Google Tag Manager displays "Invalid Macro"

Question

I tested Google Tag Manager for mobile devices, in particular Android, but when I try to getString(myKeyValue on the Container page, I get a message with the message "invalid macro").

Here is part of my code in my MainActivity:

 @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); txtHello = (TextView)findViewById(R.id.txtHello); btn = (Button) findViewById(R.id.btn); btn.setOnClickListener(new OnClickListener() { @Override public void onClick(View arg0) { String hello = mContainer.getString("hello"); long l = mContainer.getLong("long"); txtHello.setText(hello + l); } }); tagManager = TagManager.getInstance(this); ContainerOpener.openContainer(tagManager, CONTAINER_ID, OpenType.PREFER_NON_DEFAULT, null, new ContainerOpener.Notifier() { @Override public void containerAvailable(Container container) { mContainer = container; } }); } 

I added these permissions to the manifest:

 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.INTERNET" /> 

I have the correct Container_id because it shows the correct version after a software update.

And this is my assets / tagmanager / CONTAINER_ID.json file (of course, with the correct file name):

 { 'hello': 'hola', 'long' : '12345679' 

}

So, after my container is initialized, I click on the button that launches the code above, trying to get the values. But I get an error: "Invalid macro: hello" and "Invalid macro: long", also "Failed to convert '' to number"

This is a new service for mobile devices, but can anyone help me with this?

Answer 1

I found a problem for my business. I just downloaded the version from the web browser manager. It is important to add a rule that allows GTM to use this macro. Always come in handy here.

Remember to post your container version

For people who don’t get what dumazy refer to

you also need to enable it using Always or any other relevant rules.

Answer 3

In your json you use quotas of '123456' to determine the long, you should not:

 { 'string': 'hola', 'long': 123456, 'double': 123.123 } 

If you have additional problems, look: Android TagManager does not get the default value
