Android 是一个基于 Linux 的开源操作系统,主要用于触摸屏设备,如智能手机和平板电脑。它由 Google 开发和维护,并基于 Android 开放源代码项目(AOSP)。
获取 Android 设备上安装的应用程序的大小和日期信息,可以使用以下方法:
PackageManager
类查询应用程序信息。import android.content.pm.PackageManager;
import android.os.Build;
...
private void getAppInfo() {
PackageManager pm = getPackageManager();
String packageName = "com.example.app"; // 替换为您的应用包名
PackageInfo packageInfo = pm.getPackageInfo(packageName, PackageManager.GET_META_DATA);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
long installedTime = packageInfo.firstInstallTime;
long updateTime = packageInfo.lastUpdateTime;
Log.d("AppInfo", "Installed time: " + installedTime + ", update time: " + updateTime);
} else {
long installedTime = packageInfo.installedTime;
long updateTime = packageInfo.updateTime;
Log.d("AppInfo", "Installed time: " + installedTime + ", update time: " + updateTime);
}
}import android.content.pm.ApplicationInfo;
import android.os.Build;
...
private void getAppInfo() {
ApplicationInfo appInfo = getApplicationInfo();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
long installedTime = appInfo.firstInstallTime;
long updateTime = appInfo.lastUpdateTime;
Log.d("AppInfo", "Installed time: " + installedTime + ", update time: " + updateTime);
} else {
long installedTime = appInfo.installedTime;
long updateTime = appInfo.updateTime;
Log.d("AppInfo", "Installed time: " + installedTime + ", update time: " + updateTime);
}
}以上两种方法都可以获取应用程序的大小和安装日期信息,可以根据实际需要进行选择。ApplicationInfo
