Obtenir la date d'installation de l'application sur Android

Question

Existe-t-il un moyen de connaître la "date à laquelle une application a été installée" sur un appareil Android.

J'ai effectué une recherche approfondie, mais incapable de trouver une réponse pertinente.

Impossible de trouver quoi que ce soit concernant la date d'installation de l'application dans la documentation / le code de PackageManager.

Merci beaucoup. Mahim.

Answer 1

ou celui-ci ( API Niveau 9 à partir de là !):

 long installed = context
    .getPackageManager()
    .getPackageInfo("package.name", 0)
    .firstInstallTime
;
 

Answer 2

Utilisez ce code:

 PackageManager pm = context.getPackageManager();
ApplicationInfo appInfo = pm.getApplicationInfo("app.package.name", 0);
String appFile = appInfo.sourceDir;
long installed = new File(appFile).lastModified();

Essayez un de ces

 /**
 * The time at which the app was first installed. Units are as per currentTimeMillis().
 * @param context
 * @return
 */
public static long getAppFirstInstallTime(Context context){
    PackageInfo packageInfo;
    try {
    if(Build.VERSION.SDK_INT>8/*Build.VERSION_CODES.FROYO*/ ){
        packageInfo = context.getPackageManager().getPackageInfo(context.getPackageName(), 0);
        return packageInfo.firstInstallTime;
    }else{
        //firstinstalltime unsupported return last update time not first install time
        ApplicationInfo appInfo = context.getPackageManager().getApplicationInfo(context.getPackageName(), 0);
        String sAppFile = appInfo.sourceDir;
        return new File(sAppFile).lastModified();
    }
    } catch (NameNotFoundException e) {
    //should never happen
    return 0;
    }
}
/**
 * The time at which the app was last updated. Units are as per currentTimeMillis(). 
 * @param context
 * @return
 */
public static long getAppLastUpdateTime(Context context){
    try {
    if(Build.VERSION.SDK_INT>8/*Build.VERSION_CODES.FROYO*/ ){
        PackageInfo packageInfo = context.getPackageManager().getPackageInfo(context.getPackageName(), 0);
        return packageInfo.lastUpdateTime;
    }else{
        ApplicationInfo appInfo = context.getPackageManager().getApplicationInfo(context.getPackageName(), 0);
        String sAppFile = appInfo.sourceDir;
        return new File(sAppFile).lastModified();
    }
    } catch (NameNotFoundException e) {
    //should never happen
