Question

I have made my application using android SDK 2.2 version and now when I am running my app on android SDK 4.0.3 it’s not running.

I have given the min and the max sdk in the manifest file.

I am new in android and want to run my app for the lower and higher versions both. Can anybody tell me how can I do this. Any help is appreciated.

Code for splash class

package com.Cricket_trivia.in;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.MotionEvent;

public class SplashScreen extends Activity {

    protected int _splashTime = 5000; 

    private Thread splashTread;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.splash);


        final SplashScreen sPlashScreen = this; 

        // thread for displaying the SplashScreen
        splashTread = new Thread() {
            @Override
            public void run() {
                try {                   
                    synchronized(this){
                        wait(_splashTime);
                    }

                } catch(InterruptedException e) {} 
                finally {
                    finish();

                    Intent i = new Intent();
                    i.setClass(sPlashScreen, K_trivia_cricketActivity.class);
                    startActivity(i);

                    stop();
                }
            }
        };

        splashTread.start();
    }
    @Override
    public boolean onTouchEvent(MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_DOWN) {
            synchronized(splashTread){
                splashTread.notifyAll();
            }
        }
        return true;
    }

}

Answer 1

The reason why your app is crashing on 4.0.3 but not 2.2 is most likely because you are performing an expensive operation on the UI thread. Blocking the UI thread is very bad practice… don’t do it!! Previous versions of Android (i.e. pre-ICS versions) didn’t care when you did this and let your app run as is. In 4.0 and above, however, the OS checks against this and crashes your app if you ever perform a potentially expensive operation on the UI thread (such as a network connection, etc.).

You have provided basically no information on what the problem is in your question, so that’s all I can really do to help you out.

Edit:

Does something like this work?

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.splash);
}

@Override
public boolean onTouchEvent(MotionEvent event) {
    if (event.getAction() == MotionEvent.ACTION_DOWN) {
        Intent i = new Intent();
        i.setClass(sPlashScreen, K_trivia_cricketActivity.class);
        startActivity(i);
    }
    return true;
}
