How to write this code in extension.

blocks(1)
blocks(1)808×152 19 KB

WE CAN EASILY DO IN BLOCKS.

tinyDb.getDataValue(myTag,YailList.makeEmptyList())

But Its Not Working in Extension.

 @SimpleFunction(description = "Get Tag Value as and Empty YailList")
public void getTinyList(String myTag) {
  ArrayList<String> Ins = new ArrayList<>();

    Ins = getArr(tinyDb.getDataValue(myTag,YailList.makeEmptyList()));
    Ins.add("One");
    Ins.add("Two");

  tinyDb.StoreValue(myTag,YailList.makeList(Ins));
  
}

public  ArrayList<String> getArr(YailList values) {
    ArrayList<String> Strl = new ArrayList<>();
    for (String val : values.toStringArray()) {
      // parsed String
      String d = String.valueOf(val);
      Strl.add(d);
    }
    // and now you have the double list
    return Strl;
  }

Following Line Producing Error
Ins = getArr(tinyDb.getDataValue(Tabs,YailList.makeEmptyList()));

                ^

@Taifun 's extension

used SharedPreferences, you may want to have a look.

This happens when you grow with copy-pasting. It is not a bad practice, but at least try to understand what code says before proceeding.

You should check Tiny DB source.

GetValue method accepts two parameters: key and default value

getDataValue accepts just one parameter: key

Can we use System.out.println("App Inventor \n"); while Writing Extension ? for Live Testing Purpose.

It won't work. That is not an android java function.

Yes, you can use it.

To get logs for specific tag, run this command:

adb logcat -s TagName

Since when? Someone needs to explain this to me.

25

Give it a try, you will understand.

26

It doesn't compile for me :confused: It never worked.

Currently I am Using .


@SimpleFunction(description = "TesterMethod")
public String tesTing(String txt) {
testingTxt = testingTxt + "\n" + txt;
return testingTxt;
}

This will Work While Runtime .
I am Using Linux Mint OS.

Sometimes I don't see Log.d() output in logcat so I always use it in conjugation with System.out.
