android-6.0-marshmallow

问题 I am a developer of two alarm clock apps on Google Play. I am trying to get them to work with Android 6.0. However, Doze mode makes it so they do not ring. I put them on the white list, I put a foreground notification icon up, I'm not sure what else I can do - when in Doze mode, the the Alarm Manager alarms are still ignored. The Clock app (which is a Google Play rather than AOSP app), however, is different. When the alarm is enabled on the Clock app, "adb deviceidle step" will always read

问题 In Android Marshmallow, permissions should be requested at runtime when they are needed, instead of all at once when an app is installed. However, I can only seem to request permissions from an Activity, which is a problem since my app contains only Services. (Why is that, you might ask? The app has an Android Wear watch face bundled inside, and all the phone does is look up photos nearby to send to the watch - no Activity needed. But it does require location permissions.) So, is there any

问题 I have an app that uses external storage to store photographs. As required, in its manifest, the following permissions are requested <uses-permission android:name="android.permission.CAMERA" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> and it uses the following to retrieve the required directory File sdDir = Environment .getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES); SimpleDateFormat dateFormat = new SimpleDateFormat("MM-dd", Locale.US);

问题 According to this: http://developer.android.com/preview/features/runtime-permissions.html#coding an app can check for runtime permissions and request permissions if it hasn't been granted already. The following dialog will be displayed then: In case the user declines an important permission, imo an app should display an explanation why the permission is needed and what impact declining has. That dialog has two options: re-try again (permission is requested again) deny (app will work without

问题 I have Android M set up for my project and could build fine. However, When i launch the app, i see the following error and app doesn't launch: <06-23 11:53:24.833 32416 32416 W System.err: java.lang.RuntimeException: **Unable to create application xxxxx: java.lang.SecurityException: "gps" location provider requires ACCESS_FINE_LOCATION permission.** 06-23 11:53:24.833 32416 32416 W System.err: at android.app.ActivityThread.handleBindApplication(ActivityThread.java:4697) 06-23 11:53:24.833

问题 Since android 6.0, the sdcard path is no longer "/storage/sdcard1/", "/storage/sdcard-ext/" or something. The path depends on the phone instead. If I use Nexus 5x AVD, the path is "/storage/1D15-3A1B/". When I use Nexus 6p AVD, the path is "/storage/4679-1802/". So how can I dynamically write the sdcard path in program to locate the file in external sdcard? Thank you! 回答1: Have a look at getExternalFilesDirs() . 回答2: It seems that I found the solution. I'm using the access storage framework.

问题 I'm trying to export my DB to a CSV file. I have applied the appropriate permission to the AndroidManifest.xml . I'm just wondering why I can't write/create the file in my (actual device) Nexus 5X API level 23 where the same code works in my emulator Nexus 7 API level 22. Is the permission not enough? Here's the code: private void writeCsv() { File fileDir = new File(Environment.getExternalStoragePublicDirectory( Environment.DIRECTORY_DOWNLOADS).getAbsolutePath(), File.separator + "Example");

问题 Google introduced Doze and App Standby mode with Android 6.0 OS. Device will enter in Doze mode if device is unplugged and unused for some amount of time and if application stays inactive for some amount of time, that app goes in StandBy mode (Correct me if I am wrong). Can we (developer) know, device entered in Doze mode or application entered in StandBy mode? How? http://developer.android.com/training/monitoring-device-state/doze-standby.html#whitelisting-cases In this link, Google says

问题 I'm trying to guide my users to the battery optimizations activity and it seems to be working for most except for some Samsung phones with Android 6 where I get: Fatal Exception: android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.settings.IGNORE_BATTERY_OPTIMIZATION_SETTINGS } This is what I am using to launch it: Intent intent = new Intent("android.settings.IGNORE_BATTERY_OPTIMIZATION_SETTINGS"); startActivity(intent); Any idea what I should be
