail", e);  }  }
