Question

I develop mostly for iPhone and have started very recently with Android.

Tried the hello world, but when hit run the emulator just shows a black screen with an Android logo shining.

package com.hyper.tuti;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class TutiActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // setContentView(R.layout.main);
        TextView tv = new TextView(this);
        tv.setText("Hello, Android");
        setContentView(tv);
    }
}

why is my simulator not working??

Answer 1

Yeah I’ve had emulator boot times of 5-10 minutes initially.

Hint

When you edit your AVD, there is an option to take a snapshot. What this does is when you close your AVD, it takes a snapshot and opens that next time, bypassing boot.

I have recently gotten back into Android development, and I now use Genymotion to run my emulators. It is based off of VirtualBox – it runs incredibly fast. I have not tried the Android Emulator in years so I cannot say whether or not it is any faster. I know my emulators start up almost instantly now and are not slow and buggy like before.
