由 我与影子孤独终老i 提交于 2019-11-27 03:26:10
My app is currently using Maps by Google Play Services speficying: mMap.setMyLocationEnabled(true); I realize each time I am displaying the map in my app: the location is indicated on the map by a blue dot a location icon is displaying in the top bar if I go into Settings/Location of the phone, my app is reported as "High battery use" However, I can see there are apps that use Maps and still show the location blue dot, but the location icon doesn't appear in top bar and their battery usage is low. My app currently grants both permissions: android.permission.ACCESS_COARSE_LOCATION android

问题 I enabled the my-location layer of the Google Maps Android API v2, which adds the floating button to go to the user's current location. I need a way to detect a click on this button. Is this possible? 回答1: No, currently there is no way to get that information. There is a feature request raised for that and it is already Acknowledged by Google. Star it if you want a quicker fix: http://code.google.com/p/gmaps-api-issues/issues/detail?id=4789&q=apitype%3DAndroid2&colspec=ID%20Type%20Status

问题 I've been using Google Maps API v2 for a long time on Android 4.x versions without a problem.

Android Google Map API V2 Blank Screen

由 ╄→гoц情女王★ 提交于 2019-11-27 02:11:36
问题 Hi I recently followed Vogella's tutorial on Google Map API v2. The code is similar to his. But for some reason the map shows up blank and the logcat shows no error either. I also followed this video to get the SHA1 finger print then I put the API key inside the manifest file. I used the debug keystore C:\Users\UserName.android\debug.keystore which is also the default debug keystore located in Eclipse -> Windows -> Preference -> Android -> Build.

TileProvider method getTile - need to translate x and y to lat/long

由 跟風遠走 提交于 2019-11-27 01:22:02
问题 I’m porting an iOS app to Android, and using Google Maps Android API v2. The application needs to draw a heatmap overlay onto the map. So far, it looks like the best option is to use a TileOverlay and implement a custom TileProvider . In the method getTile , my method is given x, y, and zoom, and needs to return a bitmap in the form of a Tile . So far, so good.
