Add a few questions:

 
Caused by: java.lang.IllegalStateException: Could not find constructor that hast just a (Context) argument for helper class class com.ishow.funnymap.database.DatabaseHelper 

Caused by: java.lang.NoSuchMethodException:  [class android.content.Context] 
/ / To see the error message should not be invoked to display constructed been emptied! 

 
public class DatabaseHelper extends OrmLiteSqliteOpenHelper {

private static final String DATABASE_NAME = "safford.db"; 
private static final int DATABASE_VERSION = 11; 
private final String TAG = "DatabaseHelper"; 

private Dao  connotationEssayDao; 
private Dao  postDao; 
private static volatile DatabaseHelper instance; 

public static void init (Context context) {

Ormlite use reflection, reflection class does not need to be confused.

I use

 
-Keepattributes Signature 

To avoid confusion generic
And see the error should be implicit structure was cleaned out!
I do not have a good solution!
You said not to be confused reflection, specifically how to operate it?
