  • 0

I have a big problem with my app as it crashes often but never at the same spot.

Before it was working fine but I had a method repeated in every app that checked for the language. I have decided to put the method in a static class called Utils and maybe this is the problem???

here is how all my activities start:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    //set up idioma
    sharedPrefs =PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
    idioma = sharedPrefs.getString("listPref2", "catala");
    idioma=Utils.updateLanguage(getApplicationContext(), idioma);

    setContentView(R.layout.list_event);

}

does this do memory leaks? should I avoid using the static class for this? how could I don not to repeat the same code 20 times?

the errors I get:

    should I avoid using the static class for this?

    I think it’s ok to use a static class but you have to keep in mind, that the context you use use should only be used within the lifetime of the application or activity object where you got it from. This means if you access the context object and the original object it is attached to is already destroyed, you might get a null exception.

    how could I don not to repeat the same code 20 times?

    One way to do this is to create a base Activity class which contains all of the common things that need to be done in all your activities. And then, just have each of your unique activities extend this common Activity class.

    For example, in your common Activity class:

    public CommonActivityBase extends Activity {
    public onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);

    //set up idioma
    sharedPrefs =PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
    idioma = sharedPrefs.getString("listPref2", "catala");
    idioma=Utils.updateLanguage(getApplicationContext(), idioma);

    }
    ...
}

    And in your activity classes:

    public ActivityA extends CommonActivityBase {
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstance);
        ....  // do other stuff specific to this activity
        setContentView(R.layout.list_event);
    }
    ....
}

public ActivityB extends CommonActivityBase {
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstance);
        ....  // do other stuff specific to this activity
        setContentView(R.layout.list_for_activity_b);
    }
    ....
}
