问题 Documentation states that if an Intent can be processed by multiple applications the user will be prompted with a dialog asking him to choose the application to complete the action. Is there any way to make user select multiple applications that will complete the action one by one? For example, if I want to share a message I'll be using ACTION_SEND with a specified MIME type and I'll be prompted with a list of applications that can share the message. Can I make a user choose multiple apps to

问题 Google Chrome wouldn't launch my app on Deep Link, however, the app gets launched if I run it from Firefox. I use "onkat://" just as an example as I just want to get the app launched first.

问题 I'm trying to build an app to receive shares from the StumbleUpon app. I can, at this point, receive the browser's "share url", but when sharing from StumbleUpon my app does not show up on the list. I'm thinking that I may not have registered the correct Intents in the manifest. Is there any way to find what that app is doing? Thanks. 回答1: You can get a bit of information about intents from logcat. When I shared in StumbleUpon I noticed this in the log: 12-08 19:01:18.915: I/ActivityManager

问题 I need to call activity with different launchMode according to my app state. In one case it should be singleInstance , in other - singleTask . I know how to set launchMode in AndroidManifest , but since it should be dynamic property I have to do it from code. I thought, that I can add some specific flag to intent, before starting activity, but I found only singleTop flag. So is any way to solve this issue?
