Store your array

public boolean storeArray(Boolean[] array, String arrayName, Context mContext) {   

    SharedPreferences prefs = mContext.getSharedPreferences("preferencename", 0);  
    SharedPreferences.Editor editor = prefs.edit();  
    editor.putInt(arrayName +"_size", array.length);  

    for(int i=0;i



Load your array

public Boolean[] loadArray(String arrayName, Context mContext) {  

    SharedPreferences prefs = mContext.getSharedPreferences("preferencename", 0);  
    int size = prefs.getInt(arrayName + "_size", 0);  
    Boolean array[] = new Boolean[size];  
    for(int i=0;i
