在drawable文件夹中有大量的图像说超过100,我正在开发图像的动画应用程序.我使用imageview来显示GIF图像.我已经将Split gif图像的概念用于多个PNG格式的图像,然后使用它.

每当用户进入应用程序时,我可以看到内存越来越多,直到用户获取java.lang.OutOfMemoryError为止.

那么处理许多图像的最佳/正确的方法是什么？

以下是我的代码：

dog_animation.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/DogView"
android:orientation="vertical" >

<ImageView
    android:id="@+id/dog_animation"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_weight="0.19" />

dog_animation.xml(可绘制文件夹)

Dog_Animation.java

public class Dog_Animation extends Activity {

Timer timer = new Timer();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
    setContentView(R.layout.dog_animation);

    ImageView img = (ImageView) findViewById(R.id.dog_animation);
    img.setBackgroundResource(R.drawable.dog_animation);
    AnimationDrawable frameAnimation = (AnimationDrawable) img
            .getBackground();
    frameAnimation.start();

    timer.schedule(new TimerTask() {
        public void run() {
            Intent intent = new Intent(Dog_Animation.this,Man_Animation.class);
            startActivity(intent);
        }
    },10000);
}
}

现在的问题是当我尝试从一个活动移动到另一个具有相同的其他图像的动画,它给我的错误java.lang.OutOfMemory.

我尝试过如此多的不同解决方案

@Override
protected void onDestroy() {
    super.onDestroy();

    unbindDrawables(findViewById(R.id.DogView));
    System.gc();
}

private void unbindDrawables(View view) {
    if (view.getBackground() != null) {
        view.getBackground().setCallback(null);
    }
    if (view instanceof ViewGroup) {
        for (int i = 0; i < ((ViewGroup) view).getChildCount(); i++) {
            unbindDrawables(((ViewGroup) view).getChildAt(i));
        }
        ((ViewGroup) view).removeAllViews();
    }
}

所以别的,但任何解决方案都不适合我.请帮我解决这个问题.即使我已经提到http://androidactivity.wordpress.com/2011/09/24/solution-for-outofmemoryerror-bitmap-size-exceeds-vm-budget/这个链接,但没有解决问题.

解决方法

<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:largeHeap="true"/>
