Android: Launch additional apps and pass parameters

Reprinted from: http://blog.csdn.net/iefreer/article/details/8812585

Sometimes you need to launch another app from one app, such as twitter/.

If you do not know the activity of the app, but know the package name, then you can use the following method:

[Java]View Plaincopy

1. Intent launchintent = Getpackagemanager (). Getlaunchintentforpackage ("com.package.address");
2. StartActivity (launchintent);

If there is a partnership between apps, you can get a manifest file for the Affiliate app (manifest), you can learn about package/activity from this file,
You can use the following method to launch the app-specific activity interface:

[Java]View Plaincopy < param name= "allowfullscreen" value= "false" >< param name= "wmode" value= "Transparent" >

1. Intent Intent = new Intent (Intent.action_main);
2. Intent.setcomponent (new ComponentName ("com.package.address","com.package.address.MainActivity"));
3. StartActivity (Intent);

If you want to pass parameters when you start the app, you can set it in intent (Intent):

[PHP]View Plaincopy

1. Intent.putextra ("Firstkeyname","Firstkeyvalue");
2. Intent.putextra ("Secondkeyname","Secondkeyvalue");
