This is the content of the file: MainActivity.xml
It was working good I clicked the button and it opened the camera application on my device ! But as soon as I added this lines:
int i = Camera.getNumberOfCameras(); TextView age = (TextView) findViewById(R.id.textView1); age.setText(i);Im getting the error on my device say nned to force close.
I tried also instead age.setText(I); this:
age.setText(Integer.toString(i));I tried instead of id.textView1 also id.button1 but not working.
This is the content of activity_main.xml file:
This is the only two files I did changes.
I can make I did that on button click it will open the camera application on my device ! but I can't find how to show a message also when I click the button that will show how many cameras I have on the device. Im getting on my device when clicking the button an error say need to force close it if I move this 3 lines of the numberofcameras it will work good again.
