在实现这个功能的时候,被不同的浏览器折磨的胃疼,最后实现了勉强能用,也查考了一下其他人的博客
android实现通过浏览器点击链接打开本地应用(APP)并拿到浏览器传递的数据
android/iPhone:如何从browser直接打开应用程序或者打开应用商店(如果没有应用程序)
1、Html页面(JS不在行,这个是其他人写的)
需要留意的是Android_URL,格式需要符合[scheme]://[host]/[path]?[query]
scheme:判别启动的App。
host:适当记述
path:传值时必须的key (没有也可以)
query:获取值的Key和Value (没有也可以)

Android_URL = "myapp://www.test.com/openwith?uid=123"; |

<!-- 默认入口 --> < activity android:name = "net.laobanquan.im.splash.StartActivity" android:launchMode = "singleTop" android:screenOrientation = "portrait" android:theme = "@android:style/Theme.Black.NoTitleBar" > < intent-filter > < action android:name = "android.intent.action.MAIN" /> < category android:name = "android.intent.category.LAUNCHER" /> </ intent-filter > </ activity > <!-- 新建入口 --> < activity android:name = "net.test.WebStartActivity" android:screenOrientation = "portrait" > < intent-filter > < action android:name = "android.intent.action.VIEW" ></ action > < category android:name = "android.intent.category.DEFAULT" ></ category > < category android:name = "android.intent.category.BROWSABLE" ></ category > < data android:scheme = "myapp" android:host = "www.test.com" android:path = "/openwith" /> </ intent-filter > </ activity > |
3、Activity入口接受参数

String action = getIntent().getAction(); String uid = null ; if (Intent.ACTION_VIEW.equals(action)){ Uri uri = getIntent().getData(); if (uri != null ){ uid = uri.getQueryParameter( "uid" ); } } Log.d(TAG, uid); |
4、总结
如果原来点击图片的默认入口是StartActivity,那么最好新建WebStartActivity入口,除了多做“接受参数”其他和StartActivity一样
