Контекст не работает над Glide при расширении приложения на android

Question

Привет в моем проекте Я использую Glide lib для загрузки изображения с сервера, тот же код работал нормально, но когда я расширяю свой класс до приложения для глобального контекста, я получение ошибки

Мой глобальный класс для контекста

public class GlobalAppContextSingleton extends Application { 
private static GlobalAppContextSingleton mInstance; 
private Context context; 

@Override 
public void onCreate() { 
    super.onCreate(); 

    GlobalAppContextSingleton.getInstance().initialize(this); 
} 
public static GlobalAppContextSingleton getInstance() { 
    if (mInstance == null) mInstance = getSync(); 
    return mInstance; 
} 

private static synchronized GlobalAppContextSingleton getSync() { 
    if (mInstance == null) mInstance = 
      new GlobalAppContextSingleton(); 
    return mInstance; 
} 

public void initialize(Context context) { 
    this.context = context; 
} 

public Context getApplicationContext() { 
    return context; 
}} 

В моем классе AndroidManifest

<application 
    android:allowBackup="true" 
    android:icon="@mipmap/ic_launcher" 
    android:label="@string/app_name" 
    android:largeHeap="true" 
    android:supportsRtl="true" 
    android:name=".GlobalAppContextSingleton" 
    android:theme="@style/AppTheme" 

    > 
    <activity 
     android:name=".Activitys.LoginActivity" 
     android:label="@string/app_name" 
     android:theme="@style/AppTheme" 
     android:screenOrientation="portrait"> 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 

      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 
    </application> 

Это фрагмент, где я использую LIB Glide для ПОС Ио ADING от сервера

public class ProfileFragment extends Fragment { 


    public ProfileFragment() { 
     // Required empty public constructor 
    } 
    TextView profile_txt_firstname,profile_txt_lastname,profile_txt_role; 
    ImageView profile_img_profilepic; 
    Context context; 
    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     // Inflate the layout for this fragment 


     View view = inflater.inflate(R.layout.fragment_profile, container, false); 
     preferenceData preference= new preferenceData(GlobalAppContextSingleton.getInstance().getApplicationContext()); 
     profile_txt_firstname=(TextView)view.findViewById(R.id.profile_txt_firstname); 
     profile_txt_lastname=(TextView)view.findViewById(R.id.profile_txt_lastname); 
     profile_img_profilepic=(ImageView)view.findViewById(R.id.profile_img_profilepic); 

     profile_txt_firstname.setText(preference.getString("FirstName")); 
     profile_txt_lastname.setText(preference.getString("LastName")); 

     String pic =preference.getString("ProfilePicture"); 
     byte[] decodedString = Base64.decode(pic, Base64.DEFAULT); 
     //Glide.with(GlobalAppContextSingleton.getInstance().getApplicationContext()) 
     Glide.with(context) 
       .load(decodedString) 
       .asBitmap() 
       .placeholder(R.mipmap.ic_launcher) 
       .into(profile_img_profilepic); 
//  Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length); 
//  profile_img_profilepic.setImageBitmap(decodedByte); 


     return view; 
    } 

    @Override 
    public void onAttach(Context context) { 
     super.onAttach(context); 
     this.context=context; 
    } 
} 

Ошибка я получаю

Пожалуйста, помогите мне в этом, что не так я сделал здесь

Answer 1

Использование getActivity() вы в фрагменте.

Glide.with(context) 
       .load(decodedString) 
       .asBitmap() 
       .placeholder(R.mipmap.ic_launcher) 
       .into(profile_img_profilepic); 

изменение

Glide.with(getActivity()) 
       .load(decodedString) 
       .asBitmap() 
       .placeholder(R.mipmap.ic_launcher) 
       .diskCacheStrategy(DiskCacheStrategy.ALL) 
       .into(profile_img_profilepic); 

Update Добавить .diskCacheStrategy(DiskCacheStrategy.ALL)

Glide.with(getActivity()) 
        .load(decodedString) 
        .asBitmap() 
        .placeholder(R.mipmap.ic_launcher) 
        .diskCacheStrategy(DiskCacheStrategy.ALL) 
        .into(profile_img_profilepic);
