Question

我想获取已安装应用程序的列表。但是需要排除默认的内置应用程序。像蓝牙，App库一样。

预先感谢您的帮助

Answer 1

使用此方法

private void getApps() {
    List<ApplicationInfo> totallist = getPackageManager().getInstalledApplications(0);
    List<ApplicationInfo> installedlist = new ArrayList<>();
    List<ApplicationInfo> defaultlist = new ArrayList<>();
    for (int i = 0; i < totallist.size(); i++) {
        if ((totallist.get(i).flags & ApplicationInfo.FLAG_SYSTEM) == 0) {
            installedlist.add(totallist.get(i));
        }

        if ((totallist.get(i).flags & ApplicationInfo.FLAG_UPDATED_SYSTEM_APP) != 0) {
            defaultlist.add(totallist.get(i));
        }
    }
    Log.d("totallist apps", String.valueOf(totallist.size()));
    Log.d("installedlist apps", String.valueOf(installedlist.size()));
    Log.d("defaultlist apps", String.valueOf(defaultlist.size()));
}

非系统应用程序有两种类型：

从Google Play商店下载的应用制造商在设备中预加载的应用下面的代码将返回上述所有应用程序的列表：

ArrayList<ApplicationInfo> mAllApp = 
        mPackageManager.getInstalledApplications(PackageManager.GET_META_DATA);

for(int i = 0; i < mAllApp.size(); i++) {
    if((mAllApp.get(i).flags & ApplicationInfo.FLAG_SYSTEM) == 0) {
         // 1. Applications downloaded from Google Play Store
        mAllApp1.add(mAllApp.get(i));
    }

    if((mAllApp.get(i).flags & ApplicationInfo.FLAG_UPDATED_SYSTEM_APP) != 0) {
        // 2. Applications preloaded in device by manufecturer
        mAllApp1.add(mAllApp.get(i));
    }
}
