Hello,
I have trouble launching the WebBrowser with an Intent with a Button Click.
I try doing this in the onCreate Method of my Activity:
final Button getTheButtonBtn = (Button)
this.findViewById(R.id.ButtonTheButton);
getTheButtonBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
// Browser oeffnen mit url
Intent i = new Intent(Intent.ACTION_VIEW , Uri.parse("
http://www.url.com) );
startActivity(i);
}
});
Its in the View like this:
<Button android:text="@string/button_ButtonTheButton_hint"
android:id="@+id/ButtonTheButton" android:layout_width="wrap_content"
android:layout_height="wrap_content"></Button>
When i launch the Activity i get a force close with this in the log:
