Using getAssets() gives the error "The method getAssets() is undefined for the type ClassName"?

Question

I am trying to open a file which is in the assets folder. But using getAssets() gives the error given above. I know I have to pass the context from another activity, but I can't do that either as then another error comes-"The method onCreate(SQLiteDatabase, Context) of type ClassName must override or implement a supertype method". So I am stuck. Is there a better way of opening that file? Here is the line:

InputStream is = getAssets().open("file1.txt");

*Note: ClassName is not an activity, it's just a class, so getAssets() cannot work without passing context from another activity.

Edit: Here is the class and onCreate declaration:

public class DatabaseHandler extends SQLiteOpenHelper { @Override public void onCreate(SQLiteDatabase db) {//some stuff InputStream is = getAssets().open("file1.txt"); //more stuff } }

some java code would be nice man...

getAssets() is a method on Context.

I know I have to pass the context from another activity, but I can't do that either as then another error comes-"The method onCreate(SQLiteDatabase, Context) of type ClassName must override or implement a supertype method".

Since you declined to paste the source code where this is occurring, it is difficult to help you.

ClassName is not an activity, it's just a class

More specifically, it is a subclass of SQLiteOpenHelper.

so getAssets() cannot work without passing context from another activity.

A SQLiteOpenHelper gets passed a Context to its constructor, which you need to override.

Beyond all of this, if your objective is to package a database with your app, please use SQLiteAssetHelper, as it has solved this problem.

How about:

InputStream is = getActivity().getAssets().open("file1.txt");

Again an error comes saying "The method getActivity() is undefined for the type ClassName.".

Use getContext() Method. Set getContext().getAssets(). I hope it will works .Actually getAssets() is a method on Context . For more details you can visit Here
