Class Test {
public String name;
public String sirName;
}
ArrayList<Test> res = new ArrayList<Test>();
res.add(…);
res.add(…);
Comparator<Test> comperator = new Comparator<Test>() {
@Override
public int compare(Test object1, Test object2) {
return object1.name.compareToIgnoreCase(object2.name);
}
};
Collections.sort(res, comperator);

Unfortunately you can’t.

The only way to delete a directory from a Android device connected with adb is to execute:

adb shell rm -r /path/to/dir
