My problem is our game can switch into menu and setting
mode instantly but it will need 4-6 seconds to load texture, init GL render
mode eventually I just used 6 simple textures to create 6 sprites in game.
Please help me answer two questions:
1. How can I preload our assets in android os to start our game quicker?
2. In order to use a trick to create instance switch between activity, how can I retain my activity with GLSurfaceView state?
I order to help you understanding my situation, please read the following code:
The game using 3 activities as you can see in following configuration:
<application android:label="@string/app_name"
android:icon="@drawable/icon" android:allowBackup="true">
<activity android:name=".Menu" android:screenOrientation="portrait"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
android:launchMode="singleTop">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".ReTouch" android:screenOrientation="portrait" />
<activity android:name=".Preference" android:screenOrientation="portrait" android:theme="@android:style/Theme.NoTitleBar.Fullscreen" />
</application>
My .ReTouch class is a class that extended from RokonActivity (I am using rokon engine for my game), this engine will create a GLSurefaceView to render my game in OpenGL ES
You can get RokonAcitivity's source code here: http://code.google.com/p/rokon/source/browse/tags/release/1.1.1/src/com/stickycoding/Rokon/RokonActivity.java
public class ReTouch extends RokonActivity {
public static final int REPLAY_DELAY_INTERVAL = 1000;
private ReTouchGameBoard reTouchGame;
and .Menu, .Preference are two normal standard activity in an android application.
I am using this method to start and switch between activities:
playButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
soundPool.play(soundId, 1, 1, 1, 0, 1);
startActivity(new Intent(Menu.this, ReTouch.class));
}
});
settingButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
soundPool.play(soundId, 1, 1, 1, 0, 1);
startActivity(new Intent(Menu.this, Preference.class));
}
});
quitButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
soundPool.play(soundId, 1, 1, 1, 0, 1);
finish();
}
});
