Question

Another problem in my android application. When i click on home button, it exits from the application but saying Sorry, the application has stopped unexpectedly

The code for my home button is

ImageView home  =   (ImageView)findViewById(R.id.home1);
    home.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub
            kalma1.stop();
            Intent i =new Intent(Kalma1.this, null);
            i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            finish();
        }
    });

and the console says the following

GC_EXTERNAL_ALLOC freed 1110 objects / 70984 bytes in 77ms

Answer 1

If you want to finish only that activity then dont use any intent just write finish()

home.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub

            finish();
        }
    });
