如何获取 android app uids

系统刚启动的时候，会对每个app分配一个uid，

最简单的获取方式就是通过adb ，不过限于eng或userdebug版

adb pull data/system/packages.list d:\

当然最合理的方式是通过PackageManager

public List getUids() {
List<Integer> uidList = new ArrayList<Integer>();
pm = getPackageManager();
List<PackageInfo> packinfos = pm
.getInstalledPackages(PackageManager.GET_UNINSTALLED_PACKAGES
| PackageManager.GET_PERMISSIONS);
for (PackageInfo info : packinfos) {
String[] premissions = info.requestedPermissions;
if (premissions != null && premissions.length > 0) {
for (String premission : premissions) {
if ("android.permission.INTERNET".equals(premission)) {
// System.out.println(info.packageName+"访问网络");
int uid = info.applicationInfo.uid;
Log.i("test", "uid = " + uid);
// String name = pm.getNameForUid(uid);
// // textName.setText(name);
// Log.i("test", "name = "+name);
uidList.add(uid);
}
}
}
}
return uidList;
}
