Install

Add app_usage as a dependency in pubspec.yaml. For help on adding as a dependency, view the documentation.

Android

NB: Requires API level 21 as a minimum!

I.e. you need to set the min SDK version inside the android/app/build.gradle:

minSdkVersion 21

You need to add the following package to the manifest namespace in AndroidManifest.xml:

xmlns:tools="http://schemas.android.com/tools"

as well as the following permissions to the manifest:

    <uses-permission
        android:name="android.permission.PACKAGE_USAGE_STATS"
        tools:ignore="ProtectedPermissions" />

Below is an example of how the start of your manifest should look in the end

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="YOUR_PACKAGE_NAME_HERE"
    xmlns:tools="http://schemas.android.com/tools">

    <uses-permission
        android:name="android.permission.PACKAGE_USAGE_STATS"
        tools:ignore="ProtectedPermissions"/>

Usage

  void getUsageStats() async {
    try {
      DateTime startDate = DateTime(2018, 01, 01);
      DateTime endDate = new DateTime.now();
      List<AppUsageInfo> infos = await AppUsage.getAppUsage(startDate, endDate);
      setState(() {
        _infos = infos;
      });
    } on AppUsageException catch (exception) {
      print(exception);
    }
  }

Each AppUsageInfo object has the following public fields:

  /// The name of the application
  String get appName;

  /// The name of the application package
  String get packageName;

  /// The amount of time the application has been used
  /// in the specified interval
  Duration get usage;

  /// The start of the interval
  DateTime get startDate;

  /// The end of the interval
  DateTime get endDate;
