How Can the Settings App Start an App's Non-Exported Activity?

阅读更多关于 How Can the Settings App Start an App's Non-Exported Activity?

Android N lets you link an activity of yours into your app's page in Settings. Just add an <intent-filter> for android.intent.action.APPLICATION_PREFERENCES . Android N's Settings app will look for the activity in your app that has that <intent-filter> . If Settings finds one, it will add a gear icon to your app's page in Settings, and if the user taps the gear, they will be taken to your designated activity.

阅读更多关于 What kind of Android application will require android.permission.READ_PHONE_STATE permission?

I have seen some Android apps on my phone require this android.permission.READ_PHONE_STATE permission. I don't know if I could trust them.

阅读更多关于 Android: get user ID without requiring scary (for user) permissions?

That all works fine, but some users are (understandably) scared off by any permission that seems to give the app some evil power to trawl through their account info or contacts. EDIT: this issue is even more acute

What's the use case where I need the coarse location? 回答1: Do I also need the ACCESS

问题 I think I've tried all the solutions I found on the internet, but no one worked - no force close, but nothing appears on desktop.
