I havee an android activity with two buttons, and a ViewFlipper. The two buttons simply flips to next and previous on the viewflipper.
I want to have exactly 38 Images to switch between, and so I have added them as ImageViews inside the ViewFlipper in the activity's xml file.
For some reason, it seems like the device has a memory limit, that is exceeded when i add more than 20-something imageviews. It works perfectly with 21, but not with 25. The images are only between 50-150 kb, so I don't really understand why a ASUS Transformer Pad TF300T shouldn't be able to handle it. Here is the java-code
import dk.fourway.divepool.R;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.animation.AnimationUtils;
import android.widget.Button;
import android.widget.ViewFlipper;
public class FlipperFourActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Set main.XML as the layout for this Activity
setContentView(R.layout.activity_flipper_four);
// Set the listener for Button_Next, a quick and dirty way to create a listener
Button buttonNext = (Button) findViewById(R.id.Button_next);
buttonNext.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
flipNext(view);
}
});
// Set the listener for Button_Previous, a quick and dirty way to create a listener
Button buttonPrevious = (Button) findViewById(R.id.Button_previous);
buttonPrevious.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
flipPrevious(view);
}
});
}
private void flipNext(View view){
// Get the ViewFlipper from the layout
ViewFlipper vf = (ViewFlipper) findViewById(R.id.flipper);
// Set an animation from res/anim: I pick push left in
vf.setOutAnimation(AnimationUtils.loadAnimation(view.getContext(), R.anim.push_left_out));
vf.setInAnimation(AnimationUtils.loadAnimation(view.getContext(), R.anim.slide_left));
vf.showNext();
}
private void flipPrevious(View view){
// Get the ViewFlipper from the layout
ViewFlipper vf = (ViewFlipper) findViewById(R.id.flipper);
// Set an animation from res/anim: I pick push left out
vf.setOutAnimation(AnimationUtils.loadAnimation(view.getContext(), R.anim.push_right_out));
vf.setInAnimation(AnimationUtils.loadAnimation(view.getContext(), R.anim.slide_right));
vf.showPrevious();
}
}
and here the xml, simplyfied, as there are many almost identical ImageViews
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"

finally the error message:
