问题 I am suffering from the problem of getting value 0.0 as latitude and longitude in Android Marshmallow (API 23) i.e. 6.0. I have searched a lot regarding this but didn't find solution of it. My code is fully working for the other API versions which are less than 23. I have also put the code for selfPermission and which all are working instead it's giving me 0.0 as late and long. Please have a look on the way I am following: GPSTracker.java public class GPSTracker extends Service implements

问题 Background Android had a lot of changes as to how to handle the SD-card and storage in general: API 3 - you get all access, no permission needed API 4-15 - you need to use WRITE_EXTERNAL_STORAGE, and you get all access. API 16-18 - if you wish only to read, use READ_EXTERNAL_STORAGE API 19-20 - you can't read or write to secondary external storage (SD-card), unless your app is a system app, or you have root. API 21-22 - in order to access the SD-card, you need to ask the user for permission,

问题 We are creating a timestamp application on Android and ideally this would use fingerprint to identify the user. In one organisation there can be like 150 different users. Would the fingerprint API allow multiple users? Or is this currently only for the owner of the device? If this is only for the current users, are there any other API's available that would allow this? If not I think we need to abandon this road completely. 回答1: Android M or Samsung or iPhone APIs only allow to verify current

问题 I am doing an application to scan barcodes on a button click and it was working fine up to Lollipop versions. When I came to Marshmallow it stopped working.

My question is how to allow camera permission to my app automatically in Marshmallow or by asking the user to turn on camera at runtime. A screen shot: 回答1: Below I have

问题 New runtime permissions in Android-M asking for minimum 23 API level, but I still need minimum 16 API level in my project. So, how to make this code more forward-compatible? Regards 回答1: Use ContextCompat.checkSelfPermission(), ActivityCompat.requestPermissions(), and ActivityCompat.shouldShowPermissionRequestRationale(), from the support-v4 library (v23 or higher). These are backwards-compatible; if you are running on an older version of Android, they will "do the right thing" (e.g., return

问题 I want to know the data usage history and noticed the "new" android-6 NetworkStatsManager which seems positive (I've used TrafficStats a while but that won't cover anything previous a reboot). From the API documentation: NOTE: This API requires the permission PACKAGE_USAGE_STATS, which is a system-level permission and will not be granted to third-party apps. However, declaring the permission implies intention to use the API and the user of the device can grant permission through the Settings
