  • Format the question code.

  • Possible duplicate of Onclick problem, I cannot pass Array information to a text view

  • Did you duplicate the question? By the way, the problem is elsewhere, but the solution is the same as your other question.

  • @Bacco The error here is another, it is a matter of not declaring the Activity in the Manifest. This possible duplicate is error is in the permission. Perhaps they were unsuccessful in drafting the questions.

    @seamusd actually has a number of them with various problems, which is worse.

have you declared this activity in your AndroidManifest.xml?

You did not declare Activity Link on Androidmanifest.xml

    +1 by the remark. At first the error is this, but soon he will come across the issue of permission Android 6.0. Just write! =)
