Android SQLite Asset Helper error

Question

So I am attempting to use the Android SQLite Asset Helper to pre-package a database with my application and I have run into an issue. Here's a little bit of information to get started:

• Using Android Studio (gradle)
• I have modified build.grade to include compile 'com.readystatesoftware.sqliteasset:sqliteassethelper:+'
• I have my database zipped (workoutsDatabase.sqlite.zip) in my src/main/assets/databases folder

• my WorkoutsDatabaseHelper.java looks as follows (sorry for the bad formatting, the formatter is being stupid this morning!)

  import android.content.Context;
  
  import android.database.Cursor;
  
  import android.database.sqlite.SQLiteDatabase;
  
  import android.database.sqlite.SQLiteQueryBuilder;
  
  
  import com.readystatesoftware.sqliteasset.SQLiteAssetHelper;
  
  public class WorkoutsDatabaseHelper extends SQLiteAssetHelper {
  

  // All Static variables // Database Version private static final int DATABASE_VERSION = 1;

  // Database Name
  private static final String DATABASE_NAME = "workoutsDatabase.sqlite";
  
  
  
  public WorkoutsDatabaseHelper(Context context) {
      super(context, DATABASE_NAME, null, DATABASE_VERSION);
  }
  

Can anyone see why this might be thinking that a .jar file is a zip? and also, is there anything else I am missing to get this working properly?

Here is the error:

Error:: error reading /Users/rdeckert/AndroidStudioProjects/MyPR/app/libs/android-sqlite-asset-helper.jar; cannot read zip file

I tried updating the Zip file (database) and that didnt do anything.

Answer 1

Once I removed compile 'com.readystatesoftware.sqliteasset:sqliteassethelper:+' from the build.gradle it compiled and worked correctly.

Answer 2

I know I am late but once i also removed this line but this didnt help me, So what you need to do is:

Method 1: Try to clean your project in 'Build' Option.

Method 2: Clean and Rerun your project in 'RUN' Option.

Method 3: If above method didnt help you then restart you android Studio.

Medthod 4: Restart Your PC, this will surely removed the error.

Answer 3

You can use

    implementation 'com.readystatesoftware.sqliteasset:sqliteassethelper:2.0.1'
