Date and time of the applications last launch

Question

In my application, you need to get the date and time of the all applications last launch on the device. Can I somehow get this information by standard means?

you can get last launch app name but not last date time ,you can refer https://stackoverflow.com/questions/3290936/android-detect-when-other-apps-are-launched — Vij, Jun 06 '17 at 12:09

Just save the time on every launch

SharedPreferences sharedPref = PreferenceManager.getDefaultSharedPreferences(this);
long lastLaunchMillis = sharedPref.getLong("lastLaunch", 0);
if (lastLaunchMillis != 0) {
    Calendar lastLaunch = Calendar.getInstance();
    lastLaunch.setTimeInMillis(lastLaunchMillis);
    //last launch found, handle
}
sharedPref.edit().putLong("lastLaunch", Calendar.getInstance().getTimeInMillis()).apply();

Edit: For launch statistics of other apps, have a look at UsageStatsManager. You can find a sample on its usage here.

Thanks, but I need to know the time of the last launch of not only my application, but also other installed ones. – user1854307 Jun 06 '17 at 12:00
Your link helped me a lot. Thank you! – user1854307 Jun 06 '17 at 12:59
The link is only for >=`lollipop` devices . What about pre-lollipop devices? – Lim CHAN Sep 14 '17 at 09:04

You can do that with creating an Application class and set it from your app's manifest file. Step by step:

Create a class extends Application:

public class MyApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();

        // save date to sharedpref
        PreferenceManager.getDefaultSharedPreferences(this).
            edit().putLong("LAST_LAUNCH_DATE_MS", new Date().getTime()).apply();
    }
}

Set it to your app from manifest file:

<application
    android:name="com.my.project.MyApplication"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme">
    .....
    .....
</application>

You can get last launch time as milliseconds from SharedPreferences now.

That will not "get the date and time of **all** applications last launch on the device" (emphasis added). — CommonsWare, Jun 06 '17 at 12:19

 Object var10000 = this.getSystemService(USAGE_STATS_SERVICE);
UsageStatsManager usageStatsManager = (UsageStatsManager) var10000;
            Log.d("TAG", "" + usageStatsManager);

            List<UsageStats> queryUsageStats = usageStatsManager.queryUsageStats(INTERVAL_DAILY, currentTime - (long) 600000, currentTime);
            Log.d("TAG", "" + queryUsageStats);
long last_used;
for(i=0 , i<queryUsageStats  , i++){
 last_used = queryUsageStats .get(i).getLastTimeUsed();
                    Log.d("tag", "" + queryUsageStats );
}

here is the way you can do that, you will get time in epos time so you have to convert it to normal time format.
