POAndroid change local configuration doesn't work

copied!<p>I am building an application which comes in two languages, using a setting activity where the user can change the language. Once the user has selected any language, I want to save his/her choice so when the application is launched again, the new language will appear. I have done everything connected to layouts in different languages and different orientations.</p> <h3>My problem</h3> <p>when I launch the application, It always launches in the <code>English</code> language, although I print the locale language and the result is <code>Arabic</code>.</p> <h3>Hint</h3> <p>when the user changes the language from the setting activity, and he/she presses save, the application is working perfectly in the new language. Unfortunately, when restarting the application, it is not started in this new language.</p> <h3>My code</h3> <p><strong>Tags.java</strong> - A class which contains but three strings:</p> <pre><code>public class Tags { public final static String LANGUAGE = "Language"; public final static String ENGLISH_LANGUAGE = "en"; public final static String ARABIC_LANGUAGE = "ar"; } </code></pre> <p><strong>Splash activity</strong> - The activity where the application starts:</p> <pre><code>someData = getSharedPreferences(filename, 0); android.content.SharedPreferences.Editor editor = someData.edit(); if (!someData.contains(Tags.LANGUAGE)) { editor.putString(Tags.LANGUAGE, Tags.ENGLISH_LANGUAGE); Locale locale = new Locale(Tags.ENGLISH_LANGUAGE); Locale.setDefault(locale); android.content.res.Configuration config = new android.content.res.Configuration(); config.locale = locale; getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics()); Setting.setLanguage(Tags.ENGLISH_LANGUAGE); } else { String currentLanguage = someData.getString(Tags.LANGUAGE, Tags.ENGLISH_LANGUAGE); Setting.setLanguage(currentLanguage); Log.e("currnetLanPHone", Setting.getLanguage()); if (currentLanguage.equalsIgnoreCase(Tags.ENGLISH_LANGUAGE)) { Locale locale = new Locale(Tags.ENGLISH_LANGUAGE); Locale.setDefault(locale); android.content.res.Configuration config = new android.content.res.Configuration(); config.locale = locale; getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics()); } else { Locale locale = new Locale(Tags.ARABIC_LANGUAGE); Locale.setDefault(locale); android.content.res.Configuration config = new android.content.res.Configuration(); config.locale = locale; getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics()); } } editor.commit(); </code></pre> <p>It confuses me because as I explained before, the language of the application is changed and the new layouts are loading when I change the language from the <code>Setting activity</code>.</p> <p>I am sure that you will ask me to give you the code of the <code>Setting activity</code> in order to compare what I have done in that activity with the splash activity. This code is as follows:</p> <p><strong>Setting activity</strong></p> <pre><code>if (s_language.getSelectedItem().toString().equalsIgnoreCase("English")) { editor.putString(Tags.LANGUAGE, Tags.ENGLISH_LANGUAGE); Locale locale = new Locale(Tags.ENGLISH_LANGUAGE); Locale.setDefault(locale); Log.e("Inside", Tags.ENGLISH_LANGUAGE); android.content.res.Configuration config = new android.content.res.Configuration(); config.locale = locale; getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics()); Setting.setLanguage(Tags.ENGLISH_LANGUAGE); } else { editor.putString(Tags.LANGUAGE, Tags.ARABIC_LANGUAGE); Locale locale = new Locale(Tags.ARABIC_LANGUAGE); Locale.setDefault(locale); android.content.res.Configuration config = new android.content.res.Configuration(); config.locale = locale; getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics()); Setting.setLanguage(Tags.ARABIC_LANGUAGE); } editor.commit(); </code></pre> <p>The code is pretty simple, I used a spineer <code>s_language</code> from two values.</p> <p><em>A problem could be that, in the setting activity, when the user presses <code>save</code>, the <code>Setting</code> activity is finished. In the <code>splash</code> activity, I check for the language in the <code>oncreate</code> function, before continuing the activity and finishing it after doing a number of steps. I don't think that finishing the activity is the problem, but I just told you in order to make the image clear.</em></p> <p>How can I resolve this issue?</p>
