阅读更多关于 How to avoid writing duplicate boilerplate code for requesting permissions?

问题 I'm updating my app to be Android 6-compatible. The permission model is not very complex in theory, but now I'm in the process of implementing it and I find myself writing the same ugly boilerplate code in every one of my activities that require permissions. For every permission I need, there is a if (ActivityCompat.checkSelfPermission(this, Manifest.permission.PERMISSION) != PackageManager.PERMISSION_GRANTED) { } else { } and then in the onRequestPermissionsResult I have to check/filter the

问题 I want to check how new permission model works so in app's settings I disable Contacts .

Android DOZE mode GCM Priority

阅读更多关于 Android DOZE mode GCM Priority

For DOZE mode test, I am developing a sample GCM App on Android 6.0. As it's said, In DOZE mode the device would not wakeup for normal priority GCM. I wanted to check this. As per the documentation ( https://developers.google.com/cloud-messaging/concept-options#setting-the-priority-of-a-message ) Normal priority. This is the default priority for message delivery. Normal priority messages won't open network connections on a sleeping device, and their delivery may be delayed to conserve battery. For less time-sensitive messages, such as notifications of new email or other data to sync, choose

I've followed this stackoverflow post to set my Nexus 5 device to the 'IDLE' state with adb, after switching off the screen. > adb shell dumpsys battery unplug > adb shell dumpsys deviceidle step Stepped to: IDLE Despite this, I am able to see through my device logs the GCM notifications being received. 1-04 15:21:40.708 22138 26007 I GCM : GCM message com.sample.app 0:1446610899548646%82d6ec5bf9fd7ecd My understanding is that Doze mode will allow for certain maintenance windows where normal priority notifications are pushed in a batch, so I was not expecting to see such log entry.

Android sensor sampling rate won't drow below 60 hz

阅读更多关于 Android sensor sampling rate won't drow below 60 hz

问题 I'm reading out the accelerometer sensor on a Sony Smartwatch 3. Since the Android Wear 1.5 update the sampling rate won't drop below about 60hz, regardless weather I use SENSOR_DELAY_NORMAL , SENSOR_DELAY_UI or SENSOR_DELAY_GAME . Before the update SENSOR_DELAY_NORMAL resulted in a sampling rate of about 18 samples/seconds. accelerometer.getMaxDelay() still returns 62500, which would be 16 samples/sec. I also tried setting the desired delay directly, when registering the sensor with
