usage-statistics

I'm trying to get the mobile data used by all application in previous month( or week) or between a given time period. I want to get the mobile data usage history. I see that android is doing this by default now. Is it possible to get this information by code? Is it possible to get this information by code? Not in any documented or supported fashion, at least through Android 4.4. You are welcome to collect this data yourself by periodically examining TrafficStats , though. Try this code public void getPakagesInfoUsingHashMap() { final PackageManager pm = getPackageManager(); // get a list of

Firstly, I'm not looking for time spent on a given application. There is already "an app for that", com.android.settings/.UsageStats , and a good deal of supporting code in the AOSP frameworks/base/services/java/com/android/server/am/UsageStatsService.java , etc. The code that I've examined so far does not seem to record elapsed time spent on particular <activity> s . I have thought to get this information two ways, but feel there must be something cleaner and simpler, that leverages more existing code. The ideas have been: Instrument the base Activity class onPause() and onResume() , to hack

Using this code, I can find the battery level of the phone: int level = battery.getIntExtra(BatteryManager.EXTRA_LEVEL, -1); int scale = battery.getIntExtra(BatteryManager.EXTRA_SCALE, -1); float percent = (level / (float)scale) * 100; But how do I get the battery usage details of apps installed on phone, including that of the screen, as shown in the image below? Sorry to disappoint you, but Android's power usage APIs are not public . so there is no official way to get what you want. But you can use reflection to access some private members and methods and make use of them. You can also check

I want to know the time spent by all applications running in an android device . I am getting all packages names using the following code .Please guide me how to link packages and the above method to get time spent by applications Here is the code List<PackageInfo> packs = getPackageManager().getInstalledPackages(0); for (PackageInfo pack : packs) { if (pack.firstInstallTime != pack.lastUpdateTime) { Log.i("n-names", pack.applicationInfo.loadLabel(getPackageManager()) .toString()); Log.i("n-install time", pack.firstInstallTime + ""); Log.i("n-uptime", pack.lastUpdateTime + ""); UsageStats

Since Android Lollipop, we have now an API for accessing apps usage stats. However, your app must be granted those permissions by the user. I know that for redirecting the user to those settings using Settings.ACTION_USAGE_ACCESS_SETTINGS. Now, my question is how do you know the user has granted you those permissions so that you can stop redirecting him to the settings. Thanks! tzanou you can simply query usagestats with daily interval and end time the current time and if nothing is returned this means the user hasn’t granted permissions @TargetApi(Build.VERSION_CODES.LOLLIPOP) public boolean
